Nearly one year after it was announced, Android 4.1+ powers one out of every four Android devices. The monthly developer dashboard figures are out and it shows that while Jelly Bean accounts for 25% of all devices it trails Android 4.0 Ice Cream Sandwich (29.3%) and Gingerbread 2.3 (39.8%).
Beginning in April, 2013, these charts are now built using data collected from each device when the user visits the Google Play Store. Previously, the data was collected when the device simply checked-in to Google servers. We believe the new data more accurately reflects those users who are most engaged in the Android and Google Play ecosystem.
It’s worth noting that starting in April, Google has changed the manner in which it collects data. Designed to more accurately reflect the active user base, it accounts for how Jelly Bean was able to make such a leap in one month.
