Run Android in a VM

Ability to install lates android OS VM and connect it to Mac is a USB device.

Could be used as a real device or a developer that could test an app on it.

 

This could potentially be fulfilled on Apple Silicon Macs if Parallels made its own LineageOS build.

There's an unofficial build of LineageOS that runs on Raspberry Pi 4 really well and you can install the full Google suite (without support).

If Parallels could add support for the kinds of images you use with the Raspberry Pi then it would open up that world to the Mac and make Parallels really special.
