i solved exact problem today , stumbled onto unanswered question chance during process.

first, ensure you've setup firebase android documented here: https://firebase.google.com/docs/android/setup. then, make sure compiling latest version of firebase apis (9.2.0) , google play services apis (9.2.0) using. gradle dependencies this:

dependencies {     ...     compile 'com.google.android.gms:play-services-location:9.2.0'     compile 'com.google.firebase:firebase-core:9.2.0'     compile 'com.google.firebase:firebase-auth:9.2.0'     compile 'com.google.firebase:firebase-messaging:9.2.0' }

hope helps!
