我完成了:) :)你必须编辑 SuccessURL 和 FailureURL ：

它完美地为我工作 .

public class PayUMoneyActivity extends AppCompatActivity {

    WebView webView;

Build Custom Integration

根据payumoney：如果您从头开始构建您的网站，您需要向我们的API发布请求 . 传递您的密钥和其他强制变量 . 这还包括成功和失败页面URL，您希望在该URL中了解用户的成功和失败案例 . 第1步：与我们的任何电子商务平台合作伙伴一起创建商店 . 第2步：选择PayUMoney作为付款选项 . 第3步：输入PayUMoney凭证，您就可以开始了 .

Note: 您需要开发自己的Web服务，从客户端应用程序获取数据并将请求转发给payumoney服务器，然后在您的Web服务通知您结果之后接收回调响应 .

FlipKart，FreeCharge，Snapdeal等他们有自己的网址，负责启动支付网关，

因此，您需要从服务器团队获得支持以启动付款并将结果返回给客户端应用程序 .

你可以找到更多关于payumoney和api payumoney integration的信息，
