Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a management method for preloaded applications according to an embodiment of the present application, where the method may be performed by a management apparatus for preloaded applications, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an intelligent terminal. As shown in fig. 1, the method includes:
and step 110, determining the application program to be preloaded.
For example, the intelligent terminal in the embodiment of the present application may include terminal devices such as a smart phone, a tablet computer, a notebook computer, a handheld game console, and an intelligent appliance. And the intelligent terminal is provided with an operating system.
It should be noted that the application to be preloaded may be understood as an application that a user may be about to open, 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.
For example, the application program to be preloaded may be determined when an application preloading event is detected to be triggered. 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.
Alternatively, a prediction model may be used to predict the application to be preloaded. The prediction model may be a machine learning model, and the algorithm used may include a Recurrent Neural Networks (RNN), a Long Short-Term Memory (LSTM) network, a threshold cycle unit, a simple cycle unit, an auto-encoder, a decision tree, a random forest, a feature mean classification, a classification regression tree, a hidden markov, a K-nearest neighbor (KNN) algorithm, a logistic regression model, a bayesian model, a gaussian model, and a KL divergence (Kullback-Leibler) or the like.
Optionally, in the process that the user uses the terminal, a training sample may be collected, the training sample is adopted to train the preset initial model, and finally, a prediction model for predicting the application program to be preloaded is obtained. For example, the elements contained in the training sample may include a time sequence or an order sequence in which the application was opened; can include the time, place, frequency, etc. that the application was opened; the method can include the running state of the terminal, such as the on-off state of a mobile data network, the connection state of a wireless hotspot, the identity information of the connected wireless hotspot, the currently running application program, the previous foreground application program, the stay time of the current application program in the background, the last time the current application program is switched to the background, the plugging state of an earphone jack, the charging state, the battery power information, the screen display time and the like; and the data collected by sensors integrated in the terminal can be included, such as a motion sensor, a light sensor, a temperature sensor, a humidity sensor and the like.

And 120, preloading an application interface corresponding to the application program based on the pre-created preloading active window stack.
It should be noted that, an active window Stack (preloaded Stack) is preloaded to indicate a Stack displayed by the preloaded application, and the boundary coordinates of the preloaded Stack are set to be outside the coordinate range of the display screen, where the application program to be preloaded can be displayed. The boundary coordinates corresponding to the preloaded active window stack are outside the coordinate range of the display screen.
In the embodiment of the present application, the active window may be understood as a separate interface directly providing interaction and operation for a user, and different names may be used in different operating systems to name the interface. For ease of understanding, the following description will be made taking an Android (Android) operating system as an example.
In the Android system, the active window is called Activity. Activity is a component responsible for interacting with a user that provides a screen (which may be understood as a screen interface, rather than a display screen of an entity) for the user to interact to accomplish a task. In an android application, an Activity is usually a separate screen on which controls can be displayed and events of the user can be monitored and processed. In managing Activity, there are two concepts: task Stack and Stack. The Task corresponds to an application program, the Task is used for storing activities, one Task can store one or more activities, and the activities follow the principle of first-in first-out and last-in first-out. And the Stack is used for managing the Task, generally, one Stack manages the Task to which each Activity required to be shown by one screen belongs, and one Stack can manage one or more tasks, and of course, the Stack also follows the basic management principle of the Stack. The screens described herein are not necessarily completely separate display screens, and in the case of "two screens", the two screens may be only two regions of a complete display screen that independently display respective display contents. Of course, if the terminal has two or even more separate display screens, the "two screens" may also be two separate display screens.
In the Android system, multi-window modes are supported, which may include split screen mode, picture-in-picture mode, and free mode (FreeForm). In the multi-window mode, the Stack in which the application is located may have its own size (size), and may include upper, lower, left, and right coordinates in a coordinate system with the upper left corner of the terminal screen as the origin. For example, (a, b, c, d), which generally describes the boundary of a rectangle, the coordinates of the upper left corner and the coordinates of the lower right corner of the rectangle can be used for representation, i.e. the coordinates of the upper left corner of the rectangle are (a, b), and the coordinates of the lower right corner are (c, d), and such a rectangular area corresponds to the size of Stack. The in-application layout in the Stack is based on the size of the Stack, that is, the application interface corresponding to Activity is displayed within the boundary range of the size.
