---SOLVED : deleted 2 lines from :app:build.gradle---
compile files('ParseLoginUI/libs/Parse-1.9.1.jar')
compile files('ParseLoginUI/libs/ParseFacebookUtilsV4-1.9.1.jar')
the lib comment here can be interpreted as "you need these 2 statements in your proj.root.build.gradle. Well not true. I had to delete those in order not to get 'dupe zip' errors from proguard.
--Solved--
Upgrade of parseUI library from v3 to v4 went fine til i tried to run proguard within gradle "assembleRelease" task.
Error:
:proguardRelease FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':proguardRelease'.
> java.io.IOException: Can't write [/home/rob/src/CastVideos-android/build/intermediates/classes-proguard/release/classes.jar]
(Can't read [/home/rob/src/CastVideos-android/build/intermediates/exploded-aar/CastVideos-android/ParseLoginUI/unspecified/libs/Parse-1.9.1.jar(;;;;;;!META-INF/MANIFEST.MF)] (Duplicate zip entry [Parse-1.9.1.jar:com/parse/AnonymousAuthenticationProvider.class]))
I checked proguard faqs for "dupe zip" ... I tried to figure out how the dependency tree might be handling a dupe of ./libs/Parse-1.9.1.jar in that library.
IM stuck
