We're starting out with some Android development in our company, and I'm working out which Android versions we should support.
In one of Google's videos from 27th May 2010 (22:34 minutes in) there is a pie chart showing roughly a third of users each for Android 1.5, 1.6 and 2.1.
Does anyone have a more up-to-date source for the percentages of active Android users usingdevices with each version of the platform?
