Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and in particular to a method for installing an application and an electronic device. BACKGROUND

[0002] When an electronic device installs an application (App), there are generally an upper-layer installation process and a lower-layer optimization process. For example, when the electronic device installs a plurality of Apps in batches or restores a plurality of Apps through cloning backup, the number of Apps to be installed is large. Since the upper-layer installation process and the lower-layer optimization process of the plurality of Apps are performed sequentially, and the lower-layer optimization process of the Apps occupies a relatively long time, the installation process consumes a large amount of time, and the user experience is reduced.

[0003] Therefore, how to quickly and efficiently install Apps in batches has become a technical problem to be solved. SUMMARY

[0004] The present application provides a method for installing an application and an electronic device, which is beneficial to improve the installation speed of the electronic device for installing a plurality of applications, thereby improving the user experience.

[0005] In a first aspect, a method for installing an application is provided. The method is applied to an electronic device, and includes: detecting that a user triggers an operation of installing a first application program and a second application program; in response to the operation, copying and scanning a first application package, the first application package being an application package corresponding to the first application program; within a first time period after the copying and scanning of the first application package, copying and scanning a second application package, the second application package being an application package corresponding to the second application program; within a second time period after the copying and scanning of the first application package, performing optimization on the first application program; and wherein the first time period and the second time period at least partially overlap.

[0006] Based on the technical solution, when the electronic device installs an application, the upper-layer installation process and the lower-layer optimization process of the application are performed in parallel, which is beneficial to improve the installation speed of the electronic device for installing a plurality of applications, thereby improving the user experience.

[0007] In combination with the first aspect, in some implementations of the first aspect, the method further includes: detecting that a user triggers an operation of installing a third application program and a fourth application program; within a third time period after the copying and scanning of the first application package, copying and scanning a third application package, the third application package being an application package corresponding to the third application program; and wherein when a time length of the second time period is greater than a sum of time lengths of the first time period and the third time period, a starting time of copying and scanning the fourth application package is later than or equal to a starting time of performing optimization on the second application program.

[0008] Based on the technical scheme, when the bottom-layer optimization process of an application takes a long time to execute, the technical scheme is beneficial to avoid too many optimization tasks from being accumulated in the bottom-layer optimization queue.

[0009] With reference to the first aspect, in some implementations of the first aspect, the method further includes: detecting that a user triggers an operation of installing a third application program; detecting a temperature of a central processing unit (CPU) of the electronic device when the copying and scanning of the second application program package are completed; determining that the temperature is greater than or equal to a preset value; pausing for a first preset time period when the optimization of the second application program ends; and copying and scanning a third application program package after the first preset time period, the third application program package being an application program package corresponding to a third application program.

[0090] The SIM card interface 195 is used to connect a SIM card.

[0091] The software system of the electronic device 100 can employ a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. Embodiments of the present application take the Android system with a layered architecture as an example to illustrate the software structure of the electronic device 100.

[0092] Figure 2 is a software structure block diagram of the electronic device 100 of embodiments of the present application. The layered architecture divides the software into several layers, each of which has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer. The application layer can include a series of application packages.

[0093] As shown in Figure 2 , the application packages can include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0094] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications of the application layer. The application framework layer includes some pre-defined functions.

[0095] As shown in Figure 2 , the application framework layer can include a package manager service (PMS), a window manager, a content provider, a view system, a resource manager, a notification manager, etc.

[0096] The PMS is used to manage the installation and uninstallation of various software.

[0097] The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, and take screenshots, etc.

[0098] The content provider is used to store and obtain data, and make the data accessible to the applications. The data can include videos, images, audios, dialed and received calls, browsing history and bookmarks, phone books, etc.

[0099] The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build applications.

[0100] The resource manager provides various resources for the application program, such as localized strings, icons, pictures, layout files, video files, and the like.

[0101] The notification manager enables the application program to display notification information in the status bar, which can be used to convey a notification type of message, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the completion of downloading, message reminders, and the like.

For example, a text information is prompted in the status bar, a prompt sound is emitted, the electronic device is vibrated, an indicator light is blinked, and the like.

[0102] The Android runtime includes a core library and a virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

[0107] For ease of understanding, the following embodiments of the present application will take an electronic device with the structure shown in Figure 1 and Figure 2 as an example, and the method for installing an application provided by the embodiments of the present application will be specifically described in combination with the drawings and application scenarios.

[0108] Before describing the method for installing an application of the embodiments of the present application, first, the terms in the embodiments of the present application are simply introduced.

[0109] 1、Android application package (APK): is a kind of application package file format used by Android operating system, used for distributing and installing mobile applications and middleware. The code of an Android application wants to run on an Android device must be compiled first, and then packaged into a file that can be recognized by the Android system before it can be run, and this file format that can be recognized and run by the Android system is "APK". APK is composed of xml, resource files and dex (binary bytecode) files.

