(warning dumb question incoming): since android apps are java, is it possible for a third contender to create a jvm for their platform and some hooks for android api’s and run anything that was made for them?
I completely forgot about waydroid due to Wayland not being ready for general use.
(Aside from accessibility stuff mentioned on hn numerous times, still doesn't allow keepass to type passwords last I checked. Admittedly, I check Wayland about as often as I check Hurd.)
