Google Android team published a snapshot of the platform which shows the versions of Android most commonly in use. Though the platform is frequently criticized for being highly fragmented, there are three versions used far more than the rest. Out of the six supported versions of Android, it’s a close three-way split between 1.5 (37.2%), 1.6 (29.4%), and 2.1 (32.4%). Version 1.1, 2.0, and 2.0.1 combined only make up 1% of Android users. These numbers aren't an absolute representation of the platform, the Android team puts out this data to help app developers assess the Android landscape and decide which API levels to use when building their apps. There were complaints last week that Twitter neglected the majority of Android users by making its official Android app for 2.0 and up, and this data appears to support the complaints.
