java - How to obfuscate only package names using Proguard -

i want rename package name in application com.company1.utils --> com.company2.utils.

how using proguard? don't want apply optimizations in except changing package names.

proguard doesn't have standard option rename packages yet keep simple class names.

you create proguard mapping file manually, lines like:

com.example.myclass -> a.myclass: com.example.myotherclass -> a.myotherclass: 

also command: -applymapping mapping.txt
