Answer 1

I downgraded my google play-service dependency from

compile 'com.google.android.gms:play-services:9.2.0' 

to

compile 'com.google.android.gms:play-services:8.4.0' 

which solved this issue for me.

Please refer to the following Stack Overflow link for further description.

Please Note: On upgrading to the latest google play-service
compile 'com.google.android.gms:play-services:9.4.0' it solved this issue as well.

Or you could selectively import certain services that you require, instead of importing all google play services.
