Detailed ways

The technical solutions of the present application will be further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all the structures related to the present application.

Before discussing the exemplary embodiments in greater detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart depicts the steps as a sequential process, many of the steps may be performed in parallel, concurrently, or concurrently. Furthermore, the order of the steps can be rearranged. The process may be terminated when its operation is complete, but may also have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

1 is a schematic flowchart of an application preloading method provided by an embodiment of the present application. The method may be executed by an application preloading apparatus, where the apparatus may be implemented by software and/or hardware, and may generally be integrated in a terminal. As shown in Figure 1, the method includes:

Step 101. It is detected that an application preloading event is triggered.

Exemplarily, the terminals in the embodiments of the present application may include terminal devices such as mobile phones, tablet computers, notebook computers, and smart home appliances. An operating system is loaded into the terminal.

Exemplarily, the triggering condition of the application preloading event may be set according to the actual situation, which is not specifically limited in this embodiment of the present application. For example, an application preloading event can be triggered when it is detected that the user's action meets a preset condition (such as picking up the terminal, inputting a screen unlocking operation, or inputting a terminal unlocking operation, etc.); or when it is detected that the foreground application has changed, The application preloading event is triggered; or the application preloading event can be triggered immediately (or after a preset duration) after the prediction process of preloading the application ends; or the application preloading event can be triggered at regular intervals, and so on. After the application preloading event is triggered, the system can detect that the application preloading event has been triggered by reading a flag bit or receiving a trigger instruction, and the specific detection method is not limited in the embodiment of the present application.

Step 102: Determine the application to be preloaded.

Exemplarily, the application to be preloaded may be understood as an application that the user may be about to open, which may be a preset fixed application, or an application predicted in a certain manner, or the like. The application to be preloaded may include one or more.

In order to improve the startup speed of applications, on terminal devices, preloading applications is a common and effective method to improve user experience. It predicts the applications that users may be using, and prepares the startup resources of these applications in advance. Well, so that it can start quickly when it is actually opened by the user. In the related art, applications are preloaded mainly based on statistical methods. For example, there may be only a few applications that are most commonly used by the user, and all these applications are preloaded. However, the above method is too simple and rude, resulting in insufficient prediction accuracy and accuracy of the preloaded application. Therefore, in order to improve the prediction accuracy, in this embodiment of the present application, a prediction model may be used to predict the application to be preloaded. The prediction model may be a machine learning model, and the algorithms used may include Recurrent Neural Networks (RNN), Long Short-Term Memory (LSTM) networks, Threshold Recurrent Units, Simple Recurrent Units, Auto-encoding algorithm, decision tree, random forest, feature mean classification, classification regression tree, hidden Markov, K-Nearest Neighbor (KNN) algorithm, logistic regression model, Bayesian model, Gaussian model and KL divergence (Kullback – Leibler divergence) and so on.

Optionally, in the process of using the terminal, the user may collect training samples, use the training samples to train the preset initial model, and finally obtain a prediction model for predicting the application to be preloaded. Exemplarily, the elements contained in the training samples may include the time sequence or sequence sequence when the application is opened; may include the time, location, and frequency when the application is opened; may include the running state of the terminal, such as the switch of the mobile data network. Status, the connection status of the wireless hotspot, the identity information of the connected wireless hotspot, the currently running application, the last foreground application, the duration of the current application staying in the background, the last time the current application was switched to the background, The plug-in status, charging status, battery power information, and screen display time of the headphone jack, etc.; it can also include data collected by sensors integrated in the terminal, such as motion sensors, light sensors, temperature sensors, and humidity sensors.

Exemplarily, appropriate sample elements can be selected according to the selected machine learning model, or the selected machine learning model can be determined according to the selected sample elements, and can also be carried out in combination with the requirements for prediction accuracy and preset speed. Selection of models and sample elements, etc., are not limited in the embodiments of the present application.

