The SIM card interface 195 may also be compatible with different types of SIM cards. The SIM card interface 195 may also be compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to realize functions such as communication and data communication. In some embodiments, the electronic device 100 employs esims, i.e.: an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

The software system of the electronic device 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. In the embodiment of the invention, taking an Android system with a layered architecture as an example, a software structure of the electronic device 100 is illustrated.

Fig. 2 is a software architecture block diagram of an electronic device according to an embodiment of the application.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, from top to bottom, an application layer, an application framework layer, a An Zhuoyun line (Android runtime) system layer, and a kernel layer, respectively.

The application layer may include a series of application packages.

As shown in fig. 2, the application package may include applications such as cameras, calendars, maps, WLANs, bluetooth, music, video, short messages, mailboxes, weChat, WPS, etc.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 2, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture.

The telephony manager is for providing communication functions of the electronic device. Such as the management of call status (including on, hung-up, etc.).

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android runtime is responsible for scheduling and management of the android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system layer may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

The workflow of the electronic device 100 software and hardware is illustrated below in connection with capturing a photo scene.

When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into the original input event (including information such as touch coordinates, time stamp of touch operation, etc.). The original input event is stored at the kernel layer. The application framework layer acquires an original input event from the kernel layer, and identifies a control corresponding to the input event. Taking the touch operation as a touch click operation, taking a control corresponding to the click operation as an example of a control of a camera application icon, the camera application calls an interface of an application framework layer, starts the camera application, further starts a camera driver by calling a kernel layer, and captures a still image or video by the camera 193.

Typically, an electronic device may have a number of different applications installed thereon, which may provide different types of services to a user. Illustratively, FIG. 3 shows a management schematic of an existing application. Referring to (a) in fig. 3, an album application 31, a music application 32, a video application, an instant chat application, a game application, and the like are installed in the electronic device. The electronic device may receive a touch operation initiated by a user and start a corresponding application program to run in the foreground of the electronic device, and for example, when the electronic device detects that the user clicks on the album application 31, the electronic device may run the album application 31 in the foreground.

In order to improve the smoothness of user operation, the electronic device may run, in addition to the application program in the foreground, a part of the application program in the background, and the application program in the background, in the prior art, is often an application program started by the user in the process of using the electronic device. Illustratively, as shown in (b) of FIG. 3, the electronic device may respond to a user clicking on a control of the album application 31 to run the electronic device album application 31. If the electronic device detects the main interface return operation initiated by the user, the electronic device may return to the main interface of the electronic device at 10:01, i.e. return to the main interface shown in (a) of fig. 3. At this time, the electronic device detects that the user clicks the control of the music application 32 at 10:02, and generates the operation interface of the music application 32, as shown in (c) in fig. 3, in which case the album application 31 may remain in an operating state in the background of the electronic device although not operating in the foreground. At this time, the user may initiate a sliding operation at the lower boundary of the screen of the electronic device, and the electronic device may display the preview interface of each application program started by the user in response to the sliding operation, where the preview interface 33 includes the preview interface 33 of the application program running in the foreground (such as the music application 32) and the preview interface 34 of the application program running in the background (such as the album application 31), and of course, may also include the application program that has finished running, such as the preview interface 35 of the video application, as shown in (d) in fig. 3, where the order of displaying the hierarchy among the application programs is specifically determined according to the order in which the application program is started in the foreground. If the electronic device detects that the user clicks on the preview interface 34, it indicates that the user needs to switch from the music application 32 to the album application 31. If the album application 31 is running in the background, the electronic device can immediately run the album application 31 in the foreground at this time without reloading the album application 31 and restarting the album application, thereby greatly improving the loading speed of the application program and realizing smooth switching among the application programs.

However, in the actual use process of the electronic device, the electronic device cannot keep all the application programs started by the user running in the background due to the limited device resources and too high resource occupancy rate of part of the application programs.

Case 1: the background of the electronic device has run 5 applications, and the 5 applications occupy 90% of the device resources of the electronic device. At this time, if the electronic device needs to start a new application program, and running the application program needs to call 20% of device resources of the electronic device, in this case, the electronic device needs to close a part of application programs in background running, so that the electronic device can run normally.

Case 2: the electronic device is provided with a part of game application, and when the electronic device runs the game application, a large amount of hardware resources are required to be occupied, so that if the game application is maintained to run in the background, the utilization rate of the hardware resources in the electronic device is reduced, and in general, the application program of the type is closed to run in the background.

