Available videos of Android sessions at Google I / O 2012 conference

Google posted in open access to YouTube 29 video presentations of speakers from the last Google I / O conference, which are devoted to the development of Android. Of course, there is a video about what was beautifully announced earlier - like “What's new in Android?” - but there are three other channels:

• Google I / O 2012 - Design
• Google I / O 2012 - Develop
• Google I / O 2012 - Distribute

with long — fifty minutes — first-hand videos look extremely valuable.
