<h2 id="Platform">Platform Versions</h2>
<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, read about <a
href="{@docRoot}guide/topics/manifest/uses-sdk-element.html#ApiLevels">API levels</a>.</p>
<h3 id="PlatformCurrent">Current Distribution</h3>
<p>The following pie chart and table is based on the number of Android devices that have accessed
Google Play within a 14-day period ending on the data collection date noted below.</p>

<h3 id="PlatformHistorical">Historical Distribution</h3>
<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
Google Play within a 14-day period ending on the date indicated on the x-axis.</p>

<h2 id="Screens">Screen Sizes and Densities</h2>
<p>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:</p>
<ul>
<li>A set of four generalized <strong>sizes</strong>: <em>small</em>, <em>normal</em>,
<em>large</em>, and <em>xlarge</em></em></li>
<li>A set of four generalized <strong>densities</strong>: <em>ldpi</em> (low), <em>mdpi</em>
(medium), <em>hdpi</em> (high), and <em>xhdpi</em> (extra high)</li>
</ul>
<p>For information about how you can support multiple screen configurations in your
application, see <a href="{@docRoot}guide/practices/screens_support.html">Supporting Multiple
Screens</a>.</p>

of Android devices that have accessed Google Play within a 7-day period
ending on the data collection date noted below.</p>

<h2 id="OpenGL">Open GL Version</h2>
<p>This section provides data about the relative number of active devices that support a particular
version of OpenGL ES. Note that support for one particular version of OpenGL ES also implies
support for any lower version (for example, support for version 2.0 also implies support for
1.1).</p>
<p>To declare which version of OpenGL ES your application requires, you should use the {@code
android:glEsVersion} attribute of the <a
href="{@docRoot}guide/topics/manifest/uses-feature-element.html">{@code &lt;uses-feature&gt;}</a>
element. You can also use the <a
href="{@docRoot}guide/topics/manifest/supports-gl-texture-element.html">{@code
&lt;supports-gl-texture&gt;}</a> element to declare the GL compression formats that your application
uses.</p>

of Android devices that have accessed Google Play within a 7-day period
ending on the data collection date noted below.</p>
