How to build AOSP for Android Automotive OS?

问题

I have downloaded AOSP codebase for x86 from https://www.android-x86.org/. It builds fine. I wonder how I setup the config or .mk, so that I can compile or build Android with Android Automotive OS flavor.

Any pointers?

Refer to /device/generic/car/ repository where AOSP car emulator configuration is available.

The following target variants are available:

aosp_car_arm-userdebug
aosp_car_arm64-userdebug
aosp_car_x86-userdebug
aosp_car_x86_64-userdebug

I recommend to follow the official documentation for downloading and building AOSP: Set up for Android Development. You can choose car emulator as your build target.

In short:

Download some Android repository. In case of Android 10, this could be e.g.:

$ repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r14
$ repo sync

Setup an environment and choose the car emulator target variant that matches your CPU architecture, e.g.
```
$ . build/envsetup.sh
$ lunch aosp_car_x86-userdebug
```
Build the target:
```
$ make
```
After successful build, run the emulator from command line:
```
$ emulator
```
Note: Usually, for development purposes you would like to run the emulator with some additional options, e.g. -selinux permissive (SELinux not enforced) or -writable-system (writable system image). Refer to Start the emulator from the command line documentation for more details.
