Android can't extend Firebase Messaging Service

Question

I am trying to implement Firebase Cloud Messaging in my application, I had implemented all settings to use this service, but when I try to extend FirebaseMessagingServ

Answer 1

If you want to use messaging, you have to add the messaging module. Right now you only added the core module.

So go ahead and include

compile 'com.google.firebase:firebase-messaging:9.4.0'

All the available modules can be found at the bottom of https://firebase.google.com/docs/android/setup
