How to check if webview failed to load page (android)?

Question

I have a webview in my app, however sometimes due to connectivity the webview fails to load and I get the default webpage unavailable page. I want to show an alertdialog if the webview failed to load. Is there anyway I can check (maybe in the shouldOverridePageLoad function) that a webview loaded successfully? Thanks again

Answer 1

Use a WebClient on your web view as follow :

webView.setWebViewClient(new WebViewClient(){  @Override public void onReceivedError(WebView view, WebResourceRequest request,       WebResourceError error) {     super.onReceivedError(view, request, error);     // Do something   } }); 

Answer 2

Extending on Damien's answer on using WebViewClient, there are four listeners available on WebViewClient to check for the success and failure of loading web pages.

webView.setWebViewClient(new WebViewClient() {     @Override     public void onPageFinished(WebView view, String url) {     }      @Override     public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {     }      @Override     public void onReceivedHttpError(             WebView view, WebResourceRequest request, WebResourceResponse errorResponse) {     }      @Override     public void onReceivedSslError(WebView view, SslErrorHandler handler,                                    SslError error) {     } }); 

There is also:

@Override public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {    } }); 

which is deprecated in favor of its overload mentioned in the above code.
