AbstractMethodError with Firebase Cloud Messaging

Question

I've just changed our app's GCM out to FCM, and also added OneSignal to it. Followed the guides to the letter, even created a new listener service for processing push notifications.

However even without the listener, whenever I receive a push, the app crashes with the following message:

09-27 14:11:21.483 25361-25361/com.appname.here E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.appname.here, PID: 25361
java.lang.AbstractMethodError: abstract method "android.content.Intent com.google.firebase.iid.zzb.zzae(android.content.Intent)"
    at com.google.firebase.iid.zzb.onStartCommand(Unknown Source)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:620)

I've removed every code from the listener, and even then, this happens.

Did I implement something the wrong way, or am I missing something?

Build.gradle:

The logcat is literally just this entry, nothing else. I'll post the build.gradle for the app module in a moment, I need to remove some proprietary and NDA-covered stuff from it. — fonix232
@FrankVanPuffelen please motivate for this to be added to the documentation. — Richard Le Mesurier

Update the version numbers of the Firebase libararies to be be consistent with the other Google Play Service libraries:

Change:

compile 'com.google.firebase:firebase-core:9.2.0'
compile "com.google.firebase:firebase-messaging:9.0.2"

To:

compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-messaging:9.6.1'
