Local code patch updating method and device based on Android platform

Abstract

A local code patch updating method based on an Android platform comprises the steps that a target program is started, targets in executable sub-files for local code updating are configured into various loads in main executable files in an installation pack prior to the target program; memory patch files are loaded to shield the same type of caused program running errors existing in the multiple executable files; a target program is started again, various target types in the executable files are loaded, and other types in the main executable files except the target types are loaded. In addition, the invention further provides a local code patch updating device based on the Android platform, local update of codes in the executable files can be achieved, code snippets required to be updated in the future are not needed to be predicted before code development, and accordingly the flexibility and convenience of code update can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for updating local code patches based on an Android platform. Background technique [0002] In the prior art, in the Android system, only when the code area to be updated is known in advance, the code to be updated can be implemented in the sub-Dex file, and the main Dex file uses reflection calling to call All codes to be updated are partial code update methods currently used, wherein the main Dex file refers to the classes.dex file in the APK (Android Package, Android installation package) file. When the code in the sub-Dex file has a new version, the sub-Dex file is dynamically updated and replaced. [0003] But there is following defective in above prior art: [0004] 1. It is necessary to predict the code fragments that need to be updated in the future before developing the code, and then write the code related to the update into the sub-Dex file. Thi...

Problems solved by technology

[0004] 1. It is necessary to predict the code fragments that need to be updated in the future before developing the code, and then write the code related to the update into the sub-Dex file. This kind of prediction is very difficult;

[0005] 2. The main Dex file calls the code in the sub-Dex file, which can only be executed by means of reflection call, and the execution method is limited;

[0006] 3. The code in the main Dex file cannot be partially updated
