Google released Lollipop source code on 4th November 2014.

Android 5.0 for XO-4 is in active development status. Any contribution would be much appreciated.

Currently the graphics are almost working. Developers are welcomed to peek/compile the repositories. 04/12/2014.

  • use Repo to download the Android source from github repositories.
$ repo init -u git://github.com/suyouxin/android_manifest.git -b android-5.0.0-xo4
$ repo sync
  • Note: only engineer build is usable, user build can't be booted since SELinux feature hasn't been adapted.
