i updated the project to use sdk 21 corresponding to 5.0 lollipop on my phone. I noticed androidmanifest.xml was not auto added to git file list. This is after upgrading to use 1.0 version of android studio.  The change to remove proguard was done. That was detected though. I did not add the change noted by this guy though "
Then you must be using runProguard somewhere. It was renamed to minifyEnabled. ﻿"

Also noticed the gradle build files were not in sync with minsdk version specified in manifest.
