Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and in particular to a method for starting an application (App) and an electronic device. BACKGROUND

[0002] The starting time of an application in an electronic device is usually the time taken from when a user clicks on the application to when the screen of the electronic device displays the application opening. The shorter the starting time, the better the user experience.

[0003] Currently, there are two methods for shortening the starting time of an application: one method is to perform parallel loading during the starting process of the application; and the other method is for the electronic device to create an empty process in advance, so that the process created in advance can be used directly after the application is started, thereby reducing the time taken to create the process and achieving the purpose of shortening the starting time.

[0004] However, the above two methods have limited effect on shortening the starting time. SUMMARY

[0005] The embodiments of the present application provide a method for starting an application and an electronic device to further shorten the starting time of the application and improve the user experience.

[0006] In a first aspect, the embodiments of the present application provide a method for starting an application, applied to an electronic device, the electronic device being installed with a first application, and the method comprising: determining a starting time according to historical operation events of the user on the first application; and triggering execution of starting the first application to a first stage at the starting time before receiving a cold start operation of the user on the first application, the first stage being a framework initialization stage, a component starting stage, a window creation stage, or a first frame drawing stage before a display window.

[0007] Based on the above technical solution, compared with the prior art of preloading the first application to a stage deeper than the process creation stage, the starting time of the application experienced by the user can be further shortened, the starting performance is optimized, and the user experience is improved. Further, the method provided by the embodiments of the present application improves the intelligence of starting the application by determining the starting time according to the historical operation events of the user on the first application.

[0008] In a possible implementation manner, the system resources required for starting the first application are greater than a threshold value, so that the user experience can be further improved.

[0009] In a possible implementation manner, the starting of the first application to the first stage can comprise:

[0010] According to the configuration of the first application program, it is determined that the first application program declares a preloading stage as a framework initialization stage, a component startup stage, a window creation stage, or a first frame drawing stage;

[0011] The first application program is started to the framework initialization stage, the component startup stage, the window creation stage, or the first frame drawing stage.

[0012] Based on the above technical solution, the first application program can specify the preloading stage according to its own needs, further effectively shortening the startup time of the application program and improving the user experience.

[0013] In a possible implementation, before starting the first application program to the first stage, the method further includes: determining whether there is a permission to preload the first application program.

[0014] When there is a permission to preload the first application program, the first application program is started to the first stage.

[0015] Based on the above technical solution, the method provided by the embodiments of the present application provides security protection for the method of starting the application program by determining the preloading permission.

[0016] In a possible implementation, during the process of starting the first application program to the first stage, any one or more of the sound, vibration, and display of the first application program can be shielded. For example, for some game application programs running on a mobile phone or a tablet, even if the user sets the game to be silent, the game will still occupy the focus of the sound when the game is running, which may affect the current business of the mobile phone, such as music playing. In this regard, the method provided by the present application can avoid the situation that the application program occupies the focus of the sound during the startup process. Similarly, the method provided by the present application can also avoid the situation that the application program generates vibration, displays game notifications, or causes screen flickering during the startup process.

[0017] Based on the above technical solution, the method provided by the embodiments of the present application avoids interference with the user by shielding any one or more of the sound, vibration, and display, which are user-perceptible behaviors, and improves the user's experience of the cold start performance of the application program.

[0018] In a possible implementation, shielding any one or more of the sound, vibration, and display of the first application program can include that the system of the electronic device shields any one or more of the sound, vibration, and display of the first application program.

[0019] Based on the above technical solution, the method provided by the embodiments of the present application provides shielding protection by shielding the user-perceptible behaviors during the preloading process of the application program.

[0020] In a possible implementation, the shielding of any one or more of sound, vibration and display of the first application can include shielding of any one or more of sound, vibration and display of the first application by the first application itself.

[0021] Based on the technical solution, the method provided in the embodiments of the present application shields the user-perceptible behavior in the application preloading process by the application, the application can be self-adapted, and the performance of the application is improved.

[0022] In a possible implementation, after the first application is started to the first stage, the method can further include:

[0023] continuing to start the first application from the first stage in response to a cold start operation of the first application by the user.

[0024] Based on the technical solution, the method provided in the embodiments of the present application preloads the application to the first stage, and continues to start based on the process of the first stage after the cold start operation of the application by the user, thereby improving the experience of the cold start operation of the application by the user.

