WebViewOutcomeReceiver

public interface WebViewOutcomeReceiver<T, E extends Throwable>

Known direct subclasses
OutcomeReceiverCompat

This interface is deprecated.

The OutcomeReceiverCompat name clashes with the same class in androidx.core, so the webkit library version was renamed to avoid confusion.

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.

This interface serves the same purpose as android.os.OutcomeReceiver, but can be used on API versions before 31. It is also identical to androidx.core.os.OutcomeReceiverCompat, but the androidx.webkit library maintains a separate copy to be able to remain at compileSdk = 33, which would not be possible with a dependency on androidx.core:core:1.16.0, which uses compileSdk = 35.

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.

Summary

Public methods
