Android :: Network Access With HttpClient Using AsyncTask

I am trying to use a certain wrapper of HttpClient, called HTTPRequestHelper with an associated responseHandler as the basic class for my wrapper to a web service which is implemented as a singleton.

HTTPRequestHelper and samples of usage are described in chapter 6 of "Unlocking Android" published by Manning.

My problem is that invoking both the helper and the handler from a thread started on the main UI thread (either from an AsyncTask or directly) works only sporadically.

Here is the basic setup.

public class APIService { private ArrayList<Something> myThing;
