我正在我的android应用程序中实现CCAvenue支付网关，但当我重定向到webviewactivity（CCAvenue的支付页面）时，它会显示空白屏幕。我不确定我做错了什么。所以我在这里发布我的webviewactivty代码和logcat。请调查一下

WebViewActivity：

            final WebView webview = (WebView) findViewById(R.id.webview);

                    Toast.makeText(getApplicationContext(), "Oh no! " + description, Toast.LENGTH_SHORT).show();
                }
            });

            /* An instance of this class will be registered as a JavaScript interface */
            StringBuffer params = new StringBuffer();
            params.append(ServiceUtility.addToPostParams(AvenuesParams.ACCESS_CODE,mainIntent.getStringExtra(AvenuesParams.ACCESS_CODE)));

            params.append(ServiceUtility.addToPostParams(AvenuesParams.ORDER_ID,mainIntent.getStringExtra(AvenuesParams.ORDER_ID)));

            params.append(ServiceUtility.addToPostParams(AvenuesParams.CANCEL_URL,mainIntent.getStringExtra(AvenuesParams.CANCEL_URL)));
            params.append(ServiceUtility.addToPostParams(AvenuesParams.ENC_VAL, encVal));

            String vPostParams = params.substring(0, params.length() - 1);

            try {
                String postData = URLEncoder.encode(vPostParams, "UTF-8");
                webview.postUrl(Constants.TRANS_URL, postData.getBytes());
            } catch (Exception e) {
                showToast("Exception occured while opening webview.");
            }
        }
    }

    public void showToast(String msg) {
        Toast.makeText(this, "Toast: " + msg, Toast.LENGTH_LONG).show();
    }
}

而不是这个代码 params.append（ServiceUtility.addToposParams（AvenuesParams.ENC_VAL，encVal））
试试这个代码
ENC_VAL，URLEncoder.Encode（encVal）
通常，对于CCavenueTransation，您应该将所需参数附加到CCAvenueTransaction url

在webview中。在此之前，您应该对加密数据进行编码，因为它可能包含问号（？）、符号（&）、斜杠（/）和空格等字符。它可能被webview或浏览器截断或损坏。因此，CCAVENCE服务器无法理解您的参数
