Firebase Handleintent Abstractmethoderror

When I receive a push notification on Android, I get the below error. I can't really seem to find any information about it. Can anyone help? I am really at a loss. FATAL EXCEPTION

Solution 1:

You should keep the Firebase libraties version and Google play services libraries similar. So update the version numbers of the Firebase libararies to 10.2.1:

Change:

compile'com.google.firebase:firebase-core:10.0.1'compile'com.google.firebase:firebase-messaging:10.0.1'

To:

compile'com.google.firebase:firebase-core:10.2.1'compile'com.google.firebase:firebase-messaging:10.2.1'

Solution 2:

Yout must have every the google play service's line in tha same version

compile'com.google.android.gms:play-services:11.0.1'compile'com.google.android.gms:play-services-maps:11.0.1'compile'com.google.firebase:firebase-core:11.0.1'compile'com.google.firebase:firebase-messaging:11.0.1'

Solution 3:

I just cleaned the project and it worked