In the multi-window mode, multiple applications may be allowed to be visible, including both system and user visibility and system-only visibility. The system and the user can see the display on the display screen, and the user can see the display; system-only-visible means that the operating system is visible, but not the user, and may be obscured by foreground applications or displayed outside the display screen as the application is intended to implement.
In the embodiment of the application, the application interface of the 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.
Generally, in the multi-window mode, there may be multiple types of stacks, for example, Home Stack represents a Stack displayed by a desktop application, App Stack represents a Stack displayed by a third-party application, and there may be other split-screen stacks, and contents contained in the three types of stacks may be displayed on a display screen, which are collectively referred to as application active window stacks in this embodiment.
Illustratively, the preloading of the application interface corresponding to the application program based on the pre-created preloading active window stack includes: creating a target process corresponding to the application program; creating a task stack corresponding to the application program in a pre-created preloading active window stack; starting an active window corresponding to the application program in the task stack based on the target process; drawing and displaying an application interface corresponding to the application program based on the started active window. The advantage that sets up like this lies in, can draw and show application program's application interface based on the preloading activity window stack outside the screen coordinate range, can not disturb the operation and the demonstration of foreground application program, guarantees system stability, effectively improves the speed when the 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 the embodiment of the application, the user operation includes an operation of adjusting the setting information of the intelligent terminal by a user or an operation of an application program of the intelligent terminal by the user. It should be noted that the user operation may be a touch operation applied to the touch screen, or a spatial gesture operation, or may also be a facial expression or a voice operation, or the like. The opening rate may be understood as the probability that the preloaded application is run. After a large number of users use the application preloading function, the use conditions of application programs (including preloaded application programs and non-preloaded application programs) corresponding to different user operations can be obtained, the association relationship between different user operations and the running probability of the preloaded application programs is analyzed from the use data based on a big data statistics mode, and the association relationship can be stored in a preset white list mode. Such as predicting the application to be preloaded as a payment application, e.g., a payment treasure, WeChat, etc., based on the user historical usage records. After the payment application to be preloaded is preloaded, if it is detected that the user sets the intelligent terminal to be in a flight mode, the user does not use the intelligent terminal for a long time under the scene through big data statistics, the probability that the preloaded payment application is operated is considered to be extremely low (if the value range of the opening rate is 0-1, the value range is equally divided into 0-0.3, 0.4-0.6 and 0.7-13 gears, at this moment, the opening rate of the payment application can be considered to be 0-0.3, and the opening rate can be further determined by combining the prediction probability of the preloading model), and the setting information and the opening rate are stored in a preset opening rate table in an associated mode. In a similar way, the incidence relation between different setting information and the opening rate can be analyzed, and the incidence relation between the operation of different application programs and the opening rate can be analyzed.
For example, the intelligent terminal detects a user operation, and after the user operation is detected, queries a preset opening rate table according to the user operation to determine an opening rate of a preloaded application program corresponding to the user operation. And the opening rate table stores the opening rate of the user operation and the application program in a related manner. After determining the turn-on rate of the preloaded applications, a priority may be assigned to each preloaded application based on the turn-on rate. In the embodiment of the present application, the priority is used to indicate the order in which the processes of the application programs are killed, and it is understood that the process of the preloaded application program with higher priority is later than the process of the preloaded application program with lower priority. The method has the advantages that after the user operation is obtained, the probability that the preloaded application program is started can be conveniently predicted, and the intelligent terminal can conveniently execute the process cleaning operation based on the starting rate so as to clean the memory.
And step 140, when a preset closing condition is met, executing a closing operation on the application program based on the priority.
