Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a management method for preloaded applications according to an embodiment of the present application, where the method may be performed by a management apparatus for preloaded applications, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an intelligent terminal. As shown in fig. 1, the method includes:
step 110, when detecting that the application preloading event is triggered, acquiring application information of the preloaded first application program.
For example, the intelligent terminal in the embodiment of the present application may include terminal devices such as a smart phone, a tablet computer, a notebook computer, a handheld game console, and an intelligent appliance. And the intelligent terminal is provided with an operating system.
For example, the trigger condition of the application preloading event may be set according to an actual situation, and the embodiment of the present application is not particularly limited. For example, an application preloading event may be triggered when detecting that a user's action satisfies a preset condition (e.g., picking up a terminal, inputting a screen unlocking operation, inputting a terminal unlocking operation, or the like); or when detecting that the foreground application program is changed, triggering an application preloading event; or after the prediction process of the preloaded application is finished, an application preloading event can be triggered immediately (or after a preset time length is passed); or may be triggered at timed intervals, etc. After the application preloading event is triggered, the system may detect that the application preloading event is triggered by reading a flag bit or receiving a trigger instruction, and the like, and the specific detection method is not limited in this embodiment of the application.
The application information includes an application identifier of the application program that has been preloaded (i.e., the first application program), a preloading completion time, a launch prediction probability, and the like. The application identifier includes, but is not limited to, a package name or a process name. The preloading completion time is the time for completing the preloading operation corresponding to each preloaded application program. The completion of the preloading can be understood as completing the loading of the application program under the condition that a user is not visible, that is, pulling up a process corresponding to the application program, and playing an advertisement or animation and the like when the application program is started. The starting prediction probability is the probability that each application program is started at the next moment, and can be obtained by adopting a prediction model to predict according to the application program used at the current moment and the application program used at the previous moment. Alternatively, in order to reduce the number of applications to be monitored, the preset white list may be used to store the applications with the download quantity ranking Top50 in the application store, record only the usage data of the applications with Top50, and use the prediction model to perform prediction based on the usage data.
In the embodiment of the application, when the application preloading event is detected to be triggered, the application identifier, the preloading completion time and the starting prediction probability of the preloaded first application program are obtained. It should be noted that the application information of the first application is not limited to the application identifier, the preloading completion time, and the launch prediction probability listed above, and the embodiment of the present application is not particularly limited.
And step 120, closing at least one first application program according to the application information.
It should be noted that closing the first application may be ending a process related to the first application, and clearing the cache data downloaded by the first application. Since the first application is a preloaded application that is not displayed on the display screen, neither the loading nor closing process is visible to the user.
Illustratively, the preloading completion time corresponding to a first application program is sequentially acquired, and the current system time is acquired. A time difference between the current system time and the preload completion time is determined. And judging whether the time difference exceeds a preset time threshold value. And if the time difference is greater than or equal to a preset time threshold, closing the first application program corresponding to the preloading completion time. And if the time difference is smaller than a preset time threshold, determining that the first application program corresponding to the preloading completion time does not meet the closing condition temporarily. And judging whether each preloaded but un-started first application program meets the closing condition or not by adopting a similar mode, and executing closing operation on the first application program meeting the closing condition, thereby effectively clearing the memory space and avoiding the occurrence of the condition that the memory utilization rate is reduced due to the process resident memory of the first application program.
