Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart illustrating a method for preloading an application program according to an embodiment of the present application, where the method may be performed by an apparatus for preloading an application program, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an intelligent terminal, as shown in fig. 1, and the method includes:
For example, the intelligent 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. And the intelligent terminal is provided with an operating system.
For example, there are many triggering manners of the operation instruction of the target application program, and the embodiment of the present application is not particularly limited. For example, the running instruction of the target application program can be triggered when the operation (including contact click operation and non-contact click operation) of clicking the target application program by the user is detected; or may trigger the running instruction of the target application program when detecting a user voice operation (e.g. a user voice input instruction of "turn on XX software"); or the operation instruction of the target application program can be automatically triggered according to the use habit data of the user, if the user gets up in the morning and turns on the chat software in a habit after the intelligent terminal is turned on, the system detects that the intelligent terminal is turned on in the morning, automatically predicts and preloads at least one application program including the chat software, and automatically triggers the operation instruction of the chat software. After the operation instruction of the application program is triggered, the system may detect the operation instruction of the target application program by reading the bit identifier or receiving the trigger instruction, and the specific detection method is not limited in this embodiment of the application.
And 102, when an operation instruction is detected, acquiring the attribute parameters of the display content within the coordinate range of the current display screen.
For example, the coordinate range of the current display screen may be understood as a coordinate range of the display screen on the smart terminal, and may include upper, lower, left and right coordinates in a coordinate system with the upper left corner of the display screen of the smart terminal as an origin, for example, (a, b, c, d) generally describes a rectangular boundary, and may be represented by coordinates of the upper left corner and coordinates of the lower right corner of the rectangle, that is, coordinates of the upper left corner of the rectangle are (a, b), and coordinates of the lower right corner of the rectangle are (c, d), and the coordinate range corresponding to such a rectangular area is the coordinate range of the current display screen. That is, when the attribute parameter of the display content is acquired, the attribute parameter of the display content in the coordinate range is acquired. Other display windows outside the coordinate range of the current display screen (such as an active window displaying the preloaded target application) are not included. The display content may be content information to be displayed on the display screen by the target application, for example, the display content of the news application is pictures, titles, news content, links and the like of various kinds of news. The attribute parameters of the display content may include brightness, contrast, saturation, color temperature, and the like corresponding to the display content when the display content is displayed in the display screen.
In the embodiment of the present application, when the operation instruction is detected, a specific process of obtaining the attribute information of the display content within the coordinate range of the current display screen is not limited, and the attribute information may be obtained from configuration information of the current display content, or obtained by analyzing a screenshot of the current display content.
And 103, adjusting an application interface to be displayed in the target application program according to the attribute parameters, and displaying the adjusted application interface.
For example, the application interface to be displayed in the target application may be a default display interface of the target application, for example, the default display interface in the WeChat application is a chat list interface. The application program may be a chat interface corresponding to XX, and the application interface to be displayed is a chat interface corresponding to XX, if the user last closes the chat interface corresponding to XX, the application program is controlled to load the set resource until the application interface is drawn and displayed when the application program is preloaded based on the pre-created preloaded active window stack. Or an application interface corresponding to the message pushed by the application program, for example, the user clicks the message information pushed by the system, and the application interface to be displayed at this time is a message pushing interface corresponding to the message pushed. It will be appreciated that for the case where the preloading is completed, the target application may be an application interface that the application program will display after the launch advertisement is played. For the case of incomplete preloading, the target application may be the application interface currently displayed in the preload Stack. For example, during the start-up of a shopping application, advertisements are typically displayed for a period of time. And if the shopping application program is preloaded, the application interface is the main interface of the shopping application program. However, if the operation instruction of the shopping application program is detected immediately after the advertisement is played for 3 seconds, the frame to be played in the 3 rd second of the advertisement is used as an application interface.
In the embodiment of the present application, acquiring an application interface to be displayed in a target application program includes: and migrating the task stack corresponding to the target application program contained in the preloading active window stack to the top of the application active window stack. It should be noted that, screens outside the coordinate range of the current display screen corresponding to the active window stack are preloaded, and screens within the coordinate range of the current display screen corresponding to the active window stack are applied. The task stack corresponds to the target application program, the active window corresponding to the target application program is started in the task stack, and the application interface corresponding to the target application program is drawn and displayed based on the active window, so that the application interface corresponding to the target application degree can be obtained by obtaining the task stack from the top of the application active stack, and the application interface is adjusted and displayed.
Optionally, the obtaining of the application interface to be displayed in the target application program may further be: and acquiring a task stack corresponding to the target application program from the preloading active window stack, thereby acquiring an application interface corresponding to the target application degree, adjusting the application interface, and migrating the adjusted task stack to the top of the application active window stack.
