Froyo is Now on 61.3% of All Android Devices
Fragmentation remains an issue on Android, but as the platform matures, it seems to be less and less an issue. Case in point: As of March 15th, Froyo (Android 2.2) is the dominant version of Android, having a presence on 61.3% of Android devices.
What does this mean? For the average customer, it probably doesn't mean much, but for developers, it means greater confidence in writing apps with Froyo-specific features, as now the majority of your potential customers will be able access it. What's more, devices (phones and tablets) supporting Android 2.1 and higher is now 90.3%.
While these adoption rates are promising, they're still really slow, as Gingerbread (2.3), is only present on 0.7% devices, which serves to highlight a weakness in the fact that Android devices don't have to be updated by their manufacturers, and that customizations of the OS are allowed, and the norm. They slow things down.
