Detailed ways

The technical solutions of the present application will be further described below with reference to the accompanying drawings and specific embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. It should also be noted that, for convenience of description, the drawings only show a part of the structure related to the present application, but not the entire structure.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart describes the steps as sequential processing, many of the steps can be performed in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged. The process may be terminated when its operation is completed, but may also have additional steps not included in the drawings. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and so on.

FIG. 1 is a schematic flowchart of an application preloading method according to an embodiment of the present application. The method may be executed by an application preloading device, where the device may be implemented by software and / or hardware, and may generally be integrated in a terminal. As shown in FIG. 1, the method includes steps 101 to 103.

In step 101, when it is detected that an application preload event is triggered, an application program to be preloaded is determined.

Exemplarily, the terminal in the embodiments of the present application may include terminal devices such as a mobile phone, a tablet computer, a notebook computer, and smart home appliances. The terminal is loaded with an operating system.

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

Exemplarily, the application to be preloaded can be understood as an application that the user may open soon, it can be a fixed application that is set in advance, or an application that is predicted in a certain manner. The applications to be preloaded may include one or more.

In one embodiment, a prediction model may be used to make predictions on the application to be preloaded. The prediction model can be a machine learning model, and the algorithms used can include Recurrent Neural Networks (RNN), Long Short-Term Memory (LSTM) networks, threshold recurrent units, simple recurrent units, automatic encoding , Decision tree, random forest, feature mean classification, classification regression tree, hidden Markov, K-NearestNeighbor (KNN) algorithm, logistic regression model, Bayesian model, Gaussian model, and KL divergence (Kullback – Leibler divergence) and so on.

In one embodiment, during the process of using the terminal by the user, training samples can be collected, the preset initial model can be trained by using the training samples, and finally a prediction model for predicting the application to be preloaded can be obtained. Exemplarily, the elements included in the training sample may include a time series or sequence sequence in which the application is opened; may include the time, place, and frequency of the application being opened; and may include a running state of the terminal, such as a switch of a mobile data network Status, the connection status of the wireless hotspot, the identity information of the connected wireless hotspot, the currently running application, the previous foreground application, the length of time the current application stays in the background, the time when the current application was last switched to the background, The plugging and unplugging status, charging status, battery power information, and screen display duration of the headphone jack; it can also include data collected by sensors integrated in the terminal, such as motion sensors, light sensors, temperature sensors, and humidity sensors.

Exemplarily, an appropriate sample element can be selected according to the selected machine learning model, and the selected machine learning model can be determined according to the selected sample element. It can also be combined with the requirements of prediction accuracy and preset speed. The selection of models and sample elements is not limited in the embodiments of the present application.

In the embodiment of the present application, determining the application to be preloaded may include determining the application to be preloaded according to the output result before the prediction model, or may include performing prediction using the prediction model to determine the current output result of the prediction model to determine the application to be preloaded. .

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

Exemplarily, the prediction model described above may be used to determine the startup probability of each candidate application. For example, according to the training samples during prediction model training, current samples are collected, and the current samples are input into the prediction model to obtain the startup probability of each candidate application. The startup probability can be sorted from high to low, and the candidate N applications (N is a preset value) are determined as the applications to be loaded. This setting can preload multiple applications, and these multiple applications are determined according to the startup probability, which can improve the accuracy of the prediction.

In step 102, a preloading operation is performed on the application program to be preloaded, and a preloading process is monitored.

In the embodiment of the present application, when there is only one application to be preloaded, there is no need to consider the preloading order of the applications; and when there are multiple applications to be preloaded, the multiple applications to be preloaded may be determined one by one as the current one. Applications to be preloaded and preloaded in sequence. You can also determine more than 2 applications to be preloaded as the current to be preloaded and perform preloading operations at the same time, which means that multiple applications are preloaded. The loading process can be performed in parallel.

In the embodiment of the present application, the specific process of preloading and the resources loaded are not limited. For example, corresponding hardware resources may be allocated to the application to be preloaded, and related data required for startup may be loaded based on the allocated hardware resources. Exemplarily, it may include application process startup, application process initialization, application service startup, memory allocation, file content reading, network data acquisition, and interface rendering (such as drawing a startup screen of an application or other application interfaces) and the like. In addition, pre-loaded resources can also be determined according to the specific type of application to be pre-loaded.

