socket.io and android not connecting a second time

[ben-hudson]

private Socket socket;

@Override
protected void onCreate(Bundle savedInstanceState) {

    try {
        socket = IO.socket("http://tyr-einsteinium.rhcloud.com/");
        socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {

            @Override
            public void call(Object... args) {
                Log.d(getClass().getCanonicalName(), "Connected to server");
            }

        }).on(Socket.EVENT_DISCONNECT, new Emitter.Listener() {

            @Override
            public void call(Object... arg0) {
                Log.d(getClass().getCanonicalName(), "Disconnected from server");
            }

        });
        socket.connect();
    } catch (URISyntaxException e) {
        Log.e(getClass().getCanonicalName(), e.toString());
    }
}

@Override
protected void onDestroy() {
    socket.disconnect();
    super.onDestroy();
}

It's working fine for me. Where are you calling the socket connection? Can you post the relevant code you used to create the socket?

[FaizVisram]

What kind of class is this? Application, Activity, Fragment?

[ben-hudson]

Its an ActionBarActivity

It may be the same problem with #21.
What happens if you set forceNew option true?

[ben-hudson]

forceNew works for me. Is there anything I need to do in addition to this? Or is the cleanup the same?

[nkzawa]

forceNew option forces to create a new connection every time, it can cause a performance problem.
So it might be better to use Manager directly instead of IO.socket.

manager = new Manager("http://localhost:3000", options);

socket1 = manager.socket("/foo");
socket2 = manager.socket("/bar");

Manager represents a connection, and IO.socket is just a convenient wrapper of it.
Please see the source code for the details.

So basically by using the manager directly I avoid creating a new one each time.

Got it working! Thanks and great library :)

I was also facing the same problem.
You should disconnect the Socket in "ondestroy" method
Example:
onCreate(Bundle savedInstanceState){
Socket.on("foo");
}

onDestroy(){
Socket.off("foo");
}