In this embodiment of the present application, determining the application program to be preloaded may include determining the application program to be preloaded according to the previous output result of the prediction model, or may include using the prediction model to make predictions, and determining the current output result of the prediction model to determine the application program to be preloaded .

In this embodiment of the present application, when there are multiple (N) applications to be preloaded, the prediction model may output the activation probability of each candidate application set in the candidate application set, and determine the candidate application with a higher activation probability as the to-be-preloaded application. Preload the application. Optionally, the determining of the application to be preloaded includes: predicting the activation probability of the candidate application; and determining a preset number of candidate applications with a higher activation probability as the application to be preloaded. Exemplarily, the candidate applications may include all applications installed in the terminal, and may also include some applications. Some applications may not include system applications or applications that are rarely used by users. The embodiments of the present application do not limit the manner and quantity of candidate application programs. Optionally, candidate applications can be determined according to the number of times of use and/or the duration of use of each application within a preset period before the current moment. The preset period is, for example, one month. When the threshold is reached, the corresponding application is determined as a candidate application, or the applications are sorted according to the number of times of use and/or the duration of use, and the top ranked application is determined as a candidate application.

Exemplarily, the prediction model described above can be used to determine the activation probability of each candidate application. For example, the current sample is collected according to the training sample during the training of the prediction model, and the current sample is input into the prediction model to obtain the startup probability of each candidate application program. The startup probability can be sorted from high to low, and the candidate application programs in the top N (N is a preset value) are determined as the application programs to be loaded. The advantage of this setting is that multiple applications can be preloaded, and the multiple applications are determined according to the startup probability, which can improve the accuracy of prediction.

Step 103: Preload the application to be preloaded, and during the preloading process, prohibit preloading the preset application interface in the application to be preloaded.

In the embodiment of the present application, when there is only one application to be preloaded, the preloading sequence of the applications does not need to be considered; and when there are multiple applications to be preloaded, the multiple applications to be preloaded can be determined one by one as the current application Applications to be preloaded and preloaded in sequence, or more than two applications to be preloaded may be determined as the current applications to be preloaded, and preloaded simultaneously, that is, the preloading of multiple applications. The loading process can be performed in parallel.

The specific process of preloading and the loaded resources are not limited in the embodiments of the present application. For example, corresponding hardware resources may be allocated to the application to be preloaded, and relevant data required for startup may be loaded based on the allocated hardware resources. Exemplarily, it may include application process startup, application service startup, memory allocation, file content reading, network data acquisition, and interface rendering (ie, preloading the application interface), and the like. In addition, the preloaded resources can also be determined according to the specific type of the application to be preloaded. In order to improve the completion degree of preloading, in this embodiment of the present application, the application interface of the application to be preloaded is preloaded. However, not all application interfaces involved in the preloading process are required by the user, and generally preloading is performed when the user is invisible. If all application interfaces are preloaded, it will waste more time. A large number of system resources, such as a central processing unit (Central Process Unit, CPU) or a graphics processing unit (Graphics Processing Unit, GPU) and other resources, not only increases the system power consumption, but also affects the preloading speed. In this embodiment of the present application, part of the application interface that does not need to be preloaded may be pre-determined. During the preloading process, when it is detected that the application interface currently requiring preloading belongs to this type of application interface, preloading the application interface is prohibited. .

In the application preloading method provided in the embodiment of the present application, after detecting that an application preloading event is triggered, the application to be preloaded is determined, the application to be preloaded is preloaded, and during the preloading process, the application to be preloaded is prohibited. Load the preset application interface in the application for preloading. By adopting the above technical solution, in the process of preloading the application program, the application interface can be selectively preloaded, that is, the preloading operation of some pre-set application interfaces can be omitted, which can improve the preloading efficiency and save money. system resources and reduce power consumption.

In some embodiments, preloading the application to be preloaded includes: displaying an application interface corresponding to the application to be preloaded based on a pre-created stack of preloaded active windows, wherein the preloaded active window The bounding coordinates corresponding to the stack are outside the coordinate range of the display screen. Preloading is performed off-screen, and the preloading process is invisible to the user and will not affect the display of the display content of the foreground application on the display screen.

In this embodiment of the present application, the active window may be understood as an independent interface that directly provides interaction and operation to the user, and different nouns may be used to name the interface in different operating systems. For ease of understanding, the following description is made by 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 the user, which provides a screen (which can be understood as a screen interface, rather than an entity display screen) for the user to interact to complete a certain task. In an android application, an Activity is usually a separate screen, which can display some controls and listen to and handle user events. In the management of Activity, there are two concepts: Task (task stack) and Stack (active window stack). Task corresponds to an application, Task is used to store Activity, and a Task can store one or more Activities, and these Activities follow the principle of "first in, last out, last in first out". The Stack is also used to manage the Task. Usually, a Stack manages the Task to which each Activity needs to be displayed on a screen. A Stack can manage one or more Tasks. Of course, the Stack also follows the basic management principles of the stack. . The screens described here are not necessarily complete and independent display screens. Taking "two screens" as an example, the two screens may be just two areas in a complete display screen that independently display their respective display contents. Of course, if the terminal has two or even more than two independent display screens, the "two screens" may also be two independent display screens.

In the Android system, multi-window modes are supported, including split-screen mode, picture-in-picture mode, and FreeForm. In multi-window mode, the stack where the application is located can have its own size (size), which can include up, down, left, and right coordinates in the coordinate system with the upper left corner of the terminal screen as the origin. For example, (a, b, c, d) generally describes the boundary of a rectangle, which can be represented by the coordinates of the upper left corner and the lower right corner of the rectangle, that is, the coordinates of the upper left corner of the rectangle are (a, b), the right The coordinates of the lower corner are (c, d), and such a rectangular area corresponds to the size of the Stack. The in-app layout in the Stack is based on the size of the Stack, which means that the application interface corresponding to the Activity is displayed within the bounds of the size.

In multi-window mode, multiple applications can be allowed to be visible, both system and user visible and system-only. Visible to both the system and the user means that it is displayed on the display screen and can be seen by the user; only visible to the system means that the operating system is visible, but the user is invisible, and may be blocked by the application in the foreground or as the application intends to achieve. Display off-screen display.

In the embodiment of the present application, preloading the application interface of the application to be preloaded outside the display screen can be realized based on the multi-window mechanism of the operating system, and the size corresponding to the application program is set outside the display screen through the multi-window mechanism. The purpose is invisible to the user, so that it will not affect the display of the display content of the foreground application on the display screen.

Generally, in the multi-window mode, there can be multiple types of Stacks, such as Home Stack, which represents the Stack displayed by desktop applications, App Stack, which represents the display of third-party applications, and other split-screen Stacks. In the embodiment of the present application, a preloaded active window stack (preloaded Stack) is newly added, which is used to represent the stack displayed by the preloaded application, and the boundary coordinates of the preloaded stack are set outside the coordinate range of the display screen, and the preloaded stack is to be preloaded. applications can be displayed in this stack. For the Android system, based on the multi-window mechanism of the Android system, a new Stack dedicated to displaying preloaded applications can be created. In the embodiment of the present application, the reason for creating a new stack is that the newly created preloaded stack can have its own size and visibility, so as to achieve the purpose of preloading outside the display screen.

