Google I/O 2012 has come and gone, but the team over in Mountain View has some new goodies to share with those who couldn't make it out this year. The Android developers team has just posted a huge playlist of 28 videos known as the Android Sessions. Nearly all of these videos are a full hour long, so any Android developer wanting to catch up with all of the news from I/O should block off a lot of time on his or her calendar — and that's not even including the more consumer-focused keynote presentations. The videos touch on a wide variety of topics, including marketing, monetization, security, design, and game development. Sadly absent is any dedicated session on tablet development — with the Nexus 7 coming soon, we're hoping to see Android developers take a stronger interest in building apps for the larger screen. Nonetheless, it's quite a collection of information and you can view the entire playlist right here.
