Android 2.3 or Gingerbread is installed on 54.9% of all Android devices, while Android 2.2 or Froyo is installed on another 30.4% of all Android devices, which makes Android perhaps the least fragmented it’s ever been.
According to the latest data from Android Developers, out of all the older and now obsolete Android versions only Android 2.1 or Eclair has a significant market share – 8.5%, while earlier versions have less than 2% put together.
Of course, this almost ideal situation – given how badly the Android platform has been fragmented at certain points in the past – won’t last long. The newer versions – Android 3.0, 3.1, 3.2 and 4.0 are looming behind the corner, and most upcoming Android devices run or at least support one of these.
Curently, neither Android 3.x nor Android 4.0 has a significant market share, but this will change drastically in 2012, and the cycle will begin anew, for better or for worse.
