As the exception message told you, you can not change UI in non-UI thread.

AsyncTask.doInBackground is executed in another thread. If you try to update ui, you need to put those code in AsyncTask.onPostExecute.

You can not use findViewById(R.id.editText1); inside doInBackground, because default View is created by main UI thread but doInBackground is in background thread. Then solution is that you can pass GDTNo as String parameter to AsyncTask.

Hope this help!