Therefore, although the electronic device may maintain the application program in the background running, in some cases, it is necessary to close some of the application programs running in the background to ensure the normal running of the electronic device, and reserve enough resources to run the application program newly started by the user. Therefore, how to reasonably manage the application programs running in the background directly affects the use experience of the user and the smoothness of the operation of the electronic equipment. The existing management technology for the application programs running in the background can be mainly divided into the following three modes:

mode 1: the applications that need to be closed are determined based on the order in which the applications are run in the background.

As shown in fig. 3 (d), the electronic device may display preview interfaces of each started application program, where the level of the preview interface of each application program is determined by the order in which the application program runs in the background, the preview interface of the application program running in the background first is at the bottom layer, such as the preview interface 35 of the video application, and so on, and the preview interface of the application program running in the foreground or finally running in the background is at the top layer, such as the preview interface 33 of the music application 32. It should be noted that, if there are more started applications, the page displaying the preview interface of the started application may be provided with the maximum number of display interfaces, for example, the number of display interfaces in (d) in fig. 3 is 3, and the interfaces of other applications after the 3-level may be hidden, and the preview interface of the other levels displayed in the current page may be switched through the sliding operation, so as to determine the preview interface of the application running earlier than the background.

When the electronic equipment needs to close part of background application programs under the condition of insufficient resources, the application program which is operated in the background at first can be selected as the application program which needs to be closed according to the sequence of each application program which is operated in the background at present, namely, the application program of which the preview interface is positioned at a lower layer. It should be noted that, the application program with the preview interface displayed in the page is an application program started by the user, and is not an application program running in the background, so that part of the application programs may already end to run in the background, but the preview page corresponding to the application program, namely, the page "tombstone" is still reserved in the page. The electronic device can determine the application program with the preview page at the bottommost layer from the application programs of the non-page 'tombstone', and can finish the operation of the application program operated at the bottommost layer if the resources of the electronic device are insufficient after the operation of the application program at the bottommost layer is finished, and the like until the resources of the electronic device meet the operation requirements.

However, when the application program running in the background is managed in the above manner, the application program commonly used by the user, such as the instant chat application, may be closed, which may cause the user to fail to receive the information sent by the chat object in real time, so that the accuracy of the background application program management is lower.

Mode 2: the application of the type of the holding part runs in the background.

The electronic device may be preset with an application list maintained in a background running state, and in the case of insufficient resources, the electronic device may keep the application program in the application list running in the background, and end running the application program not in the application list. For example, the application list includes email/instant chat (email/INSTANT MESSAGING, email/IM) applications, i.e. applications belonging to the email/IM type, which the electronic device keeps running in the background, such as email applications, weChat applications, whatsapp applications, etc., while non-email/IM applications are closed in case of insufficient resources.

However, in general, the applications of the common email/IM type for the user are limited, if all the applications of the common email/IM type are kept running in the background and a large number of applications of the common email/IM type for the user are closed, the common applications are frequently closed and frequently started, and the applications of the unusual email/IM type occupy the resources of the electronic device, so that not only is the resources of the electronic device wasted, but also the efficiency of switching the applications is reduced, and the use experience of the user is reduced. It can be seen that the above management accuracy for the application program is also low.

Mode 3: disabling part-type applications from running in the background

In a similar manner to the above, the electronic device may also set an application list that prohibits the background running, where the application in the application list automatically ends the application of the above type when the application runs in the background, or after a specific time (for example, running for 1 minute). For example, the application list includes application programs of game types, such as large-scale game applications such as the glowing of an owner and the overwhelming of life, and the electronic device needs to consume a large amount of hardware resources when keeping the application programs of the types running in the background, so that the maintenance difficulty is high, and the electronic device can use the application programs of the types as application programs forbidden to run in the background.

However, during the course of the game, the user often exits the game to perform other operations, such as replying to a message sent by the communication object or making a voice call. At this time, if the application program of the above type is run in the background or the background is run for more than a certain time, the running is ended, which may cause the application program to be frequently closed and frequently started, and for the application program with a larger data amount, the loading time may be worse, thereby further reducing the efficiency of application program switching and reducing the use experience of the user. Therefore, when the application program is managed in this way, the application program is greatly deviated from the actual use habit of the user.

Therefore, in the prior art, when the application program operated in the background is managed, the application program commonly used by the user is easy to finish operation, so that the situation that the application program commonly used by the user is frequently closed and frequently started occurs, the time consumption required by switching between applications is greatly increased, and the switching efficiency of the application program and the accuracy of application program management are reduced.

It should be noted that, the time intervals between the above-mentioned information collection trigger moments may be the same, in this case, that is, the electronic device is provided with a trigger period, and the running environment information of the electronic device is periodically obtained based on the trigger period, so as to manage the application programs running in the background of the electronic device.

