@0n0w1c I spent about a whole day trying to get anbox to run reliably and I think I’ve got it now.
My problem is that I was trying to launch anbox over a tmux session shared over ssh. You need to export the environmental variable and launch anbox from a terminal emulator in your current session. Also make sure that the anbox-container-manager service is enabled.
For me, that looked like:
$ sudo pacman -S anbox anbox-image-aarch64
$ sudo systemctl enable anbox-container-manager
<-- restart -->
$ export EGL_PLATFORM=x11
(at this point, you can try anbox system-info, if you see extensions under egl, anbox should launch)
$ anbox launch --package=org.anbox.appmgr --component=org.anbox.appmgr.AppViewActivity
After about a minute or few, the Anbox Application Manager should launch. If you close it, you can re-lanch from the desktop shortcut in the plasma-mobile launcher.
