Я использую Google In-app Billing Version 3 в своем Android приложении, я тестирую модуль заказа приложения на основе следующего кода.
В случае, если заказ пользователя был возвращен через Google Play, но когда я запускаю mBilling.initBillingClient(), я обнаруживаю, что purchase.purchaseState == Purchase.PurchaseState.PURCHASED в private fun processPurchases запущен.
Кажется, что заказ со статусом Refunded как PURCHASED успешно, как я могу это исправить?
