In this blog,

I have shown where to add the discount price in PayPal standard payment android SDK.

There is a method called getStuffToBuy to add the item calculating the total amount to pay with PayPal.

And the product items are added like this,

 PayPalItem[] items =
            {
                    new PayPalItem("item #1", 3, new BigDecimal("80.50"), "USD",
                            "sku-12345"),
                    new PayPalItem("item #2", 2, new BigDecimal("10.00"),
                            "USD", "sku-311231"),
                    new PayPalItem("item #3", 1, new BigDecimal("3.99"),
                            "USD", "sku-222111")
            };

PayPalItem[] items =

{

new PayPalItem("item #1", 3, new BigDecimal("80.50"), "USD",

"sku-12345"),

new PayPalItem("item #2", 2, new BigDecimal("10.00"),

"USD", "sku-311231"),

new PayPalItem("item #3", 1, new BigDecimal("3.99"),

"USD", "sku-222111")

};

And if you want to simply add the discount then simply add the discount also like item with the negative price(that will be the discounted price).

PayPalItem[] items =
        {
                new PayPalItem("item #1", 3, new BigDecimal("80.50"), "USD",
                        "sku-12345"),
                new PayPalItem("item #2", 2, new BigDecimal("10.00"),
                        "USD", "sku-311231"),
                new PayPalItem("item #3", 1, new BigDecimal("3.99"),
                        "USD", "sku-222111"),
// add this line for the discount
                new PayPalItem("Discount #4", 5, new BigDecimal("-3.00"),
                        "USD", "sku-000000")
        };

PayPalItem[] items =

{

new PayPalItem("item #1", 3, new BigDecimal("80.50"), "USD",

"sku-12345"),

new PayPalItem("item #2", 2, new BigDecimal("10.00"),

"USD", "sku-311231"),

new PayPalItem("item #3", 1, new BigDecimal("3.99"),

"USD", "sku-222111"),

// add this line for the discount

new PayPalItem("Discount #4", 5, new BigDecimal("-3.00"),

"USD", "sku-000000")

};

So the final code,

private PayPalPayment getStuffToBuy(String paymentIntent) {
    
    PayPalItem[] items =
            {
                    new PayPalItem("item #1", 3, new BigDecimal("80.50"), "USD",
                            "sku-12345"),
                    new PayPalItem("item #2", 2, new BigDecimal("10.00"),
                            "USD", "sku-311231"),
                    new PayPalItem("item #3", 1, new BigDecimal("3.99"),
                            "USD", "sku-222111"),
                    new PayPalItem("Discount #4", 5, new BigDecimal("-3.00"),
                            "USD", "sku-000000")
            };
    BigDecimal subtotal = PayPalItem.getItemTotal(items);
    BigDecimal shipping = new BigDecimal("17.30");
    BigDecimal tax = new BigDecimal("3.47");
    PayPalPaymentDetails paymentDetails = new PayPalPaymentDetails(shipping, subtotal, tax);
    BigDecimal amount = subtotal.add(shipping).add(tax);
    PayPalPayment payment = new PayPalPayment(amount, "USD", "items", paymentIntent);
    payment.items(items).paymentDetails(paymentDetails);

    payment.custom("This is text that will be associated with the payment that the app can use.");

    return payment;
}

private PayPalPayment getStuffToBuy(String paymentIntent) {

PayPalItem[] items =

{

new PayPalItem("item #1", 3, new BigDecimal("80.50"), "USD",

"sku-12345"),

new PayPalItem("item #2", 2, new BigDecimal("10.00"),

"USD", "sku-311231"),

new PayPalItem("item #3", 1, new BigDecimal("3.99"),

"USD", "sku-222111"),

new PayPalItem("Discount #4", 5, new BigDecimal("-3.00"),

"USD", "sku-000000")

};

BigDecimal subtotal = PayPalItem.getItemTotal(items);

BigDecimal shipping = new BigDecimal("17.30");

BigDecimal tax = new BigDecimal("3.47");

PayPalPaymentDetails paymentDetails = new PayPalPaymentDetails(shipping, subtotal, tax);

BigDecimal amount = subtotal.add(shipping).add(tax);

PayPalPayment payment = new PayPalPayment(amount, "USD", "items", paymentIntent);

payment.items(items).paymentDetails(paymentDetails);

payment.custom("This is text that will be associated with the payment that the app can use.");

return payment;

}
