Android Obfuscation file proguard.cfg

1. Proguard Effect
Proguard the ability to obfuscate, compress, and optimize code by removing useless code, renaming the class name, method name, and property name in code to obscure names, similar to JavaScript obfuscation and compression.
Compression and optimization make the APK package smaller after compilation.
Confusion can ensure that the code is hard to read after being recompiled, preventing reverse engineering. This is one of the reasons why we need to Proguard before the app is released.

Reference: http://www.trinea.cn/android/proguard-use/

If packaged with the Eclipse Export command, it is within the <project_root>/proguard folder. It contains the following files:

Mapping.txt represents a comparison of the code before and after the confusion, this file is very important. If your code is confusing and generates a bug, the log hint is a confusing code, and if you want to locate the source code, you can reverse it by mapping.txt.
Dump.txt describes the internal structure of all class files within the APK
seeds.txt lists classes and members that are not confused
usage.txt lists code that is deleted in the source code that does not exist in the APK