Further, as another embodiment of the present application, the information collection triggering condition may be an event triggering condition, and if the information collection triggering condition is an event triggering condition, one or more of the following three cases may be included:

Case 1: when the application is started, the step S401 is specifically: and responding to a starting operation initiated by a user, running a third application indicated by the starting operation in the foreground, and acquiring the running environment information corresponding to the starting operation moment initiated by the user.

In this embodiment, the electronic device may respond to a startup operation initiated by a user for a locally installed application. Illustratively, FIG. 5 shows a schematic diagram of application launch provided by an embodiment of the present application. The starting operation comprises at least two modes, namely: an application is launched in a main interface of the electronic device and another application is launched in one application.

Fig. 5 (a) shows a schematic diagram of starting an application program in the main interface. Referring to (a) of fig. 5, icons of respective application programs currently installed in a main interface of the electronic device may be displayed by a user by clicking a corresponding icon to initiate a start operation for a related application. For example, when the user clicks the icon 51 of the album application, the electronic device receives a click operation on the icon 51, recognizes the click operation as a start operation, recognizes an application program corresponding to the click operation as a third application, that is, the album application as the third application, reads a related program running file of the album application from the local memory to run the album application, and displays an operation interface corresponding to the album application. In addition to running the third application, the electronic device may also obtain running environment information corresponding to when the third application is started.

Fig. 5 (b) shows a schematic diagram of starting one application program in another application program. Referring to fig. 5 (b), the electronic device is running an application, such as an instant chat application. In the operation interface of the instant chat application, there may be displayed an application return control 52, where the application return control 52 is specifically configured to return to the application program that was last invoked to run in the foreground, in this example, the application return control 52 displays an album application, that is, indicates that the electronic device is running the album application before the instant chat application is run in the foreground. If the electronic device detects that the user clicks the application return control 52, it indicates that the user initiates a start operation for starting the album application, at this time, the album application is identified as a third application, and the album application is run in the foreground, and the corresponding running environment information when the album application is started is obtained.

Fig. 5 (c) shows a schematic diagram of another way of starting another application from one application. The electronic device may initiate a slide-up operation at the edge under the screen in the interface as in (b) of fig. 5 to display the interface of the preview page of each application program started by the electronic device, i.e., (c) of fig. 5. The interface comprises a preview page of the application program running in the current foreground and a preview page of the application program running in the background. The user can activate the corresponding application program to the foreground operation by clicking any preview page in the interface, namely the clicking operation is the starting operation of the corresponding application program. For example, when the user clicks the preview page 53 of the album application, the electronic device may start the album application and apply the album application to the foreground operation, and at this time, the electronic device may further obtain the operation environment information corresponding to when the album application is activated to the foreground operation.

In this embodiment, after receiving a startup operation initiated by a user, the electronic device activates a third application corresponding to the startup operation to a foreground operation, and may further manage an application program running in the background, so that running environment information corresponding to the moment when the startup operation is received may be obtained.

Case 2: when the application is closed, the step S401 is specifically: and responding to an application closing instruction, ending the operation of a fourth application corresponding to the application closing instruction, and acquiring the operation environment information corresponding to the operation of the fourth application.

In this embodiment, the electronic device may respond to an application shutdown instruction for a locally installed application program, for example, the fourth application, where the application shutdown instruction may be initiated by a user or may be automatically generated by the electronic device. Illustratively, FIG. 6 shows a schematic diagram of application shutdown provided by an embodiment of the present application.

Fig. 6 (a) and (b) show schematic views of closing an application in an operation interface of the application. Referring to fig. 6 (a), the electronic device runs an instant chat application in the foreground, at this time, by initiating a sliding operation on the edge under the screen to display the interface of the preview pages of each application program started by the electronic device, as shown in fig. 6 (b), the preview pages located at the rightmost side are preview pages of the application program running in the foreground of the electronic device (the arrangement order of each preview page is determined according to the front-to-back order of each application program running in the foreground, and finally the preview page of the application program running in the foreground is at the rightmost side, while the preview page of the application program running in the foreground at the earliest is at the leftmost side, and is limited by the size of the display module of the electronic device, and part of the preview pages are in a hidden state, and each preview page can be viewed by sliding left and right), that is, the preview page of the instant chat application. At this time, if the electronic device receives the sliding operation about the preview page, it indicates that the user needs to close the instant chat application, and generates an application closing instruction about the instant chat application, closes the application program (i.e., the fourth application), and obtains the running environment information.