In the embodiment of the present application, the creation timing of the preloaded stack is not limited. It can be that the preloaded stack is set to be in a resident state by default before the terminal leaves the factory, that is, the preloaded stack always exists; it can also be when the terminal is powered on or the terminal is successfully unlocked. Created after; it can also be created after the application preload event is triggered (it can be before the application to be preloaded is determined), and so on. Optionally, preloading the application interface corresponding to the application to be preloaded based on the pre-created preloading active window stack includes: judging whether there is a pre-created preloading active window stack; A rule is set to create a preloaded active window stack; based on the created preloaded active window stack, an application interface corresponding to the application to be preloaded is preloaded. The advantage of this setting is that after determining the application to be preloaded to be preloaded, it is determined whether the preloaded stack exists. If it exists, there is no need to create a new one. It is understandable that when there are multiple applications to be preloaded, that is, when multiple applications need to be preloaded continuously in a short period of time, before the first application to be preloaded starts to load, the preload stack has been created. After that, before the second application to be preloaded starts to load, the preload stack exists, and the above judgment is not necessary.

In this embodiment of the present application, the specific process of preloading the application interface corresponding to the application to be preloaded based on the preloading Stack is not limited, for example, the application interface may be drawn and displayed based on the size of the preloaded Stack.

In some embodiments, the preloading the application interface corresponding to the application to be preloaded based on the pre-created preloading active window stack includes: creating a target process corresponding to the application to be preloaded; Create a task stack corresponding to the application to be preloaded in the preloading active window stack; start the active window corresponding to the application to be preloaded in the task stack based on the target process; draw based on the activated active window and displaying the application interface corresponding to the application to be preloaded. The advantage of this setting is that the application interface of the application to be preloaded can be drawn and displayed based on the stack of preloaded active windows outside the range of screen coordinates, without interfering with the running and display of the foreground application, ensuring system stability, and at the same time effectively Improves the speed at which the application to be preloaded starts. When the target process is created, the initialization process of the target process can also be included. During the execution of the above steps, preloading of other resources may also be involved, such as application service startup, memory allocation, file content reading, and network data acquisition, etc. The embodiment of the present application does not limit the preloading process of other resources.

In some embodiments, the method further includes: sending a fake focus notification to the application to be preloaded, and maintaining continuous drawing of an application interface corresponding to the application to be preloaded for a preset period of time based on the fake focus notification and display updates. The advantage of this setting is that the drawing and display of the application interface can be completed when the application to be preloaded has the focus and is visible to the system, improving the completion of the preloading without affecting the focus of the foreground application. The focus in this embodiment of the present application is also called the input focus, and the fake focus and the focus corresponding to the foreground application are independent of each other. In general, for the current Android system, the focus is unique. For example, input operations such as touch only take effect on the focus. For input focus information, the system side and the application side are consistent. Once the system side modifies the input focus information, it will Send the information that the input focus information changes to the application, in this way, ensure that the input focus information on the system side and the application side are consistent. In this embodiment of the present application, by separating the input of focus information at the system end and the application end, the purpose of forging the focus at the application end is achieved. Specifically, in this embodiment of the present application, the preloaded application is forged a focus notification, so that the preloaded application has focus information, while the focus information on the system side is still correct. This processing can enable the preloaded application to draw normally and achieve full loading. Purpose. The focus exists on the system side and the application side, which can be considered as the server (server) and the client (client). The timing for faking the input focus can be when a new window is added to the Android window system and the focus needs to be updated, a fake focus notification is generated and sent. The method of forging the focus may be to call the method of changing the focus of the window on the client side of the window, so that the window obtains the focus. Specifically, the forged focus notification can be sent based on the Binder mechanism. The Binder mechanism is the most common way of inter-process communication in the Android system, and adopts the c/s architecture, that is, the client/service architecture. In this embodiment of the present application, the preset time period may be designed according to the actual situation, for example, it may be within a fixed period of time after starting preloading, or may be a period from starting preloading to completing preloading, or the like.