Optionally, when the execution of the preloading operation corresponding to the application preloading event is completed, the second application programs and the remaining first application programs are sorted in a descending order according to the starting prediction probability and the preloading completion time, and the set number of application programs after sorting is closed. Optionally, after the second application programs and the remaining first application programs are sorted in a descending order according to the starting prediction probability and the preloading completion time, the application programs in the set number after sorting can be closed after the time length is set after the sorting result is obtained. The method has the advantages that the newly preloaded second application program and the rest first application programs are mixed together for sequencing, the application programs with low starting prediction probability are closed, and the memory space can be cleared while the possibly opened application programs are ensured not to be closed. If so, the intelligent terminal preloads the application W (the predicted starting probability is 0.48), the application F (the predicted starting probability is 0.23), the application Y (the predicted starting probability is 0.21) and the application T (the predicted starting probability is 0.08) when the preloading operation corresponding to the application preloading event is completed; meanwhile, it is assumed that the remaining first applications are application H (predicted launch probability is 0.38) and application a (predicted launch probability is 0.21), respectively. Therefore, the applications W, F, Y, T, H and A are sequenced according to the starting prediction size, the applications Y and A have the same predicted starting probability, and the application Y is determined to be arranged before the applications A by combining the preloading completion time, so that the sequencing results are the applications W, H, F, Y, A and T. And after the preset time of the sequencing result can be obtained, closing the set number of application programs arranged at the tail of the queue. The preset time may be a system default time, and the set number may be a system default number or preset by a user according to an actual situation. Optionally, the user may be prompted in the form of a prompt box to select the number of applications to be closed, and so on.
And step 130, determining a second application program to be preloaded.
For example, the application to be preloaded may be an application that a user may open soon, and may be a fixed application that is set in advance, or an application that is predicted in a certain manner, and the like. The application to be preloaded may comprise one or more.
Alternatively, a prediction model may be used to predict the application to be preloaded. The prediction model may be a machine learning model, and the algorithm used may include a Recurrent Neural Networks (RNN), a Long Short-Term Memory (LSTM) network, a threshold cycle unit, a simple cycle unit, an auto-encoder, a decision tree, a random forest, a feature mean classification, a classification regression tree, a hidden markov, a K-nearest neighbor (KNN) algorithm, a logistic regression model, a bayesian model, a gaussian model, and a KL divergence (Kullback-Leibler) or the like.
Optionally, in the process that the user uses the terminal, a training sample may be collected, the training sample is adopted to train the preset initial model, and finally, a prediction model for predicting the application program to be preloaded is obtained. For example, the elements contained in the training sample may include a time sequence or an order sequence in which the application was opened; can include the time, place, frequency, etc. that the application was opened; the method can include the running state of the terminal, such as the on-off state of a mobile data network, the connection state of a wireless hotspot, the identity information of the connected wireless hotspot, the currently running application program, the previous foreground application program, the stay time of the current application program in the background, the last time the current application program is switched to the background, the plugging state of an earphone jack, the charging state, the battery power information, the screen display time and the like; and the data collected by sensors integrated in the terminal can be included, such as a motion sensor, a light sensor, a temperature sensor, a humidity sensor and the like.
For example, a suitable sample element may be selected according to the selected machine learning model, the selected machine learning model may be determined according to the selected sample element, and the model and the sample element may be selected according to requirements on prediction accuracy, a preset speed, and the like, which is not limited in the embodiment of the present application.
In the embodiment of the application, determining the second application to be preloaded may include performing prediction by using a prediction model based on historical usage data of the application, and determining the application to be preloaded according to a current output result of the prediction model.
And 140, preloading an application interface corresponding to the second application program based on the pre-created preloading active window stack.
It should be noted that the boundary coordinates corresponding to the preloaded active window stack are located outside the coordinate range of the display screen.
In the embodiment of the present application, the active window may be understood as a separate interface directly providing interaction and operation for a user, and different names may be used in different operating systems to name the interface. For ease of understanding, the following description will be made taking an Android (Android) operating system as an example.
In the Android system, the active window is called Activity. Activity is a component responsible for interacting with a user that provides a screen (which may be understood as a screen interface, rather than a display screen of an entity) for the user to interact to accomplish a task. In an android application, an Activity is usually a separate screen on which controls can be displayed and events of the user can be monitored and processed. In managing Activity, there are two concepts: task Stack and Stack. The Task corresponds to an application program, the Task is used for storing activities, one Task can store one or more activities, and the activities follow the principle of first-in first-out and last-in first-out. And the Stack is used for managing the Task, generally, one Stack manages the Task to which each Activity required to be shown by one screen belongs, and one Stack can manage one or more tasks, and of course, the Stack also follows the basic management principle of the Stack. The screens described herein are not necessarily completely separate display screens, and in the case of "two screens", the two screens may be only two regions of a complete display screen that independently display respective display contents. Of course, if the terminal has two or even more separate display screens, the "two screens" may also be two separate display screens.
