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 of an application preloading method according to an embodiment of the present application, where the method may be performed by an application preloading 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, detecting that an application preloading event is triggered.
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.
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.
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 preset, or an application that is predicted in a certain manner, and the like. The application to be preloaded may comprise one or more.
In order to improve the starting speed of the application program, preloading of the application program is a common method for effectively improving user experience on the terminal device, the application program which is possibly about to be used by a user is predicted, and the starting resources of the applications are prepared in advance, so that the applications can be started quickly when the applications are really opened by the user. In the related art, the application programs are mainly preloaded based on a statistical method, for example, only a few application programs are most frequently used by a user, and all the application programs are preloaded. However, the above method is too simple and rough, which results in insufficient prediction precision and accuracy of the preloaded application program, and therefore, in order to improve the prediction accuracy, in the embodiment of the present application, the prediction model may be used to predict the application program 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.
In this embodiment of the application, when the number of the applications to be preloaded is multiple (N), the prediction model may output a start probability of each candidate application set in the candidate application sets, and determine the candidate application with a higher start probability as the application to be preloaded. Optionally, the determining the application to be preloaded includes: 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 advantage of this arrangement is that multiple applications can be preloaded, and the multiple applications are determined according to the launch probability, which can improve the accuracy of the prediction.
103, preloading the application program to be preloaded, and prohibiting preloading of a preset application interface in the application program to be preloaded in the preloading process.
In the embodiment of the application, when only one application program to be preloaded exists, the preloading sequence of the application is not required to be considered; when there are multiple applications to be preloaded, the multiple applications to be preloaded can be determined one by one as the current application to be preloaded, and the preloading operation is performed sequentially, or more than 2 applications to be preloaded can be determined as the current application to be preloaded and the preloading operation is performed simultaneously, that is, the preloading processes of the multiple applications 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 can exemplarily include application process starting, application service starting, memory allocation, file content reading, network data acquisition, interface rendering (namely preloading of an application interface), and the like. In addition, the preloaded resources may also be determined according to the specific type of application to be preloaded. In order to improve the completeness of the preloading, in the embodiment of the present application, an application interface of an application program to be preloaded is preloaded. However, the application interfaces involved in the preloading Process are not all needed by the user, and the preloading is generally performed under the condition that the user is not visible, and if all the application interfaces are preloaded, more system resources, such as a Central Processing Unit (CPU) or a Graphics Processing Unit (GPU), are wasted, which not only increases the system power consumption, but also affects the preloading speed. In the embodiment of the application, a part of the application interfaces which do not need to be preloaded can be determined in advance, and in the preloading process, when the application interfaces which currently need to be preloaded belong to the application interfaces, the application interfaces are prohibited from being preloaded.
According to the application program preloading method provided in the embodiment of the application program preloading method, after the application preloading event is triggered, the application program to be preloaded is determined, the application program to be preloaded is preloaded, and the preloading of a preset application interface in the application program to be preloaded is forbidden in the preloading process. By adopting the technical scheme, the application interfaces can be selectively preloaded in the process of preloading the application programs, namely, the preloading operation of some preset application interfaces is omitted, the preloading efficiency can be improved, the system resources can be saved, and the power consumption can be reduced.
In some embodiments, preloading the application to be preloaded includes: and displaying 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. And the preloading is carried out outside the screen, and the preloading process is invisible to a user, so that the display of the display content of the foreground application program on the display screen is not influenced.
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 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.
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.
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, the preset application interface includes a launch page interface and/or a preset toggle animation interface.
