Sadly the way you do things has changed since then though. I remember doing android development in the 2.3.1 days, and the method of doing dialogs has transformed into fragments since then, so although my old code I wrote back then will run and work, it isn't the recommended way. Nor are the UI guidelines I followed back then. I appreciate that things change (like the UI guidelines every year apparently!!) but if a clear roadmap was laid out back then, it would have saved a lot of time.