In the Android system, multi-window modes are supported, which may include split screen mode, picture-in-picture mode, and free mode (FreeForm). In the multi-window mode, the Stack in which the application is located may have its own size (size), and may include upper, lower, left, and right coordinates in a coordinate system with the upper left corner of the terminal screen as the origin. For example, (a, b, c, d), which generally describes the boundary of a rectangle, the coordinates of the upper left corner and the coordinates of the lower right corner of the rectangle can be used for representation, i.e. the coordinates of the upper left corner of the rectangle are (a, b), and the coordinates of the lower right corner are (c, d), and such a rectangular area corresponds to the size of Stack. The in-application layout in the Stack is based on the size of the Stack, that is, the application interface corresponding to Activity is displayed within the boundary range of the size.
In the multi-window mode, multiple applications may be allowed to be visible, including both system and user visibility and system-only visibility. The system and the user can see the display on the display screen, and the user can see the display; system-only-visible means that the operating system is visible, but not the user, and may be obscured by foreground applications or displayed outside the display screen as the application is intended to implement.
In the embodiment of the application, the application interface of the application program to be preloaded is preloaded outside the display screen, and the preloading can be realized based on a multi-window mechanism of an operating system, and the size corresponding to the application program is set outside the display screen through the multi-window mechanism so as to achieve the purpose of being invisible to a user, so that the display of the display content of the foreground application program on the display screen is not influenced.
Generally, in the multi-window mode, there may be multiple types of stacks, for example, Home Stack represents a Stack displayed by a desktop application, App Stack represents a Stack displayed by a third-party application, and there may be other split-screen stacks, and contents contained in the three types of stacks may be displayed on a display screen, which are collectively referred to as application active window stacks in this embodiment. In the embodiment of the application, a preloaded active window Stack (preloaded Stack) is added to indicate a Stack displayed by a preloaded application, and the boundary coordinates of the preloaded Stack are set to be outside the coordinate range of a display screen, so that an application program to be preloaded can be displayed on the Stack. For the Android system, a Stack special for displaying preloaded applications can be newly built based on a multi-window mechanism of the Android system. In the embodiment of the application, the reason for newly building the Stack is that the newly built preloaded Stack can own size and visibility, so that the purpose of preloading outside a display screen is achieved.
In the embodiment of the application, the creation time of the preloaded Stack is not limited, and the preloaded Stack can be set to be in a resident state by default before the terminal leaves a factory, namely the preloaded Stack exists all the time; the method can also be established when the terminal is started or after the terminal is successfully unlocked; but also after an application preloading event is triggered (which may be before determining the application to be preloaded), and so on. Optionally, the preloading an application interface corresponding to an application program to be preloaded based on a pre-created active window stack includes: judging whether a pre-established preloading active window stack exists or not; if not, creating a preloaded active window stack according to a preset rule; and preloading an application interface corresponding to the application program to be preloaded based on the created preloading active window stack. The method has the advantages that after the application program to be preloaded is determined, whether the preloading Stack exists or not is judged, if yes, new construction is not needed, and if not, creation is carried out, so that system resources can be saved. It can be understood that, when the application program to be preloaded includes a plurality of application programs, that is, when a plurality of application programs need to be continuously preloaded in a short time, before the first application program to be preloaded starts to load, the preloaded Stack is already created, and then before the second application program to be preloaded starts to load, the preloaded Stack exists, and the above determination may not be necessary.
In the embodiment of the application, a specific process of preloading an application interface corresponding to an application program to be preloaded based on the preloaded Stack is not limited, and for example, the application interface may be drawn and displayed based on the size of the preloaded Stack.
According to the technical scheme of the embodiment, when the application preloading event is detected to be triggered, the application information of the preloaded first application program is acquired; closing at least one first application program according to the application information; determining a second application program to be preloaded; and preloading an application interface corresponding to the second application program based on the pre-created preloading active window stack. By adopting the technical scheme, when the next preloading event is triggered, a part of the preloaded application programs can be closed so as to reasonably clear the memory resources of the intelligent equipment and avoid the influence on the memory utilization rate of the intelligent terminal caused by the resident process of the preloaded application programs; the application interface of the application program needing to be preloaded can be preloaded based on the preloading active window stack established outside the display screen, the starting speed of the target application program is improved, and the display of the display content of the foreground application program on the display screen is not influenced.
In some embodiments, the preloading an application interface corresponding to the second application (i.e., the application to be preloaded currently determined by the prediction model) based on the pre-created preload active window stack includes: creating a target process corresponding to the second application program; creating a task stack corresponding to the second application program in a pre-created preloading active window stack; starting an active window corresponding to the second application program in the task stack based on the target process; drawing and displaying an application interface corresponding to the second application program based on the started active window. The advantage that sets up like this lies in, can draw and show the application interface of second application based on the preloading activity window stack outside the screen coordinate range, can not disturb the operation and the demonstration of foreground application, guarantees system stability, effectively improves the speed when the target application starts simultaneously. While creating the target process, an initialization process of the target process may also be included. In the execution process of the above steps, preloading of other resources may also be involved, such as application service starting, memory allocation, file content reading, network data acquisition, and the like.
In some embodiments, further comprising: and sending a fake focus notification to the second application program, and keeping continuous drawing and display updating of an application interface corresponding to the second application program in a preset time period based on the fake focus notification. The advantage of this arrangement is that the drawing and displaying of the application interface can be completed under the condition that the second application program obtains the focus and is visible to the system, the completion degree of preloading is improved, and the focus of the foreground application is not affected. The focus in the embodiment of the present application is also referred to as an input focus, and the fake focus is independent from the focus corresponding to the foreground application. Generally, for the current Android system, a focus is unique, for example, input operations such as touch and the like only take effect on the focus, the system end and the application end are consistent for inputting focus information, and once the system end modifies the input focus information, the system end sends information that the input focus information changes to the application, so that the method ensures that the input focus information of the system end and the application end is consistent. In the embodiment of the application, the purpose that the application end can forge the focus is achieved by separating the mode that the system end and the application end input the focus information. Specifically, in the embodiment of the application, the focus information is forged for the preloaded application, so that the preloaded application has the focus information, and the focus information of the system end is still correct, so that the preloaded application can be drawn normally, and the purpose of full loading is achieved. The focus exists in the system end and the application end, which can be regarded as a server end (server) and a client end (client), the system end records the application with the focus, and the application end stores a flag bit (flag) to identify whether the application has the focus. The time for forging the input focus can be that when a new window of the Android window system is added and the focus needs to be updated, a forged focus notification is generated and sent. The method for forging the focus may be a method for changing the focus of the window by calling the client end of the window, so that the window acquires the focus. Specifically, the forged focus notification can be sent based on a Binder mechanism, which is the most common mode of interprocess communication of the Android system and adopts a c/s architecture, i.e., a client/service architecture.
In the embodiment of the present application, the preset time period may be designed according to actual situations, and may be, for example, within a fixed time length range after the start of the preloading, or a time period from the start of the preloading to the completion of the preloading, and the like. In some embodiments, the length of the preset time period includes a playing time length of a start advertisement or a start animation in the application program to be preloaded. Some application programs usually play some advertisements or animations during the starting process, the playing time of the advertisements or animations usually ranges from 3 seconds to ten seconds, and during the playing of the advertisements or animations, a user may not have any operation and only wait for the completion of the playing, which wastes valuable time of the user. The method and the device have the advantages that the starting advertisement or the starting animation can be played out of the screen before the target application program is started, and when the target application program is started, the main page or other user operable interfaces of the application program can be directly accessed, so that the operable time point of the target application program is further advanced, and the waiting time is reduced.
In some embodiments, after preloading an application interface corresponding to an application program to be preloaded based on a pre-created preloading active window stack, the method further includes: and when an operation instruction of a target application program is received, transferring an application interface corresponding to the target application program contained in the preloading active window stack to the display screen for displaying, wherein the target application program comprises a second application program and a first application program. The method has the advantages that when the target application program really needs to be started, the drawn application interface is directly migrated to the display screen to be displayed, the application interface can be rapidly switched, and the starting speed is improved.
In some embodiments, the migrating an application interface corresponding to the target application program included in the preloaded active window stack to the display screen for display includes: migrating a task stack corresponding to the target application program contained in the preloading active window stack to the top of an application active window stack; and updating the size information, the configuration information and the visibility of the task stack to realize that the application interface corresponding to the target application program is displayed on the display screen. The advantage that sets up like this lies in, can guarantee the stability of interface migration process, guarantees that the card screen can not appear in the recovery process, the black screen or the migration speed is slow scheduling problem.
For some terminals, especially mobile terminals such as mobile phones and tablet computers, in order to facilitate the use of users, the display modes of the display screen generally include vertical screen display and horizontal screen display, many applications display by default in the vertical screen mode, some applications display by default in the horizontal screen mode (such as some network games), and some applications switch the horizontal and vertical screen display along with the direction in which the user holds the terminal during the use of the terminal. In some embodiments of the present application, a boundary coordinate corresponding to the preloaded active window stack is (H, 0, 2H, H), a coordinate system corresponding to the boundary coordinate is a system coordinate, an origin of the system coordinate is an upper left corner of the display screen, and H is a length of a long side of a display area of the display screen. That is, the side corresponding to H is the maximum side of the display area of the display screen, and is the height of the display screen in the vertical screen display and the width of the display screen in the horizontal screen display. This is done to allow for the display of a landscape screen, pre-loaded application landscape displays, and the normal display of some applications. Fig. 2 is a schematic diagram illustrating a relative position relationship between a preloaded active window stack and a display area of a display screen according to an embodiment of the present disclosure. As shown in fig. 2, at this time, the display screen is in a vertical screen mode, the origin of the terminal system coordinates is the left vertex (0,0) of the display screen 201, the width direction of the display screen 201 is the X axis, the height direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack202 are (H, 0, 2H, H), H is the screen height, that is, the area in the left solid line rectangular range is the main screen display area, and the area in the right dotted line rectangular range is the preloaded display area. Fig. 3 is a schematic diagram illustrating a relative position relationship between a preloaded active window stack and a display area of a display screen according to an embodiment of the present application. As shown in fig. 3, at this time, the display screen is in a landscape mode, the origin of the terminal system coordinates is the left vertex (0,0) of the display screen 301, the height direction of the display screen 301 is the X axis, the width direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack202 are (H, 0, 2H, H), H is the screen height, that is, the area in the left solid line rectangular range is the main screen display area, and the area in the right dotted line rectangular range is the preloaded display area.
The reason why the pre-loaded Stack boundaries are so set is that:
the abscissa of the upper left corner is H, which is an interface for preventing the display screen (also referred to as a main screen) from displaying the preloaded application during the landscape screen, and since the main screen has a landscape mode in addition to the portrait mode, the abscissa of the upper left corner of the rectangular area corresponding to the preloaded Stack is set to the screen height in order to prevent the main screen display area from displaying the local part of the preloaded application during the landscape screen of the main screen.
The ordinate in the upper left corner is 0 in order for the preload application to be able to calculate the status bar height correctly. In order to better design a User Interface (UI), the Android application can customize the top status bar, and if the vertical coordinate corresponding to the upper edge is not equal to 0, the height of the status bar may be wrong.
The abscissa of the lower right corner is 2H (2 times the screen height), that is, the width of the rectangle corresponding to the preloaded Stack is equal to the screen height, so that the size of the preloaded Stack can contain the landscape application at the time of preloading (that is, the application interface is an application program in a landscape display mode).
The ordinate of the lower right corner is H, i.e. the height of the rectangle corresponding to the preloaded Stack is equal to the screen height, so as to preload the size of the Stack and be able to contain the vertical screen application at the time of preloading.
For the reasons described above, the inventors set the size of the preload Stack to (H, 0, 2H, H).
In addition, fig. 4 is a schematic application interface migration diagram provided in the embodiment of the present application, as shown in fig. 4, when an operation instruction of a target application program is received, an application interface 401 corresponding to the target application program included in a preloaded active window Stack is migrated to a display screen 201 to be displayed, specifically, a task to which the preloaded application interface belongs is migrated to the top of an application active window Stack, and size information, configuration information, and visibility of the task are updated, so that the application interface can be normally displayed on the display screen.
Fig. 5 is a flowchart of another management method for preloaded applications according to an embodiment of the present application, where the method includes:
And step 505, closing the first application program corresponding to the preloading completion time.
For example, if the time difference between the preload completion time and the current system time exceeds a preset time threshold, the first application program corresponding to the preload completion time is closed.
And step 507, creating a target process corresponding to the second application program, and initializing the target process.
And step 508, creating a task stack corresponding to the second application program in the preloading active window stack.
It should be noted that the second application program updates its own focus flag according to the fake focus notification, and continuously draws and updates the application interface corresponding to the second application program based on the activated active window within a preset time period.
It should be noted that steps 506 to 509 are also steps executed when the application preloading event is triggered, and the steps related to closing the first application program in steps 502 to 505 may be interchanged or executed in parallel, and the embodiment of the present application is not limited thereto.
And step 510, when the execution of the preloading operation corresponding to the application preloading event is completed, performing descending order arrangement on the second application programs and the remaining first application programs according to the starting prediction probability and the preloading completion time, and closing the application programs with the set number after the order arrangement.
Specifically, taking an application active window as an App Stack as an example, moving the task to the App Stack may include: this task is removed from the list in the original Stack (i.e., the preloaded Stack) and added at the top in the new Stack (app Stack). Each stack has a list for recording all the tasks contained in the stack; correspondingly, each task will record the stack information of the task at the same time. Since a stack contains attributes such as size, configuration, visibility, and zorder, which may be different from other stacks, the attributes such as zorder of the task may be changed simply by adding the task to the list of the new stack. The top added in the new stack is to make the task visible.
And step 512, updating the size information, the configuration information and the visibility of the task stack to display the current application interface corresponding to the target application program on a display screen.
It will be appreciated that the last application interface when the preloading is complete can be migrated to the display screen for display.
Specifically, the updating of the size information and the configuration information of the task stack is to change the boundary of the application, and may specifically include: actively updating the size and configuration information. The size and configuration of the task cannot be changed immediately only by using the above task migration operation, so that the method for modifying the size and configuration of the task can be actively called, the application state is ensured to be correct, and the application can normally work in the foreground.
Specifically, the update task is visible because, after the size and configuration are updated, the target application may not be visible at this time, a method of updating the visibility of the new stack is invoked, the visible applications are searched from top to bottom, set to visible, and the corresponding window surface is updated to visible. The visible application judgment method may include: is not occluded by other applications on the zorder; is not shielded by the lock screen; the state of the top activity of the application is a non-initializing or non-exiting state.
According to the management method for the preloaded application, after the application program is preloaded, the progress of a part of the preloaded application program can be ended according to the preloading completion time, and the phenomenon that the application program occupies memory resources for a long time is avoided; in addition, after the execution of the preloading operation corresponding to the application preloading event is completed, the starting prediction probability and the preloading completion time are comprehensively considered to finish the process of the preloaded application program meeting the conditions, so that the processing speed of the intelligent terminal is improved. In addition, all the preloaded application programs are not closed at one time, the problem that a user needs to use the preloaded application programs and needs to reload the application programs is avoided, and therefore the starting speed is effectively improved.
