CarIcon

public final class CarIcon
extends Object

java.lang.Object
   ↳ androidx.car.app.model.CarIcon

Represents an icon to be used in a car app.

Car icons wrap a backing IconCompat, and add additional attributes optimized for the car such as a CarColor tint.

Car Screen Pixel Densities

Similar to Android devices, car screens cover a wide range of sizes and densities. To ensure that icons and images render well across all car screens, use vector assets whenever possible to avoid scaling issues. If your app relies on bitmaps or other non-vector assets, you should ensure that you have resources that address multiple pixel density buckets using configuration qualifiers in your resource folders (e.g. "mdpi", "hdpi", etc). See CarContext for more details.

Themed Drawables

Vector drawables can contain references to attributes declared in a theme. For example: 
<vector ...
   <path
     android:pathData="..."
     android:fillColor="?myIconColor"/>
 </vector>
The theme must be defined in the app's manifest metadata, by declaring them in a theme and referencing it from the androidx.car.app.theme metadata.

In AndroidManifest.xml, under the application element corresponding to the car app: 

<meta-data
   android:name="androidx.car.app.theme"
   android:resource="@style/CarAppTheme"/>
The CarAppTheme style is defined as any other themes in a resource file: 
<resources>
   <style name="CarAppTheme">
     <item name="myIconColor">@color/my_icon_color</item>
     ...
   </style>
 </resources>
