        super.onNewToken(s);
        FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

        String tokenRefresh = FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken();

        if (user != null){
            updateToken(tokenRefresh);
        }

    }

    private void updateToken(String tokenRefresh) {
        FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
        DatabaseReference ref = FirebaseDatabase.getInstance().getReference("Tokens");
        Token token = new Token(tokenRefresh);
