本文对Android平台下的自定义插件框架的实现做出初步的探索与研究，通过研究Android应用程序的安装与运行原理及其文件系统的结构，以完成插件规范和标准的定义；通过研究Android环境下Java语言动态加载类技术原理，以完成插件程序的加载与操作。与传统应用开发不同，通过引入该插件框架，应用程序的开发可以选择性的将部分功能模块插件化，插件化后的各个模块耦合性进一步降低，可以异步进行开发，各插件的升级更新更加独立而合理。-In this paper, to make a preliminary exploration and research for achieving Android platform custom plug-ins fr a mework, by studying the structure of Android applications to install and run the principle and the file system to complete the custom plug norms and standards　Android environment through research under dynamic loading Java language class technical principles, in order to complete the operation loading plug-ins. Different　the traditional application development through the introduction of the plug-in fr a mework, application development may optionally be part of the plug-in modules, each module further reduces coupling of the plug-in after asynchronously develop, upgrade updating of plug-in more independent and reasonable.
