I use, android support library v4 and v7 in my app. I am using only few
widgets from the support library (not all of them). But in final release
API, 18K functions are included from support libraries. (screenshot
attached) How to reduce them? In attached image, v4 and v7 takes 9k and
6,5k respectively.
Following is my proguard config.
