    {
        protected String doInBackground(Void...arg0) {
            Log.d("DoINBackGround","On doInBackground...");


            try {
                Document doc = Jsoup.connect("http://jsoup.org").get();
                Log.d("info", doc.title());
            } catch (IOException e) {
                e.printStackTrace();
            }
            return "You are at PostExecute";
        }
    }

execute in your activity.java,

    new testAsynch().execute();