In the embodiment of the application, when the application interface to be displayed in the target application program is adjusted according to the attribute parameters, the acquired attribute parameters of the display content in the coordinate range of the current display screen may be integrally replaced with the attribute parameters of the application interface to be displayed in the target application program, the acquired attribute parameters may be sequentially compared with the attribute parameters of the application interface to be displayed, and when the two attribute parameters are not consistent, the attribute parameters in the application interface to be displayed are adjusted to the acquired attribute parameters. When the adjusted application interface is displayed, the application interface can be directly displayed on a display screen of the intelligent terminal, or the adjusted application interface can be acquired from the top of the movable window stack and displayed on the display screen of the intelligent terminal.
The application program preloading scheme provided in the embodiment of the application program detects the running instruction of the preloaded target application program, acquires the attribute parameters of the display content within the coordinate range of the current display screen when the running instruction is detected, adjusts the application interface to be displayed in the target application program according to the attribute parameters, and displays the adjusted application interface. By adopting the technical scheme, the application interface to be displayed in the target application program can be adjusted according to the attribute parameters of the display content of the current display screen, the preloading mode can avoid the problem that the display effect of the screen display content is greatly different before and after the application interface is switched, and the loading scheme of the application program is optimized.
In some embodiments, before detecting the execution instruction of the preloaded target application program, the method further includes: when detecting that an application preloading event is triggered, determining a target application program to be preloaded; and preloading an application interface corresponding to the target application program based on a pre-created pre-loaded active window stack, wherein the boundary coordinate corresponding to the pre-loaded active window stack is positioned outside the coordinate range of the display screen. The method has the advantages that the application interface of the application program needing to be preloaded can be preloaded based on the preloading active window stack created outside the display screen, the preloading mode can greatly complete the preparation work before the application is started, the starting speed of the target application program is improved, and the display of the display content of the foreground application program on the display screen cannot be 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 smart terminal has two or even more independent display screens, the "two screens" may also be two independent 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 where the application program is located may have its own size (size), and may include a rectangular area surrounded by upper, lower, left and right coordinates in a coordinate system with the upper left corner of the screen of the intelligent terminal as an origin, which corresponds to the size of the 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. Fig. 2 is a schematic diagram of a multi-window mode of an intelligent terminal according to an embodiment of the present disclosure, and as shown in fig. 2, a window 201 is a display screen on the intelligent terminal that is visible to both a system and a user, and a window 202 is a window outside the display screen that can be implemented by the intelligent terminal, where the window 202 is visible only to an operating system and is invisible to the user.
In the embodiment of the application, the application interface of the target application program 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. For example, the application interface of the target application program is preloaded in the window 202 in fig. 2, and the preloading process in the window 202 does not affect the display of the display content of the application program in the window 201 that can be seen by the user.
In general, in the multi-window mode, there may be multiple types of stacks, for example, Home Stack represents a Stack displayed by a desktop application, App Stack represents a Stack displayed by a third-party application, and there may be other split-screen stacks, and contents contained in the three types of stacks may be displayed on a display screen (e.g., a window 201 in fig. 2), and in this embodiment, they are collectively referred to as an application active window Stack. 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 dedicated for displaying the preloaded application may be newly established based on a multi-window mechanism of the Android system, for example, a Stack dedicated for displaying the preloaded application is established in the window 202 in fig. 2. 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, a specific process of preloading an application interface corresponding to a target application program 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, before adjusting the application interface to be displayed in the target application according to the attribute parameter, the method further includes: migrating a task stack corresponding to the target application program contained in the preloading active window stack to the top of an application active window stack; and updating the size information, the configuration information and the visibility of the task stack to realize that the application interface corresponding to the target application program is displayed on the display screen. The advantage that sets up like this lies in, can guarantee the stability of interface migration process, guarantees that the card screen can not appear in the recovery process, the black screen or the migration speed is slow scheduling problem.
In addition, fig. 3 is a schematic application interface migration diagram provided in the embodiment of the present application, as shown in fig. 3, when an operation instruction of a target application program is received, attribute information of display content of a current display screen 301 is acquired, a preloaded application interface 302 corresponding to the target application program included in a preloaded active window Stack is adjusted based on the acquired attribute information, and the adjusted preloaded application interface 302 is migrated to the display screen 301 to be displayed, specifically, a task to which the preloaded application interface belongs is migrated to the top of an application active window Stack, size information, configuration information, and visibility of the task are updated, and attribute information of the preloaded application interface is adjusted, so that the preloaded application interface 302 can be normally displayed on the display screen 301 and a problem of a sudden change in display effect does not occur.
