Answer 1

I met this problem, too. What you say is not the key.

dependencies {
compile 'com.google.android.gms:play-services-auth:11.6.2'
compile 'com.google.android.gms:play-services-plus:11.6.2'
}
apply plugin: 'com.google.gms.google-services'

This apply plugin: 'com.google.gms.google-services' must at dependencies!