The electronic device may receive a right-slide operation of the user in the interface (b) of fig. 6 to change the preview page of the application program displayed in the screen, as shown in (c) of fig. 6, the preview page of the on-screen instant chat application of the electronic device may be hidden, and the preview page of the music playing application may appear. In this case, the user may initiate the above-mentioned sliding operation in the display area where the preview page of the application program to be closed is located, so as to close the corresponding application program, and the electronic device may generate the application closing instruction of the application program corresponding to the area according to the area corresponding to the sliding operation initiated by the user.

In one possible implementation manner, the application scenario in which the electronic device automatically generates the application closing instruction may be: in the process of running the application program, the equipment resources occupied by the application program are dynamically changed, if the application program starts a certain internal function, the occupied equipment resources are larger, the electronic equipment needs to configure the corresponding equipment resources for the application program to start the internal function, at the moment, the application program running in the background may need to be closed, at the moment, the electronic equipment can generate an application closing instruction and end the application program running in the background (namely, a fourth application) and acquire the running environment information corresponding to the constant Xuetime of ending the application.

In one possible implementation manner, the application scenario where the electronic device automatically generates the application closing instruction may further be: the electronic equipment can configure a maximum background operation duration for each application program which operates in the background; if the actual running time of any application program in the background running is detected to be longer than the maximum background running time, the electronic equipment can close the application program, at the moment, an application closing instruction of the corresponding application program can be generated, and corresponding running environment information is acquired.

In this embodiment, after the electronic device obtains the application closing instruction, the fourth application corresponding to the running application closing instruction is closed, where the running fourth application includes an application running in the foreground and an application running in the background, and after the application is closed, the device resource of the electronic device is changed, and at this time, the application running in the background can be managed, so that the running environment information corresponding to the moment of the fourth application is ended.

Case 3: when the operation mode of the electronic device is changed, the step S401 is specifically: and responding to a mode switching instruction of the electronic equipment, switching the operation mode of the electronic equipment, and acquiring the corresponding operation environment information when switching to the operation mode.

In this embodiment, the electronic device may manage the application programs running in the background, in addition to when the application programs are turned on and off, when the running mode of the electronic device is changed. The operation modes of the electronic device include, but are not limited to: normal operation mode, power saving operation mode, high performance operation mode, low battery operation mode, and the like. The electronic device may switch between a plurality of operation modes, and the switching of the operation modes of the electronic device may be initiated by a user or may be automatically performed by the electronic device.

Fig. 7 is a schematic diagram illustrating a user switching an operation mode of an electronic device according to an embodiment of the present application. Referring to fig. 7 (a), a user may enter a setup interface of the electronic device by clicking on an application icon "setup" on the electronic device, the setup interface being shown in fig. 7 (b). Through the setup interface, a user may set up a plurality of device items of the electronic device, such as wireless connections, bluetooth, etc., as well as settings for the operational mode, such as control 72. After the electronic device receives the click of the control 72 by the user, the electronic device may enter into a setting interface of an operation mode, as shown in (c) in fig. 7, where each operation mode that the electronic device may change, such as a normal operation mode 73, a power-saving operation mode 74, and a high-performance operation mode 75, may be displayed in the setting interface of the operation mode. The electronic equipment can receive the selection operation initiated by the user in the setting interface, determine the operation mode corresponding to the selection operation, and switch the electronic equipment to the corresponding operation mode.

Fig. 7 is a schematic diagram illustrating a user switching an operation mode of an electronic device according to another embodiment of the present application. Referring to fig. 7 (d), the electronic device may respond to a sliding operation initiated by the user above the screen, and display a corresponding quick setting pop-up window, where the quick setting pop-up window may quickly start and close a control of a corresponding functional module in the electronic device, such as a switch control of a bluetooth module, a switch control of a wireless communication module, a switch control of a mobile data function, and the like, and further includes a switch control 76 that whether to open a low battery mode. The electronic device may be in a normal running state when the switch control 76 is in an off state, and may change the state of the switch control 76 when receiving a click operation of the switch control 76 by a user, for example, switch the off state to the on state, where the electronic device may generate a mode switching instruction to switch the electronic device from the normal running state to the low power state.

