So the Jelly Bean device percentage may appear to be growing, even though it is simply a larger part of a smaller pool of users.
That being said, the most substantial change for Google's numbers appears to be the jump in Android 4.1 users. And other Android platforms, such as Donut (remember that one?) and Eclair, hardly budged.
Gingerbread took a dip from about 44 percent of Android usage to just under 40 percent. When you combine the numbers for users of Android 4.0 and 4.2, Android 4.0 now dwarfs Gingerbread under Google's new counting regime.
All told, Android 4.0 and up accounts for 54.3 of the total Android base, compared to less than 40 percent for Gingerbread. In March, the numbers were far closer at 45.1 percent for Android 4.0 and up versus 44.2 percent for Gingerbread.
What about Honeycomb?
Intriguingly, users of Honeycomb, the early Android OS for tablets, practically disappeared under the new counting method. Honeycomb dropped from 1.2 percent of Android users in March to a measly 0.2 percent as of early April.
Honeycomb was Google's first tablet-specific version of Android and was more of a stop-gap solution to help manufacturers compete against the iPad. It wasn't until Android 4.0 Ice Cream Sandwich, and arguably 4.1 Jelly Bean, that Android became a viable platform for tablets.
This decline for Honeycomb, combined with Google's new counting method, suggests that while Honeycomb devices are out there, they are not seeing much use.