[0110] 2、Blocking call: the current thread is suspended before the call result is returned.

[0111] 3、dexopt thread: used to execute dexopt tasks, dexopt is a process of verifying and optimizing dex files to generate executable odex files. This process can improve application startup and component loading performance.

[0112] 4、dex2oat thread: used to execute dex2oat work tasks, dex2oat is a process of optimizing APK files to generate oat files. oat files are a kind of Android private elf file format, which not only contains native machine instructions translated from dex files, but also contains original dex file contents. For APK, oat files are actually a package of odex files, that is, oat = odex.

[0113] 5、dex2oat work task queue management thread: used to manage the dex2oat work task queue, used to take dex2oat work tasks from the dex2oat work task queue.

[0114] Figure 3 is a schematic diagram of a group of graphical user interfaces (GUIs) provided by an embodiment of the present application. The embodiment of the present application takes the example of a user installing multiple applications on a mobile phone. Among them, (a) to (d) in Figure 3 show the process of the user installing multiple applications at a time.

[0115] Referring to (a) in Figure 3 , the GUI is the desktop 200 of the mobile phone. When the mobile phone detects the user's operation of clicking the icon 210 of the application market on the desktop 200, it can display the GUI as shown in (b) in Figure 3 .

[0116] Referring to (a) in Figure 3(b) in FIG. 1C, which is a GUI of an application market where a user can download various applications, for example, a plurality of applications at a time, and when the phone detects that the user clicks the download controls 220, 230, and 240 in sequence, the phone starts to download the applications, and can display a GUI as shown in Figure 3 (c) in FIG. 1C.

[0117] Referring to Figure 3 (c) in FIG. 1C, the phone can display the progress of the plurality of applications being downloaded on the interface.

[0118] Referring to Figure 3 (d) in FIG. 1C, when the plurality of applications are downloaded and installed, the phone can display icons of the plurality of applications on the desktop 220 of the phone.

[0119] Figure 4 is a flowchart of installing an application provided in an embodiment of the present application. Take an electronic device based on an Android system as an example, the electronic device installs an application through a package installer interface. As shown in Figure 4 , the step includes steps 101 to 107.

[0120] Step 101, an application program layer creates a task.

[0121] In this embodiment, the application installation party creates a task through a package installer session (PIS).

[0122] Step 102, the task is submitted to a PMS in an application framework layer, and the PMS installs the application.

[0123] Step 103, the PMS installs the application.

[0124] In this embodiment, when the PMS installs the application, the PMS copies an APK file of the application from a download directory of the application to a system directory, and scans the APK file, and through the scanning process, the PMS parses the APK file to obtain information such as components and configuration files of the application.

[0125] Step 104, the PMS calls an installd interface of a system layer to perform dexopt to optimize the APK file.

[0126] In this embodiment, the PMS blocks the calling of the installd interface.

[0127] Step 105, the installd calls a dex2oat thread.

[0128] Wherein, installd internally calls the dex2oat thread to perform binary optimization on the APK file during dexopt, so as to improve the application startup speed and component loading performance.

[0129] Step 106, installd sends a message to PMS that the execution of the dex2oat thread is completed.

[0130] Step 107, PMS judges that the dexopt execution is completed, and then sends a message to the application installation party that the App installation is completed.

[0131] In the above application installation process, for a single application installation, the installation process needs to block and wait for the dex2oat optimization process, and the dex2oat optimization process generally takes a long time, for example, the installation time of a typical application WeChat (about 120MB in size) on an electronic device is 14s in total, and the dex2oat optimization process takes about 7s, accounting for about half of the entire application installation time.

[0132] Figure 5 is a time sequence flowchart of PMS internal application installation provided by the embodiment of the present application. As shown in the figure, Figure 5 the flowchart can include steps 201 to 206.

[0133] 201, PMS starts installing App1.

[0134] Wherein, PMS holds the mInstallLock lock when starting to install App1, and the mInstallLock lock is an installation lock protection file, which prevents other application installations when the current application installation is not completed.

[0135] 202, PMS submits the dexopt1 task.

[0136] Wherein, PMS submits the dexopt1 task to the package dex optimizer, and optimizes the APK file of App1.

[0137] 203, the package dex optimizer sends the dexopt1 task to installd.

[0138] Wherein, the process holds the mInstallLock lock again, and the installation lock protection file prevents other dexopt tasks from being performed when the current dexopt task is not completed.

[0139] 204, installd internally calls the dex2oat thread to perform the dex2oat work task to perform binary optimization on the APK file.

[0140] 205, after the dex2oat work task is executed, installd sends a message to PMS that the installation of App1 is completed.

[0141] 206, after receiving the message that the installation of App1 is completed, PMS sends the message to the application installation party.

[0142] 207, PMS starts the installation of App2.

[0143] It should be understood that after the execution of the dex2oat work task is completed, the mInstallLock lock is returned in turn, and during this period, the installation application is blocked and waits, and the installation request of other applications cannot be executed.

[0144] Therefore, during the batch application installation process, due to the existence of the mInstallLock lock, the installation of multiple applications and the dex2oat work task are sequentially and serially performed, resulting in slow multiple application installation process and poor user experience. Therefore, a method for quickly installing applications is needed to improve user experience.

[0145] It should be understood that the process of copying and scanning the APK file by PMS in the embodiments of the present application can be referred to as "upper layer" or "upper layer installation", and the optimization process of dexopt or dex2oat can be referred to as "bottom layer" or "bottom layer optimization".

[0146] As described above, during the batch installation of applications by the electronic device, the upper layer installation process and the bottom layer optimization process of multiple applications are sequentially and serially performed, resulting in slow multiple application installation process and poor user experience.

[0147] The present application provides a method for installing applications, which separates the execution process of the dex2oat work task, i.e., the bottom layer optimization process of the application, from the entire installation process during the batch installation of applications by the electronic device, so as to achieve parallel processing of the upper layer installation of the application and the bottom layer optimization of the application, thereby accelerating the installation speed during the installation of multiple applications and improving user experience.

[0148] Figure 6 is another time sequence flow diagram for installing applications internally provided by the PMS in the embodiments of the present application. As shown in Figure 6 the flow can include steps 201a to 206a.

[0149] 201a, PMS starts to install App1.

[0150] 202a, PMS submits the dex2oat work task of App1 to the optimizer.

[0151] In particular, the PMS submits the dex2oat work task into the dex2oat work task queue, which is managed by a dex2oat work task queue management thread.

[0152] 203a, the PMS sends a message to the application installation party that the installation of App1 is completed.

[0153] It should be understood that the steps 202a and 203a can be performed simultaneously.

[0154] 204a, the PMS starts installing App2.

[0155] 204b, the optimizer calls the installd interface.

[0156] In particular, the dex2oat work task queue management thread is used to take the dex2oat work task out of the queue.

[0157] 205b, after the dex2oat work task corresponding to the App1 is taken out, the installd interface internally calls the dex2oat thread to execute the dex2oat work task.

[0158] It should be understood that the steps 204b and 205b are performed in parallel with the step 204a, and the execution of the steps 204b and 205b does not affect the performance of the step 204a.

[0159] 205a, the PMS submits the dex2oat work task of App2 to the optimizer.

[0160] 206a, the PMS sends a message to the application installation party that the installation of App2 is completed.

[0161] 206b, after the execution of the step 205b is completed, the dex2oat work task management thread takes the dex2oat work task corresponding to App2 out of the queue and calls the installd interface.

[0162] 207b, the installd interface internally calls the dex2oat thread to execute the dex2oat work task corresponding to App2.

[0163] Similarly, the step 207b and the step 208b do not affect the installation of the next application.

[0164] In the embodiments of the present application, the upper-layer installation of the PMS and the lower-layer optimization process of the application are performed in parallel, and compared with the existing serial installation process, the technical solution can improve the installation speed when a batch of applications are installed, and improves the user experience.

[0165] Figure 7is a method flowchart for installing an application provided by an embodiment of the present application. As shown in Figure 7 The method can include steps 301 to 305.

[0166] 301, a user installs an application.

[0167] For example, the user downloads and installs multiple applications in an application market, or restores multiple applications using a clone backup.

[0168] 302, copy the APK file.

[0169] The application installation party copies the APK file to facilitate subsequent installation.

[0170] 303, scan the APK file.

[0171] The PMS scans the APK file to parse the APK file to obtain the components, configuration files, and other information of the application.

[0172] 304, submit a dex2oat work task.

[0173] The PMS calls the installd interface to perform dexopt optimization, and the installd internally calls the dex2oat thread to perform the dex2oat optimization process to optimize the APK file.

[0174] It should be understood that in the process of batch installing applications in the electronic device, each application corresponds to a dex2oat work task. The electronic device can form a queue of dex2oat work tasks corresponding to the applications according to the order of installing the applications. For example, the electronic device installs App1, App2, and App3 in sequence, and their respective dex2oat work tasks are dex2oat1, dex2oat2, and dex2oat3, respectively. The dex2oat work task queue is dex2oat1, dex2oat2, and dex2oat3. During the application installation process, the background dex2oat work task queue management thread takes the dex2oat work tasks from the task queue in sequence, and the installd internally calls the dex2oat thread to perform the dex2oat optimization process, so as not to hinder the execution of the installation process. This process separates the dex2oat work task execution process from the entire application installation process, and performs parallel processing of application installation and dex2oat execution process, so that batch applications can be quickly installed.

