Hi Ulf,
Thanks for your reply,I'm not getting what exactly I need to do,I'm new to android technology,

Problem is server sent data or message i'm getting into
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));

Have tried to set received data like this

protected void onProgressUpdate(String... values) {

StringBuilder sb = new StringBuilder();

for (int i = 0; i < values.length; i++) {


sb = null;

But txtRecMsg is still blank
Please Help

Actually aim is like to control Air conditioner devices on individual user basis instead of remote control user will be able to control Air conditioner parameters through Android device,
So the hardware device which is connected to Air conditioner will be having inbuilt wi-fi ,and Android device will get data and send data through wi-fi from that hardware.
