"Your session has been expired. Please re-initiate your transaction. Don't worry... It happens to the best of us." 当我尝试使用Android webview从CC Avenue支付网关使用paytm钱包付款时，会显示错误消息 .

以下是我用于支付网关的代码：

@Override

protected void onCreate(Bundle savedInstanceState) {

progressBarPB = (ProgressBar) findViewById(R.id.progressBarPB);

progressBarPB.setVisibility(View.VISIBLE);

WebView webView = (WebView) findViewById(R.id.paymentGatewayWV);

webView.getSettings().setJavaScriptEnabled(true);

webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

webView.setWebViewClient(new HelloWebViewClient());

webView.clearCache(true);

webView.clearHistory();

clearCookies(this);

webView.loadUrl("payment gateway url");

}

@SuppressWarnings("deprecation")

public static void clearCookies(Context context) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {

CookieManager.getInstance().removeAllCookies(null);

CookieManager.getInstance().flush();

} else {

CookieSyncManager cookieSyncMngr = CookieSyncManager.createInstance(context);

cookieSyncMngr.startSync();

CookieManager cookieManager = CookieManager.getInstance();

cookieManager.removeAllCookie();

cookieManager.removeSessionCookie();

cookieSyncMngr.stopSync();

cookieSyncMngr.sync();

}

}

public class HelloWebViewClient extends WebViewClient {

public HelloWebViewClient() {

// do nothing

}

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);

return true;

}

@Override

public void onPageFinished(WebView view, String url) {

super.onPageFinished(view, url);

progressBarPB.setVisibility(View.GONE);

}

}

有时付款成功完成，如果我再次尝试付款，则显示上述错误 . 我正在清除浏览器中的所有cookie数据，甚至为什么显示这个错误我不明白 . 请帮我一个好的解决方案 . 谢谢 ：) .