[0175] Specifically, this step 304 can include steps 3041 to 3046.

[0176] 3041, start a background dex2oat work task queue management thread.

[0177] The dex2oat work task queue management thread is used to manage the dex2oat work task queue, and the dex2oat work tasks are sequentially taken out from the dex2oat work task queue.

[0178] 3042, waiting for the dex2oat work task queue.

[0179] For example, the electronic device sequentially installs App1, App2, and App3, and the dex2oat work tasks are dex2oat1, dex2oat2, and dex2oat3.

[0180] 3043, if the dex2oat work task idles for a timeout, the dex2oat work task queue management thread is ended.

[0181] The idle timeout can be understood as that the time for which no task in the dex2oat work task queue is executed is greater than a preset value, that is, it can be considered that the dex2oat work tasks in the dex2oat work task queue have all been executed and ended, at which time the system stops the work task queue management thread, which is beneficial to reduce the power consumption of the electronic device.

[0182] 3044, if the dex2oat does not idle, the dex2oat work task is obtained.

[0183] 3045, the dex2oat work task is executed.

[0184] The installd executes the dex2oat work task by calling the dex2oat thread to perform binary optimization on the APK file of the application.

[0185] 3046, the dex2oat work task execution is ended.

[0186] The dex2oat thread compiles the dex file into the oat file format, and the dex2oat work task of the application is ended.

[0187] It should be understood that the above process is the execution process of the dex2oat work task of an application, and after the dex2oat work task of the application is executed, the execution process of the dex2oat work task of the next application is the same as the above steps 3042 to 3046, and will not be repeated.

[0188] It should also be understood that the order of installing the application can be the order in which the electronic device completes downloading the application, or the order according to the preset priority, and the embodiments of the present application do not make specific limitations.

[0189] 305, the installation of the application is completed.

[0190] It should be understood that, in step 305, once the dex2oat work task corresponding to the application is submitted in step 304, it can be considered that the installation of the application is completed, that is, the installation of the next application can be performed, and the dex2oat work task corresponding to the application is transferred to background execution. At this time, the PMS sends a broadcast message to the application installation party that the installation of the application is completed.

[0191] For example, the application currently being installed is App1, and after the dex2oat1 corresponding to App1 is submitted in step 304, it can be considered that the installation of App1 is completed, and the installation of App2 can be performed, and at the same time of installing App2, dex2oat1 is executed in the background.

[0192] Based on the above technical solution, when installing applications in batches on the electronic device, the dex2oat work task corresponding to the application can be separated from the installation process, and the upper-layer application installation and the lower-layer dex2oat optimization process can be processed in parallel, so that the installation speed of the batch application can be accelerated, and the user experience can be improved.

[0193] Figure 8 is a timing diagram for installing an application provided by an embodiment of the present application. As shown in Figure 8 In the prior technical solution, when the electronic device installs applications in batches, the multiple applications are installed in series one by one. For example, before installing App2, the dex2oat work task of App1 must be executed, and similarly, before installing App3, the dex2oat work task of App2 must be executed. Therefore, the batch application installation is slow, which affects the user experience.

[0194] In the embodiment of the present application, as shown in Figure 8 In response to the operation of installing the application program triggered by the user, APK1 corresponding to the first application program (that is, installing App1 in the upper layer) is copied and scanned, APK2 corresponding to the second application program (that is, installing App2 in the upper layer) is copied and scanned within the first time period t1 after copying and scanning APK1 corresponding to the first application program, and the optimization of the first application program is performed within the second time period t2 after copying and scanning APK1 corresponding to the first application program, that is, dex2oat1 is executed within time t2, wherein the first time period t1 and the second time period t2 at least partially overlap.

[0195] As shown in Figure 8 The starting times of the first time period t1 and the second time period t2 are the same, and at this time, dex2oat1 and the upper-layer installation of App2 are performed in parallel, so that the installation speed of the application can be improved, and the user experience can be improved.

[0196] In another example, the start times of t1 and t2 can also be different. For example, the start time of t2 is earlier than the start time of t1, but the time periods of t1 and t2 overlap at least partially. This can also enable the parallel execution of the upper-level installation of App2 and the lower-level optimization of App1, thereby improving the installation speed of multiple applications.

[0197] In one possible implementation, the first optimization task corresponding to App1, namely the dex2oat task, can be added to the first task queue; the first thread can retrieve the first optimization task from the first task queue; and the first interface can be called to start the second thread to execute the first optimization task.

