I think using an AsyncTask is better. On one hand, it's just simpler to implement. On the other hand, it's built in Android and you can be 100% it's supported and the way Android was designed to work. So, rather than using a handler and multiple threads, I find it simpler to display the loading dialog in the onCreate() method, do all the work in the doInBackground() method of the AsyncTask extending class and dismiss the dialog in the onPostExecute(). I don't know about you, but I find it a lot nicer.