In one possible implementation, the electronic device may be configured with multiple power thresholds, such that the overall power of the electronic device is divided into multiple distinct regions, such as a high power region, a medium power region, and a low power region, which may be associated with different modes of operation. In this case, when the actual power of the electronic device reaches a preset power threshold, the electronic device may generate a mode switching instruction to switch to an operation mode associated with the corresponding power region. Of course, when the electronic device needs to switch to the operation mode corresponding to the electric quantity area, a corresponding prompt message may also be generated, and, for example, fig. 8 shows a schematic display diagram of the prompt message in the mode switching provided in an embodiment of the present application. When the electric quantity of the electronic device reaches a preset electric quantity threshold, if the actual electric quantity of the electronic device is 20%, the electronic device can generate a prompt message of a switching mode to prompt the user to be in a lower electric quantity currently and inquire whether the user needs to switch to a corresponding low electric quantity mode, wherein the prompt message comprises two controls, one is a confirmation control 81 for confirming that the information is checked, and the other is a switching control 82 for switching the electric quantity mode. If the electronic device detects that the user clicks the confirmation control 81, it indicates that the user has determined that the current battery is in a lower power level and does not need to switch the operation mode, and at this time, the electronic device maintains the original operation mode of the electronic device; if the electronic device detects that the user clicks the switch control 82, it indicates that the user needs to switch the operation mode of the electronic device to the low-power mode, a mode switching instruction about the low-power mode is generated, and operation environment information of the electronic device is obtained.

In this embodiment, there are differences in available device resources of electronic devices in different operation modes, so when the operation modes of the electronic devices are switched, operation environment information at corresponding moments can be obtained, and a process of managing an application program running in the background is triggered.

In the embodiment of the application, the electronic equipment can acquire the operation environment parameters in a plurality of different states, for example, when the application program is switched, when the application program is closed and when the operation mode is changed, the available equipment resources of the electronic equipment can be changed in all three conditions, so that the application program operated in the background can be managed, the instantaneity of management operation can be improved, and the application program operated in the background is matched with the real-time available resources of the electronic equipment.

In this embodiment, when the electronic device meets a preset information acquisition trigger condition, the electronic device may acquire operation environment information at a corresponding moment, so as to determine, according to the operation environment information, an application usage habit of a user corresponding to the moment when the acquisition trigger condition is met. The above-described running environment information may specifically be information unrelated to an application program installed on the electronic device.

In one possible implementation, the operating environment information includes one or a combination of two or more of the following: location information, time information, touch information, system setting information, application information, and the like. The runtime environment information may include a plurality of runtime environment dimensions, and different runtime environment dimensions are used to describe feature information of one runtime environment.

In this embodiment, the application information is specifically used to determine an application that has been executed by the electronic device, that is, feature information for describing an application launch dimension. The application information may include: application package name, application start time, cleaned time, application use time, etc.

In this embodiment, the location information is used to determine a geographic location where the electronic device is located, that is, feature information for describing dimensions of a geographic environment; the location information may be a geographic coordinate point determined based on longitude and latitude, and may further include a scene type, a location name, and the like where the electronic device is located. For example, the scene types may be: malls, schools, offices, homes, etc.

In this embodiment, the time information is used to determine a specific time corresponding to the time when the above information acquisition triggering condition is satisfied, that is, the feature information for describing the time dimension. The time information may include corresponding year, month, date, week, and time information.

In this embodiment, the touch information is used to determine touch information initiated by a user on the electronic device when the acquisition trigger condition is satisfied, that is, feature information for describing a user operation dimension. The touch information comprises touch gestures initiated by a user on the electronic equipment, key information and the like. The touch gestures may include a touch trajectory, a touch type (e.g., click, double click, long press, and double press clicks, etc.), a touch duration, and so forth.

In this embodiment, the system setting information is used to determine information of a system state corresponding to the electronic device when the acquisition triggering condition is satisfied, that is, feature information for describing a dimension of the system state. The system setting information includes: and when the acquisition triggering condition is met, the information such as the operation mode, the equipment electric quantity, the resource occupation condition, the available resource condition, the network connection state, the access condition of the external equipment and the like corresponding to the electronic equipment.

Further, as another embodiment of the present application, fig. 9 shows a flowchart of a specific implementation of S401 provided by an embodiment of the present application, and referring to fig. 9, in this embodiment, acquiring operation environment information of an electronic device may specifically include the following steps:

In S4011, if the information acquisition triggering condition is satisfied, the original data fed back by the data acquisition module is received.

In this embodiment, a data acquisition module for acquiring original data corresponding to the operating environment information is configured in the electronic device. When the information acquisition triggering condition is met, the electronic equipment can send an acquisition instruction to the data acquisition module, and after the data acquisition module receives the acquisition instruction, the electronic equipment can feed back the original data related to the moment when the information acquisition triggering condition is met.

If the running environment information includes a plurality of running environment dimensions, different running environment dimensions may correspond to different data acquisition modules, that is, the original data corresponding to each running environment dimension is obtained through the corresponding data acquisition module.

For example, for raw data of the position dimension, it can be obtained by a positioning module; for the original data of the time dimension, the original data can be acquired through a clock module; for the original data of the touch dimension, the original data can be obtained through an interaction module (such as a touch screen, each physical key module and the like).

