混淆生成的文件

1.dump.txt apk包内所有class的内部结构

2.mapping.txt 混淆前后的映射

3.seeds.txt 未混淆的类和成员

4.usage.txt 列出从apk中删除的代码

还原混淆后的代码

GUI 工具：proguardgui 位于 <android-sdk>/tools/proguard/bin/ 目录1) 运行 proguardgui.bat2) 从左边的菜单选择 “ReTrace”3) 在上面的 mapping 文件中选择你的 mapping 文件 ，在下面输入框输入要还原的代码4) 点击 “ReTrace!” 按钮命令行工具：retrace.bat，1）把 mapping 文件和要还原的堆栈信息保存在 stacktrace 文件中2）把这两个文件复制到 retrace.bat 目录下，运行如下命令即可。3）retrace.bat -verbose mapping.txt stacktrace.txt > out.txt
