Google has published the monthly user stats for Android operating system adoption, and they show that devices with Android Jelly Bean 4.1 and 4.2 are now the second most common in use, up 3.4 percent to 28.4 percent in April, moving ahead of Ice Cream Sandwich 4.0 which slipped 1.8 percent to a 27.5 percent market share.
Android Gingerbread 2.3 is still the most widely used Android OS in use, although its dominance has slipped, down by 1.7 percent to covering less than 40 percent of the market.
There are still some devices in use that are stuck on older Android versions, with FroYo listing at 3.7 percent and Éclair listing at 1.7 percent. The Android 1.6 Donut OS accounted for just 0.1 percent of all registered users.
Google collect the data from handsets that intentionally visit the Google Play Store during the month, giving an overall view of which OS versions are in regular use.
With Jelly Bean 4.1 and 4.2 continuing to grow, that version of the Android OS should reach the number one position within the next few months, as users finally receive an OS upgrade to their handsets, or more likely users with original Gingerbread devices upgrade to new phones that come with Jelly Bean pre-installed, such as the HTC One and Samsung Galaxy S4.
In the meantime, Google are expected to announce the latest update to the Android OS at the forthcoming Google I/O developer conference, happening later this month. It had been expected we would see a glimpse of Android 5.0, which carries the codename Key Lime Pie, but it now seems likely that the update will be a tweak to the current Jelly Bean OS, Android 4.3
