Review the following information to learn how make changes to your app's manifest so that Android Auto can discover and interact with your app's`CarAppService`.

## Declare Android Auto support

The[Android Auto host](https://developer.android.com/training/cars/apps#key-terms-concepts)checks whether the app has declared support for[Android Auto](https://developer.android.com/training/cars#auto). To enable this support, include the following entry in your app's manifest:  

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

This manifest entry refers to another XML file that you create with the path<var translate="no">AppProjectDirectory</var>`/app/src/main/res/xml/automotive_app_desc.xml`. In that file, you declare what Android Auto capabilities your app supports.

Apps using the[Android for Cars App Library](https://developer.android.com/reference/androidx/car/app/package-summary)must declare the`template`capability in the`automotive_app_desc.xml`file:  

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