In the process of performing the preloading operation, the embodiment of the present application monitors the preloading process, so that during the preloading phase of the application, that is, before the application is actually started, the loading abnormality of the application startup resource is found in time. The specific monitoring content can be determined according to the actual situation. Exemplarily, a situation that is prone to occur when the application is started and / or a cause of the situation may be determined through research and other methods, and the corresponding preloaded content is further determined and detected in real time. For example, some applications may crash when they are launched (for example, they appear to crash after a short period of time after the application starts). You can detect whether the application to be preloaded will crash during the preloading phase; and For example, when some applications are launched, page loading errors may occur. You can also check whether the page is successfully loaded during the preloading phase.

In step 103, if an abnormality is detected during the preloading process, the abnormality is processed.

In the embodiment of the present application, when an abnormality is detected during the preloading process, targeted processing may be performed according to the type or severity of the abnormality that occurs. Exemplarily, the cause of the abnormal situation may be analyzed, and repair processing shall be performed for the cause, and the preload operation of the current to-be-preloaded application program may be continued or re-exemplified; and as an example, the cause of the abnormal situation may not be analyzed. Or, when the cause of the abnormal situation cannot be analyzed, reload the current application to be preloaded. In the above manner, the probability that the pre-loaded application program starts abnormally when it is actually started can be effectively reduced.

In the application preloading scheme provided in the embodiment of the present application, when it is detected that an application preloading event is triggered, an application to be preloaded is determined, a preloading operation is performed on the preloaded application, and a preloading process is monitored. When an abnormality is detected during the preloading process, the abnormality is processed. By adopting the above technical solution, anomaly detection can be performed in the preloading phase of the application, and processing can be performed when an abnormality is detected, thereby improving the preloading function.

In some embodiments, when a run instruction of a target application in the application to be preloaded is received, the target application is started based on a preloaded resource of the target application. In this way, when the user actually launches an application that has been preloaded, the resources used for startup have been partially or fully preloaded, and anomaly detection has been performed during the preloading process, which can improve the speed of application startup. To increase the probability of the application launching normally.

In some embodiments, performing the preloading operation on the application to be preloaded includes: simulating starting the application to be preloaded outside a coordinate range of a display screen. Exemplarily, a virtual screen area may be set outside the coordinate range of the display screen. For an application to be preloaded currently, the current to-be-loaded application is opened in the virtual screen area based on the preloaded startup resource, and The virtual screen area displays the application interface of the current application to be preloaded, so as to realize the simulation start of the current application to be preloaded. When an abnormality is detected during the preloading process, processing the abnormality includes processing the abnormality when an abnormality is detected during the simulation startup process. This setting can simulate the startup process of the application to be preloaded outside the coordinate range of the display screen. This process is invisible to the user, will not interfere with the user's use, and can be timely and accurate during the simulation startup process. To find anomalies.

In some embodiments, when an abnormality is detected during the simulation startup process, processing the abnormality includes: determining a crash cause when an application crash occurs during the simulation startup process; according to The crash cause is repaired, and the application to be preloaded is simulated and started again. This setting reduces the probability that a pre-loaded, pre-loaded application will crash when it actually starts. In the process of using the terminal, the user may encounter a crash when the application starts or is running. The specific performance may be that the application crashes, that is, closes quickly. Generally, the application cannot be processed when it is started or running. The behavior of exiting the application from time to time due to an exception or error, the user can only restart the application. There are many reasons for the crash, for example, too much cache garbage; too many programs running, causing insufficient memory; application version compatibility issues; when accessing the network, ImageView in the component is not downloaded and displayed on the application page normally; application The corresponding Software Development Kit (SDK) is not compatible with the system version of the terminal, etc .; some are related to the current network status or memory card and other factors. Some causes of application crashes can be detected or analyzed, and further measures can be taken to address the cause of the crash to eliminate the impact of the crash on the application's operation.

