[0002] The Android system can record frequently used codes during the execution of an application, namely hotspot codes, and compile the hotspot codes to generate native codes when the terminal is in charging and idle state, which will improve the performance of the application in the next use.

[0003] However, on the one hand, when the mobile phone updates the system version by downloading the update package from the remote server through Over-the-Air (OTA) technology, the file recording the hotspot code and the native code generated based on the hotspot code will be deleted, and the hotspot code can only be recompiled when the updated mobile phone is in charging and idle state again; on the other hand, with the development of battery technology, battery capacity is getting larger and charging speed is getting faster, and fewer and fewer users charge their mobile phones all night, resulting in a decrease in the situation where the mobile phone enters the charging and idle state, which makes it easy for the hotspot code to not be compiled in time, thereby affecting the performance of the application.

[0025] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0026] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0027] Below, several technical terms involved in the present disclosure are first explained.

[0028] 1. Hot Spot Code

[0029] Hot code may refer to code that is executed more than a preset threshold number of times during the startup or use of an application, including but not limited to functions, methods, code blocks, classes, etc. For example, in client mode, the Android system regards code that is executed more than 1,500 times as hot code; in server mode, the Android system regards code that is executed more than 10,000 times as hot code.

[0030] 2. Native Code

[0031] Native code is computer programming code that is compiled to run on a specific processor (such as an Intel x86-class processor) and its specific instruction set. Native code is code that has been compiled into processor-specific machine code and can be executed directly by a virtual machine.

[0032] 3. Ahead-of-time compilation

[0033] Ahead of time compilation refers to the act of converting a higher-level programming language (such as C or C++) or intermediate code (such as Java bytecode or .NET Framework Common Intermediate Language (CIL) code) into native code to generate a binary file that can be executed natively. Compiling intermediate code during program execution (such as Just-in-time compilation) may reduce the performance of the application, and ahead of time compilation eliminates the need for this step by occurring before execution rather than during execution.

[0034] Figure 1 A compilation method 100 provided based on one or more embodiments of the present disclosure is shown. The compilation method 100 includes steps S101 to S102:

[0035] Step S101: before the terminal system is updated, a backup file of the hotspot description file of the application is created, wherein the hotspot description file is used to record the hotspot code of the application.

[0036] Exemplarily, the hotspot description file is a profile file, which is used to record the hotspot code of a certain application and can be used for profile-guide compilation.

[0037] In some implementations, the created backup file can be stored in a local designated folder according to a preset storage path, or stored in a cloud server, so that the backup file is not deleted during the system update process.

[0038] It should be noted that, in this embodiment, the hotspot description files of all applications installed in the terminal may be backed up, or one or more specified application hotspot description files may be backed up, and the present disclosure does not impose any limitation thereto.

[0039] Step S102: After the system is updated, when the terminal is in the target running state, the hotspot code of the target application is compiled based on the backup file to generate native code.

[0040] Exemplarily, AOT compilation may be used to compile the dalvik bytecode (dalvikbytecode) as the hot code in the dex file into assembly instructions that can be recognized and executed by the processor, that is, native code (Native Code).

[0041] In some embodiments, the target operating state may be an operating state pre-specified before the terminal leaves the factory, and may be updated or modified in real time according to instructions from the user or an instruction from a remote server.

[0042] In some embodiments, the backup file can be obtained locally based on a preset storage path or downloaded from a cloud server to the local computer.

[0043] In some embodiments, the target operating state is that the screen of the terminal is in an off state, the battery level of the terminal is not less than a preset battery threshold, and the CPU occupancy rate of the terminal is not greater than a preset occupancy threshold. In this embodiment, the compilation of the hotspot code is triggered when the terminal meets the following three conditions at the same time: the screen of the terminal is in an off state, the battery level is not less than a preset battery threshold, and the CPU occupancy rate is not greater than a preset occupancy rate. On the one hand, compiling the hotspot code when the terminal is in the above-mentioned target operating state will not affect the terminal's performance, and the compilation process is imperceptible to the user; on the other hand, the probability of the terminal entering the above-mentioned target operating state is higher than the probability that the terminal is in a charging and idle state, so that the hotspot code of the target application can be compiled into native code in a timely manner.

[0044] In this way, according to the compilation method provided by one or more embodiments of the present disclosure, a backup file is created for the hotspot description file of the application before the system is updated, and after the system is updated, when the terminal is in the target running state, the hotspot code of the target application is compiled based on the backup file to generate native code, thereby avoiding the hotspot description file being deleted due to the system update and resulting in failure to compile in time, and there is no need to wait until the terminal is in a charging and idle state to compile the hotspot code, thereby timely improving the running performance of the application after the system is updated.

[0045] In some embodiments, the target application is determined based on at least one of the following: the number of times the application is used, the duration of use of the application, the installation time of the application, and whether the application has been launched.

[0046] In some embodiments, the target application may be determined by:

[0047] Step A1: determining a first application set based on the number of times the application is used and / or the duration of use;

[0048] Step A2: determining a second application set based on application programs whose installation time is not greater than a preset time threshold;

[0049] Step A3: Determine the target application based on the union of the first application set and the second application set.

[0050] Exemplarily, the applications in the terminal can be sorted based on the number of times the applications are used and / or the duration of use, and the N applications most frequently used by users can be determined; the applications can be sorted based on the installation time of the applications, and the M applications most recently installed can be determined; and duplicate applications can be eliminated to obtain no more than (N+M) target applications.

[0051] According to the compilation method provided by one or more embodiments of the present disclosure, when the terminal is in the target running state, only the hotspot codes of the applications frequently used and recently installed by the user are compiled. On the one hand, it can prevent too many compiled applications from causing excessive power consumption of the terminal and high CPU load; on the other hand, it can enable the application that the user may use next to be compiled in time.

[0052] In some embodiments, the method further includes: after the system is updated, saving the backup file to a directory of the corresponding application for use in compiling the hotspot code of the corresponding application. By saving the backup file to a directory of the corresponding application after the system is updated, it is convenient for the terminal to edit the hotspot code of the corresponding application based on the backup file.

[0053] refer to Figure 2 , Figure 2 A compilation method 200 provided according to another embodiment of the present disclosure is shown. The compilation method 200 includes steps S201 to S206:

[0054] Step S201: before the terminal system is updated, a backup file of the hotspot description file of the application is created, wherein the hotspot description file is used to record the hotspot code of the application;

[0055] Step S202: after the system is updated, the backup file is saved in a directory of a corresponding application, and a third application set is determined based on the application with the hotspot description file;

[0056] Step S203: determining a first application set based on the number of times the application is used and / or the duration of use;

[0057] Step S204: determining a second application set based on application programs whose installation time is not greater than a preset time threshold;

[0058] Step S205: Taking the intersection of the union of the first application set and the second application set and the third application set to obtain a target application set; wherein the target application set may include one or more target application programs to be compiled.

[0059] Step S206: When the screen of the terminal is in an off state, the power of the terminal is not less than a preset power threshold, and the CPU occupancy of the terminal is not greater than a preset occupancy threshold, the hotspot codes of the target application programs in the target application set are compiled one by one based on the backup file to generate native code.

[0060] In this way, according to the compilation method provided by one or more embodiments of the present disclosure, a backup file is created for the hotspot description file of the application before the system is updated, and the target application set is determined based on the number of times the application is used and / or the length of time it is used, the installation time, and whether there is a hotspot description file. After the system is updated, when the screen of the terminal is in an off state, the power level is not less than a preset power threshold, and the CPU occupancy rate is not greater than a preset occupancy rate threshold, the hotspot codes of the target applications in the target application set are compiled one by one based on the backup hotspot description file to generate native code. This can avoid the hotspot description file being deleted due to the system update and resulting in the inability to compile in a timely manner, and there is no need to wait until the terminal is in a charging and idle state to compile the hotspot code, thereby timely improving the running performance of the application after the system is updated.

[0061] Correspondingly, Figure 3 A compiling device 300 provided based on one or more embodiments of the present disclosure is shown, comprising:

[0062] A backup unit 301 is used to create a backup file of a hotspot description file of an application before the terminal system is updated, wherein the hotspot description file is used to record the hotspot code of the application;

[0063] The compiling unit 302 is used to compile the hotspot code of the target application based on the backup file to generate native code when the terminal is in the target running state after the system is updated.

[0064] According to the compilation device provided by one or more embodiments of the present disclosure, by creating a backup file for the hotspot description file of the application before the system is updated, and after the system is updated, when the terminal is in the target running state, the hotspot code of the target application is compiled based on the backup file to generate native code, so that the hotspot description file can be prevented from being deleted by the system update and cannot be compiled in time, and there is no need to wait until the terminal is in a charging and idle state to compile the hotspot code, so that the running performance of the application can be improved in time after the system is updated. In some embodiments, the target running state is that the screen of the terminal is in a screen-off state, the power of the terminal is not less than a preset power threshold, and the CPU occupancy rate of the terminal is not greater than a preset occupancy threshold. In this embodiment, the compilation of the hotspot code is triggered when the terminal meets the following three conditions at the same time: the screen of the terminal is in a screen-off state, the power is not less than a preset power threshold, and the CPU occupancy rate is not greater than a preset occupancy rate. On the one hand, when the terminal is in the above-mentioned target running state, compiling the hotspot code will not affect the terminal's performance, and the compilation process is imperceptible to the user; on the other hand, the probability of the terminal entering the above-mentioned target running state is higher than the probability of the terminal being in a charging and idle state, so that the hotspot code of the target application can be compiled into native code in time.

[0065] In some embodiments, the target application is determined based on at least one of the following: the number of times the application is used, the duration of use of the application, the installation time of the application, and whether the application has been launched.

[0066] In some embodiments, the apparatus 300 further comprises:

[0067] A first application determination unit, configured to determine a first application set based on the number of times the application program is used and / or the duration of use;

[0068] A second application determination unit, configured to determine a second application set based on application programs whose installation time is not greater than a preset time threshold;

[0069] A target application determining unit is configured to determine the target application based on a union of the first application set and the second application set.

[0070] Exemplarily, the first application determination unit may sort the applications in the terminal based on the number of times the applications are used and / or the duration of use, and determine the N applications most frequently used by users; the second application determination unit may sort the applications based on the installation time of the applications, and determine the M most recently installed applications; the target application determination unit may exclude duplicate applications to obtain no more than (N+M) target applications.

[0071] In this way, according to the compilation device provided by one or more embodiments of the present disclosure, when the terminal is in the target running state, only the hotspot codes of the applications frequently used and recently installed by the user are compiled. On the one hand, it can prevent too many compiled applications from causing excessive terminal power consumption and high CPU load; on the other hand, it can enable the application that the user may use next to be compiled in time.

[0072] In some embodiments, the apparatus 300 further comprises:

[0073] A saving unit is used to save the backup file to the directory of the corresponding application after the system is updated, so as to be used for compiling the hotspot code of the corresponding application. By saving the backup file to the directory of the corresponding application after the system is updated, it is convenient for the terminal to edit the hotspot code of the corresponding application based on the backup file.
