Question

我正在Android应用程序中实现PayUmoney付款网关集成。

当我在应用程序中运行付款方式时，出现以下错误消息。

 Some error occurred

还有以下例外情况

    java.lang.RuntimeException:
    Unable to start activity 
    ComponentInfo{com.XXX.XXX/com.payumoney.sdkui.
    ui.activities.PayUmoneyActivity}:
    java.lang.NullPointerException: 
    Attempt to invoke virtual method 'void 
    com.payumoney.core.PayUmoneySDK.addPayment
    (com.payumoney.core.listener.OnPaymentOptionReceivedListener, 
    java.lang.String)' 
    on a null object reference

下面是我尝试过的一些链接

以下是付款代码

   private void makePayment() {
           //Creating Transaction Id
           Random rand = new Random();
           String randomString = Integer.toString(rand.nextInt()) + 
           (System.currentTimeMillis() / 1000L);
           mTXNId = hashCal("SHA-256", randomString).substring(0, 20);



    double roundOffAmount = Math.round(payamount * 100.0) / 100.0;

    String productName = "Test";

    String udf1 = "";
    String udf2 = "";

    mHash = hashCal("SHA-512",

    /**

    mAction = mBaseURL.concat("/_payment");

    PayUmoneySdkInitializer.PaymentParam.Builder builder = new
            PayUmoneySdkInitializer.PaymentParam.Builder();
    builder.setAmount(String.valueOf(roundOffAmount)) // Payment amount
            .setTxnId(mTXNId) // Transaction ID
            .setPhone("9874563210") // User Phone number
            .setProductName(productName) // Product Name or description
            .setFirstName(userName) // User First name
            .setEmail(userEmail) // User Email ID
            .setsUrl(mSuccessUrl) // Success URL (surl)
            .setfUrl(mFailedUrl) //Failure URL (furl)
            .setUdf1(udf1)
            .setUdf2(udf2)
            .setUdf3(udf3)
            .setUdf4(udf4)

            .setIsDebug(false) // Integration environment - true (Debug)/ 
                                false(Production)
            .setKey(mMerchantKey) // Merchant key
            .setMerchantId(mMerchantId);

    //declare paymentParam object
    PayUmoneySdkInitializer.PaymentParam paymentParam = null;
    try {
        paymentParam = builder.build();
    } catch (Exception e) {
        e.printStackTrace();
    }

 //set the hash
   paymentParam.setMerchantHash(mHash);


    // Invoke the following function to open the checkout page.
     PayUmoneyFlowManager.startPayUMoneyFlow(paymentParam, 
     PaymentMethodAddressActivity.this, R.style.PaymentAppTheme, true);
}

我不知道我的代码有什么问题。

请帮助我解决此问题。

Answer 1

我替换了这一行

 builder.setAmount(String.valueOf(roundOffAmount))

与

 builder.setAmount(roundOffAmount)

现在一切都按我的预期工作正常。