[0198] For example, the first task queue is the dex2oat task queue, the first thread is the dex2oat task queue management thread, the first interface is the installd interface, and the second thread is the dex2oat thread.

[0199] Based on the application installation method provided in this application embodiment, when installing App1 and App2, the time that can be optimized compared to the original application installation method is the sum of the time spent executing dex2oat1 and executing dex2oat2.

[0200] Figure 9 This is a timing diagram illustrating the installation of an application according to an embodiment of this application. In this embodiment, during batch application installation, the following situation may occur: the execution process of dex2oat1 corresponding to App1 takes a long time, such as... Figure 9 As shown in (a), after App1 is installed, App2 begins installation, and the underlying layer begins executing dex2oat1 on App1. After App2 is installed, dex2oat2 is added to the dex2oat task queue. Since dex2oat1 has not yet finished executing, dex2oat2 can only wait in the queue for execution. Then, App3 begins installation. After App3 is installed, dex2oat3 is added to the dex2oat task queue for execution. App4 begins installation. After App4 is installed, dex2oat4 is added to the dex2oat task queue for execution. At this point, dex2oat1 still has not finished executing. Therefore, the result is a backlog of tasks in the dex2oat task queue that are not actually executed. If the electronic device experiences an abnormal situation (e.g., shutdown or restart), some apps may not have executed their corresponding dex2oat tasks. In this case, when the user activates the application, it will start in normal mode.

[0201] It should be understood that dex2oat optimization of the App can improve the startup speed and component loading performance of the App, and the normal mode is not optimized for the App, and the App may be slow to start.

[0202] To address the above-mentioned situations, the embodiments of the present application provide a method that can control the number of backlog tasks in the dex2oat work task queue. As shown in (b) in FIG. 1, Figure 9 The method can include the following steps:

[0203] (1) The upper layer installation of App1 is completed, App2 is installed in the upper layer within a first time period t1 after the upper layer installation of App1 is completed, and optimization of App1 is performed within a second time period t2 after the upper layer installation of App1 is completed.

[0204] For example, the starting times of the first time period t1 and the second time period t2 are the same, that is, the lower layer starts to perform dex2oat1 on App1 at the same time as the upper layer installation of App2.

[0205] (2) App3 is installed in the upper layer within a third time period t3 after the upper layer installation of App1 is completed.

[0206] For example, the upper layer installation of App2 is completed, and dex2oat1 has not been completed, at which time, dex2oat2 corresponding to App2 is added to the waiting queue, and the upper layer starts to install App3.

[0207] (3) Optimization of App2 is performed within a fourth time period t4 after the upper layer installation of App1 is completed.

[0208] For example, dex2oat2 corresponding to App2 is added to the waiting queue and is executed within the fourth time period t4.

[0209] Specifically, the dex2oat work task queue management thread (i.e., the first thread) takes the dex2oat2 out of the queue, the PMS calls the installd interface for execution, and the installd internally starts the dex2oat thread (i.e., the third thread) to execute the dex2oat2.

[0210] (4) App4 is installed in the upper layer within a fifth time period t5 after the upper layer installation of App1 is completed, and when the length of the second time period t2 is greater than the sum of the lengths of the first time period t1 and the third time period t3, the starting time of copying and scanning the fourth application package (i.e., the starting time of t5) is later than or equal to the starting time of performing optimization on the second application (i.e., the time of t4).

[0211] When the length of the second time period t2 is greater than the sum of the lengths of the first time period t1 and the third time period t3, it means that the underlying optimization task of App1 takes a long time, and if not controlled, multiple dex2oat work tasks may be accumulated in the underlying dex2oat work task queue. At this time, the PMS does not send the App3 installation completion broadcast to the application installation party, but waits for the underlying dex2oat1 to execute. At the same time when the underlying dex2oat1 executes, the dex2oat2 starts to execute, and at this time, the dex2oat3 corresponding to App3 is added to the dex2oat waiting queue, so that the dex2oat work task queue waits to execute is dex2oat3. At this time, the PMS sends the App3 installation completion message to the application installation party, and the upper layer starts to continue to install App4. At this time, the starting time of the optimization of App2 is equal to the starting time of the copying and scanning of App4, that is, the upper layer installs App4 and the underlying executes dex2oat2 at the same time.

[0212] It should be understood that the installation of subsequent more applications can refer to the above installation process, which will not be described in detail.

[0213] It should be understood that the above process is described by taking one dex2oat work task accumulated in the dex2oat work task queue as an example, but the embodiments of the present application are not limited thereto. The number of dex2oat work tasks accumulated in the dex2oat work task queue in the embodiments of the present application can also be two, three or more.

