Google has just updated the pie chart on its Android Developers site that shows just how many Android users are running each version of the mobile OS. The latest stats: 32.4% of users are on the most recent version, Android 2.1. That’s a rise of 5.1 percentage points since mid-April. But the bulk of users are still running earlier versions — 29.4% are on 1.6, and 37.2% are on 1.5.
This data is important to developers because it indicates how fragmented the market is, and which operating systems they should ensure their applications are compatible with. As we’ve noted before, the fact that over two thirds of Android users are still tied to an outdated operating system is a serious problem — for example, anyone who isn’t on 2.1 can’t run the official Twitter app. (Google may address this at its I/O conference later this month).
One other reason this is interesting: Google is now updating this OS pie chart more frequently. There was a four month gap between the previous updates that stretched from January 2010 (before the Nexus One was released) until mid-April. The latest updates came only a few weeks apart.
