How to pass data from webview back to the native Android app

Question

Our Android app has a WebView which shows a page from our web-server. The page does a user registration (either via Facebook or by choosing a username and password). After that, I want the page to pass information back to the native app (e.g., username, license type, messges, etc.).

After the user logs in, you can capture data from the URL using WebView::getUrl(). Alternately, you could use cookies.