In some embodiments, the cause of the crash includes insufficient storage space. The performing repair processing according to the cause of the crash includes: clearing cache data and / or closing a preset type of application running in the background. When the cache data in the terminal has not been cleaned for a long time and a large number of cache garbage files are accumulated, the cache data will occupy more system storage space, which will not only affect the smooth running of the system, but also cause the application to crash. When there are many applications running in the background in the terminal, it will also take up more system memory, which will also easily cause the application to crash. During the simulated startup process of the application to be preloaded, if the crash of the application is detected due to insufficient storage space, the cache data can be cleared, or the preset type of application running in the background can be closed, or cleaned up at the same time Cache data and close preset types of applications running in the background. Among them, the preset type of application can be set by the system by default or set by the user. For example, a preset application list may be maintained in the terminal, and the applications in the preset application list may be considered as preset types of applications, and the applications in the preset application list may generally be used infrequently by the user or not. For important applications, when it is necessary to repair the cause of the crash, you can determine whether the current background running application is in the preset application list. If it exists, you can close the application. If the current background running application is Multiple, you can make a judgment in sequence and determine whether to close according to the judgment result.

In some embodiments, a level may be set for the cached data, and the cached data of the corresponding level is selected for cleaning according to the severity of the application crash situation during the simulated startup process. Exemplarily, the cache data may be set to include a first-level cache, a second-level cache, and a third-level cache. The third-level cache includes cached data in a local database, and the second-level cache includes cached data in a temporary directory. The first level of cache includes cached data in the Document directory. In the case of an application crash for the first time during the simulation startup, clear the third-level cache data; after clearing the third-level cache data, re-treat the preloaded application for simulated startup, and if the crash occurs again, clear the second Level cache data; after clearing the second level cache data, simulate the startup of the preloaded application again, and if a third crash occurs, clear the third level cache data. The above is only a schematic description. More levels can be set for the cache data, and the correspondence between the number of crashes and the cache level that needs to be cleared can be freely set.

In some embodiments, the simulating startup of the current to-be-loaded application program outside the coordinate range of the display screen includes: based on a pre-created pre-loaded active window stack, corresponding to the to-be-loaded application program. The application interface performs drawing and display, wherein the boundary coordinates corresponding to the preloaded active window stack are outside the coordinate range of the display screen. This setting can draw and display the application interface, simulate the process of the application from startup to display the application interface, and at the same time perform the simulation startup more comprehensively, it can also complete the preparation work before the application startup to a greater extent, and improve the waiting time. The startup speed of the loaded application does not affect the display of the display content of the foreground application on the display screen.

In the embodiment of the present application, the active window may be understood as an independent interface that directly provides users with interaction and operation, and different terms may be used to name the interface in different operating systems. In order to facilitate understanding, the following description is made by taking an Android operating system as an example.

In the Android system, the active window is called Activity. Activity is a component responsible for interacting with the user. It provides a screen (which can be understood as a screen interface instead of a physical display screen) for the user to interactively complete a certain task. In an android application, an Activity is usually a separate screen, which can display some controls or listen to and handle user events. In the management of Activity, there are two concepts: Task (task stack) and Stack (active window stack). A Task corresponds to an application. A Task is used to store Activities. A Task can store one or more Activities, and these Activities follow the "first in, first out, last in, first out" principle. Stack is also used to manage Tasks. Generally, a Stack manages the Tasks that each Activity needs to display on a screen. A Stack can manage one or more Tasks. Of course, Stack also follows the basic management principles of the Stack. . The screens described here are not necessarily complete and independent display screens. Taking "two screens" as an example, these two screens may be just two areas in a complete display screen that independently display their respective display contents. Of course, if the terminal has two or more independent display screens, the "two screens" may also be two independent display screens.

In the Android system, multi-window mode is supported, which can include split-screen mode, picture-in-picture mode, and FreeForm. In the multi-window mode, the stack where the application is located can have its own size, which can include the 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) generally describes a rectangular boundary, which can be expressed by the coordinates of the upper left corner and the lower right corner of the rectangle, that is, the upper left corner of the rectangle is (a, b), right The lower corner coordinate is (c, d), and such a rectangular area corresponds to the size of the Stack. The layout of the application in the stack is based on the size of the stack, which means that the application interface corresponding to the activity is displayed within the boundary of the size.

In multi-window mode, you can allow multiple applications to be visible, including both system and user visible and system only visible. Both visible to the system and the user means to be displayed on the display screen and can be seen by the user; only visible to the system means that the operating system is visible and the user is not visible, which may be obscured by the application in the foreground or as implemented in this application Show off screen.

