Should I be using

androix

packages if I'm starting a new app?

This has nothing to do with Kotlin.... But I would.

Well, a lot of the Kotlin extensions are only available to

androidx

, as far as I can tell, so I thought it was related enough

We did this, no regrets

@gildor You mean you are using the 1.0.0-beta1 support libraries?

@Paul Woitaschek Yes, correct. We target API level 28 and use 1.0.0-beta1 for most of androidx libraries