For some intelligent terminals, especially for intelligent terminals such as mobile phones and tablet computers, in order to facilitate the use of users, the display mode of the display screen generally includes 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 online games), and some applications switch the horizontal and vertical screen display along with the direction in which the user holds the intelligent terminal during the use of the intelligent 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. 4 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. 4, at this time, the display screen is in a vertical screen mode, the origin of the system coordinates of the intelligent terminal is the left vertex (0,0) of the display screen 301, the width direction of the display screen 301 is the X axis, the height direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack401 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. 5 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. 5, at this time, the display screen is in a landscape mode, the origin of the system coordinates of the intelligent terminal is the left vertex (0,0) of the display screen 501, the height direction of the display screen 501 is the X axis, the width direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack401 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, preloading an application interface corresponding to the target application program based on a pre-created preloaded active window stack includes: creating a target process corresponding to the target application program; creating a task stack corresponding to the target application program in a pre-created preloading active window stack; starting an active window corresponding to the target application program in the task stack based on the target process; and drawing and displaying an application interface corresponding to the target application program based on the started active window. The advantage of setting up like this lies in, can draw and show the application interface of target application program based on the preloading activity window stack outside the screen coordinate scope, can not disturb the operation and the demonstration of foreground application program, guarantees system stability, effectively improves the speed when target application program starts simultaneously. While creating the target process, an initialization process of the target process may also be included. In the execution process of the above steps, preloading of other resources may also be involved, such as application service starting, memory allocation, file content reading, network data acquisition, and the like.
In some embodiments, further comprising: and sending a fake focus notification to the target application program, and keeping continuous drawing and display updating of an application interface corresponding to the target application program within a preset time period based on the fake focus notification, wherein the length of the preset time period comprises the playing time of starting an advertisement or starting an animation in the target application program. The method has the advantages that the drawing and the display of the application interface can be completed under the condition that the target application program 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 the start advertisement or start animation in the target application program. Some application programs usually play some advertisements or animations during the starting process, the playing time of the advertisements or animations usually ranges from 3 seconds to ten seconds, and during the playing of the advertisements or animations, a user may not have any operation and only wait for the completion of the playing, which wastes valuable time of the user. The method and the device have the advantages that the starting advertisement or the starting animation can be played out of the screen before the target application program is started, and when the target application program is started, the main page or other user operable interfaces of the application program can be directly accessed, so that the operable time point of the target application program is further advanced, and the waiting time is reduced.
In some embodiments, when the execution instruction is detected, acquiring an attribute parameter of the display content within the coordinate range of the current display screen includes: when the operation instruction is detected, acquiring a screenshot of a current display screen; and determining the attribute parameters of the display content within the coordinate range of the current display screen according to the screenshot. The method has the advantages that the attribute parameters of the display content within the coordinate range of the current display screen are obtained through the screenshot, and the efficiency and the accuracy of obtaining the attribute parameters can be improved.
In some embodiments, adjusting an application interface to be displayed in the target application according to the attribute parameter, and displaying the adjusted application interface includes: and acquiring an application interface to be displayed by the target application program, adjusting the display effect of the application interface according to the attribute parameters, and displaying the adjusted application interface within the coordinate range of the current display screen. The advantage of setting up like this lies in, can guarantee that the display effect difference of the display content before the application interface after the adjustment and switching is less, has avoided the problem of display effect sudden change.
Fig. 6 is a flowchart of another method for preloading an application program according to an embodiment of the present application, where the method includes the following steps:
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., pick up of the smart terminal, input of a screen unlocking operation, input of a smart 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.
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. The target application program can be understood as the application program to be preloaded which needs to be preloaded currently. The target application may also include one or more. When only one application program to be preloaded exists, only one corresponding target application program exists; when there are multiple application programs to be preloaded, the target application program may be one (that is, multiple application programs to be preloaded are determined as target application programs one by one and are sequentially subjected to a preloading operation), or multiple (that is, more than 2 application programs to be preloaded are determined as target application programs and are simultaneously subjected to a preloading operation, that is, the preloading processes of the multiple target application programs may be performed in parallel).
Alternatively, a prediction model may be used to predict the application to be preloaded. Determining the target application program to be preloaded may include determining the target application program to be preloaded according to an output result before the prediction model, or may include performing prediction by using the prediction model and determining the target application program to be preloaded according to a current output result of the prediction model.
