AndroidAsync websockets not working

Question

I am using this AndroidSync library by koush to to create websocket (server/client) and transfer data between two android devices. The two devices are connected via wifi(one is Wifi AP and other is connected to it ). I get TimeoutException in client device after 4-5 sec of sending the request. This is what I have done so far..

ServerActivity.java

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_server);

    mSockets = new ArrayList<WebSocket>();
    mAsyncHttpServer = new AsyncHttpServer();
    mWebSocketCallback = new AsyncHttpServer.WebSocketRequestCallback() {
        @Override
        public void onConnected(final WebSocket webSocket, RequestHeaders headers) {
            mSockets.add(webSocket);
            webSocket.send("Welcome Client");
            webSocket.setClosedCallback(new CompletedCallback() {
                @Override
                public void onCompleted(Exception ex) {
                    try {
                        if (ex != null)
                            Log.e("WebSocket", "Error");
                    } finally {
                        mSockets.remove(webSocket);
                    }
                }
            });
            webSocket.setStringCallback(new WebSocket.StringCallback() {
                @Override
                public void onStringAvailable(String s) {
                    Log.d("SERVERTAG",s);
                    Toast.makeText(getApplicationContext(),s,Toast.LENGTH_SHORT).show();
                }
            });
        }
    };

    mAsyncHttpServer.websocket("/",mWebSocketCallback);
    mAsyncHttpServer.listen(Utils.PORT_NUMBER);

    Button sendButton = (Button) findViewById(R.id.sendButtonS);
    sendButton.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View view) {
            for(WebSocket socket : mSockets) {
                socket.send("Server sent a string");
            }
        }
    });

}

ClientActivity.java

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_client);
    mWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);

    //Resolve IP address
    int ipAddress = mWifiManager.getConnectionInfo().getIpAddress();
    String hostAddress = Formatter.formatIpAddress(ipAddress);
    hostAddress = "http://" + hostAddress + ":" +Utils.PORT_NUMBER;
    Log.d("CLIENTTAG", "address is " + hostAddress);

    mWebSocketConnectCallback = new AsyncHttpClient.WebSocketConnectCallback() {
        @Override
        public void onCompleted(Exception ex, WebSocket webSocket) {
            if (ex != null) {
                ex.printStackTrace();
                return;
            }
            webSocket.send("Hello Server");
            webSocket.setStringCallback(new WebSocket.StringCallback() {
                @Override
                public void onStringAvailable(String s) {
                    Log.d("CLIENTTAG",s);
                    Toast.makeText(getApplicationContext(), s, Toast.LENGTH_SHORT).show();
                }
            });
        }
    };
    mAsyncHttpClient = AsyncHttpClient.getDefaultInstance();
    mAsyncHttpClient.websocket(hostAddress, null, mWebSocketConnectCallback);

}

This is what I get in logcat in client device.

I haven't really done socket programming before. Can anyone please help me out here?

Any help is appreciated.

Answer 1

I found the issue, as @jrandaz said the problem was with IP address of server.

Turns out

WifiManager.getConnectionInfo().getIpAddress()

returns device's own IP address not the address of wifi hotspot device to which it's connected. I used 192.168.43.1 which is the default IP address of wifi hotspot in android and it worked.
