> If I understand correctly, onReceivedError handles WebView loading errors, both for a document loaded into a WebView and for iframes loaded inside the document. Currently onReceivedError has actually to outcomes: load page specified via errorUrl property into WebView or show error dialog and close activity.
> Both outcomes are not desired when error came from loading iframe since application loaded into the WebView loses control of all events and can not handle iframe loading error.
> I think it would be more appropriate to check failingUrl and if it does not equals to this.url - just do not catch error in onReceivedError, thus allowing scripts from document loaded into WebView handle iframe loading errors.
