PROGUARD ON ANDROID STUDIO JAVA APPLICATION

hello, I need to correctly implement the proguard function within an android app.

from the informations in my possession, proguard is able to obfuscate the java libraries and java code

in the attached file you will find an example of android studio app (java) called "freelancerTest.rar " on which I would like to apply the proguard function

my goal is to blur:

- the java libraries of "mainactivity " and "mainactivity2"

- the java code of "mainactivity " and "mainactivity2"

- the all comments

- the manifest.xml

- the xml layout


at the end of the work on your part I would need the same project available but with the new lines of code concerning proguard implemented and a very short explanation



At the moment the result of decompiled apk file is as showed in the file "radme"

thanks
