Udacity - Android Development for Beginners

I have been getting prepared for the Google Developer Group - Part 2 Android Development, so I spent most of the day reviewing the first Udacity course:

I spend about six hours working on this with a few breaks but still have quite a ways to go. I was hoping to review the whole course before the meetup tomorrow but was not able to get it done. I still plan to continue working on this since the second series builds on top of this first sequence.
