    Hello ,
    I'm new at android\java so be patient :)

    I want to create a small application that send a udp string to my server when I press the button.
    everything is working - but it doesn't seem to send
    this is what I have

    btnAction.setOnClickListener(new View.OnClickListener() {
    @ override
    public void onClick(View v) {

    try {

    String messageStr = "test!";
    int server_port = 1111;
    DatagramSocket s = new DatagramSocket();
    InetAddress local = InetAddress.getByName("My.Public.Server.IP");
    int msg_length = messageStr.length();
    byte[] message = messageStr.getBytes();
    DatagramPacket p = new DatagramPacket(message, msg_length, local,server_port);
    catch (Exception e) {



    whant could be the reason for it?

    Thanks ,
