Back in July 27, 2010, The San Francisco Android User Group held an event where Michael Leahy, founder of EGR Software delivered a presentation on real-time app and game development.
He also talked about TyphonRT, Android 2D API, and OpenGL 1.x. It's taken a bit longer than usual to get the video up, but if you're interested in his presentation check out the video below:
