How do I install an apk in Waydroid, if running in Cage

There must be something different when running under Cage

  users.extraUsers.waydroid.isNormalUser = true;
  services.cage.user = "waydroid";

As the waydroid user, I try:

$ waydroid app install hukarz.apk
[15:51:01] WayDroid session is stopped

I assume it’s the waydroid user I should run this as?

ok, this is strange

[waydroid@surface2pro:~]$ ls -ld .local/share/waydroid/data/
drwxrwx--x 51 b0ef 1000 4096 okt.  26 21:43 .local/share/waydroid/data/

That directory pops up as another user account I have, but why?

I know I ran Waydroid under that account before…

I ran the init under that user, but Waydroid is starting up just fine.

I’m a bit confused here.
