While trying to write a file SocketException is throwing.
private void openSocket() { try{ multicastSocket = new MulticastSocket(port); multicastSocket.setTimeToLive(2); multicastSocket.setReuseAddress(true); multicastSocket.setNetworkInterface(networkInterface); multicastSocket.joinGroup(groupAddress); System.out.println("----------------Port Opened----------------"); }catch (Exception e) { e.printStackTrace(); Toast.makeText(getBaseContext(), "openSocket!!"+e, Toast.LENGTH_SHORT).show(); } } Log is as follows:
