+
+<p>This library provides {@link android.support.v7.media.MediaRouter}, {@link
+android.support.v7.media.MediaRouteProvider}, and related media classes that
+support the <a href="https://developers.google.com/cast/">Google Cast
+developer preview</a>. </p>
+
+<p>In general, the APIs in the v7 mediarouter library provide a means of
+controlling the routing of media channels and streams from the current device to
+external screens, speakers, and other destination devices. The library includes
+APIs for publishing app-specific media route providers, for discovering and
+selecting destination devices, for checking media status, and more. For detailed
+information about the v7 mediarouter library APIs, see the
+{@link android.support.v7.media android.support.v7.media} package in the API
+reference.</p>
+
+<p>The v7 mediarouter library is located in the
+<code><sdk>/extras/android/support/v7/mediarouter/</code> directory after
+you download the Android Support Library. It's provided as a library project
+with a dependency on the v7 appcompat library, so you'll need to include both
+libraries in your build path when setting up your project. For more information
+on how to set up your project, follow the instructions in <a
+href="{@docRoot}tools/support-library/setup.html#libs-with-res">adding libraries
+with resources</a>. If you are developing in Eclipse/ADT, make sure to include
+both the <code>android-support-v7-mediarouter.jar</code> and
+<code>android-support-v7-appcompat.jar</code> files.</p>
+
+<p>If you are using Android Studio, all you need to do is specify the Gradle build
+script dependency identifier <code>com.android.support:support-v7-mediarouter:<revision></code>,
+where "18.0.0" is the minimum revision at which the library is available. For example:</p>
+
+<pre>
+com.android.support:support-v7-mediarouter:18.0.0
+</pre>
+
+<p class="caution">The v7 mediarouter library APIs introduced in Support Library
+r18 are subject to change in later revisions of the Support Library. At this
+time, we recommend using the library only in connection with the <a
+href="https://developers.google.com/cast/">Google Cast
+developer preview</a>. </p>

through the library APIs. Each Support Library is backward-compatible to a specific Android API

<p>Including the Support Libraries in your Android project is considered a best practice for

application, increase performance and broaden the reach of your application to more users.