It should be noted that the preset shutdown condition may be the existence time of the preloaded application program, or detect that an application preloading event is triggered, etc. It is to be understood that the preset off condition is not limited to the above-listed manner.
In this embodiment of the present application, after assigning a priority to the application program according to the opening rate, the method further includes: and acquiring the preloading completion time of the last application program to be preloaded. And if the difference value between the current system time and the preloading completion time exceeds a preset time threshold value, determining that a preset closing condition is met. And when the preset closing condition is met, closing at least one application program at preset time intervals according to the sequence of the priority from low to high. If the application programs to be preloaded are application A, application B, application C, application D and application E, and the application programs to be preloaded are preloaded according to the sequence. And recording the preloading completion time of the application E when the application E is preloaded. And if the difference value between the current system time and the preloading completion time exceeds a preset time threshold value, determining that a preset closing condition is met. If the priority of the preloaded application program is from high to low, the application program is respectively an application A, an application C, an application B, an application E and an application D. And when the preset closing condition is met, closing operation is executed according to the sequence of the application D, the application E, the application B, the application C and the closing application A every 20 minutes.
Alternatively, after assigning the priority to the application program according to the opening rate, the method may further include: and monitoring application preloading events. And if the application preloading event is triggered, determining that a preset closing condition is met. And when detecting that the application preloading event is triggered, closing at least one application program according to the priority order, wherein the priority of the application program is associated with the opening rate and the preloading completion time. It can be understood that the intelligent terminal triggers the application preloading event when the triggering condition of the application preloading event is met. If the application preloading event is triggered, the intelligent terminal can be determined to meet the preset closing condition, the preloaded application programs are arranged in a descending order according to the priority, the closing operation is executed from the tail of the queue, and the number of the closed application programs can be set by a system default or a user. If the application programs to be preloaded are application A, application B, application C, application D and application E, and the application programs to be preloaded are preloaded according to the sequence. If the priority of the preloaded application program is from high to low, the application program is respectively an application A, an application C, an application B, an application E and an application D. And when detecting that the application preloading event is triggered, closing the application D and the application E according to the preset closing number. And when detecting that the application preloading event is triggered, preloading the newly determined application programs (application L, application N, application O, application Q and application X) to be preloaded. And detecting the user operation, and determining the opening rates of all the current preloaded application programs (application L, application N, application O, application Q, application X, application A, application C and application B) based on the user operation. It is understood that the priority of the application program is re-determined based on the opening rate of the application program and the preload completion time. And by analogy, when the application preloading event is detected to be triggered, the two application programs at the tail of the queue are closed according to the redetermined priority of the application programs.
It should be noted that, in this embodiment of the present application, the closing operation performed on the preloaded application program may be to log off a process corresponding to the application program, or may also be to delete a resource preloaded by the application program after logging off the process, and the present application is not limited in particular.
According to the technical scheme of the embodiment, the application program to be preloaded is determined; preloading an application interface corresponding to the application program based on a pre-established preloading active window stack; acquiring user operation, determining the opening rate of the preloaded application program according to the user operation, and distributing priority to the application program according to the opening rate; and when a preset closing condition is met, executing closing operation on the application program based on the priority. By adopting the technical scheme, the application interface of the application program needing to be preloaded can be preloaded based on the preloading movable window stack established outside the display screen, the starting speed of the target application program is improved, and the display of the display content of the foreground application program on the display screen is not influenced; meanwhile, the priority is distributed to the application programs which are already preloaded based on user operation, the closing operation can be executed on the application programs according to the priority, and the phenomenon that the memory utilization rate of the intelligent terminal is influenced due to the process residency of the preloaded application programs is avoided.
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 in a preset time period based on the fake focus notification. 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, after preloading the application interface corresponding to the target application program based on the pre-created preloading active window stack, the method further includes: and when an operation instruction of the target application program is received, transferring an application interface corresponding to the target application program contained in the preloading active window stack to the display screen for displaying. The method has the advantages that when the target application program really needs to be started, the drawn application interface is directly migrated to the display screen to be displayed, the application interface can be rapidly switched, and the starting speed is improved.
