Components are the building blocks for the visual design of the Android Automotive OS (AAOS) interface. Some AAOS components and their customizable properties are implemented in the car UI library, while others are standard AOSP components, or need to be built from scratch following the specs provided here.

This section describes the anatomy, visual specs, and styles for AAOS components.