[0025] In a possible implementation, after the first application is started to the first stage, the method can further include freezing the process of the first application in the first stage.

[0026] Based on the technical solution, the method provided in the embodiments of the present application freezes the application process in the first stage, so that the CPU, memory and other resources can be released, and the system performance of the electronic device is optimized.

[0027] In a possible implementation, after the process of the application in the first stage is frozen, the method can further include:

[0028] unfreezing the process of the application in the first stage in response to a cold start operation of the first application by the user, and continuing to start the first application from the first stage;

[0029] displaying an interface of the first application.

[0030] Based on the technical solution, the method provided in the embodiments of the present application unfreezes the process of the first stage after the cold start operation of the application by the user, and continues to start the first application, thereby shortening the start time of the application perceived by the user while optimizing the performance of the electronic device, and further improving the experience of the user.

[0031] In a possible implementation, after the interface of the first application is displayed, the method can further include closing the first application in response to a quit operation of the first application by the user.

[0032] Start the first application to a first stage.

[0033] Based on the above technical solution, the method provided by the embodiment of the present application is more intelligent.

[0034] In a possible implementation, after displaying the interface of the first application, the method further includes:

[0035] Retiring the first application to the background;

[0036] When the first application is killed in the background, starting the first application to the first stage.

[0037] Based on the above technical solution, the method provided by the embodiment of the present application can be applied to more scenarios.

[0039] Based on the above technical solution, the method provided by the embodiment of the present application shortens the start time of the second application experienced by the user by using a similar method to start the first application, which helps to improve the user's experience of the overall performance of the electronic device.

[0040] In a possible implementation, the second stage can be different from the first stage.

[0103] It should be noted that, Figure 2 As an example of the software structure of an electronic device, only some levels and software modules are simply listed, and do not constitute any limitation on the software structure of the electronic device. In actual applications, the operating system of the electronic device can also include other levels, or each level can also include other software modules for implementing one or more functions or services. In addition, the embodiments of the present application do not limit the specific level where each software module is located. For example, some system services in the system service layer can be deployed in the application program framework layer or in the kernel layer.

[0104] By way of example, any of the electronic devices in the above embodiments can be installed with one or more application programs, and a user can start an application program by clicking on the icon of the application program displayed on the above display screen. Cold start of an application program refers to the start of the application program from the creation of a new process. The cold start time is an important indicator of the performance of the application program, and as the first "gate" of user experience, directly determines the first impression of the user on the application program.

[0105] The first existing method optimizes the cold start of the application program by parallelizing the loading during the start-up process of the application program. For example, some operating systems start some tasks in parallel during the start-up process of the application program. However, this method can only start to optimize after the user performs a cold start operation on the application program (such as clicking on the icon of the application program), and the optimization performance is limited.

[0106] For example, For example, Figure 3As shown, before the system responds to the user's operation of clicking the icon of the application program and starts the application program, and before the application program is completely started, the developer can start the multi-thread in the T1 and T2 stages to perform some parallel tasks, so as to improve the starting speed of the application program. However, the effect of this method in accelerating the starting is limited. If the application process can be started in the background and the resources can be prepared before the user clicks the icon of the application program, the starting performance of the application program can be greatly optimized when the application program is really started.

[0107] The second method is to The operating system creates an empty process in advance through the mechanism of an unspecialized application process (USAP). When the application program is loaded in response to the user's starting operation, an empty process in the process pool created in advance is used. For example, the zygote process creates a usap pool in advance by calling the fork system, and the usap pool has 10 processes usap1-usap10 for use by the application program. Figure 4 As shown, the zygote process creates a usap pool in advance by calling the fork system, and the usap pool has 10 processes usap1-usap10 for use by the application program. However, this method can only save the time of creating a process by fork, and the benefit is limited, and the starting performance cannot be further improved.

[0108] To further improve the starting performance of the application program, an embodiment of the present application provides a method for starting an application program, which can be applied to any electronic device provided in the above embodiments. The electronic device using the method for starting an application program can be installed with a first application program, and the method can include: starting the first application program to a first stage before receiving a user's operation on the first application program, the first stage being any stage between creating a process and displaying a window, and the operation being used to start the first application program (for the user, the operation is a cold starting operation). The method provided in the embodiment can further shorten the starting time of the application program and optimize the starting performance and improve the user experience compared with the prior art.

