Question: If I want to use compose in an existing view based application, is that possible? Googling shows mention of a GenerateView annotation, but apparently that was an old concept. Is there some new preferred Compose way of doing this? (I would like to be able to have a Compose function fill a view and still keep using views elsewhere in my app)

You can add Compose to an Activity or to a ViewGroup (https://developer.android.com/reference/kotlin/androidx/ui/core/package-summary#(android.view.ViewGroup).setContent(kotlin.Function0))

oh great! I can add it to a ViewGroup. Brilliant! thanks
