Google 应用内购买始终会退款

Question

我在使用 Google 应用内购买时遇到一些问题。所有收到的付款将在 72 小时后退还。我的付款代码有错误吗？我自己付了钱，没有要求退款，但即使是72小时后也退款了。

您似乎没有正确确认购买。

如果您使用 Google Play 结算库 2.0 版或更高版本，则必须在三天内确认所有购买。未能正确确认购买将导致这些购买被退款。

您可以在文档中找到更多详细信息：https://developer.android.com/google/play/billing/billing_library_overview#acknowledge

BillingClient client = ...
AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = ...

void handlePurchase(Purchase purchase) {
    if (purchase.getPurchaseState() == PurchaseState.PURCHASED) {
        // Grant entitlement to the user.
        ...

        // Acknowledge the purchase if it hasn't already been acknowledged.
        if (!purchase.isAcknowledged()) {
            AcknowledgePurchaseParams acknowledgePurchaseParams =
                AcknowledgePurchaseParams.newBuilder()
                    .setPurchaseToken(purchase.getPurchaseToken())
                    .build();
            client.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
        }
    }
}
