How to handle errors inside webview?

Question

I want to load a webpage.

private class MyJavaScriptInterface {

    private MyJavaScriptInterface () {
    }

    public void setHtml(String contentHtml) {

        if (contentHtml != null && contentHtml.trim().length() > 0) {
            //Do something
        }
    }
}
private WebViewClient webViewClient = new WebViewClient() {

    @Override
    public void onPageFinished(WebView view, String url) {

        view.loadUrl("javascript:window.ResponseChecker.setHtml"
            + "(document.body.innerHTML);");
        if (progressDialog != null && progressDialog.isShowing()) {
            progressDialog.dismiss();
        }
    }

    public void onReceivedSslError(WebView view, SslErrorHandler handler,
        SslError error) {
        handler.proceed();
    }

    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        Log.e("ProcessPayment", "onReceivedError = " + errorCode);
    }

};

I want to handle webpage loading errors. I know that the errors can be obtained in onReceivedError(...) method.

My problem is how can I handle the error without showing Page Not found in webview? (eg: Show a dialog and makes webview blank).

Thanks in Advance.

Check as:

 public void onReceivedError(WebView view, int errorCode, 
                           String description, String failingUrl) {
             Log.e("ProcessPayment", "onReceivedError = " + errorCode);

            //404 : error code for Page Not found
             if(errorCode==404){
               // show Alert here for Page Not found
               view.loadUrl("file:///android_asset/Page_Not_found.html");
             }
            else{

              }
           }
