Answer 1

The reason behind that may be you have include two different versions for gms. Also if you have included the complete package then there is no need to include the second 'compile 'com.google.android.gms:play-services:7.5.0'' If you need only auth services from google then dont include the complete package it ll exceed 65k methods and duplicacy chances will be there. Include this

compile 'com.google.android.gms:play-services-auth:9.4.0'

and from your code remove

compile 'com.google.android.gms:play-services-auth:9.2.1' compile 'com.google.android.gms:play-services:7.5.0'

Execute it and let me know once.
