Try this:

class myAsyncTask extends AsyncTask<Void, Void, Void>    {
        Context context;
        myAsyncTask(Context context)    {
             this.context=context;           
        }
        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);
            //Do stuff that you want after completion of background task and also dismiss progress here.
        }
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            //create and show progress dialog here
        }
        @Override
        protected Void doInBackground(Void… arg0) {
            //background task here
            return null;
        }   
    }

and execute like this:

myAsyncTask myWebFetch = new myAsyncTask();
                myWebFetch.execute();

Hope it Helps!!

  • why are you using thread.sleep()?? don't use that and put dialog.show in OnpreExecute method of asynctask. – Armaan Stranger Jul 31 '13 at 12:37
