Car Samples Repository

This repository contains a set of individual Android Studio projects to help you get started writing apps for the car.

The samples are categorized by the libraries they use to integrate with the car: - Car App Library - The library that allows developers to build navigation, parking, and charging apps for the Android Auto-compatible cars. The app may be running in a phone connected to the car or in the Android Automotive OS running in the car. - car-lib/ - A sample library for Android Automotive OS.