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 usually include vertical screen display and horizontal screen display. Many applications are displayed in vertical screen mode by default, while some By default, applications are displayed in a horizontal screen mode (such as some online games). During the use of the terminal, some applications will also switch between horizontal and vertical screen display according to the direction in which the user holds the terminal. In some embodiments of the present application, the boundary coordinates corresponding to the preloaded active window stack are (H, 0, 2H, H), the coordinate system corresponding to the boundary coordinates is system coordinates, and the origin of the system coordinates is In the upper left corner of the display screen, H is the length of the long side of the display area of the display screen. That is to say, the side corresponding to H is the largest side of the display area of the display screen, which is the height of the display screen when it is displayed in a vertical screen, and the width of the display screen when it is displayed in a horizontal screen. The purpose of this setting is to take into account the horizontal display of the display screen, the horizontal display of preloaded applications, and the normal display of some applications. FIG. 2 is a schematic diagram of a relative positional 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. 2, the display screen is in a vertical screen mode at this time, 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, and the height direction is the Y axis. The boundary coordinates corresponding to the loading Stack202 are (H, 0, 2H, H), where H is the height of the screen, that is, the area within the rectangle with the solid line on the left is the main screen display area, and the area within the rectangle with the dotted line on the right is the preload display area. FIG. 3 is a schematic diagram of a relative positional relationship between another 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 , the display screen is in a landscape mode at this time, 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, and the preset The boundary coordinates corresponding to the loading Stack202 are (H, 0, 2H, H), where H is the height of the screen, that is, the area within the rectangle with the solid line on the left is the main screen display area, and the area within the rectangle with the dotted line on the right is the preload display area.

The reason why the boundaries of the preload stack are set like this is that:

The abscissa of the upper left corner is H, which is to prevent the display screen (also called the main screen) from being displayed to the interface of the preloaded application when the screen is horizontal, because the main screen has a horizontal screen mode in addition to the vertical screen mode. When the main screen is horizontal screen , in order to prevent the display area of the main screen from displaying a part of the preloaded application, the abscissa of the upper left corner of the rectangular area corresponding to the preloaded Stack is set as the screen height.

The vertical coordinate of the upper left corner is 0, so that the preloaded application can correctly calculate the height of the status bar. In order to better design the user interface (UI), the Android application will customize the top status bar. If the ordinate corresponding to the top 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 = the height of the screen, so that the size of the preloaded Stack can include the horizontal screen application during preloading (that is, the application interface is horizontal screen). display mode application).

The vertical coordinate of the lower right corner is H, that is, the height of the rectangle corresponding to the preloaded Stack = the height of the screen, so that the size of the preloaded Stack can include the vertical screen application during preloading.

Based on the above reasons, the inventors set the size of the preloaded Stack to (H, 0, 2H, H).

In some embodiments, the preset application interface includes a startup page interface and/or a preset switching animation interface.

Among them, the startup page is also called the splash screen (Splash screen), the enlightenment window (Starting window) or the preview window (Preview Window), etc., generally refers to the first page to open the application, initially for the application to be able to open quickly, to prevent When a white or black screen appears, the main page can be loaded in the background while the startup page is displayed. Now the startup page is often used to display information such as the branding, event promotion, and advertisement of the application. The startup page in the embodiment of the present application may be a static page or a dynamic page, wherein the dynamic page may include an animation page or a page that is continuously dynamically switched, which is not specifically limited in the embodiment of the present application. When opening an Activity, if the application to which the Activity belongs is not running, the system will create a process for the application to which the Activity belongs, but the creation and initialization of the process take time, and if the system does not respond before this action is completed If it is, the user may think that the corresponding position is not clicked, so the startup page appears to solve this problem. The startup page can be understood as a temporary window displayed before the application process is created and initialized successfully. This window is displayed before the program initialization is completed to inform the user that the system has known that he wants to open the application and responded. When the program initialization is completed, a user-operable human-computer interaction interface (such as the main page of the application program) is displayed, and the startup page window is removed.

