would it be possible, to start activity for result (e.g. select file), if you only have context. I have a wild idea of making interactor/usecase that does that. Any ideas?

class SelectFileUseCase @Inject constructor(
    @ApplicationContext private val context: Context
) {
    operator fun invoke(): Uri {
        val intent = Intent().apply {
            type = "file/*"
            action = Intent.ACTION_GET_CONTENT
            addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        }

        context.startActivity(intent)
        
        // how to get result??
        context.registerReceiver(receiver, filter) // maybe?
    }
}

Nope, an activity started for result needs an activity to return the result to

bummer. Thanks!

That being said, you absolutely can push all of the intent handling out into your own, separately testable class if you're using the ActivityResultRegistry class and its methods: https://developer.android.com/training/basics/intents/result#separate

(you just need to hook it up to an activity / its ActivityResultRegistry at some point)
