| <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> |
