Answer 1

As far as I know, token will be null only when you try to run your app on emulator on which google play service is not there and when you are using dual email id on you google play store(on you actual device), but only one email id is verified for the usage. Those are the cases which will give you null token and I have already implemented FCM in my new project. So for rest of any cases , token won't be null.
