Difference between proguard-rules.pro and proguard.cfg

Question

I am learning and implementing proguard for very first time. I have seen some examples and add following code in proguard-rules.pro file, but there is also 1 more file named proguard.cfg.

I have tried to google this but unable to understand the difference between proguard.cfg and proguard-rules.pro file.

I have added following in proguard-rules.pro file but what should i add in proguard.cfg file

Answer 1

You have to write your proguard commands inside proguard-rules.pro. You can find this file inside your project as

YourProject -> app -> src-> proguard-rules.pro

Inside another file proguard.cfg you have to-do nothing.
