Are the apks compiled in x86?, could this be done in x64 instead? since new Google Android versions do not support x86 anymore...
It’s not x86, compiling Unity for x86 Android is just as non-trivial as ARM64, it’s compiled for 32bit ARMv7. Unity requires switching to a different scripting backend to compile for ARM64/x86/x86_64. New android versions support 32bit ARM, it’s only Google Pixel devices that don’t support running 32bit applications.
