如何在IDE中看Android java源码

1. 通过分析ADT, 我们知道它找源码是去SDK/platforms/Android-x.x/sources文件夹下的。
2. http://stuffthathappens.com/blog/2008/11/01/browsing-android-source-in-eclipse/
3. 那如何把源码加入到eclipse中去呢？
4. 去phthon老家下载phthon windows版本， 要小于2.6的。安装。
5. 在系统环境path下加;c:/phthonx.x
6. 因为Android源文件不仅仅包含了Java应用，应用框架层，还有底层库，DVM，Linux kernal等其他组件。我们暂时只需要java部分。网上有网友给出的python程序可以把Android源码中的.java文件抽取出来。

8. cmd->运行 python fix_android_sdk.py <android source foler> <android sdk folder>
9. 把导出的java源码放入到相应版本的android sdk/platforms/sources下。
10. 右键点击工程-》build path->link source->browse. 找源码的文件夹，加入后，eclipse会build workspace一下
11. 完成！
