Google released the latest Android usage stats on Monday. Jelly Bean becomes the most popular Android OS for the first time. It takes 37.9% Android market share(32.3% from 4.1.x and 5.6% from 4.2.x). Ginegerbread is at the second place and it has 34.1% Android market share.
This is a good news to many Android developers as they can use many new features provided in the new system if there are more and more users are using the new OS. Also if Google wants to attract news users, they have to encourage all vendors to adopt the new system on their devices. This time Jelly Bean takes the first place partly due to some OEMs have adopted the new system on their devices.
As Android is open sourced and many different handset device manufacturers are adopting Android systems, there are many different versions of Android on the market and it's very difficult for all the vendors to upgrade their system at the same time. Google is trying to solve this issue so that the new Android can be quickly adopted and unified among different vendors.
