    payPalButton = findViewById(R.id.payPalButton);

    payPalButton.setup(
            new CreateOrder() {
                @Override
                public void create(@NotNull CreateOrderActions createOrderActions) {
                    ArrayList purchaseUnits = new ArrayList<>();
                    purchaseUnits.add(
                            new PurchaseUnit.Builder()
                                    .amount(
                                            new Amount.Builder()
                                                    .currencyCode(CurrencyCode.USD)
                                                    .value("10.00")
                                                    .build()
                                    )
                                    .build()
                    );
                    Order order = new Order(
                            OrderIntent.CAPTURE,
                            new AppContext.Builder()
                                    .userAction(UserAction.PAY_NOW)
                                    .build(),
                            purchaseUnits
                    );
                    createOrderActions.create(order, (CreateOrderActions.OnOrderCreated) null);
                }
            },
            new OnApprove() {
                @Override
                public void onApprove(@NotNull Approval approval) {
                    approval.getOrderActions().capture(new OnCaptureComplete() {
                        @Override
                        public void onCaptureComplete(@NotNull CaptureOrderResult result) {
                            Log.i("CaptureOrder", String.format("CaptureOrderResult: %s", result));
                            Log.i("CaptureOrder", String.format("CaptureOrderResult: %s", approval.getData().getOrderId()));
                            Log.i("CaptureOrder", String.format("CaptureOrderResult: %s", approval.getData().getPaymentId()));
                            Log.i("CaptureOrder", String.format("CaptureOrderResult: %s", approval.getData().getPayerId()));

                            

                        }


                    });



                }
            }

    );

Answer 1

Finally, I found the solution :

1. In the new PayPal Native-Checkout Android SDK, they don't provide paymentId; you can only get PayerId and OrderId
2. I use the OrderId; I send the OrderId to my server then. I use PayPal PHP SDK V2 to get the Order details response, which has PaymentId and all other payment information.

Answer 2

It will not be in the approval object, it will be in the capture result since it is created after capture. You are already logging the result so you should see the data there or via one of its methods.

Look for a capture id, which has the same 17 alphanumeric format as an order id but is a different value. The capture id corresponds to the PayPal transaction id used for accounting purposes in PayPal.com details , reports, and email notifications to the receiver.

(The order id is only used during approval and there is no reason to store it permanently, it's only useful for debug purposes)
