Jelly Bean rises to prominence as KitKat comes into view
Few Android users like to acknowledge that dirty little "F" word that's followed Android almost since the beginning. We're talking about "fragmentation," or the fact that Android devices far and wide run a variety of versions of Android. Fragmentation still exists in the Android ecosystem, but it's not nearly as bad as it once was. In fact, over half of all Android devices are now running Jelly Bean.
For that to be true, we need to combine all versions of Jelly Bean out there, including 4.1.x, 4.2.x, and 4.3. The trio of Jelly Bean flavors add up to a 52.1 percent share of the Android market, according to Google's Android Developers Dashboard. That's the good news. The bad news is that most of the those users are running the earliest version of Jelly Bean -- 37.3 percent on version 4.1.x, to be exact, followed by 12.5 percent on version 4.2.x and just 2.3 percent on version 4.3.
The second most popular version of Android at this point is Gingerbread (26.3 percent), followed by Ice Cream Sandwich (19.8 percent), Froyo (1.7 percent), and Honeycomb (0.1 percent).
Android 4.4 (KitKat) will disrupt the balance a bit starting with the Nexus 5 and continuing with the HTC One and other devices that will receive the update within the next few months. However, we suspect Jelly Bean will continue to be the most popular build for at least several more months.
