detailed description

The technical solutions in this application will be described below with reference to the drawings.

FIG. 1 is a schematic flowchart of Android application from development to operation. As shown in FIG. 1, after the developer develops the APK of the Android application, the APK can be published to the application market. The terminal device can download the APK of the Android application from the application market, and install the Android application and run the Android application according to the APK.

Android applications can also be referred to simply as Android applications. After the developer writes the Android application, the Android software development kit (SDK) tool is required to compile the Android application code together with any data and resource files into a file that can be recognized by the Android operating system. The file format that can be recognized and run by the Android operating system is the APK.

The application market in the embodiments of the present application is also called an application store (APP STORE), which is an electronic application store that provides paid (or free) games or application download services for mobile devices, phones, and tablets. After the developer of the Android application releases the APK of the Android application to the application market, the application market can perform operations such as storage, management, and detection of the APK, thereby providing an application developer or application development company with a way to publish the Android application channel. The application market can be deployed on the server. An example of a server is a computer. The server may be a cloud server. The cloud server can also be called the cloud, and the terminal device can be called the end.

The terminal devices in the embodiments of the present application may refer to user equipment, mobile devices, user terminals, terminals, wireless communication devices, handheld devices with communication functions, computing devices or vehicle-mounted devices, wearable devices, and routing devices.

For example, the terminal device in the embodiment of the present application may be a smartphone, a netbook, a tablet computer, a personal computer, a notebook computer, a TV, a digital video conversion box (also called a set-top box), an e-book, an MP3 player, an MP4 player, a palm Game consoles, home game consoles, electronic watches, electronic radios, headphones, car equipment, navigators, DVD players, smart speakers, smart home equipment, and other devices. The embodiment of the present application does not limit the specific form of the terminal device, as long as the device can run the Android application program, all fall within the scope of the terminal device of the embodiment of the present application.

The terminal device and the server (that is, the application market) can communicate in a wireless or wired manner.

The terminal device can optimize the Android application when installing the Android application or running the Android application.

For example, if an Android virtual machine (Dalvik or ART) is installed on the terminal device, when the Android virtual machine starts running or installs an Android application, it will use the technology such as JIT or AOT in the APK of the Android application * The bytecode in the .dex file is compiled and converted into machine code that can be executed quickly on the CPU of the terminal device.

The optimization of the Android application by the terminal device will increase the operating burden of the terminal device. In response to this problem, this application proposes a method for optimizing an Android application and a method for running an Android application, so as to reduce the operating burden of the terminal device, thereby improving the user experience.

In the method for optimizing Android applications proposed in this application, a set of APK optimization frameworks deployed in the application market (server) can be constructed. A variety of APK optimization tools or optimization tool chains can be inserted in the framework. Or it can be said that the method proposed in this application can optimize the Android application on the server side.

In the embodiment of the present application, the optimization of the Android application may refer to the adjustment and improvement of the Android application (for example, the APK of the Android application) by using software tools. According to the focus of optimization, the optimization of Android applications can be divided into optimization of running speed and efficiency and optimization of code size.

Optimization of running speed and efficiency refers to the use of compiler front-end and back-end compilation optimization to reduce the number of codes or instructions required to complete specified tasks and improve the execution of specified tasks based on fully grasping the characteristics of software and hardware. Efficiency, or reduce the program running memory, or both. On the same processor, applications that have been optimized for running speed take less time to complete specified tasks than applications that have not been optimized, that is, the former has higher operating efficiency than the latter.

Code size optimization means that the application program compiles and optimizes through the compiler to reduce the code amount of the application program or the number of redundant instructions as much as possible under the premise that the required functions can be completed correctly, and reduces the final code volume occupation.

That is, the optimized Android application has less code than the optimized Android application, and / or the optimized Android application has fewer instructions than the optimized instruction, and / Or, the optimized Android application consumes less memory when running.

For example, the Maple tool chain optimized for the dex file in the APK can be inserted into the APK optimization framework on the server. The Maple toolchain can directly compile and convert the dex bytecode in the APK into binary machine code executable by the target machine, and package it as a static SO file. And the Maple tool chain will reduce the number of instructions through a specific algorithm during compilation and conversion to improve the efficiency of the program.

For another example, the LLVM compiler tool chain (low level virtual machine, LLVM) can be deployed in the APK optimization framework on the server. LLVM can optimize the SO library files in the APK, or, in conjunction with the Maple tool chain, optimize the intermediate representation (IR) for the dex files to reduce the number of instructions and improve the efficiency of the program.

LLVM is a framework system that constructs a compiler, written in C ++, and is used to optimize the compile-time, link-time, and run-time of programs written in any programming language. time) and idle-time.

For another example, various types of AOT (Ahead-of-time) compilation optimization tools can be deployed in the APK optimization framework in the server, such as: OpenJDK AOT, Angular AOT compiler, or Android ART. The AOT compilation and optimization tool can perform AOT compilation and optimization on the programs or bytecodes in the APK to reduce the number of instructions, thereby improving the efficiency of the program.

The above-mentioned various tools or tool chains for optimizing application programs are just examples, and other optimization tools or tool chains can be deployed in the APK optimization framework on the server according to the development needs of the APK.

In the method for running an Android application proposed in this application, the end-side can download the optimized Android application from the application market, and install the optimized Android application to the end-side device.

For example, the end-side can download the optimized APK from the application market and install the optimized APK into the end-side device.

In the method for running an Android application proposed in this application, a runtime environment capable of executing the server-optimized Android application can be constructed on the end side. For example, the process of directly executing the optimized file in the APK can be added to the running process of the Android application on the side. In this way, when the application is started on the side, the optimized file can be loaded to run the optimized Android application.

Optionally, a switch that switches the terminal device to execute the Android application before being optimized by the application market and the Android application after being optimized by the application market may also be built on the end side. In this way, the end side can choose to execute the APK before optimization or the APK after optimization.

When the end-side chooses to execute the APK before optimization, the APK can be optimized on the end-side, and the files optimized on the end-side can be executed, so as to achieve the purpose of improving operation efficiency. In other words, the end can also be compatible with the original optimization mode.

FIG. 2 is a schematic flowchart of a method for optimizing an Android application program according to an embodiment of the present application. It should be understood that FIG. 2 shows steps or operations of the method, but these steps or operations are merely examples, and other operations or variations of the operations in FIG. 2 may be performed in the embodiments of the present application.

S202. The server optimizes the file to be optimized in the source APK of the Android application to obtain the target optimized file corresponding to the file to be optimized.

The server can be understood as the application market, and the source APK of the Android application can refer to the APK released or uploaded by the developer to the server.

The source APK includes files to be optimized. The file to be optimized may be understood as a file that needs to be optimized, such as a dex file and / or a library file.

The code size of the target optimization file is less than the code size of the file to be optimized, and / or the number of instructions corresponding to the target optimization file is less than the number of instructions corresponding to the file to be optimized.

The file to be optimized and the target optimized file may have a one-to-one correspondence.

S204, the server sends the target APK of the Android application to the terminal device, and the target APK includes the target optimization file obtained by the server optimization.

The target APK of the Android application refers to an APK obtained by optimizing the source APK by the server. The target APK includes the target optimization file obtained after the file to be optimized is optimized. For example, the target APK includes a target optimized file obtained by optimizing the dex file, and / or a target optimized file obtained after the library file is optimized.

The optimized Android application can consume less memory resources when running.

In the embodiment of the present application, the server optimizes the source APK of the Android application and sends the optimized target APK to the terminal device, so that the terminal device does not need to optimize the Android application by itself, thereby reducing the operation of the terminal device The burden can ultimately improve the user experience.

Before performing the method shown in FIG. 2, the source APK of the Android application has been published or uploaded to the server (or application market).

Before executing the method shown in FIG. 2, a software tool for optimizing the APK of the Android application should be deployed or installed on the server (or application market). A series of software tools or software modules that optimize the APK of the Android application can be called an optimization tool chain.

That is to say, in S202, the server optimizes the source APK of the Android application through the optimization tool chain, thereby obtaining the target APK of the Android application. Specifically, the server optimizes the file to be optimized in the source APK through the optimization tool chain, thereby obtaining the target optimized file in the target APK.

One or more optimization tool chains can be deployed in the server. For example, at least one optimization tool chain among the maple tool chain, the AOT compilation optimization tool chain, and the LLVM tool chain may be deployed on the server. At least one type described herein may be understood as one or more types. In this case, the server optimizing the source APK of the Android application may include: the server uses the optimization tool chain in the at least one optimization tool chain to optimize the file to be optimized in the source APK.

In the optimization method of the embodiment of the present application, when the server optimizes the APK of the Android application, in some possible implementation manners, the server may use multiple optimization tool chains deployed on the server to optimize the APK of the Android application, Multiple target APKs are obtained, and the multiple optimization tool chains correspond to the multiple target APKs. Each target APK is obtained by optimizing the source APK with its corresponding optimization tool chain.

For example, if four optimization toolchains, maple toolchain, Java toolchain, AOT toolchain, and LLVM toolchain, are deployed on the server, the server uses these four optimization toolchains to optimize the source APK of the Android application, and you can get Four target APKs, which correspond to these four optimization tool chains one by one.

For example, the first of the four target APKs is obtained by the server using the maple tool chain to optimize the source APK; the second APK of the four APKs is the server using the Java tool chain to optimize the source APK To; the third of the four target APKs is obtained by the server using the AOT tool chain to optimize the source APK; the fourth APK of the four target APKs is obtained by the server using the LLVM tool chain to optimize the source APK of.

When the server optimizes the APK, in other possible implementation manners, a variety of optimization tool chains can also be combined to optimize the source APK and finally generate a target APK.

For example, the optimized file obtained by optimizing the Maple tool chain in the source APK can be used as the input of the LLVM tool chain, and the target optimized file can be obtained after the LLVM tool chain is optimized.

When the server optimizes the APK, in some other possible implementation manners, the server row may preset an optimization strategy, and select one or more optimization tool chains deployed on the server to optimize the source APK according to the optimization strategy. The optimization strategy includes rules of which tool chains are called by the server application to optimize the files to be optimized in the source APK. The optimization strategy may be input to the server after being specified by the optimizer, or may be a strategy generated by the machine through artificial intelligence (AI) algorithm as the server optimization strategy.

In the optimization method of the embodiment of the present application, the server may add the path information of the target optimization file to the configuration file of the source APK to obtain a new configuration file, and include the new configuration file in the target APK, so that the terminal device can Path information acquisition target optimization file.

Optionally, the server may configure a flag in the configuration file or other files of the target APK, and the flag indicates that the target APK is an optimized APK, including the target optimized file.

In the method of the embodiment of the present application, in some possible implementation manners, after the server optimizes the source APK, the obtained target APK may include files to be optimized in the source APK, files other than files to be optimized, and files to be optimized The target optimization file obtained after optimization. In other words, the target APK may include all the files in the source APK and the optimized target files obtained after optimization.

For example, if the source APK includes a resource file (resource), a configuration file, and a dex file, after the server optimizes the dex file, the obtained target APK may include a resource file, a configuration file, a dex file, and a dex file after optimization Get the file. The dex file is a file to be optimized, and the file obtained after the dex file is optimized is a target optimization file, and the target optimization file may include the optimized machine code.

For example, as shown in FIG. 3, the APK of the Android application released by the developer to the application market includes a resource file, a dex file, and a library file. It should be understood that the APK may also include other related files.

After the server optimizes the dex file and the library file, the target APK obtained may include resource files, configuration files, dex files, library files before optimization, files obtained after optimization of the dex files, and library files obtained after optimization . Among them, the dex file is the file to be optimized, the file obtained after the optimization of the dex file and the library file obtained after the optimization are the target optimization file, the target optimization file may include the machine code obtained by the optimization, the library file obtained after the optimization and the optimization Compared with the library file, the number of instructions is less.

If the dex file and the library file are files to be optimized, after the optimization tool chain in the application market optimizes both the dex file and the library file, the target optimization file corresponding to the dex file and the target optimization file corresponding to the library file can be obtained.

In this case, the target APK sent by the application market to the terminal device may include a file in the source APK, a target optimization file corresponding to the dex file, and a target optimization file corresponding to the library file.

This implementation method enables the terminal device to optimize the files to be optimized in the source APK and execute the target optimized files obtained after optimization by itself even if the optimized files in the APK cannot be directly executed, so that the Android application can be normally started .

In the method of the embodiment of the present application, in some other possible implementation manners, after the server optimizes the source APK, the obtained target APK may include only files other than the file to be optimized in the source APK and the file to be optimized after optimization Optimized files. In other words, the target APK may not include the file to be optimized in the source APK.

For example, the APK released by the developer to the server includes a resource file (resource), a configuration file, and a dex file. Among them, the dex file is the file to be optimized. After the server optimizes the dex file, the target APK obtained may include resources Target optimization files corresponding to files, configuration files and dex files.

Compared with the previous possible implementation manner, this possible implementation manner can reduce the size of the target APK.

In the method of the embodiment of the present application, optionally, before S201, the method may further include: the server receives a message requesting to download the Android application from the terminal device. That is, the server sends the target APK of the Android application to the terminal device after receiving the request to download the Android application from the terminal device.

4 is a schematic flowchart of a method for running an Android application according to an embodiment of the present application. It should be understood that FIG. 4 shows steps or operations of the method, but these steps or operations are only examples, and other operations or variations of the operations in FIG. 4 may be performed in the embodiments of the present application.

S402. The terminal device receives the target APK of the Android application from the server, and the target APK includes the target optimization file obtained by optimizing the file to be optimized in the source APK of the Android application.

Or it can be said that the terminal device downloads the target APK of the Android application from the server.

The server can be understood as an application market. The source APK of an Android application can refer to an APK published or uploaded by a developer to the server. The target APK of the Android application can refer to an APK obtained by optimizing the source APK by the server.

The source APK includes files to be optimized. The file to be optimized may be understood as a file that needs to be optimized, such as a dex file and / or a library file. The target APK includes the target optimized file obtained after the file to be optimized is optimized, for example, the file obtained after the optimization of the dex file and / or library file is the target optimized file. The file to be optimized and the target optimized file may have a one-to-one correspondence.

S404, the terminal device runs the Android application according to the target optimized file in the target APK.

Before the terminal device runs the Android application according to the target APK, a runtime environment capable of directly loading the target optimization file from the target APK should be deployed on the terminal device.

In the method of the embodiment of the present application, since the APK downloaded from the server by the terminal device is optimized, the terminal device does not need to optimize the APK by itself, thereby reducing the burden on the terminal device and improving the user experience.

For convenience of description, in the embodiment of the present application, the target optimization file obtained by the server optimizing the file to be optimized in the source APK is referred to as the first target optimization file.

When the terminal device runs the Android application according to the first target optimization file in the target APK, an implementation manner may include: reading the target optimization file according to the path information of the first target optimization file recorded in the configuration file, and then running the first Target optimization files.

Optionally, the terminal device may first determine whether the APK downloaded by the terminal device from the application market is an optimized target APK, or, the terminal device may first determine whether the APK downloaded by the terminal device from the application market includes the first target optimization file . If so, you can read the first target optimization file and run the first target optimization file.

In the method of the embodiment of the present application, optionally, the terminal device may choose to start the Android application according to the target optimization file in the target APK; or the terminal device may choose to optimize the file to be optimized in the source APK by itself, and optimize it according to its own Get the file to start the Android application.

For example, after the terminal device receives the APK of the Android application from the server, if the APK is an APK that has not been optimized, that is, the source APK released by the developer to the server, the terminal device can optimize the files to be optimized in the APK by itself, and according to Start the Android application with the optimized file. This implementation mode enables the terminal device to normally start the Android application even if it is downloaded from the application market without an optimized source APK.

In some implementations, even if the terminal device downloads the optimized target APK from the server, the terminal device may determine to start the Android application according to the target optimization file in the target APK, or may determine that it has optimized the source APK To optimize the file, and start the Android application according to the file obtained after optimization.

For example, the terminal device may be pre-configured with an execution strategy or downloaded from the server, and the terminal device may determine whether to start the Android application according to the target optimization file in the target APK or optimize the file to be optimized in the source APK by itself. , And start the Android application based on the files you have optimized.

For example, the execution strategy may include the following: the terminal device defaults to start the Android application according to the target optimization file in the target APK; in the case of failing to start or run the Android application according to the target optimization file in the target APK, the terminal device optimization The files to be optimized in the source APK, and start the Android application according to the files obtained after optimization.

In the running method of the embodiment of the present application, in some possible implementation manners, the target APK may include only files other than the file to be optimized in the source APK and the target optimized file obtained through optimization of the file to be optimized. In other words, the target APK may not include the file to be optimized in the source APK.

For example, the APK released by the developer to the server includes a resource file (resource), a configuration file, and a dex file, and the dex file is a file to be optimized. After the server optimizes the dex file, the target APK obtained may include the resource file, Target optimization file obtained by optimizing configuration file and dex file.

In this implementation manner, the download volume of the terminal device is relatively small, so that the download speed can be improved, thereby improving the user experience.

In the running method of the embodiment of the present application, in some other possible implementation manners, the target APK may include a file to be optimized in the source APK, a file other than the file to be optimized, and a first target optimization obtained through optimization of the file to be optimized file.
