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.
A lot of android apps are built using Java/Kotlin, so you don’t actually need to care about architecture since the JVM supports both x86_64 and arm64.
There are exceptions to this though, since some apps need to run native code. Those apps would need some sort of emulation/translation layer for the arm instructions.
