Android TV onReceivedError测试

Question

I use a web view in my Android TV app and have handlers attached to it like:

        webView.setWebViewClient(new WebViewClient() {
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            Toast.makeText(context, "Oh no! " + description, Toast.LENGTH_SHORT).show();
            webView.loadUrl("file:///android_asset/error.html");
        }
    });

How would I go about testing this?

onReceivedError:

This method was deprecated in API level 23.

you should to use

void onReceivedError (WebView view, 
                WebResourceRequest request, 
                WebResourceError error)

onReceivedError in android docs

If you want to test the error case, try to connect a unknown web page, for example: http://google.com/404

run this code after creating and initializing the webview object

webView.loadUrl("http://google.com/404");

I hope this code will trigger the onReceivedError function
