Η Google Celebrating them 16's birthday and through a post on her account at Google+ revealed the name in the upcoming version Android, The Android L.
At picture uploaded by Google it looks like a cake, but it does not have candles on its top, but several lollipops. Besides, Google is doing nothing at random, so Lolipops is about the name of the new Android Lolipop
In fact, at the top of the photos there is the question "Why do we put candles on birthday cakes?“. If you try to ask Google (Ok google) it will tell you how the custom started from Ancient Greeks.
