This evening, Google posted up the official Android distribution numbers. Last month, Jelly Bean creeped past the 50% mark, and this month, it seems that it hasn’t slowed down yet, now on 54.5% of devices up from 52.1%. As for the newest version of Android, Kit Kat (Android 4.4), it appears that it is currently on only 1.1% of devices, a somewhat dismal number, but there’s plenty of time for that number to grow.
Ice Cream Sandwich dropped to 18.6% from 19.8%, Gingerbread to 24.1% from 26.3%, and Honeycomb and Froyo are pretty much done for at this point.
