【问题描述】：

我在使用 Google 应用内购买时遇到了一些问题。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，没有要求任何退款，但即便如此，72 小时后还是退款了。

    mBillingClient = BillingClient.newBuilder(MainActivity.this).setListener(this).enablePendingPurchases().build();
    mBillingClient.startConnection(new BillingClientStateListener()

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，您 必须在三天内确认所有购买。未能正确 确认购买会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);
        
    

【讨论】：

用户在我们的应用中支付了应用内购买，但谷歌在 72 小时 10 分钟后自动退款，我不知道为什么会发生这种情况。我将所有代码作为颤振文档进行，并在下面添加（app/build.gradle）依赖项 implementation 'com.android.billingclient:billing:2.0.3' 但每次用户用户支付应用内购买但谷歌自动72 小时和 10 分钟后退款。请问有什么解决办法吗？ （颤振应用）

即使添加了付款也会退还。对此有任何想法吗？