The above data collection process may specifically include two modes:

Mode 1: and directly acquiring the original data. The mode of directly acquiring the original data can be that each data acquisition module directly returns the original data to the electronic equipment after acquiring the original data.

Mode 2: and feeding back the original data to the cloud server. Illustratively, fig. 10 shows a schematic diagram of acquiring original data according to an embodiment of the present application. Referring to fig. 10, an electronic device may locally install a client program in communication with a cloud server, when the electronic device detects that a preset information acquisition triggering condition is met, each data acquisition module may transmit acquired original data back to the client program in the electronic device, where the client program may encapsulate the fed back original data, for example, into a class, and send an encapsulated class data packet to the cloud server, where the cloud server may be in a file after processing the original data. The sending of the class data packet to the cloud server may be implemented through a iBinder mechanism.

In S4012, principal component analysis is performed on the raw data, at least two operation environment dimensions are determined, and raw dimension parameters corresponding to the raw data in each operation environment dimension are respectively determined.

In this embodiment, after the original data fed back by the data acquisition module is received, principal component analysis may be performed on the original data to determine original dimension parameters corresponding to a plurality of different operating environment dimensions in the original data. When the original data is acquired through the data acquisition module, the data with different dimensions can be represented through the same parameter, and in order to better determine the application habit of a user, the data with a plurality of operation environment dimensions are required to be separated in a component mode so as to realize the dimension reduction operation on the original data.

The principal component analysis specifically determines at least two uncorrelated operation environment dimensions in the original data, and determines original dimension parameters of the operation environment dimensions. For example, the time dimension and the position dimension may be separated from the original data, and the position parameters corresponding to the position dimension and the time parameters corresponding to the time dimension may be determined respectively.

Further, as another embodiment of the present application, filtering operation may be performed on the raw data before performing the principal component analysis on the raw data. Correspondingly, the S4012 described above may include:

Step 1: and filtering the original data according to a preset filtering rule to obtain filtered original data.

Step 2: and carrying out principal component analysis on the filtered original data, and determining at least two operation environment dimensions.

In this embodiment, the original data fed back by the electronic device may be a plurality of data acquired in a period of time, where abnormal data may exist in the plurality of data, for example, data with abnormal values or empty data content, for the acquired data, the electronic device may identify the acquired data as abnormal data, perform filtering, thereby obtaining filtered original data that does not include abnormal data, and then perform principal component analysis on the filtered original data to determine the operation environment dimensions included in the filtered original data, and the original dimension parameters corresponding to the operation environment dimensions.

In one possible implementation manner, if the electronic device obtains the original data in the manner 2, that is, encapsulates the original data into a class and sends the class to the cloud server, the operation of S4012 may be completed by the cloud server. Optionally, the cloud server may send the original dimension parameters of each running environment dimension to the electronic device, so that the electronic device performs the operation of S4013.

In S4013, based on the running environment dimension, normalizing the original dimension parameter to obtain a normalized parameter.

In this embodiment, after obtaining the original dimension parameters corresponding to each operation environment dimension, the electronic device may perform normalization processing on the original dimension parameters based on the normalization standard of the corresponding operation environment dimension, so as to obtain normalized parameters that may correspond to the operation environment dimension, and after performing normalization processing on each original dimension parameter, may facilitate subsequent feature extraction on the original data.

In S4014, feature extraction is performed on the normalized parameters of each of the operation environment dimensions, so as to obtain feature information of the operation environment dimensions, and the operation environment information is generated based on the feature information of the operation environment dimensions.

In this embodiment, after normalizing each operation environment dimension, the electronic device obtains a corresponding normalized parameter, and may obtain feature information corresponding to the environment feature dimension through a feature extraction algorithm corresponding to the operation environment dimension. For example, for the position dimension, determining the scene type, the location name and the like corresponding to the position coordinate according to the normalized position coordinate; for the time dimension, the time range within which the time falls can be determined according to the normalized time: such as daytime or evening; the weekend, workday or special holiday; idle or busy, etc. And generating the operation environment information corresponding to the information acquisition triggering moment according to the characteristic information corresponding to each operation environment dimension.

In the embodiment of the application, the acquired original data is subjected to the processing such as dimension reduction, normalization and feature extraction to obtain the running environment information which can better represent the application use habit of the user, so that the prediction accuracy of the application use habit of the user can be improved, and the accuracy of the subsequent background running application set determination is improved.

In S402, determining a background running application set based on the running environment information; the background running application set comprises at least one first application allowed to run in the background; the first application is an application program which accords with application using habit of the user at the moment of meeting the information acquisition triggering condition.

