           loadControls();
           getPassingValue();


            ParserMethod parserMethod=new ParserMethod();

Using AsyncTask.. just like below.. code is not exactly right.. its just to give an idea..

classs backgrnd extends Asynctask{

protected object onPreExecute(){
//display dialog
}

protected object doInBackgroung(Object... arg){
//fetch data
}

protected object onPostExecute(Object result){
//dismiss dialog
}
}