The start page is also called a flash screen (Splash screen), a launch Window (launch Window), a Preview Window (Preview Window), or the like, and generally refers to a first page of an open application, and is initially for the purpose that the application can be quickly opened to prevent a white screen or a black screen from appearing, a background can load a main page during display of the start page, and the start page is now commonly used to display information such as brands, campaign promotions, advertisements, and the like of an application program. The start page in the embodiment of the present application may be a static page or a dynamic page, where the dynamic page may include an animation page or a page that is continuously dynamically switched, and the embodiment of the present application is not particularly limited. When an Activity is opened, if the application program of the Activity is not running, the system creates a process for the application of the Activity, but the creation and initialization of the process take time, and before the action is completed, the user may think that the system does not have any reaction, and therefore, a start page is generated to solve the problem. A start page may be understood as a temporary window for display before the application process has successfully created and initialized, displaying the window before the program initialization is complete to inform the user that the system knows that he is about to open the application and responds, displaying a user operable human-machine interface (e.g., the main page of the application) when the program initialization is complete, and removing the start page window.
In some embodiments, when the preset application interface includes a start page interface, the prohibiting, in the preloading process, preloading of the preset application interface in the application program to be preloaded includes: in the preloading process, when detecting that a start page interface display function in the active window management service is about to be called, forbidding calling the start page interface display function. This has the advantage that the display of the start page interface can be inhibited quickly and accurately. Taking the android system as an example, a special function launching page interface display function (showStartingWindow) is provided in the activity management service (activity manager service) of the application program to process and display the launching page. Generally, when or after a process of an application program is created, a start page interface display function is called to avoid the occurrence of phenomena such as white screen or black screen, and therefore, when it is detected that the process of the application program to be preloaded starts to be created, it is considered that it is detected that the start page interface display function in the active window management service is about to be called, and at this time, the call of the start page interface display function is prohibited.
When the preset application interface includes a start page interface, prohibiting the pre-loading of the preset application interface in the application program to be pre-loaded in the pre-loading process, which may also include: in the preloading process, when a starting page interface display function in the active window management service is called, whether the current starting page interface belongs to an application program to be preloaded is judged through the starting page interface display function; and if so, forbidding displaying the current start page interface. The method has the advantages that whether the starting page interface to be displayed belongs to the application program to be preloaded can be accurately judged, and the starting page interface is timely stopped from being displayed when the starting page interface to be displayed belongs to the application program to be preloaded. The method and the device for displaying the starting page interface can reserve a calling step of a function for displaying the starting page interface, ensure the preloading stability of the application program, improve the function, and add a judging logic in the function, so that whether the starting page interface needing to be displayed currently belongs to the application program to be preloaded is judged in the function, if so, the starting page interface cannot be displayed, and the preloading of the starting page interface of the application program to be preloaded is forbidden.
In some embodiments, the determining, by the launch page interface display function, whether the current launch page interface belongs to an application to be preloaded includes: identifying a current starting page interface according to the window type through the starting page interface display function; and judging whether the current starting page interface belongs to the application program to be preloaded or not through the starting page interface display function. The advantage of this arrangement is that the start page interface can be accurately identified. Taking an android system as an example, the Type (Window Type) of the Window owned by the start page is Type _ APPLICATION _ STARTING, which is a unique identifier (flag) of the start page, the showStartingWindow function can accurately identify the start page according to the identifier, judge whether the start page interface belongs to the APPLICATION program to be preloaded, and if so, not display the start page interface. For example, it may be determined whether the application to which the launch page interface belongs is an application to be preloaded. Specifically, an identity of an active window stack where an application program to which a start page interface belongs is located may be obtained, and whether the identity is a preloaded identity is determined; if so, determining that the application program is a preloaded application program. The advantage of setting up like this is that can judge accurately fast according to the ID of Stack whether the application program that the start page interface belongs to is the preloaded application program.
In some embodiments, the preset application interface comprises a preset toggle animation interface. When an application program is opened or the operation such as active window switching is carried out, the system can generate animation, and the animation drawing needs to consume a large amount of resources such as a CPU/GPU.
