Is there an example on how to use the new Activity Results API with Compose? I'd like to do a Google sign-in from a Composable and would rather not pass down something from the Activity all the way down to the Composable

Did you try to get the current context, cast it to activity and registerForActivityResult on that one?

[galex]

Not yet, will try

[Joost Klitsie]

This is highly untested and possibly wrong, but a step in that direction:

(ContextAmbient.current as? Activity)?.registerForActivityResult(PostActivityContract()) { result ->
            // parseResult will return this as string?                                              
            if (result != null) toast("Result : $result")
            else toast("No Result")
        }?.launch()

(ContextAmbient.current as? ComponentActivity)

And it works! Nice 🙂

Now I need to build the Contract for Google Sign-in! Thanks @Joost Klitsie

I would say to be careful with ContextWrappers. You will have to find the activity instead of just casting

[Joost Klitsie]

@Ricardo C. Which context could it be otherwise? With the old views the context was always the activity, do you think it could be something different now?

[Ricardo C.]

It can be a ContextWrapper, I believe

[Joost Klitsie]

Ah yeah. In that case a small search wouldn't be bad :)
