Android continues to find interesting new applications and problems to solve, both within and outside the mobile arena. Mainlining continues to be an area of focus, as do a number of areas of core Android functionality, including the kernel. Other topics include efficient operation on big.LITTLE systems, support for HiKey in AOSP (and multi-device support in general), and the upcoming migration to Clang for Android builds.
Android continues to be a very exciting and dynamic project, with the above topics merely scratching the surface. For more details, see the Android/Mobile Microconference wiki page.
