OutcomeReceiverCompat

interface OutcomeReceiverCompat<R, E : Throwable?>(source)

Callback interface intended for use when an asynchronous operation may result in a failure. This interface may be used in cases where an asynchronous API may complete either with a value or with a Throwable that indicates an error.

Parameters

<R>

The type of the result that's being sent.

<E>

The type of the Throwable that contains more information about the error. This interface serves the same purpose as android.os.OutcomeReceiver, but can be used on API versions before 31.
