How to utilize Android Car API inside an app

Question

I want to test and (if possible) utilize Android Car API functionalities inside my Android app. Specifically, I need to be able to import classes under android.car.* package which can be seen here: https://developer.android.com/reference/android/car/packages.html

I also found the repo on Google Git: https://android.googlesource.com/platform/packages/services/Car/

How should I add this library as a dependency in my app?

Answer 1

The library is now released as part of Android Q SDK in Android Studio. You need to

1. update the SDK 29 to minor version 5 using SDK manager

2. Update app module build.gradle include car-lib

    android { compileSdkVersion 29 buildToolsVersion "29.0.3" ... useLibrary 'android.car' }

3. API documentation is available here

Answer 2

There's no prebuilt binary for android.car , but you can build it yourself by running mm in packages/services/Car/car-lib : https://android.googlesource.com/platform/packages/services/Car/+/refs/heads/master/car-lib/Android.bp#50

If your app has an .mk or .bp file, you can include the library like CarService does here: https://android.googlesource.com/platform/packages/services/Car/+/master/service/Android.mk#42

The library is mostly meant for OEMs though and not so much for third parties.

For Linux you need to first set the environment and then build it:

. build/envsetup.sh

lunch aosp_car_x86-userdebug

make -j8
