Android 4.x "Ice Cream Sandwich" is making gains, though Gingerbread still takes the lion's share, according to a snapshot of data provided to Android developers.
Ice Cream Sandwich (ICS) had about a 2.9 percent share and Honeycomb had more than a 3 percent share, according to Android Developers, which describes the data as "the relative number of active devices running a given version of the Android platform."
ICS started appearing in devices only toward the end of last year.
The Web site says the data can help developers "understand the landscape of device distribution and decide how to prioritize the development of your application features for the devices currently in the hands of users."
Android 2.x Gingerbread was just a little shy of 70 percent.
A year earlier (March 17, 2011), Android 2.2 was on top and Android 3.0 at a trifling 0.2 percent.
In an introduction to a historical distribution chart, the Android Developers page illustrates compatibility by showing versions "stacked on top of each other"--what is sometimes referred to less charitably as fragmentation.
A chart on a Motorola support page mirrors the staggered rollout of Android on various devices. For example, Motorola's newest tablet the Xyboard (aka, "Xoom 2") currently runs Android 3.2.2 but won't see ICS until the third quarter of 2012.
