For PennApps Mobile 2011, I was invite to present a tech talk on how to get started with Android development. The talk gave a general overview of what Android was, how the app layers worked, what you needed to get started, a live/follow-along setup+Hello World demo, a small stopwatch app demo, the basics of debugging, and then finally next steps for app publishing. Finally, the talk ended with a quick blurb of Beats as an example of what your project could become. Here are the links and slides.
