Nope, it's downloaded as part of the =waydroid init= command.

You can see the RTE here:
$ ls /var/lib/waydroid/images/
system.img  vendor.img

On waydroid website [1] they provide instructions on how to create this runtime environment - basically "+-" Android rootfs.

I cameacross a channel [2] with Android support but haven't had the chance to test it yet. Then again I'm not sure if that's the right way as there are phones that run close to vanilla Linux [3]. Though this technological solution enables Android apps to run on those phones.

But it also has drawback as it requires custom kernel.

Though these patches require support in the kernel [3] and LXD service running [4] at least.

Currently I'm able to run the waydroid container and get shell over adb.

However, for some unknown reason I can't launch the UI.

That might be due to the fact I run Sway VM. I'll test this with GDM as this is recommended in the issues on github and report back.
