The ability to run android apps has now been introduced on Insider versions and works on release version, although it is not official as far as I know.
However it is limited to a number of countries, and only works with a limited range Apps from the Amazon Appstore.
MS missed the biggest opportunity here by not collaborating with Google Playstore. Politics of course.
Regarding Android emulators, most of them are effectively type 2 hypervisors and will have issues if Hyper-V or Windows Hypervisor Platform is installed. Latter is used by Defender Credential Guard (if Hyper-V is not installed)
These would have to use Windows Hypervisor Platform APIs and should coexist. However performance will take a hit.
There is a workaround by disabling the hyperV hypervisor, using bcdedit but you may also need to disable Defender Credential Guard as well (not tested so cannot say for sure).
The new android tool works ok with hyper-v etc installed, as it uses a different method of execution via Windows Subsystem For Android which is similar to the Windows System For Linux.
EDIT: See post