In the embodiment of the present application, pre-loading the application interface of the target application program outside the display screen can be implemented based on the multi-window mechanism of the operating system, and the size corresponding to the application program is set outside the display screen through the multi-window mechanism to the user. It is not visible, so it will not affect the display content of the foreground application on the display screen.

Generally, in multi-window mode, there can be multiple types of stacks. For example, Home Stack represents the stack displayed by desktop applications, App Stack represents the stack displayed by third-party applications, and there can be other split-screen stacks. The contained content can be displayed on a display screen, which is collectively referred to as an application active window stack in the embodiments of the present application. In the embodiment of the present application, a preloaded active window stack (preloaded stack) is added to indicate the stack displayed by the preloaded application, and the boundary coordinates of the preloaded stack are set outside the coordinate range of the display screen, and are to be preloaded The application can be displayed on that Stack. For the Android system, based on the multi-window mechanism of the Android system, a new Stack dedicated to displaying preloaded applications can be created. In the embodiment of the present application, a new stack is created because the newly created preloaded stack can have its own size and visibility, thereby achieving preloading and simulation startup outside the display screen.

In the embodiment of the present application, the creation timing of the preloaded stack is not limited. The preloaded stack can be set to the resident state by default before the terminal leaves the factory, that is, the preloaded stack always exists; or the terminal can be successfully unlocked when the terminal is powered on Create later; you can also create after the application preload event is triggered (before you determine the application to be preloaded) and so on. In an embodiment, the drawing and displaying the application interface corresponding to the application to be preloaded based on the pre-created preloaded active window stack includes: determining whether a pre-created preloaded active window stack exists; if If it does not exist, a preloaded active window stack is created according to a preset rule; and the application interface corresponding to the application to be preloaded is drawn and displayed based on the preloaded active window stack created. This setting can determine whether the pre-loaded stack exists after determining the application to be pre-loaded. If it exists, you do not need to create a new stack. If it does not exist, create it, which can save system resources. It can be understood that when there are multiple applications to be preloaded, that is, when multiple applications need to be preloaded continuously in a short period of time, the preloading stack has been created before the first application to be preloaded starts to load. After that, the pre-loading stack exists before the second application to be pre-loaded starts to be loaded, and the above judgment may not be necessary.

In some embodiments, the drawing and displaying an application interface corresponding to the application to be preloaded based on a pre-created preloading active window stack includes: creating a target process corresponding to the application to be preloaded; Creating a task stack corresponding to the application to be preloaded in a pre-created preloading active window stack; starting an active window corresponding to the application to be preloaded in the task stack based on the target process; based on the launched The active window draws and displays an application interface corresponding to the application to be preloaded. The application interface may include a startup interface of an application program and / or a startup animation (such as a startup advertisement). When the target process is created, the initialization process of the target process can also be included. During the execution of the above steps, pre-loading of other resources may also be involved, such as application service startup, memory allocation, file content reading, and network data acquisition. The embodiments of this application do not limit the pre-loading process of other resources. Can be determined by the characteristics of the application to be preloaded. The above steps describe the preloading process of the application to be preloaded, and during the execution of the above preloading-related steps, the simulated startup of the application to be preloaded is also implemented.

In some embodiments, the method further includes: sending a fake focus notification to the application to be preloaded, and maintaining a continuous drawing of an application interface corresponding to the application to be preloaded for a preset period of time based on the fake focus notification. And display updates. This setting can complete the drawing and display of the application interface when the application to be preloaded has the focus and is visible to the system, improving the completion of the preloading without affecting the focus of the foreground application. The focus in the embodiments of the present application is also referred to as input focus, and the fake focus and the focus corresponding to the foreground application are independent of each other. Generally, for the current Android system, the focus is unique. For example, input operations such as touch only take effect on the focus. For the input of focus information, the system and the application are consistent. Once the system changes the input focus information, it will Send information to the application that the input focus information has changed, this way to ensure that the system and application side input focus information is consistent. In the embodiment of the present application, the application side can forge the focus by separating the system side and the application side from inputting focus information. In the embodiment of the present application, the focus notification for the preloaded application is forged, so that the preloaded application has focus information, and the focus information on the system side is still correct. The application to be preloaded can keep the interface updated for a certain period of time after the simulation startup time, which is convenient to accurately locate the abnormal situation. The focus exists on the system side and the application side. It can be considered as the server and the client. The system side records the application that has the focus, and the application side saves a flag to indicate whether it has focus. The timing of falsifying the input focus may be that when the Android window system adds a new window and the focus needs to be updated, a fake focus notification is generated and sent. The method of falsifying the focus may be a method of calling the client side of the window to change the focus of the window, so that the window acquires focus. In one embodiment, a fake focus notification can be sent based on the Binder mechanism. The Binder mechanism is the most commonly used method for inter-process communication of the Android system, and adopts a c / s architecture, that is, a client / service architecture.

