        } catch (MalformedURLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        socket.connect(new IOCallback() {
            public void onMessage(JSONObject json, IOAcknowledge ack) {
                try {
                    tv.setText(json.toString(2));
                    System.out.println("Server said:" + json.toString(2));


                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }

            public void onMessage(String data, IOAcknowledge ack) {
                System.out.println("Server said: " + data);
            }

            public void onError(SocketIOException socketIOException) {
                System.out.println("an Error occured");
                socketIOException.printStackTrace();
            }

            public void onDisconnect() {
                System.out.println("Connection terminated.");
            }

            public void onConnect() {
                System.out.println("Connection established");
            }

            public void on(String event, IOAcknowledge ack, Object... args) {
                System.out.println("Server triggered event '" + event + "'");
            }
        });


        socket.send("Hello Server!");


    }

The method onMessage in IOCallback can get message Server sended by the parameter "String data" If this method never tiggered by the message server send, maybe your connection is not alive

I receiving message at this method 

  @Override
        public void on(String event, IOAcknowledge ack, Object... args) {
            System.out.println("Server triggered event '" + event + "'");
            //it comes with 3 parameters event, acknowledge and args
            //if you want to get args to String try this
              Object[] arguments = args;
            System.out.println("Args"+ arguments[0].toString());
        }

you can check server response at log with socket.io tags
