Answer 1

You may want to check this thread which states that you'll get this error when the activity is not exported. Be noted that the activity has to be exported to be accessible from adb.
Also, based from this SO post, you have to add the following to your android manifest: <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> or maybe the problem was that the onTokenRefresh() method was not called when the app was starting. Try calling FirebaseInstanceId.getInstance().getToken() in the MainActivity and see if it works.
