UDP packet is not sent

Here is my class:

public class DatagramClient
{
    private DatagramSocket socket = null;
    InetAddress h;
public DatagramClient() throws SocketException, IOException {
    try {
        socket = new DatagramSocket();
        socket.setBroadcast(true);
        h = InetAddress.getByName("192.168.2.108");

    }
    catch (Exception e) {
        Log.i(Constantes.TAG_LOG, e.getMessage());
    }
}

public DatagramSocket getSocket() {
    return socket;
}

public void setSocket(DatagramSocket socket) {
    this.socket = socket;
}

public void sendPacket(String msg){
    byte[] data = msg.getBytes();
    Log.i(Constantes.TAG_LOG,"Criar DatagramPacket");
    final DatagramPacket packet = new DatagramPacket(data,data.length,h,Constantes.UDP_PORT);
    Log.i(Constantes.TAG_LOG,"Criou DatagramPacket");
    Log.i(Constantes.TAG_LOG,"Enviar packet");
    Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Log.i(Constantes.TAG_LOG,"Run Thread");
                socket.send(packet);
                Log.i(Constantes.TAG_LOG,"Envio dentro da thread");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    });

    Log.i(Constantes.TAG_LOG,"Enviou fora da thread");
}

}

I need send a UDP packet as the string parameter in sendPacket method. When I look at the logcat output I don't see any errors, but the UDP packet is not sent. What is going wrong here?

I added this code and doesn't work:

try {
            thread.start();
            Log.i(Constantes.TAG_LOG,"Executou thread");
        }catch(Exception e){
            Log.i(Constantes.TAG_LOG,"Erro thread.start()"+e.getMessage());
        }

logcat>
