        } catch (MalformedURLException e) {
            e.printStackTrace();
        }
        socketio.connect(new IOCallback() {
            @Override
            public void onMessage(JSONObject json, IOAcknowledge ack) {
                try {
                    Log.e("Server said:" , json.toString(2));
