android - BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED : and revalidation of the purchase

Question

如果应用中的购买调用 BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED:需要调用

acknowledgePurchase(...

重新验证订单的功能？

Answer 1

acknowledgePurchase() 不允许重复购买一件商品。

一个项目不能被购买两次，为了能够再次购买它必须先调用 billingClient.consumeAsync()

acknowledgePurchase() 需要在购买成功后的短时间内调用，即 billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK 和 purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED 不这样做会使购买退款。

如果您在等待验证时尝试再次购买，但在返回 之前不调用 acknowledgePurchase()，则购买可能会返回 BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK和purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED
