Can I use

val context = +ambient(ContextAmbient)

from a composable nested within setViewContent{ }?
Currently seem to be getting an NPE because of this.
Is there an alternative way of getting context?

EDIT: Currently I'm doing this from my activity to get context to a listener into my composable function.

val context: Context = this
setViewContent {
        MapApp(context = context)
}

what code is giving you the NPE?

ohhh

[Leland Richardson [G]]

i gotcha

[Leland Richardson [G]]

we should fix this. can you file a bug?

[Leland Richardson [G]]

in the meantime, you can do something like this….

fun Activity.mySetViewContent(content: @Composable () -> Unit) = setViewContent { ContextAmbient.Provider(this, content) }

but you shouldn’t have to do that… we just haven’t provided all of the ambients we should have been in the setViewContent utility function

[Bryan Lee]

sure. and gotcha, i'll do that for now. thanks!
