Indeed! Why, one of the major benefits of using HttpClient instead of barebones java.net methods is that it makes it easy to move all the HTTP waiting -out- of the UI main thread.
See, for example, how the authors of "Unlocking Android" have done this in the sample code for chapter 6 at http://code.google.com/p/unlocking-android/ . See especially the class HTTPRequestHelper in HTTPHelperForm.java in NetworkExplorer, since this class 'wraps' HttpClient. Of course, to get a full explanation of how this separation works, you need to buy and read the book;) NB: their approach is noticeably different from Mark Murphy's solution. They use the Looper and Handler, which they call the "Swiss- Army knife" of threading in Android. This approach may appear a little dated compared to AsyncTask, but at least this way you learn to use the Swiss-Army knife, instead of becoming dependent on AsyncTask. One should expect the Swiss-Army knife to be more widely applicable than AsyncTask. Besides: it is a good exercise to rewrite it to use AsyncTask in place of Looper/Handler or vice versa.
