Я бы хотел, чтобы пользователь мог покупать монеты, но после нажатия кнопки платежа повторное нажатие не запросит новую покупку, а просто добавит новые монеты.Я использую " android-inapp-billing-v3 " для своей покупки.Я очень благодарен за вашу помощь.Если он не создает комитеты, я также очень благодарен, если кто-нибудь покажет мне, как я могу запросить несколько групп монет в приложении и выполнить соответствующий код.
Вот мой код MainActivity.class:

BillingProcessor bp;