In the embodiment of the present application, the preset time period may be designed according to actual conditions, for example, it may be within a fixed time range after starting preloading, or it may be a period from starting preloading to completing preloading. In some embodiments, the length of the preset time period includes a playing time of starting an advertisement or starting an animation in the target application. During the startup of some applications, some advertisements or animations are usually played. The duration of advertisements or animations usually ranges from 3 seconds to more than ten seconds. During the playback of advertisements or animations, the user may not be able to perform any operation, only Can wait for the playback to finish, wasting valuable time of the user. This embodiment of the present application is set up so that the startup advertisement or startup animation can be played off the screen before the application to be preloaded is launched. When the application to be preloaded is launched, it can directly enter the main page of the application or other user-operable Interface to further advance the operable time point of the application to be preloaded and reduce waiting time. In addition, during the process of playing startup ads or starting animations, application crashes or other abnormalities may also occur, and the preloading process can be more fully monitored.

In some embodiments, after drawing and displaying an application interface corresponding to the application to be preloaded based on a pre-created preloading active window stack, the method further includes: upon receiving the When the target application runs, the application interface corresponding to the target application included in the preloaded active window stack is migrated to the display screen for display. This setting can directly migrate the already drawn application interface to the display screen for display when the target application really needs to be started, which can achieve fast switching of the application interface and improve startup speed.

In some embodiments, the migrating an application interface corresponding to the target application included in the preloaded active window stack to the display screen for display includes: The task stack corresponding to the target application is migrated to the top of the application active window stack; the size information, configuration information, and visibility of the task stack are updated to implement the application interface corresponding to the target application on the display screen display. This setting can ensure the stability of the interface migration process, and ensure that there are no screens, black screens, or slow migration speeds during the recovery process.

For some terminals, especially mobile terminals such as mobile phones and tablet computers, in order to facilitate the use of the user, the display mode of the display screen usually includes vertical screen display and horizontal screen display. Many applications use vertical screen display by default, and some The application program is displayed in a horizontal screen mode (such as some online games) by default. During the use of the terminal, some applications may switch between the horizontal and vertical screen display as the user holds 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, and an origin of the system coordinate is In the upper left corner of the display screen, H is the length of the long side of the display area of the display screen. That is, the side corresponding to H is the largest side of the display area of the display screen, which is the height of the display screen when displayed in the vertical screen and the width of the display screen when displayed in the horizontal screen. This setting takes into consideration the display screen landscape, pre-loaded application landscape display, and some applications' normal display. FIG. 2 is a schematic diagram of a relative position relationship between a preloaded active window stack and a display screen display area according to an embodiment of the present application. As shown in FIG. 2, the display screen is in the 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, and the height direction is the Y axis. The boundary coordinates corresponding to loading Stack202 are (H, 0, 2H, H), where H is the screen height, that is, the area within the solid rectangle on the left is the main screen display area, and the area within the rectangle on the right dashed line is the preload display area. FIG. 3 is a schematic diagram of a relative position relationship between another preloaded active window stack and a display screen display area according to an embodiment of the present application. As shown in Figure 3, the display screen is in 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, and the width direction is the Y axis. The boundary coordinates corresponding to loading Stack202 are (H, 0, 2H, H), where H is the screen height, that is, the area within the solid rectangle on the left is the main screen display area, and the area within the rectangle on the right dashed line is the preload display area.

