New data on the state of the Android ecosystem has been posted toÂ Googleâ€™s Android Developers site. The big reveal?Â Gingerbread, the version of the Android mobile operating system released back in December 2010, is stillÂ leading with 57.5% of Android OS share. Android 4.0 (Ice Cream Sandwich) is at 20.9%, and Android 2.2 (Froyo) has 14%. Yes, Froyo â€“ released in May 2010. And as for the newest version of Android, akaÂ Jelly BeanÂ (Android 4.1)? Itâ€™s now installed on 1.2% of Android devices, up from 0.8% a monthÂ ago.
The following stacked line graph provides a history of the relative number of active Android devices running different versions of the Android platform. It also provides a valuable perspective of how many devices your application is compatible with, based on the platform version.
Notice that the platform versions are stacked on top of each other with the oldest active version at the top. This format indicates the total percent of active devices that are compatible with a given version of Android. For example, if you develop your application for the version that is at the very top of the chart, then your application is compatible with 100% of active devices (and all future versions), because all Android APIs are forward compatible. Or, if you develop your application for a version lower on the chart, then it is currently compatible with the percentage of devices indicated on the y-axis, where the line for that version meets the y-axis on the right.
Each dataset in the timeline is based on the number of Android devices that accessed Google Play within a 14-day period ending on the date indicated on the x-axis.
Last historical dataset collected during a 14-day period ending on September 1, 2012
Screen Sizes and Densities
This section provides data about the relative number of active devices that have a particular screen configuration, defined by a combination of screen size and density. To simplify the way that you design your user interfaces for different screen configurations, Android divides the range of actual screen sizes and densities into:
- A set of four generalizedÂ sizes:Â small,Â normal,Â large, andÂ xlarge
- A set of four generalizedÂ densities:Â ldpiÂ (low),Â mdpi(medium),Â hdpiÂ (high), andÂ xhdpiÂ (extra high)