In some embodiments, the migrating an application interface corresponding to the target application program included in the preloaded active window stack to the display screen for display includes: migrating a task stack corresponding to the target application program contained in the preloading active window stack to the top of an application active window stack; and updating the size information, the configuration information and the visibility of the task stack to realize that the application interface corresponding to the target application program is displayed on the display screen. The advantage that sets up like this lies in, can guarantee the stability of interface migration process, guarantees that the card screen can not appear in the recovery process, the black screen or the migration speed is slow scheduling problem.
For some terminals, especially for intelligent 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 online games), and some applications switch the horizontal and vertical screen display along with the direction in which the user holds the terminal during the use of the terminal. In some embodiments of the present application, a boundary coordinate corresponding to the preloaded active window stack is (H, 0, 2H, H), a coordinate system corresponding to the boundary coordinate is a system coordinate, an origin of the system coordinate is an upper left corner of the display screen, and H is a length of a long side of a display area of the display screen. That is, the side corresponding to H is the maximum side of the display area of the display screen, and is the height of the display screen in the vertical screen display and the width of the display screen in the horizontal screen display. This is done to allow for the display of a landscape screen, pre-loaded application landscape displays, and the normal display of some applications. Fig. 2 is a schematic diagram illustrating a relative position relationship between a preloaded active window stack and a display area of a display screen according to an embodiment of the present disclosure. As shown in fig. 2, at this time, the display screen is in a vertical screen mode, the origin of the terminal system coordinates is the left vertex (0,0) of the display screen 201, the width direction of the display screen 201 is the X axis, the height direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack202 are (H, 0, 2H, H), H is the screen height, that is, the area in the left solid line rectangular range is the main screen display area, and the area in the right dotted line rectangular range is the preloaded display area. Fig. 3 is a schematic diagram illustrating a relative position relationship between a preloaded active window stack and a display area of a display screen according to an embodiment of the present application. As shown in fig. 3, at this time, the display screen is in a landscape mode, the origin of the terminal system coordinates is the left vertex (0,0) of the display screen 301, the height direction of the display screen 301 is the X axis, the width direction is the Y axis, the boundary coordinates corresponding to the preloaded Stack202 are (H, 0, 2H, H), H is the screen height, that is, the area in the left solid line rectangular range is the main screen display area, and the area in the right dotted line rectangular range is the preloaded display area.
The reason why the pre-loaded Stack boundaries are so set is that:
the abscissa of the upper left corner is H, which is an interface for preventing the display screen (also referred to as a main screen) from displaying the preloaded application during the landscape screen, and since the main screen has a landscape mode in addition to the portrait mode, the abscissa of the upper left corner of the rectangular area corresponding to the preloaded Stack is set to the screen height in order to prevent the main screen display area from displaying the local part of the preloaded application during the landscape screen of the main screen.
The ordinate in the upper left corner is 0 in order for the preload application to be able to calculate the status bar height correctly. In order to better design a User Interface (UI), the Android application can customize the top status bar, and if the vertical coordinate corresponding to the upper edge is not equal to 0, the height of the status bar may be wrong.
The abscissa of the lower right corner is 2H (2 times the screen height), that is, the width of the rectangle corresponding to the preloaded Stack is equal to the screen height, so that the size of the preloaded Stack can contain the landscape application at the time of preloading (that is, the application interface is an application program in a landscape display mode).
The ordinate of the lower right corner is H, i.e. the height of the rectangle corresponding to the preloaded Stack is equal to the screen height, so as to preload the size of the Stack and be able to contain the vertical screen application at the time of preloading.
For the reasons described above, the inventors set the size of the preload Stack to (H, 0, 2H, H).
