Answer 1

You will need to use a Java socket. Here are examples of using TCP sockets in Java. Here are examples of using datagram sockets in Java.

I strongly encourage you to spend some time learning Java before diving into Java socket programming, let alone on Android.

Answer 2

Use the java.net classes. Below is a simple example using DatagramSockets:

String cmd("my command");
    try {
        InetSocketAddress address = new InetSocketAddress("10.1.1.1", 12350);
        DatagramPacket request = new DatagramPacket(cmd.getBytes(), cmd.length(), address);
        DatagramSocket socket = new DatagramSocket();
        socket.send(request);
    } catch (SocketException e) {

        ...
        }
    } catch (IOException e) {

       ...
        }
    }
