[0060] The present application provides an application tailoring method, system and related devices for a HarmonyOS lightweight system, which are used to reduce the space occupied by application installation packages in the HarmonyOS lightweight system and improve the installation efficiency of application installation packages.

[0061] It should be noted that the application tailoring method for a HarmonyOS lightweight system provided in this application can be applied to a terminal as well as a system or server. For the sake of convenience, this application uses a terminal as the execution subject for example.

[0062] See also Figure 1 , this application first provides an embodiment of an application tailoring method for a Hongmeng lightweight system, which includes:

[0063] S101. Obtain an installation package for the application to be installed, where the application installation package is an installation package suitable for the Hongmeng lightweight system;

[0064] HarmonyOS's lightweight system features a microkernel architecture, low power consumption, high performance, and multi-tasking scheduling. It is suitable for a variety of embedded devices in areas such as smart homes, smart wearables, and the Industrial Internet of Things. It is a lightweight implementation of the HarmonyOS system for resource-constrained scenarios. HarmonyOS is typically used for resource-constrained terminals, such as some IoT terminals (such as POS terminals) and low-power chips, so the corresponding application installation packages have special features.

[0065] There are many ways to obtain the application installation package, such as downloading it from a designated software repository, reading a pre-stored application installation package file from local storage, or obtaining it from a server via network transmission. The obtained application installation package is an installation package for the HarmonyOS lightweight system. It is a compressed file that may contain application code, configuration files, and other related resources.

[0066] S102: Calling a tailoring script to decompress the application installation package and delete the bytecode files in the application installation package, and compressing the installation files obtained after the decompression and deletion operations into a new application installation package;

[0067] The various codes and resource files contained in application installation packages make them relatively large. HarmonyOS Lightweight OS primarily runs on terminals with limited resources such as memory and storage. Installing a complete application installation package on a terminal equipped with HarmonyOS Lightweight OS will occupy a significant amount of file system resources during installation, impacting the normal operation of the system and other applications. By trimming the application installation package, unnecessary portions such as unused code and redundant resources can be removed. This reduces the size of the application installation package and its use of terminal resources while ensuring the normal operation of the application's core functions. This allows the application to run stably and efficiently on resource-constrained terminals.

[0068] The trimming script is a pre-written program code that can be written in a variety of programming languages, such as Python, C or Java, according to the developer's choice and the support of the system environment. The trimming in the trimming script in this application is mainly aimed at deleting files of specific file formats in the application installation package. By calling the trimming script, specific processing operations can be performed on the application installation package, including decompressing the obtained application installation package, deleting the bytecode (bc) file in the decompressed installation file, and recompressing the deleted installation file to obtain a new application installation package. The memory usage of the new application installation package will be smaller than that of the original application installation package, and after processing according to the preset trimming script, it does not contain the deleted bytecode files, which is more suitable for terminals equipped with the Hongmeng lightweight system.

[0069] S103. Install the new application installation package into the terminal equipped with the HarmonyOS lightweight system.

[0070] After the new application installation package has been processed by the tailoring script, it will be transmitted to the terminal equipped with the HarmonyOS lightweight system via a specific transmission protocol, such as the TCP / IP-based file transfer protocol or the HTTP / HTTPS-based file download method. Then, according to the installation mechanism provided by the HarmonyOS lightweight system, the new application installation package will be installed. During the installation process, the HarmonyOS lightweight system will decompress the files in the application installation package to the designated directory of the terminal, perform configuration and initialization operations, and enable the application to start and run normally on the terminal.

[0071] In this embodiment, the application installation package to be installed is deleting the bytecode files in the application installation package through a tailoring script, and then recompressing the deleted files to obtain a new application installation package. By using the tailoring script to identify the file format and delete the bytecode files in the application installation package, the application installation package can be effectively tailored, reducing the application installation package's consumption of file system resources in the HarmonyOS lightweight system and improving installation efficiency.

[0072] In the above step S102, before calling the cropping script to perform the cropping operation on the bytecode files in the application installation package, the application installation package needs to be decompressed. Figure 2 , Figure 2 This is an embodiment of decompressing an application installation package in the application tailoring method of the Hongmeng lightweight system provided in this application, and the embodiment includes:

[0073] S201, calling the tailoring script to create a temporary folder, and decompressing the application installation package to the temporary folder to obtain the installation file;

[0074] The cropping script has the function of creating a temporary folder. Before performing decompression, the cropping script will open up an independent space in the project, namely the temporary folder in this application. The temporary folder is used to temporarily store the decompressed files to prevent other files from interfering with the application installation package during the decompression process. After the processing is completed, the temporary folder will be deleted.

[0075] When decompressing an application installation package, you can do so in steps. This can more efficiently manage system resources and avoid memory shortages or performance degradation caused by decompressing a large amount of data at once. First, the tailoring script creates a first temporary folder and decompresses the application installation package into it. Based on the compression format of the application installation package, such as ZIP or RAR, the tailoring script uses the corresponding decompression algorithm and tools to extract the files and folders within the application installation package and place them into the first temporary folder. After decompression is complete, you will obtain a zap-formatted installation package in the first temporary folder. The tailoring script then creates a second temporary folder. The second temporary folder serves a similar purpose to the first temporary folder, temporarily storing the decompressed files from the zap-formatted installation package. Finally, the tailoring script performs the decompression operation again, releasing all files and folders within the zap-formatted installation package into the second temporary folder to obtain the installation files.

[0076] S202: Call the trimming script to delete the bytecode file in the installation file.

[0077] When a temporary folder has been created by the cropping script and the application installation package has been decompressed to obtain the installation file, the cropping script is called to crop the installation file. The cropping script will determine whether it is a bytecode file based on the extension of the installation file. For files with a bytecode extension, the cropping script will delete it from the temporary folder. In some specific application scenarios, the operation of the application may only depend on the js file, so the bytecode file is redundant. By deleting these bytecode files, the size of the application installation package can be significantly reduced, thereby improving the deployment efficiency of the application on the terminal, reducing the storage space occupied, and may also improve the loading speed and running performance of the application, preparing for the subsequent installation of the installation file to the terminal of the HarmonyOS lightweight system.

[0078] In this embodiment, a tailoring script creates a temporary folder, decompresses the application installation package into the temporary folder, and obtains the installation files, reducing interference from other files during the decompression process. The tailoring script deletes the bytecode files in the installation files, reducing the size of the application installation package, improving deployment efficiency, and reducing space usage, providing a foundation for subsequent installation of the installation files on HarmonyOS lightweight system terminals.

[0079] In the above S202, the tailoring script is called to delete the bytecode file in the installation file. Figure 3 , Figure 3 This is an embodiment of recursively deleting bytecode files in the application tailoring method of the Hongmeng lightweight system provided by this application, and the embodiment includes:

[0080] S301, calling the clipping script to traverse the file directory of the temporary folder;

[0081] The temporary folder contains the decompressed installation files, which may contain multiple subfolders and many different types of files. By traversing the directory, the trimming script can identify the paths and names of the files and folders, constructing a detailed list of the file structure, providing a basis for subsequent file deletion operations.

[0082] S302: According to the file directory, call the trimming script to recursively delete the bytecode file.

[0083] After obtaining the complete directory information for the temporary folder, the trimming script is called again to recursively delete all bytecode files. During recursive deletion, the trimming script not only processes the bytecode files in the temporary folder's root directory, but also enters each subfolder, checking the file extension one by one. If a file has a .bc extension, it is removed from the temporary folder.

[0084] In some specific embodiments, after the tailoring script is called to process the application installation package, a deletion log is recorded and the space occupied by the new application installation package is displayed. The following is a detailed description:

[0085] After the cropping script is called to decompress the app installation package and delete bytecode files, it will record detailed information about the files deleted during the operation, including the full path, file name, file type, and deletion time, forming a deletion log to facilitate subsequent tracing and troubleshooting. After the cropping is complete, the total size of all remaining JS files is calculated and converted to units such as bytes, kilobytes, or megabytes to display the space usage of the new app installation package, thereby evaluating the effectiveness of the cropping operation.

[0086] In this embodiment, when calling the cropping script to delete bytecode files, the system first traverses the temporary folder's file directory and then recursively deletes the installation files in the temporary folder, deleting only the bytecode files. This reduces the size of the installation package and improves application execution efficiency. Recursive bytecode file deletion reduces the problem of bytecode files remaining in the temporary folder, achieving effective cropping. Furthermore, a deletion log is recorded during the cropping process to facilitate subsequent tracing. After obtaining a new application installation package, the space usage of the new application installation package is displayed, making it easier to understand the cropping effect.

[0087] Before calling the tailoring script, you also need to adjust the parsing mode of the meta-capability cross-platform execution environment ACE in the Hongmeng lightweight system and call the corresponding tailoring script according to the parsing mode. Figure 4 , Figure 4 Another embodiment of the application tailoring method for the Hongmeng lightweight system provided in this application includes:

[0088] S401. Fix the parsing mode of the meta-capability cross-platform execution environment ACE in the Hongmeng lightweight system from the dynamic parsing mode to the js parsing mode;

[0089] The meta-capability cross-platform execution environment (ACE) is used in HarmonyOS to support application execution. It has multiple parsing modes, including dynamic parsing mode, which allows for flexible selection of the appropriate parsing method for files in application installation packages at runtime based on different scenarios. In HarmonyOS, the ACE parsing mode is fixed from dynamic parsing mode to JS parsing mode, meaning that ACE can only use JS parsing mode to parse application installation packages.

[0090] S402: Call a cutting script adapted to the js parsing mode to decompress the application installation package and delete the bytecode files in the application installation package.

[0091] Since ACE's parsing mode is fixed to JS parsing mode, a tailored script must be called to match it. Once the tailoring script is called, it will identify the JS file and, based on the compression format of the application installation package, use the appropriate decompression algorithm and tools to decompress the JS file. The bytecode file is not used and is deleted by the tailoring script. Finally, the JS file is compressed again to form a new application installation package.

[0092] In this embodiment, the dynamic parsing mode of the HarmonyOS lightweight system meta-capability cross-platform execution environment ACE is fixed to the js parsing mode, so that ACE only parses js files, and then calls the tailoring script adapted to the js parsing mode to identify and decompress the js files in the application installation package, delete the bytecode files, reduce the occupancy of unnecessary files, and improve the targetedness and operating efficiency of the parsing.

[0093] After obtaining a new application installation package, a pre-installation test will be performed on the new application installation package. Figure 5 , Figure 5 This is an embodiment of the pre-installation test in the application tailoring method of the Hongmeng lightweight system provided by this application, which includes:

[0094] S501, calling the simulator to perform a pre-installation test on the new application installation package, and judging whether the pre-installation test is successful based on the test result;

[0095] The simulator can simulate the operating environment of a terminal equipped with HarmonyOS Lightweight, including the hardware configuration and software version of HarmonyOS Lightweight. By calling the simulator, new application installation packages can be installed and tested without using a real terminal, which can save testing costs and time and improve the success rate of new application installation packages.

[0096] When attempting to install a new application package in the simulator, the simulator will simulate the conditions of a real terminal and check the file integrity of the installation package, its compatibility with the HarmonyOS lightweight system, and whether any errors occur during the installation process. For example, it will check whether the files in the installation package are damaged, whether necessary dependency files are missing, and whether there will be conflicts with existing software or configurations of the HarmonyOS lightweight system.

[0097] If the installation completes successfully without any errors, and the installed app launches and runs normally, a test result may be generated indicating that the pre-installation test is successful. Conversely, if problems such as file decompression failure or system conflicts occur during the installation process, preventing the app from installing or running normally, the test result will indicate that the pre-installation test failed.

[0098] S502. If yes, install the new application installation package into the terminal equipped with the Hongmeng lightweight system.

[0099] If the pre-installation test is successful, it means that the new application installation package can be installed and run normally in the simulated HarmonyOS lightweight system environment, and has the basic conditions for deployment to a real terminal. At this time, the new application installation package can be transferred to a real terminal equipped with HarmonyOS lightweight system, and the installation program can be launched on the terminal to install the application installation package.

[0100] In some specific embodiments, after the pre-installation test is determined to have failed based on the test results, other processing may be performed, as described in detail below:

[0101] If the pre-installation test fails, this indicates a possible error in the new app installation package. The package will no longer be transferred to the device running HarmonyOS Lite, and an error message, such as "Files are missing from the app installation package," may be generated. This error message allows users to selectively check for potential issues within the app installation package. Users can also browse and delete logs to determine if a problem occurred during the editing process, allowing them to make adjustments.

[0102] In this embodiment, before deploying a new application installation package to a terminal running the HarmonyOS Lightweight system, a pre-installation test is performed on the new application installation. The new application installation package is further inspected and verified, and different measures are taken for the new application installation package based on the failure or success of the pre-installation test. The pre-installation test can identify and resolve potential problems in the new application installation package in advance, improving the reliability of the tailoring and the success rate of the application installation package installation on terminals running the HarmonyOS Lightweight system.