In this embodiment, the electronic device may determine the application usage habit of the user by using the above running environment information, so that the first application included in the background running application set determined based on the above running environment information is also an application program that accords with the application usage habit of the user. The background running application set is specifically used for determining a first application allowed to run in the background, so that the subsequent electronic device can manage the application programs running in the background according to the background running application set, and the application programs running in the background are enabled to conform to application using habits of users.

In one possible implementation, the electronic device may record standard environmental information corresponding to each application that has been installed. If the running environment information corresponding to the information acquisition triggering time is matched with the standard environment information associated with the application program, the application program accords with the application using habit of the current user, the application program is identified as a first application, and the background running application set is generated based on the first application obtained through identification. The standard environment information corresponding to the application program is determined based on the historical usage record corresponding to the application program, and one application program can correspond to one or more standard environment information. Since the application can be run in different scenarios, times and device settings, the application can correspond to a plurality of different standard environment information.

Further, as another embodiment of the present application, fig. 11 shows a flowchart of a specific implementation of S402 provided in an embodiment of the present application. Referring to fig. 11, the step S402 may specifically include the following steps:

In S4021, generating a plurality of candidate application item sets based on all the application programs; each of the candidate application item sets contains at least one of the applications.

In this embodiment, a plurality of different applications are installed in the electronic device, and by arranging and combining the applications, an application set including at least one application, that is, the candidate application set, may be obtained.

If N application programs are installed in the electronic device, the candidate application item set that may be generated by the application program is specifically:

ItemNum is the total number of the application item sets.

In S4022, according to the running environment information and the application set information corresponding to the candidate application item sets, selecting a very frequent item set from all the candidate application item sets; the application set information comprises application information of each application program in the candidate application item set.

In this embodiment, the candidate application item set includes one or more installed application programs, and application information of each application program may determine application set information of the candidate application item set. The application information is specifically used for determining the usage habit of the corresponding application program. The application information may include: the application package name, the application starting time, the cleaned time, the application using place, the application using network state, the application using running mode, the application using historical electric quantity and the like. Therefore, the application set information including the candidate application item sets of the plurality of application programs may also include the plurality of information.

In one possible implementation, feature dimensions contained in application information of an application program are matched with runtime environment dimensions contained in runtime environment information, so that subsequent identification of extremely frequent item sets can be facilitated.

In one possible implementation manner, when the electronic device generates the application set information of the candidate application item set according to the application information of the application program, the application set information may be generated by performing cluster analysis on the application information of each application program in the candidate application item set. The cluster analysis is specifically used for determining common characteristic information of application information among a plurality of application programs in the candidate application item set, and determining application set information of the candidate application item set based on the common characteristic information.

For example, a candidate application set includes three applications, namely, application a, application B, and application C. The application information a of the application program a specifically includes: daytime use, home use, and connection WIFI use; the application information B of the application program B is specifically: daytime use, home use and mobile network connection use; the application information C of the application program C is specifically: night use, home use, mobile network use. Therefore, when the application information of the three application programs is subjected to cluster analysis, it can be determined that most of the application programs in the candidate application item set are used in the daytime, at home and through a connected mobile network, and at night and through WIFI belong to non-common features, and in this case, the application set information obtained after clustering is: daytime use, home use, and mobile network connection use.

In this embodiment, the electronic device may match the running environment information with application set information of the candidate application item set, and if the matching degree between the running environment information and the application set information of the candidate application item set is greater than a preset matching threshold, identify the candidate application item set as an associated application item set, and then select a very frequent item set from a plurality of associated application item sets. Wherein each subset in the extremely frequent item set is an associated application item set; the matching degree between the superset of the extremely-frequent item set and the application set information is smaller than or equal to the matching threshold, namely the superset of the extremely-frequent item set is an unoccupied item set.

In one possible implementation manner, the electronic device may perform preprocessing on the obtained running environment information, where the preprocessing includes performing dimension reduction processing on the information, converting the information into a one-dimensional array, calculating a support degree of a candidate application item set based on the converted one-dimensional array, selecting the candidate application item set with the support degree greater than a preset support threshold as a frequent item set, and determining a maximum frequent item set based on all the frequent item sets obtained by recognition.

Illustratively, FIG. 12 shows a schematic drawing of the selection of a very frequent item set provided by an embodiment of the present application. If the operation environment information contains position information, time information, gesture information and system setting information, the electronic equipment can combine the position information and the time information and extract the characteristics, and the two information are converted into a one-dimensional array for determining the space-time characteristics of the operation environment and an immediate space-time characteristic array; the electronic device can combine the gesture information and the system setting information and extract the characteristics, convert the two information into one-dimensional arrays, and determine the system characteristics of the operation environment, namely the system characteristic data, then integrate the two arrays to obtain a corresponding operation environment characteristic array, and determine the frequent item set based on the operation environment characteristic data. The electronic device is internally provided with application programs 1 to N, the application programs can be divided into a plurality of different candidate application item sets, and the support degree between the candidate application item sets and the running environment characteristic array is calculated based on each candidate application item set, so that a very frequent item set is identified.

