I have developed media applications like music player, navigation, weather and podcast in android studio using PIE automotive emulator(API 28) which is working in this emulator now I have to flash it on the Intel hardware to do that I want an OS which have to be downloaded and built, I had choose the target aosp_car_x86-userdebug but here the boot.img is missing, or which android version I can choose to build the source code, how to proceed with this problem.
