<p>For your app to use certain emulator device features, you need to specify

in the manifest that your app will use them. For example, an Android Wear watch

requires the following <code>&lt;uses-feature&gt;</code> setting:</p>

<pre>

<uses-feature android:name="android.hardware.type.watch" />

</pre>

<p>There are also settings for camera, location, audio, microphone, phone,

networking, TV, touchscreen, and more. For more information, see

&lt;uses-feature&gt;</a>.</p>