The reason for pre-loading the stack boundaries is as follows:

The horizontal axis of the upper left corner is H, which is to prevent the display screen (also called the home screen) from being displayed on the pre-loaded application interface when the screen is horizontal, because the home screen has a horizontal screen mode in addition to the vertical screen mode. In order to prevent part of the preloaded application from being displayed in the main screen display area, the horizontal coordinate of the upper left corner of the rectangular area corresponding to the preloaded stack is set to the screen height.

The vertical coordinate of the upper left corner is 0, so that the preloaded application can correctly calculate the height of the status bar. In order to better design the user interface (UI), the Android application will customize the top status bar. If the corresponding vertical coordinate is not equal to 0, the height of the status bar may be wrong.

The horizontal axis of the lower right corner is 2H (2 times the screen height), that is, the width of the rectangle corresponding to the preloaded stack = screen height, so that the size of the preloaded stack can include the horizontal screen application when preloaded (that is, the application interface is horizontal screen) Display mode application).

The vertical coordinate of the lower right corner is H, that is, the height of the rectangle corresponding to the pre-loaded Stack = screen height, so that the size of the pre-loaded Stack can include the vertical screen application when pre-loaded.

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

In addition, FIG. 4 is a schematic diagram of an application interface migration provided by an embodiment of the present application. As shown in FIG. 4, upon receiving a running instruction of a target application, an application corresponding to the target application included in the active window stack is preloaded. The interface 401 is migrated to the display screen 201 for display. In one embodiment, the task to which the preloaded application interface belongs is migrated to the top of the application activity window Stack, and the size information, configuration information, and visibility of the task are updated to thereby apply the interface. Able to display normally on the display screen.

In some embodiments, when an abnormality is detected during the simulation startup process, processing the abnormality includes: detecting that the application to be preloaded is detected based on a pre-created preloaded active window stack. During the process of drawing and displaying the application interface corresponding to the program, if the current application interface is abnormally displayed, the current application interface is redrawn and displayed. This setting can further monitor the preloading from the perspective of the application interface. Exemplarily, the display exception may include at least one of a loading failure on the interface, a failure to obtain network data, a missing element, and a script error. Generally, the startup interface or startup animation when an application starts usually contains data that is dynamically updated on the network side, and the interface needs to be loaded and displayed according to the data obtained from the network side. During this process, various reasons may occur The page is displayed abnormally. For example, a monitoring file may be built in the terminal, and loading information of each application interface of the installed application program in the mobile terminal may be determined in advance, and the monitoring file may be written into the monitoring file. The interface displays whether an abnormality occurs for real-time detection. Exemplarily, it can also cooperate with a monitoring platform to implement detection of interface anomalies. For example, during the process of drawing and displaying the application interface, a monitoring request is sent to the monitoring platform, and the monitoring request is used to instruct the monitoring platform to detect the loading component of the pre-loaded application program, and feedback the element detection information to the terminal. The element detection information may include a schema (schema) and a document object model (dom) monitoring element. The monitoring platform can store the element detection information of the components to be preloaded by the application to be preloaded. For the loaded components contained in the application to be preloaded, deploy the corresponding monitoring points and the schema for monitoring. Language path) to obtain the corresponding dom monitoring element, and store the schema and dom monitoring elements as element detection information. The terminal can activate the pre-injected monitoring file in the preset application, and use the monitoring file and the received element detection information to perform anomaly detection on the page loading process. The abnormality detection may include interface loading failure detection, network data acquisition failure detection, element missing detection, and script (such as javascript) error detection. In the embodiment of the present application, when an abnormal display of the interface is detected, redrawing and displaying the current application interface can increase the probability that the application interface is normally displayed, so that when the pre-loaded application program is actually started, the application interface Can display normally.

