San Francisco Android User Group held an event on June 29th, 2010 with Justin Mattson from Google who not only re-delivered his Google I/O talk titled "Casting a wide net: how to target all Android devices", but also expanded it with the material that he had to cut for time at the I/O. Justin also answered a number of questions from the audience.