[0109] In some embodiments, the first application can be an application whose system resources required to be loaded when starting are greater than a threshold value. For example, a game application, a drawing application, an image processing application, and the like, which require loading of a large amount of memory, CPU, and the like system resources when starting, when the system resources required are greater than the threshold value, the method for starting the application provided by the embodiments of the present application can more effectively reduce the starting time, further improving the user experience. In this way, for some heavy applications in actual use scenarios which have a long time-consuming in the starting process (such as opening of a large file, etc.), the application can be preloaded to a very deep stage (such as the large file has been opened, the content has been drawn, only not displayed), which can complete most of the starting tasks of the application before the user clicks the icon of the application, so that the user feels cold start when starting the application and experiences faster starting speed, thereby further improving the user experience. For ease of description, the operation of starting the first application to the first stage before receiving the cold start operation of the first application by the user is referred to as preloading the first application. Exemplarily, the cold start operation of the first application by the user can be that the user clicks the icon of the first application displayed on the display screen.

[0110] In some embodiments, whether the system resources required to be loaded by the first application when starting exceed a threshold value can be determined by the developer of the first application to determine whether to use the method for starting the application provided by the embodiments of the present application. In some embodiments, whether the system resources required to be loaded by the first application when starting exceed a threshold value can be determined by the system of the electronic device.

[0111] Exemplarily, the first stage can be a framework initialization stage, a component starting stage, a window creation stage, or a first frame drawing stage as shown in the framework, but is not limited thereto. Figure 5

[0112] In some embodiments, the first stage can also be a process creation stage.

[0113] Exemplarily, the operation that can be included in the process creation stage is: A daemon process zygote in the operating system creates a new process by calling the fork system; or exemplarily, the operation that can be included in the process creation stage is that a daemon process AppSpawn in HarmonyOS creates a new process by calling the fork, and the like.

[0114] Exemplarily, ​In the operating system, the operations that the framework initialization stage can include are: creating an app object; starting a main process ActivityThread; creating a MainActivity to provide a basic user interface and interaction function for the application; and the like. Among them, creating the MainActivity can include creating a MainActivity class, configuring an AndroidManifest.xml, creating a layout file, and starting a component (Activity), and the like.

[0115] Exemplarily, in the HarmonyOS, the operations that the framework initialization stage can include are: component container creation (AbilityStage Create), which can specifically include module initialization and configuration file association. Among them, the module initialization can be to perform module-level initialization operations in the onCreate method, such as loading resource files (such as preloading pictures, fonts, and the like), creating a background thread or processing module-level data preprocessing, reading system-level configuration information (such as device power, network status, and the like), and the like. The configuration file association can specify an entry file path in module.json5.

[0116] Exemplarily, In the operating system, the component startup stage can include starting an Activity, and the like.

[0117] Exemplarily, in the HarmonyOS, the component startup stage can include component creation (Ability Create), such as UI Ability Create. This stage can perform operations such as initializing global configurations, resource preloading, and registering system event listening.

[0118] Exemplarily, In the operating system, the window creation stage can include window token allocation, SurfaceControl and GraphicBuffer allocation, layout calculation and rendering, etc. The window token allocation can specifically be: the system allocates a window token (WindowToken) for the new Activity through the addWindow() method of WMS, and determines the window type (application window / dialog / system window). The SurfaceControl and GraphicBuffer allocation can specifically include: creating a SurfaceControl object for the window, and allocating a GraphicBuffer (graphic buffer) and a Layer object by SurfaceFlinger, etc. The layout calculation and rendering can specifically be: the ViewRootImpl completes measurement / layout / drawing through the performTraversals() method, generates a display list (DisplayList), and finally coordinates the rendering synthesis by Choreographer.

[0119] Exemplarily, in the HarmonyOS, the window creation stage can include loading page content and resource allocation. The loading page content can include: specifying the displayed page through the windowStage.loadContent method, and setting window properties (such as brightness, direction, etc.). The resource allocation can include: completing the initialization of window-related resources, which can specifically include view handle allocation and memory management.