In some embodiments, when the preset application interface includes a startup page interface, the preloading of the preset application interface in the application to be preloaded is prohibited during the preloading process, including: : During the preloading process, when it is detected that the startup page interface display function in the active window management service is about to be called, the startup page interface display function is prohibited from being called. The advantage of this setting is that the display of the startup page interface can be quickly and accurately prohibited. Taking the Android system as an example, there is a special function startup page interface display function (showStartingWindow) in the activity management service (ActivityManagerService) of the application program to process and display the startup page. Generally, when or after the process of the application program is created, the interface display function of the startup page is called to avoid the occurrence of white screen or black screen. Therefore, it can be detected when the process of the application to be preloaded starts to be created. , it is considered that it is detected that the startup page interface display function in the active window management service is about to be called, and the invocation of the startup page interface display function is prohibited at this time.

When the preset application interface includes a startup page interface, during the preloading process, prohibiting preloading the preset application interface in the application to be preloaded may also include: in the preloading process During the preloading process, when calling the startup page interface display function in the active window management service, the startup page interface display function is used to determine whether the current startup page interface belongs to the application to be preloaded; if so, the display of the current startup page interface is prohibited. Start page interface. The advantage of this setting is that it can accurately determine whether the startup page interface to be displayed belongs to the application program to be preloaded, and when it is determined that it belongs to the application program to be preloaded, the display of the startup page interface is stopped in time. In this embodiment of the present application, the calling steps of the startup page interface display function can be retained to ensure the stability of application preloading, and the function can be improved by adding judgment logic to the function, so that the current needs can be judged in the function. Whether the displayed startup page interface belongs to the application to be preloaded, and if so, the startup page interface will not be displayed, so as to prohibit preloading of the startup page interface of the application to be preloaded.

In some embodiments, determining whether the current startup page interface belongs to the application to be preloaded by the startup page interface display function includes: identifying the current startup page interface according to the window type by the startup page interface display function; The startup page interface display function determines whether the current startup page interface belongs to the application to be preloaded. The advantage of this setting is that the startup page interface can be accurately identified. Taking the Android system as an example, the window type (Window Type) owned by the startup page is TYPE_APPLICATION_STARTING, which is the unique flag (flag) of the startup page. The showStartingWindow function can accurately identify the startup page according to the flag, and judge whether the startup page interface belongs to the waiting page. Preload the application, if it belongs, the splash page interface will not be displayed. Exemplarily, it can be determined whether the application to which the startup page interface belongs is the application to be preloaded. Specifically, the identity identifier of the active window stack where the application to which the startup page interface belongs can be obtained, and it is determined whether the identity identifier is a preloading identity; if so, it is determined that the application is a preloading application. The advantage of this setting is that it can quickly and accurately determine whether the application to which the startup page interface belongs is a preloaded application according to the stack's identity.

In some embodiments, the preset application interface includes a preset switching animation interface. The system will generate animations when an application is opened or switched between active windows, and animation drawing consumes a lot of resources such as CPU/GPU.

Exemplarily, when the preset application interface includes a preset switching animation interface, during the preloading process, preloading the preset application interface in the application to be preloaded is prohibited, including: : During the preloading process, when it is detected that the preparatory application switching function in the window management service is about to be called, the preparatory application switching function is prohibited from being called. The advantage of this setting is that the preloading of the preset application interface can be quickly and accurately prohibited. The preset switching animation interface may include an Activity switching animation interface. Taking Android as an example, typical Activity switching animations may include: activityOpenEnterAnimation, activityOpenExitAnimation, taskOpenEnterAnimation, taskCloseExitAnimation, wallpaperOpenEnterAnimation, and wallpaperCloseEnterAnimation. The system sets the opening and switching animations by calling the prepareAppTransition function of WindowManagerService. For example, the first step of Activity switching animation setting is to set the Activity switching animation type by calling the prepareAppTransition function. Currently, the more common types include TRANSIT_ACTIVITY_OPEN, TRANSIT_ACTIVITY_CLOSE, TRANSIT_TASK_OPEN, TRANSIT_TASK_CLOSE, TRANSIT_TASK_TO_FRONT, TRANSIT_TASK_TO_BACK. The prepareAppTransition() function mainly does two things: the first is to set the animation type to AppTransition, which will be used in subsequent operations; the second is to send a 5s timeout message of APP_TRANSITION_TIMEOUT. When it is detected that the system starts to set the Activity switching animation, it can be considered that the preparatory application switching function in the window management service is about to be called. At this time, the invocation of the preparatory application switching function is prohibited, thus ending the Activity switching animation from the first step. The setting process, thus realizing the prohibition of preloading operations such as subsequent drawing and display of the preset switching animation interface.

