According to the android documentation, onReceivedError() should be able http://stackoverflow.com/questions/4997677/android-webview-onreceivederror to intercept. but i tested it in an app which I deleberately gave the wrong URL, and it didn't do anything. I want my app to be able to give my own custom error message if the URL is ever unavailable for any reason. this is the code that did nothing: public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { // custom error handling ... show and alert or toast or something } android webview share|improve this question edited Sep 26 '11 at 9:55 Octavian Damiean 30.3k178091 asked Feb 14 '11 at 21:49 Joe Winfield 2513714 add a comment| 3 Answers 3 active oldest votes up vote 26 down vote According to documentation and my experience it should work quite fine. You just have to set your WebClient with overriden method onReceivedError in your WebView. Here is the snippet from some of my old test app: WebView wv = (WebView) findViewById(R.id.webView); wv.setWebViewClient(new WebViewClient() { @Override public void onReceivedError(WebView view, int errorCode, String descriptio

Unanswered How best to implement error handling and timeout on WebView when loading a page? JohnHardman John HardmanGBUniversity ✭✭✭✭✭ May 2015 in Xamarin.Forms I make use of WebView within my app. It seems to be a bit short on error handling and timeout handling, which occasionally results in, well... nothing - just a blank view. How android webview can I: (1) get a status from the WebView telling me whether it is still loading the DOM, has loaded the DOM and rendered the view, has got an error (and what the error is) etc? (2) get notified when the status in (1) changes (3) specify a timeout on a WebView? (if I can identify whether it has been populated using (1) I can probably workaround this using a timer) And, android webview javascript just in case I need it in future: (4) access the DOM? Many thanks, John H. Tagged: xamarin.forms webview timeout error handling DOM 0 Best Answer hvaughan hines vaughan USMember ✭✭ October 2015 edited October 2015 Answer ✓ @JohnHardman For sure. For iOS, you would create a custom renderer and inherit from WebViewRenderer. Then within that, you would assign a custom WebView Delegate to the custom renderer's Delegate property. Then you can override LoadFailed() from with your custom WebView Delegate like so: public class CustomWebViewRenderer : WebViewRenderer { protected override void OnElementChanged(VisualElementChangedEventArgs e) { base.OnElementChanged(e); if(e.OldElement == null) { Delegate = new CustomWebViewDelegate(); } } } internal class CustomWebViewDelegate : UIWebViewDelegate { #region Event Handlers public override bool ShouldStartLoad(UIWebView webView, NSUrlRequest request, UIWebViewNavigationType navigationType) { //Could add stuff here to redirect the user before the page loads, if you wanted to redirect the user you would do the redirection and then return false return true; } public override void LoadFailed(UIWebView webView, NSError error) { Console.WriteLine("\nIn AppName.iOS.CustomWebViewRenderer - Error: {0}\n", error.ToString()); //TODO: Do something more useful here //Here, you can test to see what kind of error you are getting and act accordingly, either by showing an alert or rendering your own custom error page using basic HTML } public override void LoadingFinished(UIWe
