title: Remove external Library with Android Studio? ( not working)
body: <p>I am trying to remove a support library in android studio, I only want to use one however someone another two got added.( i think maybe they are part of some jars I added? ) I dont know but i cant delete them and they keep re generating. When I click on module settings and the minus sign they just regenerate again. I want only ONE support library yet there are three. can anyone tell me HOW to delete them? I keep getting this error : Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.</p>
