Assuming [this](http://developer.android.com/about/dashboards/index.html http://developer.android.com/about/dashboards/index.html) is your source, I'd note that it "is based on the number of Android devices that have accessed Google Play within a 14-day period".
I suspect that it's only loosely correlated to the number of devices in the wild running that version, but very tightly correlated to the users likely to download an app that you write.
- guelo 14y agoSince the Play/Market app periodically checks the servers to look for any app updates it's fair to say that Google's numbers comprise just about all devices running Google Play which is probably 99% of devices. The only notable device without Play is the Kindle Fire which is running Gingerbread 2.3.4
