I used to hate android emulators, since the ones I’d tested on Windows were ad-ridden, slow bloatware.
The other day I needed to run an android app on Fedora 40.
I tried Waydroid and it worked very well. The app ran supersmooth as if it was running natively.
Also the cli syntax was very sane an user friendly.
waydroid app install|run|list …
So if you need an Android app on linux the experience might be better than what you think it would be.
some android kernels are, but AOSP itself can run perfectly happy on a vanilla kernel, just make sure your kernel was compilled with BINDER enabled, which yes, is upstream
