From https://docs.khadas.com/vim2/DownloadAndroidSourceCode.html, it says Android P is only available for VIM1:
For Android Pie (9.0):
$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-vims-pie
Note: Only available for VIM1.
Can VIM2 support Android P and where can I download the AOSP code?
Best regards
