TwitterOAuthView

Overview

A WebView subclass dedicated to Twitter OAuth on Android, using twitter4j.

As this class is implemented as a subclass of View, it can be integrated into the Android layout system seamlessly. This fact makes this class an easily-reusable UI component.

To use this class, it is not necessary to review the flow of OAuth handshake. Just implement TwitterOAuthView.Listener and call start() method. The result of OAuth handshake is reported via either of the listener's methods, onSuccess() or onFailure().
