About Android L and features

Android L

Breaking out of the mold from previous releases, Google took to the stage during its Google I/O developer conference to announce a new version of Android, dubbed simply "Android L," which is expected to be released as Android 4.5. The name comes from the Android naming convention that goes in alphabetical order, where L would follow the previous release, KitKat. The difference this time around being that all we are offered is Android L, rather than a true brand name, which will come when the software is released to consumers in the fall of 2014. Android L is in many ways simply a placeholder name as a developer preview.
