Android for Cars overview

Bring your app to vehicles running either Android Auto or Android Automotive OS. Use one app architecture that works for both cases so every user can enjoy your app.

Android Auto

Android Auto provides a driver-optimized app experience for users with an Android phone and the Android Auto app, but who do not have a vehicle that uses Android Automotive OS. If a user's car or aftermarket stereo system supports Android Auto, they can use your app directly on their car's display by connecting their phone.

You enable Android Auto to connect with your phone app by creating services that Android Auto uses to display a driver-optimized interface to the driver. You reuse these services for your Android Automotive OS app, but users do not install your phone app on their cars.

Android Auto already has millions of users and hundreds of compatible cars and aftermarket stereo systems.

Android Automotive OS

Android Automotive OS is an Android-based infotainment system that is built into vehicles. The car's system is a stand-alone Android device that is optimized for driving. With Android Automotive OS, users install your media app directly onto the car’s system instead of their phones.

Your app must include a media browser service (see Build media apps for cars for instructions). You can use the same media browser service with both Android Automotive OS and Android Auto. However, there are some activities such as sign-in and settings that you must design specifically for Android Automotive OS. For more information, see Adapt sign-in flow and Design settings in the Android Automotive OS app design guidelines.

Supported app categories

Android Auto and Android Automotive OS support the following types of apps:

Media apps
Media apps let users browse and play music, radio, audiobooks, and other audio content in the car. You can build, test, and distribute media apps on Android Auto. You can also build, test, and distribute media apps for Android Automotive OS. See Build media apps for cars for more information.
Messaging apps
Messaging apps let users receive incoming notifications, read messages aloud using text-to-speech, and send replies via voice input in the car. You can build, test, and distribute messaging apps on Android Auto. See Build messaging apps for Android Auto for more information.
Navigation, parking, and charging apps
Navigation, parking, and charging apps help users get where they want to go, find a place to park, or locate the nearest charging station. To develop these types of apps, you use the Android for Cars App Library. See Using the Android for Cars App Library for more information.
