Nearly two-thirds (64.6%) of all Android devices run Android 2.2 or Froyo, and another 21.2% run Android 2.1 or Eclair, according to the latest data from Android Developers.
Last time we've looked at this data, Android 2.3/2.3.3 or Gingerbread was just a blip on the radar, but now it's running on a respectable 9.6% of all Android devices.
For Android developers, the current state of affairs means that they can pretty much forget about supporting now obsolete versions of Android -- 1.5 and 1.6 -- which are now present on a very small number of devices. However, as far as platform fragmentation goes, the situation is about to get ugly: Eclair is still widely used, Froyo isn't going anywhere, and Gingerbread is slowly gaining momentum.
Add to that two versions of Honeycomb (3.0 and 3.1), the Android flavor aimed specifically at tablets, and you've got a lot of Android variants to support. Luckily, the upcoming Ice Cream Sandwich (4.0), slated for a late 2011 release, will consolidate Honeycomb and the "regular" Android variants into one version, which should reduce confusion and ease the fragmentation issues of Google's mobile platform.
