Google have updated their Android Developer site with some juicy numbers on Android adoption rates based on the number of active smart devices rocking the mobile OS. Android 4.x Ice Cream Sandwich has had a jump of 3.8-percent over the last month, but in the eight months since its release, it has only been able to take 10.9-percent of the Android OS pie.

These decent gains come from device manufacturers updating their smart devices to Ice Cream Sandwich, as well as new flagship Android-based devices like HTC's One X and Samsung's GALAXY S III. Android 2.3 Gingerbread still remains the top of the heap, with 63.6-percent, with Android 2.2 Froyo behind that with 17.3-percent. Good news is Android 2.3 and 2.2's install base is shrinking, dropping 1-2 points over the last month.

Google get this data based on the number of Android devices that have accessed Google Play within a 14-day period, ending July 2. They use this data to decide how to prioritize the development of their applications' features for the devices that are being used the most by users.
