connection between android and pc application using socket

Question

i want to write an App for Android and a java-program for pc(in my case: windows 8.1) which should communicate with each other using Sockets. My PC would be the server and the phone the client.

My Server code so far:

import java.net.ServerSocket;
import java.net.Socket;

public class TestServer {

    public static void main(String[] Args) {
        Socket socket = null;
        ServerSocket server = null;
        try {
            server = new ServerSocket(4736);
            socket = server.accept();
            System.out.println("Connected");
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
                // TODO
        try
        {
          socket.close();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}

In my android app i now want to create an instance of Socket. What do i have to put in the arguments of the Socket-Constructor? What permissions do i need?

PS:I know that i have to do it in an extra thread.

您需要INTERNET许可，并提供ip和port作为套接字的参数。
