Impl

abstract class Impl<I, O>(val resultRegistry: ActivityResultRegistry, val resultContract: ActivityResultContract<I, O>) : ActivityCallContractHandler<I, O>

Base implementation that registers resultContract during onCreate.

This lets subclasses provide only the registry key/callback behavior they need instead of repeating launcher registration code.

Constructors

constructor(resultRegistry: ActivityResultRegistry, resultContract: ActivityResultContract<I, O>)

constructor(activity: ComponentActivity, activityResultContract: ActivityResultContract<I, O>)

Enable construction from activity

Properties

open override val registryKey: String

Key by which resultCallback will be identified within resultRegistry

abstract val resultCallback: (O) -> Unit

Callback invoked with the contract output.

open override val resultContract: ActivityResultContract<I, O>

Contract that converts inputs and outputs for the activity call.

open lateinit override var resultLauncher: ActivityResultLauncher<I>

Launcher created during lifecycle registration.

open override val resultRegistry: ActivityResultRegistry

Registry used to create the launcher.
