OutcomeReceiverCompat

@Profile.ExperimentalUrlPrefetch
public interface OutcomeReceiverCompat<T, E extends Throwable>

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
<T>

The type of the result that's being sent.
<E extends Throwable>

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. TODO(b/380060342): To be removed once we release androidx.core.os.OutcomeReceiverCompat.
