} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();

Log.i("ClientActivity", "C: Connecting...");
try {
socket = new Socket(server, port);
}
catch (Exception ec) {
Log.i("ERRORR", "!!!!###Error connectiong to server:" + ec);
}
// String msg = "Connection accepted " + socket.getInetAddress()
// +
// ":" +
// socket.getPort();
// Log.i("ERRORR", msg);
/* Creating both Data Stream */
try {
sInput = new ObjectInputStream(socket.getInputStream());
sOutput = new ObjectOutputStream(socket.getOutputStream());
} catch (IOException eIO) {
Log.i("ERRORR", "Exception creating new Input/output Streams: " + eIO);
}
Log.i("ERRORR", "CONNECTING TO THE SERVER !!!!!!");
// creates the Thread to listen from the server
