Android :: Connecting Two Devices Via TCP Sockets

I've been trying to connect two Android devices (2.1) via TCP sockets.

The vital part of the code:

Server:
ServerSocket serverSocket = new ServerSocket(SERVERPORT);

Client:
Socket socket = new Socket(serverAddr, SERVERPORT);

The weird thing is I can make it work if the client is an emulator, but the same code fails if running both of them on real devices.

The failure in the client side is:

CODE:................

I tried with WIFI and mobile net too, they were in the same subnet both times, INTERNET permission is given, the server is addressed through its real 192.168.. IP. I am planning to change the socket implementation with setCustomSocketImplFactory(). The problem is crucial in the process of implementing MSRP protocol to Android.
