        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadDataWithBaseURL("", html, "text/html", "UTF-8", "");
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setDomStorageEnabled(true);
        webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

        webView.addJavascriptInterface(new PaymentSucess(this), "Payment");

        webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);

                //  webView.loadUrl(myResult);


            }
