I am currently testing by installing AOSP for AAOS and AOSP Automotive App Host on pixel5 phone.
As the AOSP Automotive App Host source is not updated, only car api level 4 or lower features are supported, so I cannot test car api level 5 or higher features on pixel5 phone.
In the case of the AAOS emulator, I can test up to level 6 features by installing the latest version of Google Automotive App Host through the google play store.
Is there any way to install the latest App Host on AOSP for Android Automotive OS?
