webview.setWebViewClient(new WebViewClient() {

ProgressDialog MyDialog;

      public void onReceivedError(WebView view, int errorCode,String description,String failingUrl) {

Toast.makeText(activity, "Oh no! " + description,
Toast.LENGTH_SHORT).show();
      }
@Override 
public boolean shouldOverrideUrlLoading(WebView view, String url) {   
activity.setProgress(progress * 1000); 
view.loadUrl(url); 
return true; 
 }

    });
