The latest Android versions numbers are in, and it remains relatively unchanged from last month. Android 2.2 continues to dominate at 63.9 percent, up from 61.3 percent from the previous two weeks or so. Gingerbread builds of Android 2.3 and 2.3.3 are up a tad to 0.8 percent and 1.7 percent, respectively. Android 3.0 Honeycomb remains unchanged at 0.2 percent, which doesn't say much for sales of the Motorola Xoom, which so far is the only device officially running that build. We'll look to see if that changes now that the Wifi-only version of the Xoom is available.
Android 2.1 dropped a couple percentage points to 27.2 percent. Android 1.6 and 1.5 are at 3.5 percent and 2.7 percent.
So Froyo rules, there aren't too many Nexus One and Nexus S devices out there in the in overall scheme of things (they're the only ones officially running Gingerbread so far), and the Xoom and Honeycomb are just getting started. More data's at the source link if you're into that sort of thing. [Android Developer Blog]
