Firebase cloud messaging `onMessageReceived` not being called?

Question

I'm testing Firebase cloud messaging. I have the following class

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.d("From: ", "From: " + remoteMessage.getFrom());
    }
}

My app does generate a token for my device, and I am testing this from the Firebase console. When I send a test message from the Firebase console I get the following messages

03-03 18:16:34.638 12091-12871/com.rev.future D/FA: Logging event (FE): notification_receive(_nr), ..............
03-03 18:16:34.672 12091-12871/com.rev.future D/FA: Logging event (FE): notification_foreground(_nf), ...............
03-03 18:16:34.690 12091-12871/com.rev.future D/FA: Connected to remote service
03-03 18:32:24.462 12091-15272/com.rev.future D/FA: Logging event (FE): user_engagement(_e),..........
03-03 18:32:24.534 12091-15272/com.rev.future D/FA: Connected to remote service

But I never see the message "From: " which makes me believe that the onMessageReceived is not being called

Why is onMessageReceived not being called when I send a message to my device?

EDIT: I am also adding my Manifest

Answer 1

The declaration of the messaging service in the manifest is missing the intent filter:

<service
    android:name=".MyFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

For reference, see the setup instructions.
