Android - WebView onReceivedError opposite

Question

How do I know if there were no errors in loading a page in webview? Here is the code for the onReceivedError:

    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
            view.stopLoading();  // may not be needed
            switch (Locale.getDefault().toString()) {
                case "es_ES":
                    view.loadUrl("file:///android_asset/www/errorPage.forRestActivities.es_ES.HTML");
                    break;
                default:
                    view.loadUrl("file:///android_asset/www/errorPage.forRestActivities.en_US.HTML");
                    break;
            }
        }

    });