In S4023, according to the application information and the running environment information of each application program in the maximum frequent item set, starting confidence degrees corresponding to each application program in the maximum frequent item set are calculated respectively.

In this embodiment, after determining the extremely frequent item set, the electronic device may perform confidence calculation based on the application information and the running environment information of each application program in the extremely frequent item set, so as to determine the starting confidence corresponding to each application program, so that the associated application program meeting the requirements may be partitioned based on the starting confidence.

In S4024, the application program with the start confidence coefficient greater than the preset confidence coefficient threshold is selected as a candidate application, and the background running application set is determined based on the candidate application.

In this embodiment, the electronic device may be configured with a corresponding confidence threshold, to select, from the extremely frequent item set, a first application that may run in the background, specifically: and the electronic equipment selects an application program with the starting confidence coefficient larger than the confidence coefficient threshold as a candidate application, and generates the background running application set based on the selected candidate application.

In one possible implementation manner, the electronic device may directly use the candidate application with the starting confidence coefficient greater than the preset confidence coefficient threshold as the first application, and generate the background running application set.

Further, as another embodiment of the present application, the step S4024 may specifically include the following steps:

In S4024.1, all the candidate applications and the running environment information are imported into a decision algorithm corresponding to each running environment dimension, and the first application corresponding to the running environment dimension is calculated.

In this embodiment, the electronic device may be configured with a corresponding decision algorithm, where the decision algorithm may be represented in various forms. The expression form can be a neural network, a decision tree, a decision correspondence table, and the like. The electronic device may import all candidate applications and running environment information obtained from the extremely frequent item set into a decision algorithm corresponding to the running environment dimension, where the decision algorithm may determine a candidate application with a matching environment parameter of the running environment dimension, that is, the candidate application is used as a first application corresponding to the running environment dimension, and the implementation manner may specifically be: when the electronic device imports the running environment information into the decision algorithm, the decision algorithm may determine a corresponding decision branch, and select an application matching the decision branch, that is, the first application, from the candidate applications.

For example, the electronic device includes a time dimension decision algorithm, which may be used to determine that the time of day and the time of night conform to the application program used by the user, and if the time information recorded in the running environment information is 13:00, the decision algorithm selects a branch corresponding to the time of day, and selects a candidate application that matches the branch, that is, the first application, from all candidate applications.

Illustratively, the decision algorithm may be a decision tree, which includes a plurality of different decision branches, and each decision branch may correspond to a running environment dimension, such as a system setup dimension, a location dimension, a time dimension, and an application scenario dimension. Illustratively, fig. 13 shows a schematic structural diagram of a decision tree according to an embodiment of the present application. Referring to FIG. 13, branches of various different operating environment dimensions are incorporated within the decision tree, the different branches being used to determine first applications associated with different operating feature dimensions. Wherein, the branch includes: device system branches, location information branches, time information branches, and application scenario branches. The electronic device may determine a corresponding branching route according to the operating environment information, and determine a first application of an operating environment dimension associated therewith through the corresponding branching route.

It should be noted that the decision algorithm is generated according to the application usage record in the user history process.

In S4024.2, the background running application set is generated based on the first applications corresponding to all the running environment dimensions.

In this embodiment, after determining the first applications corresponding to the dimensions of each running environment, the electronic device may integrate multiple first applications, for example, merge the same first applications, and reserve different first applications, so as to generate a background running application set.

In the embodiment, the application program which can be operated in the background can be determined in multiple dimensions through the decision algorithm generated based on the user using habit, so that the accuracy of the first application identification is improved.

In the embodiment of the application, the application programs are divided to generate a plurality of candidate application item sets, the extremely-frequent item sets are identified, the application programs matched with the running environment information can be identified in batches rapidly, and further screening is carried out according to the extremely-frequent item sets, so that the first application used to the user application is determined, and the accuracy of the background running application set is improved.

In S403, according to the second application running in the background at the moment when the information collection triggering condition is satisfied and the set of applications running in the background, the application program running in the background is managed.

In this embodiment, after determining the first applications allowed to run in the background, the electronic device may manage the application programs currently running in the background based on the background running application set recorded with all the first applications, so as to determine the application programs that need to be closed in the background running application and the application programs that need to be reserved.

Further, as another embodiment of the present application, the above S403 may specifically include the following three cases:
