ActivityResultRegistry

Kotlin |Java

abstract class ActivityResultRegistry

kotlin.Any
↳	androidx.activity.result.ActivityResultRegistry

A registry that stores activity result callbacks for ActivityResultCaller#registerForActivityResult. You can create your own instance for testing by overriding onLaunch and calling #dispatchResult immediately within it, thus skipping the actual Activity#startActivityForResult call. When testing, make sure to explicitly provide a registry instance whenever calling ActivityResultCaller#registerForActivityResult, to be able to inject a test instance.
