@Lucus16 as someone who has never ran anbox before I'm having some issues with it.

When I compile your branch I see anbox, anbox-application-manager and list_cpu_features under the bin directory. The anbox-application-manager is not executable so I tried the anbox executable instead. It launches a window which told me to run this instead: anbox launch --package=org.anbox.appmgr --component=org.anbox.appmgr.AppViewActivity. When I ran that command the window eventually timed out and closed with [daemon.cpp:61@Run] Application manager service is not running yet.

Could you let me know how I can properly test this please?

I believe you need to have some kernel modules loaded. This is just the graphical frontend.
On master there is a module taking care of the system config.

I must admit I didn't check execution in detail, just that the binaries run at all. I wanted to play around with Anbox, but found the build broken, so I fixed that first. I figured if it turns out to be broken at runtime, I could make a separate issue for that, since fixing the build is already an improvement regardless. Should you want to test it in more detail, I believe the module mentioned is the best way. If you'd rather not change your configuration, you can just read through the module to see what steps it takes.

Tested and works fine for me using the nixos module

@GrahamcOfBorg build anbox