In some embodiments, before the drawing and displaying the application interface corresponding to the application to be preloaded based on the pre-created preloading active window stack, the method further includes predicting that the application to be preloaded contains The target interface, wherein the target interface includes an interface that is predicted to be opened by a user according to a historical running rule of the application to be preloaded. The drawing and displaying the application interface corresponding to the to-be-loaded application program based on the pre-created pre-loading active window stack includes: corresponding to the to-be-loaded application program based on the pre-created pre-loading active window stack. The target interface is drawn and displayed. This setting can predict the interface that the user is about to open, and preload the interface. On the basis of increasing the application startup speed, the interface opening speed is further increased. At the same time, it can be determined in advance whether an exception will occur during the opening of the target interface. The display of the target interface is abnormal during the simulation startup phase. The target interface can be redrawn and displayed to reduce the probability of the display abnormality when the user actually opens the target interface. In the embodiment of the present application, the number of target interfaces is not limited, and may include one or more. In the process of using the application, users usually have their own habits and operate the application according to their own habits, so that the application will show certain operating rules under the user's operation, such as opening each interface Sequence or frequency, the length of time spent on each interface, etc., can collect data related to the above operating rules (such as the log information corresponding to the application program), statistics or analyze the historical operating rules of the application program, when you need to predict the target interface, according to the The historical running rule corresponding to the application predicts the interface that will be opened by the user. In addition, the target interface can be predicted based on the current usage scenario. After pre-loading the target interface, if the user chooses to launch an application that has been pre-loaded, the application will be launched based on the pre-loaded startup resources. When the target interface needs to be opened, the pre-loaded interface can be used. Resources quickly open the target interface and increase the speed of opening the target interface. Exemplarily, predicting the target interface included in the application to be preloaded may include: according to the order in which each interface included is opened, the frequency of opening, or the stay during the running process of the application to be preloaded in the historical sampling period. Duration, predicts the target interface contained in the application to be preloaded. Exemplarily, the historical sampling period may include a time period obtained after tracing a preset duration from the current moment forward. For example, 30 days forward from today, the length of the historical sampling period is 1 month; and another 24 hours forward from 9 am, the length of the historical sampling period is 1 day. In addition, the historical sampling period can also be a fixed period, for example, from the 1st of each month to the end of the current month, or from 0 to 24 o'clock every day. For an application, there may be multiple functions, and each interface may include multiple interfaces. Take WeChat as an example, including chat list interface, chat interface, address book interface, circle of friends interface, scan interface, shake Shake interface and wallet interface. In the process of using the application program by the user, the terminal can record the running rule of the application program under the user's operation. Exemplarily, the order in which each interface is opened may include the first interface, the second interface that is opened under the user's operation after the application is started, ... the Nth interface, which forms a sequence of opening sequences, among which the first interface It is not the startup interface that is opened by default when the application starts, but an interface that requires the user to actively open it. The same interface can be ignored after being opened for the first time, that is, it is not included in the opening sequence. The frequency with which an interface is opened may include the total number of times that the interface was opened during the historical sampling period, or the number of times that the interface was opened within a unit time period (for example, 5 minutes) during the historical sampling period. The dwell time of an interface may include the length of time that the interface is continuously displayed on the display screen. During the display, the user can view the content of the interface or slide the interface. Generally, the higher the opening order, the higher the opening frequency, or the longer the dwell time, the higher the probability that the corresponding interface becomes the target interface. According to this rule, you can comprehensively score each interface included in the application. , To obtain the probability that each interface becomes the target interface, and then determine one or more interfaces with a higher probability as the target interface.

Exemplarily, predicting the target interface included in the application to be preloaded may also include: obtaining current usage scenario information, and predicting the target interface included in the application to be preloaded according to the current usage scenario information. Exemplarily, the use scene information may include, for example, the location of the terminal, the operating status of the terminal (such as the on / off status of the mobile data network, the connection status of the wireless hotspot, the identity information of the connected wireless hotspot, and the plugging state of the headset jack , Charging status, battery power information, and screen display time, etc.), data collected by sensors integrated in the terminal (such as motion sensors, light sensors, temperature sensors, and humidity sensors) and so on. This setting can predict the target interface more accurately.

Exemplarily, before detecting that the application preloading event is triggered, before determining the application to be preloaded, the method further includes: during the application running process, when an interface switch occurs, collecting and using scene information as training For the sample, the switched interface is recorded as a sample mark corresponding to the training sample, and a preset machine learning model is trained according to the training sample and the corresponding sample mark to obtain an interface prediction model. The predicting a target interface included in the application to be preloaded according to the current usage scenario information includes inputting the current usage scenario information into the interface prediction model, and determining based on an output result of the interface prediction model.

When the target interface prediction is required, the prediction is performed based on the output of the prediction model. The prediction speed is fast and the result accuracy is high.