[0120] Exemplarily, In the operating system, the first frame rendering stage can include: measurement (Measure), layout (Layout) and drawing (Draw), etc. The measurement can be: the system traverses the view hierarchy tree, calculates the size (width and height) of each view, and this stage is completed by calling the onMeasure() method. The layout can be: determining the view position according to the measurement result, and setting the specific coordinates of each view by recursively calling the onLayout() method. The drawing can be: executing the onDraw() method to draw the view to the screen. Exemplarily, the first frame rendering stage can also include: optimizing key points, such as loading components on demand, to reduce the number of views loaded in the first frame (such as using LazyForEach instead of ForEach to reduce the number of initialized elements), and reducing the custom component life cycle time, which can be specifically achieved by optimizing the initialization logic of the custom component to shorten the measurement and layout stage time.

[0121] For example, in HarmonyOS, the first frame rendering stage may include: loading the page, measurement and layout, and rendering. Loading the page may include initializing homepage UI elements, such as loading resources like lists and images. Measurement and layout may include calculating the positions of UI elements and generating layout information. Rendering specifically involves drawing the UI elements onto the screen.

[0122] An example of a method to launch an application is as follows: Figure 6 As shown, for electronic devices running HarmonyOS, before the user performs a startup operation on the first application installed on the electronic device (a cold start operation for the user), the system can start the first application at any stage before the `onForeground` callback method, meaning the preloading depth can be as deep as the window content is fully drawn. Thus, if the first stage is when the window content is fully drawn, when the user performs a cold start operation on the first application, the first application can directly call the `onForeground` callback method to switch the already drawn window content from the background to the foreground, achieving the fastest possible window display and maximizing user satisfaction with the cold start performance of the first application.

[0123] Another example of electronic device software architecture is... Figure 7 As shown, it includes component management service 710, startup control service 720, first application 730, and process control services SA1-SAn. Among them, component management service 710, startup control service 720, and process control services SA1-SAn all belong to the underlying system services.

[0124] In some examples, for some operating systems, system services can be system capabilities (SAs), etc.

[0125] In some examples, for some operating systems, component management services such as the Abilitymanager service (AMS) can be used to manage the startup, shutdown, preloading, etc. of application processes.

[0126] The startup control service 720 can be used to control the timing of application preloading by the component management service 710. For example, when the startup control service 720 determines that the conditions for application preloading are met (such as the current time reaching the preloading time), it calls (or instructs) the component management service 710 to preload the application. The first application 730 is an application installed in the electronic device.

[0127] In some embodiments, a plurality of applications can be installed in the electronic device, and different applications can be preloaded to different stages. The process control services SA1-SAn can perform active queries and listen to the preloading status of the application processes, and different services in the process control services SA1-SAn can perform operations such as freezing of the processes, perceptible shielding, and the like.

[0128] In some examples, the process control service SA1 can be, for example, a resource scheduling service (RSS). When the preloading is completed, the RSS can be used to freeze the processes.

[0129] In some examples, the process control service SA2 can be, for example, a media service (Media Service), which can be used to shield the sound that can be generated during the preloading.

[0130] In some examples, the process control service SA3 can be, for example, a vibrator service (Vibrator Service), which can be used to shield the vibration that can be generated during the preloading.

[0131] In some examples, the process control service SA4 can be, for example, a window manager service (Window Manager Service), which can be used to shield the display that can be generated during the preloading, and the like.

[0132] In some embodiments, the stages of preloading can be notified to the process control services SA1-SAn by the component management service 710. The freezing of the processes can refer to the behavior or operation of the system kernel no longer scheduling the application processes and not allocating CPU resources to the application processes.

[0133] In some embodiments, to obtain the preloading status of the first application by the process control services SA1-SAn, the process control services can first be registered with the component management service 710, and the component management service 710 can only notify the preloading status of the first application to the registered process control services.

[0134] In some embodiments, the startup control service 720 can also perceive the system memory pressure and control it, monitor the application, and learn the behavior habits of the user. The learning of the behavior habits of the user can be, for example, through file management to obtain the recently opened files of the user such as WPS, through a browser to obtain the recently downloaded information of the user, through an instant messaging (IM) application to obtain the recently received IM information of the user, through other devices of the same account to obtain the recently received information and the recently opened files, and / or through the user to obtain the function that is used most frequently, and the like. The learning of the behavior habits of the user by the startup control service 720 can also be the recently opened application of the user, the application that is used most frequently by the user, the application that is actively adapted, and the like.

