Android Proguard simple learning

* Configure signature information
* Configure ProGuard to add ProGuard. config = proguard. cfg to proguard.

After the obfuscator is run, the output files are:
Dump.txt
The internal structure of all class files in the pai.apk package.
Mapping.txt
Lists the mappings between source code and obfuscated classes, methods, and attribute names. This file is useful for bug reports after construction, because it translates obfuscated stack trace information into classes, methods, and member names in the source code. For more information, view the decoded stack trace information.
Seeds.txt
List unobfuscated classes and members.
Usage.txt
Code extracted from .apk

? How to handle Android imported packages? There are two types: third-party, and dynamic jar packages with source code. Do you need to set Obfuscation? Currently, no settings are required.