In an embodiment, the target interface can also be comprehensively determined in combination with the order in which each interface included is opened, the frequency or duration of stay, and the current usage scenario information during the running of the application to be preloaded in the historical sampling period. To further improve prediction accuracy. In addition, the order in which each interface is opened, the frequency of opening, or the length of stay can be used as part of the training sample and added to the above training sample containing the use scene information to train the preset machine learning model to obtain the interface prediction model.

This setting can more comprehensively perform anomaly detection on the preloading process.

FIG. 5 is a schematic flowchart of another application preloading method according to an embodiment of the present application. The method includes steps 501 to 506.

In step 501, when it is detected that an application preload event is triggered, an application program to be preloaded is determined.

In step 502, the application to be preloaded is simulated and started outside the coordinate range of the display screen.

In step 503, the simulation startup process is monitored to determine whether an application crash occurs. Based on the judgment result of the application crash, step 504 is performed; based on the judgment result of no application crash, the step 506 is performed.

In step 504, the cause of the crash is determined, and repair processing is performed according to the cause of the crash.

For example, if the cause of the crash is insufficient storage space, you can clear the cache data and close the preset type of application running in the background; if the cause of the crash is an application version compatibility issue, you can perform an automatic version upgrade of the application or prompt the user whether to proceed Version upgrade; if the cause of the crash is related to the current network condition or memory card, the user can be prompted to check the network status or memory card status.

In step 505, the application to be preloaded is simulated and started outside the coordinate range of the display screen again.

In step 506, when a run instruction of the target application in the application to be preloaded is received, the target application is started based on the preloaded resources of the target application.

In the embodiment of the present application, the triggering condition of the application preload event may be detecting a change in the foreground application program.

In step 602, a predetermined number of candidate application programs with a higher startup probability are determined as the application programs to be preloaded.

In step 603, for the current application to be preloaded, the target interface is predicted, a corresponding target process is created, a corresponding task stack is created in the preloaded active window stack, and a corresponding active window is started in the task stack based on the target process.

In step 604, a target interface is drawn and displayed based on the activated active window.

In step 605, it is determined whether the display of the target interface is abnormal, and based on the determination result of the display of the target interface, step 606 is performed; based on the determination of the display of the target interface, the display is abnormal, step 607 is performed.

In step 606, the target interface is drawn and displayed again based on the activated active window.

Exemplarily, the display exception may include at least one of a loading failure on the interface, a failure to obtain network data, a missing element, and a script error. After redrawing and displaying the target interface, the above display abnormalities may no longer appear, because during the interface drawing process, the above abnormalities may be affected by various factors such as the network. When redrawing, it may cause the previous The cause of the secondary anomaly has disappeared.

For example, after the target interface is drawn and displayed again, further detection may be performed. If the display abnormality still occurs, the third drawing and display may be performed. The application does not limit the number of detections and the number of repeated drawing and display. Set freely according to the actual situation.

Suppose the predicted applications to be preloaded include WeChat, Today's Headline, Alipay and Baidu Maps. The first pre-loaded application was WeChat, followed by Today's Headline, Alipay, and Baidu Map. For example, the current application to be preloaded in step 603 is WeChat, and the target interface corresponding to WeChat is the circle of friends interface. In step 605, it is determined whether the circle of friends interface displays abnormality. If it appears, redraw and display it. , You can use today ’s headline as the new current application to be preloaded, repeat step 603, and so on, and then preload Alipay and Baidu maps.

For example, in step 607, if the user clicks the application icon of Alipay, the terminal will receive the Alipay operation instruction. At this time, the pre-loaded Alipay target interface (such as Ant Forest) can be removed from the pre-loaded active window. The stack is migrated to the display screen for display. When Alipay is quickly launched, it also directly opens the predicted user's upcoming interface, which saves the user from opening the target interface. In addition, it can also ensure the success rate of the target interface's normal display.

The application preloading method provided by the embodiment of the present application uses a prediction model to predict an application to be preloaded to be started when a foreground application changes, and predicts a target interface to be opened by a user in the application to be preloaded. In the invisible state, the target interface is drawn and displayed in advance based on the off-screen preloaded Stack, and display anomalies are detected in real time. When an abnormal display is found, the target interface is redrawn and displayed, and the user is preloaded when the user actually starts When using an application, it can improve the startup speed of the application and directly enter the target interface, and also ensure the success rate of the target interface's normal display.