[0214] Based on the above technical solution, when installing a batch of applications, when the dex2oat execution process of a certain application takes a long time, the scheme can avoid too many dex2oat work tasks accumulated in the dex2oat work task queue.

[0215] Figure 10 is a method flow diagram provided by an embodiment of the present application for installing an application. The method can include steps 401 to 408.

[0216] 401, the user installs an application.

[0217] 402, copy the APK file.

[0218] 403, scan the APK file.

[0219] It should be understood that the above steps 401 to 403 can refer to the foregoing description, and will not be described in detail for brevity.

[0220] 404, submit a dex2oat work task.

[0221] PMS calls the installd interface to perform dexopt optimization, while installd internally calls the dex2oat thread to perform the dex2oat optimization process.

[0222] 405, Parallelize dex2oat worker tasks.

[0223] As mentioned above, the application installation method in this application embodiment allows for parallel processing of the upper-layer App installation and the lower-layer dex2oat task execution, thereby accelerating the application installation speed.

[0224] 406. If the dex2oat worker task waiting queue is not empty, then the blocking waiting queue will be cleared.

[0225] It should be understood that the dex2oat job waiting queue represents a queue of dex2oat jobs waiting to be executed, in addition to the currently executing dex2oat job.

[0226] During the application installation process, when the upper-layer app installation and the lower-layer dex2oat job tasks are processed in parallel, if the current dex2oat job task waiting queue is not empty, it means that the current dex2oat job task has not yet been completed. At this time, PMS will block and wait for the dex2oat job task to be completed before notifying the application installer that the application installation is complete.

[0227] For example, refer to Figure 9 In scenario (b), when the upper layer installs App3, and PMS submits dex2oat3, dex2oat1 has not yet finished executing. At this time, dex2oat2 is still waiting to be executed in the dex2oat task queue. Therefore, PMS does not send a message indicating that App3 has been installed to the application installer, but instead blocks and waits for dex2oat1 to finish executing. After dex2oat1 finishes executing, dex2oat2 begins execution, and the waiting queue is empty at this point.

[0228] 407. If the dex2oat job waiting queue is empty, submit the dex2oat job.

[0229] If the dex2oat job queue is empty, it means that there are no dex2oat jobs waiting to be executed in the dex2oat job queue. At this time, you can submit the dex2oat job for the application to the dex2oat job queue, that is, add the dex2oat job corresponding to the application to the dex2oat job waiting queue.

[0230] In one example, the dex2oat work task queue is not empty in step 406, and the PMS blocks and waits for the queue to be emptied. After the queue is emptied, the PMS submits the dex2oat work task of the application to the task queue. For example, referring to FIG. 6, after the dex2oat1 execution is completed, the dex2oat2 execution is started. At this time, the dex2oat waiting queue is empty, the PMS sends the App3 installation completion broadcast to the application installer, and the dex2oat3 corresponding to the App3 is added to the dex2oat waiting queue to wait for execution. Figure 9

[0231] In another example, the upper layer installs the App3, and the lower layer is executing the dex2oat2. At this time, there is no dex2oat work task waiting for execution in the dex2oat work queue, and the dex2oat3 is added to the dex2oat work task queue to wait for execution.

[0232] 408, the application installation is completed.

[0233] After the dex2oat work task of the current installation App is submitted to the dex2oat work task queue, the PMS sends the App installation completion broadcast to the application installer.

[0234] It should be understood that at this time, although the PMS sends the App installation completion broadcast to the application installer, the dex2oat work task corresponding to the App is still executed in the background or waits for execution.

[0235] Based on the above technical solutions, when a plurality of applications are installed, the scheme can avoid too many dex2oat work tasks in the dex2oat work task queue.

[0236] During the batch application installation process, the dex2oat work task of the application is executed in the local system of the electronic device. Since the dex2oat execution process is a high-computing process, there is relatively high power consumption, which causes the temperature of the electronic device to rise in a short time, thereby possibly affecting the stability of the electronic device. Therefore, the present application embodiment provides a temperature control strategy method to improve the above problems.

[0237] Figure 11 is a timing flow diagram of a method of an installation application temperature control strategy provided by the present application embodiment. As shown in FIG. 7, the method includes the following steps. Figure 11 ​As shown, the upper layer of the electronic device installs App1, the lower layer starts to execute dex2oat1, and the upper layer starts to install App2. When preparing to submit dex2oat2, that is, at T1, the temperature of the electronic device is monitored. The temperature can be the temperature of the entire electronic device or the temperature of the central processing unit (CPU) of the electronic device.

[0238] For example, a threshold range of the temperature can be set in advance. When the temperature is greater than a first threshold, it is considered that the temperature of the electronic device is abnormal, and when the temperature is less than or equal to the first threshold, it is considered that the temperature of the electronic device is normal. For example, the first threshold can be any value between 35 degrees and 40 degrees.

