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。

"""Modifies the Android SDK to build Android Scripting Environment.
This script compiles android.os.Exec from the Android source and adds the
class to the Android SDK android.jar. In addition, it copies the source files
into the SDK so that they can be browsed from Eclipse.
In order to use this script, you must have download the Android source and
installed the Android SDK.
