如何在Android应用程序中集成TEST PayU Payment Gateway？

  我认为你的代码没问题，我也是这样做的，并且从payu那里了解到 test merchant_key 和 salt 目前无效 . 尝试 生产环境 模式 .

  如果要从服务器使用（postUrl）加载数据：

  post_Data = "hash="+PayMentGateWay.this.hash+"&key="+merchant_key+"&txnid="+PayMentGateWay.this.params.get("txnid")+"&amount="+PayMentGateWay.this.params.get("amount")+
                  "&productinfo="+PayMentGateWay.this.params.get("productinfo")+"&firstname="+PayMentGateWay.this.params.get("firstname")+
                  "&email="+PayMentGateWay.this.params.get("email")+"&phone="+PayMentGateWay.this.params.get("phone")+
                  "&surl="+PayMentGateWay.this.params.get("surl")+"&furl="+ PayMentGateWay.this.params.get("furl")+
                  "&service_provider="+ "payu_paisa";
  
   webView.postUrl("https://secure.payu.in/_payment", EncodingUtils.getBytes(post_Data, "base64"));
  

  我希望这有帮助 .

  Hey guys I have successfully implemented payment Gateway

  在drawable for progress对话框中使用的图像

  

  

  

  

  PayUMoneyActivity

  public class PayUMoneyActivity extends AppCompatActivity {
  
  WebView webView;
  Context activity;
  /**
   * Order Id
   * To Request for Updating Payment Status if Payment Successfully Done
   */
  int mId;

  private String mSalt = "GQs7yium";//copy and paste works fine 
  private String mBaseURL = "https://test.payu.in";
  private String mAction = ""; // For Final URL
  private String mTXNId; // This will create below randomly

  “抱歉，发生了一些问题”当您没有有效的商家密钥和Salt密钥时，会出现此错误 . 在这种情况下，您需要联系PayU Money客户服务支持团队获取有效的Merchant和Salt密钥 . 希望这会帮助你 .

  我遇到了同样的问题，并且厌倦了这种集成 .

  但在与payumoney.com运动团队联系后，他们告诉我下载套件中显示的集成套件未激活，这是关键（JBZaLc）和盐（GQs7yium），它只是一个虚拟数据 . 因此，我们需要发送您的公司详细信息，包括银行详细信息，然后他们验证您的公司详细信息，然后他们将为我们提供新的集成套件 . 使用该套件，我们可以进行测试 .