In the embodiment of the application, the creation time of the target process corresponding to the target application program is not limited, and the preloading Stack can be set to be in a resident state by default before the intelligent terminal leaves a factory, namely the preloading Stack exists all the time; the method can also be established when the intelligent terminal is started or after the intelligent terminal is successfully unlocked; it may also be created after an application preload event is triggered (which may be before the target application is determined), and so on.
Optionally, before creating the target process corresponding to the target application program, it may be determined whether a pre-created pre-loaded active window stack exists first, and if not, the pre-loaded active window stack is created according to a preset rule, then the target process corresponding to the target application program is created, and the target process is initialized. The method has the advantages that after the target 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 target application includes a plurality of applications, that is, when a plurality of applications need to be continuously preloaded in a short time, the preloaded Stack is already created before the first target application starts to load, and then the preloaded Stack exists before the second target application starts to load, which may not be necessary to make the above determination
And step 604, starting an active window corresponding to the target application program in the task stack based on the target process.
And step 605, sending a fake focus notification to the target application program, and keeping continuous drawing and display updating of the application interface corresponding to the target application program in a preset time period based on the fake focus notification.
The length of the preset time period comprises the playing time length of starting the advertisement or starting the animation in the target application program.
And 606, drawing and displaying an application interface corresponding to the target application program based on the started active window.
And 608, acquiring a screenshot of the current display screen when the operation instruction is detected.
When an operation instruction is detected, a screenshot of the current display content on a display screen of the intelligent terminal is automatically obtained, and the attribute information of the current display content can be obtained through the screenshot and used for adjusting the attribute information of the target application program.
And 609, determining the attribute parameters of the display content within the coordinate range of the current display screen according to the screenshot.
The area of the screen capture can be determined by the coordinate range of the display screen, and the attribute parameters of brightness, contrast, saturation, color temperature and the like of the display content in the coordinate range of the current screen can be obtained according to the image attribute information of the screen capture.
And when the running instruction is detected, migrating a task stack corresponding to the target application program contained in the preloading active window stack to the top of the application active window stack.
Specifically, taking an application active window as an App Stack as an example, moving the task to the App Stack may include: this task is removed from the list in the original Stack (i.e., the preloaded Stack) and added at the top in the new Stack (app Stack). Each stack has a list for recording all the tasks contained in the stack; correspondingly, each task will record the stack information of the task at the same time. Since a stack contains attributes such as size, configuration, visibility, and zorder, which may be different from other stacks, the attributes such as zorder of the task may be changed simply by adding the task to the list of the new stack. The top added in the new stack is to make the task visible.
And 611, updating the size information, the configuration information and the visibility of the task stack to display the application interface corresponding to the target application program on a display screen.
It can be understood that, in the preloading process, the application interface corresponding to the target application program is in the continuous drawing and display updating process, and the timing when the user really starts the target application program is uncertain, and may receive an operation instruction in the preloading process, so that the application interface currently displayed in the preloading Stack may be migrated to the display screen for display. If the user opens the target application program after the preloading is completed, the last application interface when the preloading is completed can be migrated to the display screen to be displayed.
Specifically, the updating of the size information and the configuration information of the task stack is to change the boundary of the application, and may specifically include: actively updating the size and configuration information. The size and configuration of the task cannot be changed immediately only by using the above task migration operation, so that the method for modifying the size and configuration of the task can be actively called, the application state is ensured to be correct, and the application can normally work in the foreground.
Specifically, the update task is visible because, after the size and configuration are updated, the target application may not be visible at this time, the method of updating the stack visibility is invoked, the visible applications are searched from top to bottom, set to visible, and the corresponding window surface is updated to visible. The visible application judgment method may include: is not occluded by other applications on the zorder; is not shielded by the lock screen; the state of the top activity of the application is a non-initializing or non-exiting state.
It should be noted that, the execution sequence of step 608 and step 609 and step 610 and step 611 is not limited in this embodiment, and the execution sequence may be according to the sequence described in this embodiment, or step 610 and step 611 may be executed first, and then step 608 and step 609 are executed, or step 608 and step 609 and step 610 and step 611 are executed in parallel.
And 612, acquiring an application interface to be displayed of the target application program, adjusting the display effect of the application interface according to the attribute parameters, and displaying the adjusted application interface within the coordinate range of the current display screen.
According to the application program preloading method, the application interface of the application program to be preloaded can be drawn and displayed based on the preloading movable window stack established outside the display screen, when the running instruction is detected, the application interface to be displayed in the target application program is adjusted according to the attribute parameters of the display content of the current display screen, the preloading mode can complete preparation work before application starting to a large extent, the starting speed is effectively improved, meanwhile, the problem that the display effect is greatly different before and after the screen display content is switched on the application interface can be avoided, and the application program loading scheme is optimized.
