socket Instant Messaging

rely:

//socket
implementation ('io.socket:socket.io-client:1.0.0') {
    // excluding org.json which is provided by Android
    exclude group: 'org.json', module: 'json'
}

when using it:

Socket socket;
try {
    socket = IO.socket(MyApp.baseSocketUrl));
    socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            Log.d (the TAG, "Call: Socket Connected" );
            LoginSocketBean loginSocketBean = new LoginSocketBean(myApp.getUser_id());
            Gson gson = new Gson ();
            JSONObject jsonObject = null;
            try {
                jsonObject = new JSONObject (gson.toJson (loginSocketBean));
            } catch (JSONException e) {
                e.printStackTrace ();
            }
            Log.d (TAG, "Call: log" );
            socket.emit("user_login",jsonObject);
        }
    }).on(Socket.EVENT_DISCONNECT, new Emitter.Listener() {

        @Override
        public void call(Object... args) {
            Log.d (the TAG, "Call: Socket Disconnected" );
        }

    });
    socket.connect();
} catch (URISyntaxException e) {
    e.printStackTrace ();
    Log.d (TAG, "the onCreate: socket initialization failed" );
}

Above:

1, using the data transmitted to the server emit function (first argument represents the name of the event, as a server to determine the kind of event, the second parameter is the data transmission), where I is the transmitted data JSON format, string may be transmitted directly;

2, using the function on the received data monitor.

3, the socket initialization, using the connect function to connect, disconnect from the network will automatically reconnect the socket reconnection.