In addition, fig. 4 is a schematic application interface migration diagram provided in the embodiment of the present application, as shown in fig. 4, when an operation instruction of a target application program is received, an application interface 401 corresponding to the target application program included in a preloaded active window Stack is migrated to a display screen 201 to be displayed, specifically, a task to which the preloaded application interface belongs is migrated to the top of an application active window Stack, and size information, configuration information, and visibility of the task are updated, so that the application interface can be normally displayed on the display screen.
Fig. 5 is a flowchart of another management method for preloaded applications according to an embodiment of the present application, where the method includes:
The intelligent terminal judges whether a preset triggering condition of the application preloading event is met, and if yes, the application preloading event is triggered.
In the embodiment of the application, the creation time of the preloaded active window Stack (namely, 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; it may also be created after an application preload event is triggered (which may be before the target application is determined), and so on.
And step 504, creating a preloading active window stack according to a preset rule.
After the step is completed, the step 505 is continued.
Illustratively, if a pre-created pre-loaded active window stack does not exist, creating the pre-loaded active window stack according to a preset rule; and preloading an application interface corresponding to the target application program based on the created preloading active window stack. 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 a plurality of target applications are included, 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.
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.
And 505, creating a target process corresponding to the application program, and initializing the target process.
And 507, starting an active window corresponding to the application program in the task stack based on the target process, and sending a fake focus notification to the target application program.
And step 508, updating the focus flag bit corresponding to the application program according to the fake focus notification, and continuously drawing and updating the application interface corresponding to the application program based on the started active window within a preset time period.
It should be noted that the user operation may be an operation of adjusting setting information of the intelligent terminal, such as controlling the intelligent terminal to be in a flight mode or a conference mode, or adjusting screen brightness (possibly, the user is tired, and then the opening rate of the preloaded game application is reduced), and the like; the user action may also be to launch a new application, which may also trigger an application preload event.
It should be noted that, the opening rate table stores the association relationship between the user operation and the opening rate of the application program, for example, the user operation and the application program are stored in the opening rate table in a one-to-many mapping relationship. The application program may be an installed application program in the intelligent terminal, or may be only a preloaded application program, and the application is not particularly limited.
Illustratively, the application programs are assigned priorities in sequence according to descending order of the opening rates and the priority is from high to low, that is, the higher the opening rate of the application program is, the higher the priority is.
And 510, judging whether the intelligent terminal meets a preset closing condition of the preloaded application program, if so, executing step 511, and otherwise, executing the step again after waiting for a preset time.
And 511, executing closing operation on the application program based on the priority.
It should be noted that closing the application may be killing a process of the application.
It should be noted that the target application may be understood as an application to be preloaded that currently needs to perform a preloading operation. 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).
Illustratively, the operation instruction of the target application program is received, and the preloaded application programs which are not closed are inquired according to the application identification of the target application program. If the target application is a preloaded application and its process is not killed, step 513 is performed.
And 513, migrating the task stack corresponding to the target application program contained in the preloaded active window stack to the top of the 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 514, updating the size information, the configuration information and the visibility of the task stack to display the current application interface corresponding to the target application program on a display screen.
It 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, a method of updating the visibility of the new stack is invoked, the visible applications are searched from top to bottom, set to visible, and the corresponding window surface is updated to visible. The visible application judgment method may include: is not occluded by other applications on the zorder; is not shielded by the lock screen; the state of the top activity of the application is a non-initializing or non-exiting state.
And if the target application program is not the preloaded application program or the target application program is the preloaded application program but the process of the target application program is searched and killed, loading the target application program according to a conventional loading flow.
According to the management method for the preloaded application, after the application program is preloaded, the priority can be allocated to the preloaded application program according to user operation, when the preset closing condition is met, the progress of a part of the preloaded application program can be ended according to the priority, the memory resource is prevented from being occupied for a long time, and therefore the processing speed of the intelligent terminal is improved. In addition, all the preloaded application programs are not closed at one time, the problem that a user needs to use the preloaded application programs and needs to reload the application programs is avoided, and therefore the starting speed is effectively improved.
