Answer 1

The device token is generated when the app first connects, this token must then be stored in your database, and replaced if a new token is assigned

public class MyAndroidFirebaseInstanceIdService extends FirebaseInstanceIdService {

    private static final String TAG = "MyAndroidFCMIIDService";

    @Override
    public void onTokenRefresh() {
        //Get hold of the registration token
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        //Log the token
        Log.d(TAG, "Refreshed token: " + refreshedToken);
    }
    private void sendRegistrationToServer(String token) {
        //Implement this method if you want to store the token on your server
    }
}
