At the beginning of every month, Google gives us a glimpse of the status of Android versions distributed across the market. For developers, it's a useful metric of which versions, as well as which device and display sizes, are dominating the market. For users and industry observers, it gives some insight into the trends and, sadly, the fragmentation of the Android platform. For the month of December, we're glad to see Android 6.0 Marshmallow step up a bit from, 0.3 to 0.5 percent, in just a month's time. But we're also perplexed that one of the oldest versions of Android, 2.2 Froyo, still manages to stick around month after month.
