<p>This page provides data about the relative number of active devices
|
|
running a given version of the Android platform. This can help you
|
|
understand the landscape of device distribution and decide how to prioritize
|
|
the development of your application features for the devices currently in
|
|
the hands of users. For information about how to target your application to devices based on
|
|
platform version, see <a href="{@docRoot}guide/appendix/api-levels.html">API Levels</a>.</p>

|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>Each dataset in the timeline is based on the number of Android devices that accessed
|
|
Android Market within a 14-day period ending on the date indicated on the x-axis.</p>
