    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.d(TAG, "FCM Token creation logic");

    // Get variables reference
    deviceText = (TextView) findViewById(R.id.deviceText);
    editTextEcho = (EditText) findViewById(R.id.editTextEcho);
    buttonUpstreamEcho = (Button) findViewById(R.id.buttonUpstreamEcho);

    //Get token from Firebase
    FirebaseMessaging.getInstance().subscribeToTopic("test");
    final String token = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Token: " + token);
    deviceText.setText(token);

    //Call the token service to save the token in the database
    tokenService = new TokenService(this, this);
    tokenService.registerTokenInDB(token);

    buttonUpstreamEcho.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Log.d(TAG, "Echo Upstream message logic");
            String message = editTextEcho.getText().toString();
            Log.d(TAG, "Message: " + message + ", recipient: " + token);
            FirebaseMessaging.getInstance().send(new RemoteMessage.Builder(FCM_PROJECT_SENDER_ID + FCM_SERVER_CONNECTION)
                    .setMessageId(Integer.toString(RANDOM.nextInt()))
                    .addData("message", message)
                    .addData("action", BACKEND_ACTION_ECHO)
                    .build());
            // To send a message to other device through the XMPP Server, you should add the
            // receiverId and change the action name to BACKEND_ACTION_MESSAGE in the data
        }
    });
