Twit 01 android dev tweets

Performs OAuth using the "signpost" library. Retrieves a number of #AndroidDev Tweets from twitter and displays in a custom list. All REST api requests are done via AsyncTask and apache http client.
:-1: be careful. This is a non-static class, so it'll retain an reference to the enclosing class, which in this case is an Activity.

Given the private inner class is an AsyncTask, you've got a memory leak here ("leaking 'Context'"). Aka, when you rotate your phone, and a new Activity is created (as is the case), your task will still have a reference to the old Activity so it won't be garbage-collected.
