A full nine months and two versions after it’s initial release Android 2.2 Froyo is clearly the most popular version of Android at the moment. If not the most popular, it is at least the most widely used version.
According to Google, of all the Market-capable Android devices out there, 61.3 percent are running on Froyo. The next most used version is Android 2.1 which is used on 29 percent of devices. So, if you have an Android device, there’s a 90 percent chance that you’re running on 2.1 or 2.2. That’s not bad at all, though it would be a lot nicer if the full 90 percent was on 2.2 given the vast improvements made to the OS between the two versions.
On a less positive note, Gingerbread has a very small share of the market. Android 2.3 and 2.3.3 combined have a total of 1.7 percent of the Android market. It’s sad that the most recent version of the smartphone OS is less used than two of the oldest versions. Android 1.5 and 1.6 have shares of 3 and 4.8 percent, respectively.
Going on to tablets, we can see just how unsuccessful the Xoom has been so far. Honeycomb is one 0.2 percent of Market-capable devices. Maybe that will improve as the OS gets more refined and gains more apps. For now, though it seems Honeycomb is slow to gain traction.
