深海游弋的鱼 – 默默的点滴

在用Eclipse 调试程序的时候，一旦发生异常，往往在回退栈里面提示找不到源代码.

如下图所示

网上搜索了一下，发现一个 fix_android_sdk.py 脚本，可以提取完整的java 文件到SDK 目录，尝试了一下，还是蛮有用的，可惜就是源代码只能看，不能设置断点。这个是用来编译ASE的一个脚本，里面的部分涉及到ASE的部分我们是用不到，并且也没法用的，所以被我万恶的删除了。

1.首先要下载完整的Android源代码，建议下载一下，说不定哪天就用上了。

对于以前的脚本进行了修改，然后现在可以判断当前的Android 的源代码版本了，如果定义过 "ANDROID_SDK_ROOT"环境变量的话，会使用环境变量中的值拷贝到制定的目录，比如Android 4.1.2 的源代码，现在可以拷贝到 Android-16 目录下面了，不需要再从android-1.5 下面拷贝出来了。下面贴上最新的源代码脚本，供各位参考。
