Marakana released screencasts of their three day Android Bootcamp from February 2012. The videos are HD and great quality. Marko iteratively develops a twitter-like app for Android, taking you along every step of the way. While from early 2012, they show all the basics for a beginner in a fully integrated way. There is also a support forum for little glitches as these videos slowly deviate from the latest Android SDK.