[0135] In some embodiments, the system of the electronic device can determine the first stage according to the time consumption of the first application program to start up without acceleration measures, or the size of files to be loaded during the start-up of the first application program. For example, the longer the time consumption of the first application program to start up without acceleration measures, or the larger the size of files to be loaded during the start-up of the first application program, the closer the first stage is to the operation / phase of displaying the window.

[0136] In some embodiments, the application program installed in the electronic device can be pre-configured with a preloaded stage, for example, the first stage described above can be a stage specified in the configuration file of the application program. For example, in the method provided by the above embodiments, the starting of the first application program to the first stage can include the following steps as shown in the flowchart of FIG. 8: Figure 8

[0137] Step 801: According to the configuration of the first application program, it is determined that the first application program declares the first stage as a preloaded stage. For example, before preloading the first application program, the component management service 710 first reads the configuration file of the first application program to obtain the declaration of preloading to the first stage. In some embodiments, the component management service 710 can read the configuration file of the first application program when the start-up control service 720 instructs to pre-load the first application program.

[0138] Step 802: Start the first application program to the first stage, for example, the component management service 710 starts the first application program to the first stage.

[0139] In some embodiments, the start-up control service 720 can determine the time of preloading the first application program according to the user's behavior habits. Accordingly, before the above-mentioned starting of the first application program to the first stage, it further includes: determining the time of starting according to the historical operation events of the user on the first application program. At the time of starting, the above-mentioned starting of the first application program to the first stage is triggered to be executed.

[0140] For example, if the user usually opens the first application program at 9 p.m., the start-up control service 720 determines the preloading time (i.e. the time of starting the first application program) of the first application program to be 8:58 p.m. according to this habit. Or, for example, the user exits the first application program (backgrounds the first application program) due to the lag during the running of the first application program, and then usually starts the first application program again. The start-up control service 720 can determine that the first application program needs to be preloaded immediately after the user actively exits the first application program according to this behavior habit of the user, and so on.

[0141] ​In some embodiments, before the first application is started to the first stage, the method further comprises: determining whether there is a permission to preload the first application; and when there is a permission to preload the first application, performing the starting of the first application to the first stage. For example, when the component management service 710 receives a preload instruction from the launch control service 720, the component management service 710 first determines whether the launch control service 720 has the permission to preload the first application, and then performs the preload instruction of the launch control service 720 when the launch control service 720 has the permission to preload the first application.

[0142] In some embodiments, during the starting of the first application to the first stage, any one or more of sound, vibration, and display of the first application can be shielded to avoid interference with the user and improve the user's experience of the cold start performance of the first application. For example, the shielding of any one or more of sound, vibration, and display of the first application can be shielding of any one or more of sound, vibration, and display of the first application by the system of the electronic device.

[0143] In some embodiments, the first application 730 can be aware of the preload start and process it differently from the normal start, such as being aware of the start of the preload start through LaunchReason, and adapting to different stages or states of the preload to distinguish from the normal start, so that the user is unaware of the preload of the first application 730. For example, the shielding of any one or more of sound, vibration, and display of the first application can be shielding of any one or more of sound, vibration, and display of the first application by the first application itself.

[0144] In some embodiments, after the first application is started to the first stage, the method further comprises: receiving and responding to a cold start operation of the first application by the user, and continuing to start the first application from the first stage. In this case, the time from the cold start operation of the user (such as the user clicking on the icon of the first application) to the display window of the first application (i.e., the user seeing the first application open) is the time from the first stage to the display window. The closer the first stage is to the display window, the shorter the time from the user's clicking to seeing the first application open, and the better the user's experience.

[0145] In some embodiments, after the first application is started to the first stage, the method further includes freezing the application process in the first stage to suspend the process execution, releasing CPU, memory and other resources, improving the overall system operation efficiency and prolonging the endurance. For example, after the first application is preloaded to the first stage, the component management service 710 notifies the process control service SA1 to freeze the application process in the first stage.

[0146] In some embodiments, after the application process in the first stage is frozen, the method further includes, in response to a cold start operation of the first application by the user, unfreezing the application process in the first stage, continuing to start the first application from the first stage, and displaying an interface of the first application.

[0147] In some embodiments, after the interface of the first application is displayed, the method further includes, in response to a quit operation of the first application by the user, closing the first application, and starting the first application to the first stage. For example, the quit operation of the first application by the user can be due to a running lag of the first application. For example, after the cold start operation of the first application by the user, the first application is opened, and the electronic device displays the interface of the first application, and then the first application starts to run. When the first application runs and lags, the user exits the first application, and the start control service 720 can determine the historical operation event that the user exits and cold starts the first application again under the condition that the first application lags, and call the component management service 710 to preload the first application to the first stage before the cold start operation of the first application by the user again, so that the user experiences the fast opening of the first application after the cold start operation of the first application by the user again, and the user experience is improved. In some embodiments, the quit operation of the first application by the user can also be a misoperation, and the like.

[0148] In some embodiments, after the interface of the first application is displayed, the method further includes backing up the first application to the background, and starting the first application to the first stage when the first application is killed in the background. For example, backing up the first application to the background can be triggered by the operation of the user, or can be triggered by the system resource shortage or power management, and the like. When the first application is killed in the background, the first application can be preloaded, so that the user experiences the fast start after the cold start operation of the first application by the user, and the user experience of the electronic device and the first application is improved.

[0149] In some embodiments, the electronic device further installs a second application, and the method further includes: before receiving a cold start operation of the second application by the user, starting the second application to a second stage, the second stage being any stage between the process creation and the display window, such as the framework initialization stage, the component start stage, the window creation stage, or the first frame drawing stage before the display window. The principle and method are similar to the method of starting the first application provided in the above embodiments. For example, the second stage can be the same as the first stage, or can be different. For example, whether the first stage and the second stage are the same or not depends on the configuration of the first application and the second application.

[0150] The method of starting the application is another embodiment as shown in the figure. In this embodiment, the first application is a game App, and the preloading stage declared by the configuration of the game App is the window creation stage. The method of starting the game App includes: Figure 9

[0151] Step 901: RSS registers to listen to the state change of the game App. The RSS belongs to the process control service described above, and can be used to manage the resource scheduling of the App, such as freezing the process, allocating the CPU small core, etc.

[0152] Step 902: The AMS returns the registration result.

[0153] Step 903: The game SA calls the AMS to preload the game App. The calling time can refer to the time of determining the start described above. The game SA belongs to the start control service described above.

[0154] Step 904: The AMS queries the configuration of the game App from the bundle management service (BMS). The BMS can manage the installation, upgrade, and uninstallation of the application. When the electronic device installs the game App, the BMS can obtain the configuration file of the game App.

[0155] Step 905: The BMS returns the configuration of the game App, and the AMS obtains the preloading stage declared by the game App according to the configuration of the game App.

[0156] Step 906: The AMS determines whether the game App is started. If it is started, the next step continues to execute step 907, otherwise the next step continues to execute step 908.

[0157] Step 907: The AMS returns the result that the preloading is not executable to the game SA, and ends the preloading.

[0158] Step 908: The AMS determines to preload the game App to the window creation stage according to the preloading stage declared by the game App obtained from the configuration of the game App. ​

[0159] Step 909: The AMS notifies a window management module (SceneBoardManager, SCB) to start in silence. The SCB can be used to manage the creation and display of windows.

[0160] Step 910: The SCB returns a notification result to the AMS.

[0161] Step 911: The AMS returns a preloading state to the game SA.

[0162] Step 912: The SCB notifies the AMS that it has been pulled up in silence.

[0163] Step 913: The AMS pulls up the game App and drives to a window creation (OnWindowStageCreate) stage.

[0164] Step 914: The game App returns a preloading result to the AMS.

[0165] Step 915: The AMS notifies the RSS that the game App preloading is complete and the preloading stage is the window creation stage, so that the RSS freezes the game App process in the window creation stage.

[0166] In some embodiments, the game App can actively adapt to shield its sound, vibration or display during the process of being pulled up to the window creation stage.

[0167] In some embodiments, the AMS can also notify a system service for controlling sound, vibration or display to shield the sound, vibration or display of the game App in the preloading process, and other user-perceptible behaviors.

[0168] In some embodiments, step 906 can be performed before step 905.
