aosp-devs.org February Newsletter

Welcome to the second aosp-devs newsletter, keeping you up to date with things happening in the AOSP developer community.

Perhaps the most important thing to mention is that we held our first AOSP devroom at FOSDEM. We believe it was a great success! The recordings are now available on our new YouTube channel: @aosp-devs. Enjoy watching!
