In Android Q, ART is part of the Runtime Module (installed as an APEX).
It's part of the Mainline Modules work in Android.
The libraries you are attempting to add are system libraries. When you add
those dependencies, they'll get pulled into the APEX. These libraries may
not work across Android releases.
ART dependencies on system libraries are now plumbed through libartpalette
(n. palette, small platform-abstraction layer :-) which sits between the
platform and ART.
This is part of enabling ART to update independently from the rest of the
system.
There is still work left to do on the Runtime Module which means that it is
not signed and not updatable in Android Q.
If you really want to put these system libraries in your private ART, you
may be able to just disable the check. Or you can plumb your changes
through the abstraction.
Thanks