Illustratively, when the preset application interface includes a preset switching animation interface, the prohibiting the pre-loading of the preset application interface in the application program to be pre-loaded during the pre-loading process includes: and in the preloading process, when detecting that a prepared application switching function in the window management service is about to be called, forbidding to call the prepared application switching function. The advantage of this is that the preloading of the default application interface can be quickly and accurately disabled. The preset animation switching interface may include an Activity switching animation interface, for example, an android system, and a typical Activity switching animation may include: activity openenteralliance, activity openexignation, taskfenenteralliance, taskfoseexignation, wallpaperopenenteralliance, wallpaperwallclosed enteralliance, and the like. The system sets and opens and switches the animation by calling the prepafacing transition function of the WindowManagerService. For example, the first step of the setting of the Activity switching animation generally sets the type of the Activity switching animation by calling the preparportransition function, and the currently common types may include, for example, transfer _ Activity _ OPEN, transfer _ Activity _ CLOSE, transfer _ TASK _ OPEN, transfer _ TASK _ CLOSE, transfer _ TASK _ TO _ FRONT, and transfer _ TASK _ TO _ BACK. The prepareAppTransition () function does essentially two things: the first one is to set the animation type into AppTransition, which will be used in subsequent operations; the second element is a 5s TIMEOUT message that sends an APP _ TRANSITION _ TIMEOUT. When the system is detected to start the setting of the Activity switching animation, the standby application switching function in the window management service is detected to be about to be called, and the calling of the standby application switching function is forbidden, so that the setting process of the Activity switching animation is finished from the first step, and the follow-up pre-loading operation of drawing, displaying and the like on the preset switching animation interface is forbidden.
For example, when the preset application interface includes a preset switching animation interface, the prohibiting the pre-loading of the preset application interface in the application program to be pre-loaded during the pre-loading process may also include: in the preloading process, when a prepared application switching function in the window management service is called, judging whether the current application program is an application program to be preloaded; if yes, terminating the calling of the prepared application switching function so as to forbid the preloading of a preset switching animation interface in the current application program. The method has the advantages that whether the current application program is the application program to be preloaded can be accurately judged, and if yes, the preloading of the preset switching animation interface of the current application program is forbidden in time in a mode of terminating function calling. In the embodiment of the application, the step of calling the application switching preparation function can be reserved, the stability of application program preloading is ensured, when the preparpAppTransition is called, the judgment logic is added, whether the current application program is the application program to be preloaded (namely whether the current application program starts preloading) is judged, whether the calling operation of the preparpAppTransition function is continued is determined, if yes, the function calling is terminated, so that the purpose that the animation is forbidden during preloading is achieved, the drawing speed can be accelerated, the power consumption is reduced, and the problem of animation abnormity caused by background animation to foreground animation can be avoided.
In some embodiments, after preloading the application program to be preloaded, the method further includes: and when receiving an operation instruction of a target application program in the application programs to be preloaded, starting the target application program based on the preloaded resources. After the application interface corresponding to the application program to be preloaded is displayed based on the pre-created stack of preloaded active windows, the method further includes: and when an operation instruction of a target application program in the application programs to be preloaded is received, migrating an application interface corresponding to the target application program contained in the preloading activity window stack to the display screen for displaying. The application interface corresponding to the target application program may include an application interface corresponding to an active window currently located at the top of the stack in a task stack corresponding to the target application program. The method has the advantages that the target application program can be quickly started in a mode of directly transferring the preloaded application interface to the display screen for displaying, the starting page and the preset switching animation are not in the preloading list, the application interface transferred to the display screen is an interactive interface which can be directly operated by a user, the user can operate the target application program without waiting, and the running efficiency of the target application program can be improved.
For example, fig. 4 is a schematic application interface migration diagram provided in the embodiment of the present application, and 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 schematic flowchart of another application preloading method provided in the embodiment of the present application, taking an android operating system as an example, the method includes the following steps:
step 501, when detecting that an application preloading event is triggered, determining an application program to be preloaded.

For example, the step of calling the showStartingWindow function is performed at the same time as the target process is created or when the target process is initialized.
For example, if no APPLICATION interface with a window TYPE of TYPE _ APPLICATION _ STARTING is found, it may be stated that there is no start page interface to be displayed currently, and step 606 may be directly performed.