Exemplarily, when the preset application interface includes a preset switching animation interface, during the preloading process, preloading the preset application interface in the application to be preloaded is prohibited, and also It may include: during the preloading process, when calling the preliminary application switching function in the window management service, judging whether the current application is the application to be preloaded; if so, terminating the current application switching function of the preliminary application switching function Called to disable preloading of the preset switching animation interface in the current application. The advantage of this setting is that it can be accurately determined whether the current application is an application to be preloaded, and if so, the preloading of the preset switching animation interface of the current application is prohibited in time by terminating the function call. In the embodiment of the present application, the calling steps of the pre-application switching function can be retained to ensure the stability of application preloading, and when preparingAppTransition is called, a judgment logic is added to judge whether the current application is the application to be preloaded (that is, the current application is currently preloaded). Whether the application has started preloading), to decide whether to continue the calling operation of the prepareAppTransition function, if so, terminate the function call, so as to prohibit animation during preloading, which can speed up the drawing speed, reduce power consumption, and avoid background animation. The animation abnormal problem caused by the foreground animation.

The application interface corresponding to the target application may include an application interface corresponding to the active window currently at the top of the stack in the task stack corresponding to the target application. The advantage of this setting is that the target application can be quickly launched by directly migrating the preloaded application interface to the display screen for display, while the startup page and the preset switching animation are not preloaded and migrated to The application interface of the display screen is an interactive interface that the user can directly operate, and the user can operate the target application program without waiting, which can improve the running efficiency of the target application program.

Exemplarily, FIG. 4 is a schematic diagram of application interface migration provided by an embodiment of the present application. As shown in FIG. 4 , when receiving a running instruction of a target application, the target application included in the preloaded active window stack is corresponding to the target application. The application interface 401 is migrated to the display screen 201 for display. Specifically, the task to which the preloaded application interface belongs is migrated to the top of the application activity window Stack, and the size information, configuration information and visibility of the task are updated, so that the application interface can be Displays normally on the display screen.

FIG. 5 is a schematic flowchart of another application preloading method provided by an embodiment of the present application. Taking the Android operating system as an example, the method includes the following steps:

Step 501 , when it is detected that an application preloading event is triggered, determine the application to be preloaded.

Step 502: Start to preload the application to be preloaded.

Call the prepareAppTransition function in WindowManagerService.

It can be understood that step 506 may involve the drawing and update display of multiple application interfaces. When it is found that the prepareAppTransition function is about to be called, the calling is prohibited, so as to prohibit the drawing of the preset switching animation interface in the application to be preloaded and show.

Step 507: When receiving the running instruction of the target application in the applications to be preloaded, migrate the application interface corresponding to the target application included in the preloaded active window stack to the display screen for display.

In the application preloading method provided by the embodiment of the present application, in the process of preloading the application to be preloaded, the display of the startup page interface is prohibited by prohibiting the invocation of the showStartingWindow function, and the preset switching is prohibited by prohibiting the invocation of the prepareAppTransition function The preloading of the animation interface can quickly and accurately prohibit these application interfaces from being preloaded during the preloading process, speed up the drawing speed of the preloading interface, improve the preloading efficiency, and reduce the power consumption of the preloading operation.
