Java Android Client Socket not working

Am I missing something. I've checked other posts and have thses set in my manifest.

Whenever I try to create a new socket on Samsung Galaxy Express it never gets past this line.

Socket s = new Socket("10.0.2.2", 4736); 

This is my class for starting a socket in a runnable.

private class SendThread implements Runnable {

    @Override
    public void run() {
        try {
            Socket s = new Socket("10.0.2.2", 4736);       <---never gets past this
            PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(s.getOutputStream())), true);
            out.println(sendString);
            new BufferedReader(new InputStreamReader(s.getInputStream()));
            Log.d(TAG, "sent");
            s.close();
        } catch (Exception e) {
            Log.d(TAG, "error");
            e.printStackTrace();
        }
        Log.d(TAG, "end");
    }

}

Server Socket

private class ReceiveThread implements Runnable {
    private ServerSocket receiverSocket;
    private BufferedReader input;
    private Socket socket = null;

    public void run() {
        try {
            receiverSocket = new ServerSocket(receivePort);
            receiverSocket.setReuseAddress(true);
            while (killConnection == false) {
                Log.d(TAG, "listening");
                socket = receiverSocket.accept();
                this.input = new BufferedReader(new InputStreamReader(this.socket.getInputStream()));
                Log.d(TAG, "Input from server" + input.toString());
                String s = input.readLine();
                //UpdateUi(s);
                socket.close();
            }
            receiverSocket.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Ok yes the server-side socket isn't listening
