Try this to receive json

 public class MyGcmListenerService extends GcmListenerService {

        private static final String TAG = "MyGcmListenerService";

        /**
         * Called when message is received.
         *
         * @param from SenderID of the sender.
         * @param data Data bundle containing message data as key/value pairs.
         *             For Set of keys use data.keySet().
         */
        // [START receive_message]
        @Override
        public void onMessageReceived(String from, Bundle data) {
            String message = data.getString("message");
            String title = data.getString("title");
            String id = data.getString("id");

            //Log.d(TAG, "From: " + from);
            //Log.d(TAG, "Message: " + message);
  sendNotification(message, title);
     }
        // [END receive_message]

        /**
