Answer 1

keep the same version of the firebase-core library and firebase-messaging library by Changing the firebase-messaging library version in build gradle

from:

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:9.2.0'
compile 'com.google.firebase:firebase-messaging:9.2.0'
