private void handleNotification(String message) {
        if (!NotificationUtils.isAppIsInBackground(getApplicationContext())) {
            // app is in foreground, broadcast the push message
            Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
            pushNotification.putExtra("message", message);
            LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);

            // play notification sound

You can send a Broadcast message.

In your service:

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
      Bundle bundle = new Bundle();
      bundle.putString("msgBody", remoteMessage.getNotification().getBody());

      Intent new_intent = new Intent();
      new_intent.setAction("ACTION_STRING_ACTIVITY");
      new_intent.putExtra("msg", bundle);

      sendBroadcast(new_intent);

      //other code
    }

In your activity:

public class MainActivity extends AppCompatActivity {

    private BroadcastReceiver activityReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            TextView textview = (TextView) findViewById(R.id.textview);
            Bundle bundle = intent.getBundleExtra("msg");
            textview.setText(bundle.getString("msgBody"));
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        if (activityReceiver != null) {
           IntentFilter intentFilter = new  IntentFilter("ACTION_STRING_ACTIVITY");
           registerReceiver(activityReceiver, intentFilter);
        }
    }
}