[0239] If the temperature of the electronic device is detected to be abnormal at T1, a first execution duration (that is, a fourth time period) is determined. The first execution duration is used to represent the duration for which the electronic device continuously executes the dex2oat work task. The first execution duration can be used to determine whether the dex2oat work task has been executed for a long time. If the dex2oat work task has been executed for a long time, the PMS does not send the App2 installation completion broadcast to the application installation party, and triggers to stop the dex2oat work task, that is, suspends the dex2oat work task queue management thread for a first preset duration, that is, suspends the scheduling of the dex2oat work task for the first preset duration. In other words, App3 is copied and scanned after the first preset duration. It should be noted that the execution process of the current dex2oat work task is not stopped immediately, but the dex2oat2 execution of App2 is completed before the dex2oat work task is stopped, as shown in T2 in FIG. 7. Figure 11 Because the scanning and dex2oat optimization process of the App is an installation process, it is tried to avoid separation and to avoid the problem of insufficient stability.

[0240] Alternatively, when the temperature of the electronic device is detected to be abnormal at T1, the dex2oat work task can be triggered to be stopped, that is, the dex2oat work task queue management thread is suspended for a first preset duration. Similarly, the dex2oat work task is stopped after the dex2oat2 execution of App2 is completed.

[0241] It should be understood that the temperature monitoring in the embodiments of the present application can be realized by a temperature sensor or other sensors with temperature monitoring function, and the embodiments of the present application do not make specific limitation thereto.

[0242] It should be understood that in the embodiments of the present application, whether the current dex2oat optimization process has been executed for a long time can be determined by counting the execution time of the current dex2oat optimization process. For example, if the execution time of the current dex2oat optimization process is greater than a preset value, it can be considered that the current dex2oat optimization process has been executed for a long time. The process of determining whether the current dex2oat optimization process has been executed for a long time will be described in detail below in conjunction with specific embodiments, which will not be described here in detail.

[0243] At time T2, the dex2oat work task queue management thread is triggered to stop and rest for a period of time until time T3. The rest time interval can be a preset time length, for example, 5s or 10s or other values.

[0244] At time T3, the dex2oat work task has been suspended for a period of time t, the PMS sends an App2 installation end broadcast to the application installation party, and starts to install App3.

[0245] At time T4, the upper-layer installation of App3 is completed, and the lower-layer starts to execute dex2oat3.

[0246] It can be seen that from the time T2 when the dex2oat work task is triggered to stop to the time T4 when the dex2oat3 is started to execute, the rest time of the dex2oat work task is actually from T2 to T4, thereby effectively reducing the heating problem of the electronic device in the batch installation of applications in a short period of time.

[0247] It should be understood that the installation of more subsequent applications can refer to the above-mentioned times T1 to T4, and for the sake of brevity, will not be described here.

[0248] The following will be described in conjunction with Figure 12 The method for counting the execution time of the dex2oat work task in the embodiments of the present application.

[0249] Figure 12 is a flowchart of a process for counting the working time of the dex2oat work task provided by the embodiments of the present application. As Figure 12 shown, the method can include steps 501 to 509.

[0250] Step 501, a user installs an application.

[0251] Step 502, a dex2oat work task is submitted.

[0252] Step 503, the dex2oat work task starts to execute, and the time T1 is recorded.

[0253] Step 504, the dex2oat work task is executed, and the time T2 is recorded.

[0254] Step 505, record the dex2oat execution time of this time: dT = T2 - T1.

[0255] Step 506, calculate the time interval between the dex2oat task of this time and the dex2oat task of last time: AT = T1 - LT2.

[0256] Wherein, AT represents the time interval between the dex2oat task of this time and the dex2oat task of last time, and LT2 represents the time when the dex2oat task of last time is executed and completed.

[0257] Step 507, if AT ≤ MIN_INTER, the working time WT of dex2oat is the sum of the working time of this dex2oat and the working time of last dex2oat.

[0258] Wherein, WT represents the working time of dex2oat, and MIN_INTER represents the minimum time interval. It should be understood that the minimum time interval can be a pre-set value, for example, the minimum time interval can be 20s or 30s or other values.

[0259] If the time interval AT between the dex2oat task of this time and the dex2oat task of last time is less than or equal to the minimum time interval MIN_INTER of dex2oat, the dex2oat working time is accumulated.

[0260] Exemplarily, as shown in the figure, Figure 11 In the fifth time period t5 before copying and scanning the first application App1, the underlying optimization dex2oat0 of the fourth application App0 is executed, if at T1, the interval between the fifth time period t5 of executing dex2oat0 and the second time period of executing dex2oat1 is less than or equal to the minimum time interval (i.e. the third preset time length), then the working time WT of dex2oat (i.e. the fourth time period) is the sum of the time length of the fifth time period t5 and the second time period t2.

[0261] Step 508, if AT > MIN_INTER, the working time of dex2oat: WT = dT.

[0262] If the time interval AT between the dex2oat task of this time and the dex2oat task of last time is greater than the minimum time interval MIN_INTER of dex2oat, the execution time dT of this dex2oat is taken as the working time of dex2oat.

[0263] Exemplarily, as shown in the figure, Figure 11At the T1 moment shown, if the interval between the fifth time period t5 and the second time period t2 is greater than the third preset time length, the working time WT (the fourth time period) of dex2oat is the execution time of dex2oat1, that is, the first time period t1.

[0264] Step 509, LT2 = T2.

[0265] At the start of the next dex2oat working task, the time at which the current dex2oat working task is executed is taken as LT2.

[0266] It should be understood that the statistics of the working time of the next dex2oat working task or multiple dex2oat working tasks can refer to the above steps, and for the sake of brevity, will not be repeated.

[0267] The following will be described in combination with Figure 13 The method for optimizing the temperature control strategy of the embodiment of the present application.

[0268] Figure 13 is a temperature control strategy optimization process schematic diagram provided by the embodiment of the present application. As Figure 13 shown, the method can include steps 601 to 606.

[0269] Step 601, install App2.

[0270] It should be understood that before this step 601, the upper layer has installed App1, and the installation of App2 by the upper layer and the execution of the dex2oat working task by the bottom layer in this step are performed in parallel.

[0271] Step 602, submit a dex2oat working task.

[0272] Step 603, the system reads temperature information Temp according to the temperature monitoring result.

[0273] Among them, the system can monitor the temperature of the electronic device according to the temperature sensor, and the temperature can be the whole machine temperature of the electronic device or the temperature of the CPU.

[0274] Step 604, according to the temperature monitoring result in step 603, if the temperature Temp of the electronic device at this time is greater than MIN_TEMP, and the dex2oat working time WT is greater than MAX_WT, trigger the dex2oat working task to be suspended.

[0275] Wherein, MIN TEMP represents a threshold temperature, which is a critical temperature for determining whether the temperature of the electronic device is abnormal when installing an application, and MAX WT represents the longest working time. The value of MIN TEMP and the value of MAX WT can be achieved by system preset. As described above, the MIN TEMP can be any value between 35 degrees and 40 degrees, and the MAX WT can be any value between 20s and 30s.

[0276] It should be understood that the WT in the embodiments of the present application can obtain the working time of the dex2oat work task by the method of Figure 10

[0277] In step 604, although the dex2oat work task is triggered to stop, in order to avoid the stability problem in the application installation process, the dex2oat work task currently being executed is not stopped immediately, but the dex2oat2 of App2 is executed to completion before the dex2oat work task is stopped, as described above.

[0278] Step 605, dex2oat2 execution is completed.

[0279] After the dex2oat2 execution is completed, the dex2oat work task will stop for a period of time to avoid the problem of insufficient stability of the electronic device due to excessive temperature.

[0280] Step 606, WT zero processing.

[0281] When the dex2oat work task is triggered to stop, the working time WT of dex2oat is set to zero to facilitate the statistics of the working time of dex2oat in the next cycle.

[0282] Based on the above technical method, when installing a batch of applications, since there is more power consumption in the execution process of the dex2oat work task, the temperature control strategy optimization method in the embodiments of the present application can avoid the problem of insufficient stability of the electronic device due to excessive temperature.

[0283] Figure 14 is an exemplary flowchart of a method for installing an application provided by the embodiments of the present application. As Figure 14 shown, the method can include steps 710 to 740.

[0284] 710, the electronic device detects that the user triggers the operation of installing an application program.

[0285] For example, the user downloads and installs multiple applications at a time in the application market, or the user uses the electronic device to clone and restore multiple applications, clones multiple applications from one device to another device, etc.​

[0286] 720, in response to the operation, copying and scanning the first application package, the first application package being the application package corresponding to the first application.

[0287] The electronic device copies and scans the first application package in response to the operation of the user, that is, the electronic device installs the first application at the upper layer.

[0288] 730, within a first time period after copying and scanning the first application package, copying and scanning a second application package, the second application package being the application package corresponding to the second application;

[0289] The first time period can start immediately after the electronic device scans and copies the first application package, or can start after a period of time after the electronic device scans and copies the first application package.

[0290] 740, within a second time period after copying and scanning the first application package, performing optimization on the first application; wherein the first time period and the second time period at least partially overlap.
