Reading Tweets via Android

So I'm following this tutorial http://masl.cis.gvsu.edu/2010/10/12/android-dev-tutorial-now-available-on-the-gvsu-itunes-u-portal/ and have had no problems what so ever until now.

On Module 3, the app downloads data from twitter and displays them in a list view. I followed the lecture video and understand everything. However, once I tried it on my own I ran into issues. I even copy and pasted the lecture source code and still can't get it to work.

What I'm wondering, is it my mistake? or does it have to do with some obsolete code, as the tutorial is more than a few years old?

Here's my 2 java classes: http://pastebin.com/g27HrgN3 http://pastebin.com/d7kD0gr4

The app never lists any twitter data like it's supposed to. Here's the app output

here's what I get as output on my environment

As you can tell, I'm new to android programming, a point in the right direction would be great.
