Problems solved by technology

[0003] The process of installing the Dex file to the device is very complicated. If the Dex file is too large, the application may not respond. In this case, you need to use the ProGuard tool to reduce the size of the Dex file.
In addition, due to the limitation of DalviklinearAlloc, when the Dex file requests a large amount of memory, the application may crash; specifically, DalviklinearAlloc is a fixed-size buffer, for example, for the system Android 2.2 and 2.3, the size of the buffer is 5MB, For Android4.x, the size of the buffer is increased to 8MB or 16MB; in the process of starting and running the application, the system will run the dexopt process to prepare for the operation of the application in the current model, and the dexopt process needs to use DalviklinearAlloc To store the method information of the application, when the number of method information exceeds the buffer size, it will cause the dexopt process to crash, and the application cannot run normally

Abstract

The embodiment of the invention discloses an application program running method and device. The method comprises the steps that APK method number information and smali file information corresponding to the APK method number information are obtained from APK file information; for APK file information with APK method number information exceeding a preset APK method number information threshold value, small file information corresponding to the APK method number information can be distributed to a plurality of dex folders based on the APK method number information threshold value, and the APK method number information corresponding to the small file information included in each dex folder is smaller than or equal to the APK method number information threshold value; furthermore, the plurality of dex folders are signed to generate an APK. According to the method, the APK can be dynamically modified, so that the method number information is prevented from exceeding the limit.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an application program running method and device. Background technique [0002] Dex files are executable files on the Android platform (Dalvik virtual machine), which are equivalent to exe files on the Windows platform. Each application installation package (Android application package, APK) has a Dex file, which includes the application (Application, APP) all the source code. [0003] The process of installing the Dex file to the device is very complicated. If the Dex file is too large, the application may not respond. In this case, you need to use the ProGuard tool to reduce the size of the Dex file. In addition, due to the limitation of DalviklinearAlloc, when the Dex file requests a large amount of memory, the application may crash; specifically, DalviklinearAlloc is a fixed-size buffer, for example, for the system Android 2.2 and 2.3, the size of the buffer ...
