The problem is you can't create the Handler object in the thread that doInBackground() runs in. I would implement the onPreExecute() method and put your setup code in there. Try moving these lines into the onPreExecute() method:

            URL url = new URL("http://www.example.com/my.xml");
            SAXParserFactory spf = SAXParserFactory.newInstance();
            SAXParser sp = spf.newSAXParser();

            XMLReader xr = sp.getXMLReader();

            MyHandler myHandler = new MyHandler();
            xr.setContentHandler(myHandler);
