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.

You must use a kernel with the android-specific modules compiled in, or use the
binder_linux-dkmsmodule. I’ve noticed using a kernel with them built in is generally easier to get working.
