You need to make a few changes to your app's manifest so that Android Auto can discover and interact with your app's media browser service.
| **Important:** This guide assumes that you have already[built a media browser service](https://developer.android.com/training/cars/media#implement_browser)and you want to add support for Android Auto to your existing project. If you are new to app development for cars, see the[Android for Cars overview page](https://developer.android.com/training/cars).

## Declare media support for Android Auto

Use the following manifest entry to declare that your phone app supports Android Auto:  

    <application>
        ...
        <meta-data android:name="com.google.android.gms.car.application"
            android:resource="@xml/automotive_app_desc"/>
        ...
    </application>

This manifest entry refers to an XML file that declares what automotive capabilities your app supports. To indicate that you have a media app, add an XML file named`automotive_app_desc.xml`to the`res/xml/`directory in your project. This file should include the following content:  

    <automotiveApp>
        <uses name="media"/>
    </automotiveApp>
