成功したURLがwebviewにロードされたときのコールクラスまたはアクティビティ

Question

私は成功したPayUMoney Payment Gateway in My Appです。私は成功裏に支払が完了した場合、1つのクラスまたはアクティビティを呼びたいと思います。支払いが失敗した場合このクラスまたはアクティビティは呼び出しません。私はたくさんのことをしようとしていたが、私のために働くものは何もない。

      webviewPayment.setWebViewClient(new WebViewClient() { 
       @Override 
       public void onPageStarted(WebView view, String url, Bitmap favicon)

        dialog.show(); 
       } 
       @Override

        super.onPageFinished(webviewPayment, url); 
        if (dialog.isShowing()) 
         dialog.dismiss();

たぶん私は誤解していますが、単に

mContext.startActivity(new Intent(mContext, YourActivity.class);
