Detailed Description

The technical scheme of the application is further explained by the specific implementation mode in combination with the attached drawings. 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 illustrating an application prompting method according to an embodiment of the present application, where the method may be executed by an application prompting device, where the device may be implemented by software and/or hardware, and may be generally integrated in a terminal. As shown in fig. 1, the method includes:

step 101, when detecting that the switching frequency of the foreground application program is higher than a preset frequency threshold, triggering an application preloading event.

For example, the terminal in the embodiment of the present application may include terminal devices such as a mobile phone, a tablet computer, a notebook computer, and an intelligent appliance. The terminal is loaded with an operating system.

Illustratively, the switching frequency may represent, for example, the number of times the user switches the foreground application within a unit time (e.g., 1 minute). The preset frequency threshold may be set according to the definition of the switching frequency, and as mentioned in the foregoing example, the preset frequency threshold may be 3 times/minute. When the switching frequency is high, it indicates that the user frequently switches among a plurality of application programs in a short time, the user may not know what the user wants to do, and the application programs opened by the user are not used for a long time, so that the application preloading event can be triggered at this time to help the user to select according to the preloading result.

And step 102, determining an 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 application to be preloaded may include determining the application to be preloaded according to an output result before the prediction model, or may include predicting by using the prediction model and determining the application to be preloaded according to a current output result of the prediction model.

And 103, preloading the application program to be preloaded.

In the embodiment of the application, when only one application program is to be preloaded, the preloading sequence of the application is not required to be considered; when there are multiple application programs to be preloaded, the multiple application programs to be preloaded can be determined one by one as the current application program to be preloaded, and the preloading operation is performed sequentially, or more than 2 application programs to be preloaded can be determined as the current application program to be preloaded, and the preloading operation is performed simultaneously, that is, the preloading processes of the multiple application programs can be performed in parallel.

In the embodiment of the present application, the specific process of preloading and the loaded resources are not limited, for example, corresponding hardware resources may be allocated to the application program to be preloaded, and relevant data required for starting is loaded based on the allocated hardware resources. The method comprises the following steps of starting an application process, starting an application service, allocating memory, reading file content, acquiring network data, rendering an interface and the like. Furthermore, the resources to be preloaded may be determined according to the specific type of application to be preloaded. For example, if the application to be preloaded is a social software, a start screen, a contact list, a recent message record, and the like in the application may be preloaded; if the application program to be preloaded is a game, the game background related data in the application program can be preloaded.

And 104, prompting a user for the preloaded application program which is preloaded.

In the embodiment of the present application, the preloaded applications that have been preloaded may include applications that are being preloaded, and may also include applications that have already been preloaded.

The specific prompting mode is not limited in the embodiment of the application. For example, the manner of prompting the user may be a graphical prompt, a text prompt, a voice prompt, or the like. Alternatively, the preloaded application may be displayed in the form of a floating window, a pop-up window, a fixed display area, or the like in the display screen, and a name or an icon of the preloaded application may be displayed, or the like. When there are multiple preloaded applications, the application programs may be presented one by one in a certain order, or more than 2 of the application programs may be selected for bulk presentation (that is, the number of preloaded application programs presented each time is greater than or equal to 2).

When the application program is preloaded, certain system resources are consumed or occupied, and especially after the preloading is completed, if the application program is not really started by a user, certain resource waste is caused. In some scenes, a user may not know what the user wants to do with the terminal, or something that needs to be done is not thought by the user, so the user may not have a strong intention to start a certain application program.

According to the application program prompting method provided by the embodiment of the application program, when the switching frequency of the foreground application program is detected to be higher than the preset frequency threshold value, the application preloading event is triggered, the application program to be preloaded is determined, the application program to be preloaded is preloaded, and a user is prompted according to the preloaded application program. By adopting the technical scheme, when the switching frequency of the foreground application is high, the application preloading event can be triggered, the determined application to be preloaded is preloaded, the user is effectively prompted according to the preloaded application program which is preloaded, the user is helped to select the application, and meanwhile, the utilization rate of the preloaded resource is improved.

In some embodiments, the number of the applications to be preloaded is a preset number, and the preset number is greater than or equal to 2. The determining the application program to be preloaded comprises the following steps: predicting a launch probability of a candidate application; and determining the candidate application programs with the higher starting probability as the application programs to be preloaded. Illustratively, the candidate applications may include all applications installed in the terminal, and may also include part of the applications. Some applications may not include system applications or applications that are rarely used by the user. The determination mode and the number of the candidate application programs are not limited in the embodiment of the application. Optionally, the candidate application program may be determined according to the number of times of use and/or the use duration of each application program in a preset time period before the current time, where the preset time period is, for example, 1 month, and when the number of times of use and/or the use duration exceed a corresponding threshold, the corresponding application program is determined as the candidate application program, or the application programs are sorted according to the number of times of use and/or the use duration, and the application program with the highest ranking is determined as the candidate application program.

For example, the predictive model described above may be employed to determine the launch probability of each candidate application. For example, according to a training sample during the training of the prediction model, a current sample is collected and input into the prediction model, so as to obtain the starting probability of each candidate application program. The starting probabilities may be sorted from high to low, and the top N candidate applications (N is a preset value) may be determined as the applications to be loaded. The method has the advantages that the application programs can be pre-loaded, the application programs are determined according to the starting probability, the prediction accuracy can be improved, and the application programs more suitable for the current requirements of the user can be prompted to the user after the application programs are pre-loaded.

In some embodiments, preloading the application to be preloaded includes: and preloading the application programs to be preloaded according to the sequence from high starting probability to low starting probability corresponding to the application programs to be preloaded. The method has the advantages that the starting probability is high, the application program is more likely to be selected by the user, and in order to accelerate the speed when the application program to be preloaded with high starting probability is selected by the user and is actually started, the application program to be preloaded with high starting probability is preferentially preloaded, and the preloading completion degree is guaranteed as much as possible. For example, the application program to be preloaded with the highest starting probability may be preloaded, and after the application program to be loaded is preloaded, the next application program to be preloaded is preloaded; or, the application program to be preloaded with the highest starting probability may be preloaded, and when the application program to be loaded is to be preloaded, the next application program to be preloaded is preloaded. In addition, the sequential preloading can also provide more support for the application program currently being preloaded, for example, more hardware resources are allocated, the preloading speed is increased, adverse effects such as blocking and the like caused by parallel preloading can also be avoided, and the normal operation of the foreground application program is ensured.

In some embodiments, the prompting the user for the preloaded application that has been preloaded includes: and prompting the user for the preloaded application programs according to the sequence from high to low of the starting probability corresponding to the preloaded application programs for preloading. This has the advantage that preloaded applications with a high probability of being launched may be preferentially displayed as they are more likely to meet the user's needs. When a plurality of preloaded applications exist, the applications can be prompted one by one according to the sequence from high starting probability to low starting probability, or more than 2 of the applications can be selected for bulk prompting, and the preloaded applications with higher starting probability are arranged at the front position of a display queue during each bulk display.

In some embodiments, the prompting the user for the preloaded application includes: and displaying a starting inlet corresponding to the preloaded application program on a display screen. Correspondingly, after the starting entry corresponding to the preloaded application program is displayed on the display screen, the method further comprises the following steps: and determining a target starting inlet according to the selection operation of the user, and starting the target application program in the foreground based on the preloading resource of the target application program corresponding to the target starting inlet. The method has the advantages that the starting entrance can be displayed in the prompt area, and a user can conveniently and directly select the starting entrance, so that the corresponding preloaded application program can be quickly started. The launch portal may be, for example, an application icon or application name, etc.

In some embodiments, preloading the application to be preloaded includes: and preloading an application interface corresponding to the application program to be preloaded based on a pre-created preloading active window stack, wherein the boundary coordinate corresponding to the preloading active window stack is positioned outside the coordinate range of the display screen. The advantage of setting up like this is, to the application interface carry out the preloading, can accomplish the preparation before the application starts by great degree, promotes the boot-strap speed of preloading application program, and can not influence the demonstration of foreground application program's display content on 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, 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 of a desktop application display, App Stack represents a third-party application display, and there may be other split-screen stacks. 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 the application program to be preloaded based on a pre-created preload 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 preloaded Stack exists or not is judged, if yes, new construction is not needed, and if not, creation is conducted, 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.

In some embodiments, the preloading an application interface corresponding to the application program to be preloaded based on a pre-created preload active window stack includes: creating a target process corresponding to the application program to be preloaded; creating a task stack corresponding to the application program to be preloaded in a pre-created preloading active window stack; starting an active window corresponding to the application program to be preloaded in the task stack based on the target process; and drawing and displaying an application interface corresponding to the application program to be preloaded based on the started active window. The method has the advantages that the application interface of the application program to be preloaded can be drawn and displayed based on the preloading movable window stack outside the screen coordinate range, the running and the display of the foreground application program cannot be interfered, the system stability is guaranteed, and meanwhile the starting speed of the application program to be preloaded is effectively improved. 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 application program to be preloaded, and keeping continuous drawing and display updating of an application interface corresponding to the application program to be preloaded in a preset time period based on the fake focus notification. The method has the advantages that the application interface can be drawn and displayed under the condition that the application program to be preloaded obtains the focus and is visible to the system, the preloading completion degree is improved, and the focus of 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 application program to be preloaded is started, when the application program to be preloaded 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 application program to be preloaded is further advanced, and the waiting time is reduced.

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 some embodiments, when an execution instruction of a preloaded application program that has been preloaded (after the application program to be preloaded has been subjected to a preloading operation, the application program to be preloaded may be referred to as a preloaded application program) is received (for example, a user triggers a start-up entry corresponding to the preloaded application program), an application interface corresponding to the preloaded application program included in the preloaded active window stack is migrated to the display screen for display.
