CrossInAppBilling.Current.AcknowledgePurchaseAsync has error

[mohammadrezahamedi]

Hello this code await CrossInAppBilling.Current.AcknowledgePurchaseAsync(purchase.PurchaseToken); has this error 'IInAppBilling' does not contain a definition for 'AcknowledgePurchaseAsync', and no accessible extension method 'AcknowledgePurchaseAsync' accepting a first argument of type 'IInAppBilling' could be found I even tested this code
billingResult = await billingClient.AcknowledgePurchaseAsync(acknowledgePurchaseParams).ConfigureAwait(false); and this code: var consumePurchase = await CrossInAppBilling.Current.ConsumePurchaseAsync(purchase.PurchaseToken, ItemType.Subscription.ToString());

All of the returns false or null, and the purchase cancel after 3 minutes

How to fix that?

Version Number of Plugin: 6.7.0 Device Tested On: Android Version of VS: 2022

Oh I think that was the solution :) var ack = await CrossInAppBilling.Current.FinalizePurchaseAsync(purchase.TransactionIdentifier).ConfigureAwait(false); Console.WriteLine(ack);

I used this code to acknowledge the purchases, but all purchases are in the "Chargeable" status. Why?

Correct in 6.X this API changed to FinalizePurchase.

Chargeable will be there if you are in test mode I am pretty sure. https://stackoverflow.com/questions/28014059/android-in-app-purchase-order-status-chargeable

Hi james Thanks for your reply. But this is not about the developer test. I published the app as a production version, and I get the "Chargeable" status for every purchase the user makes.

Please take a look at my code and see there is any problem with it code this code calls every time that the app runs :

`
public async Task RestorePurchases(string productIdSub) { if (_isBusy) return; _isBusy = true;

        try
        {
            var connected = await CrossInAppBilling.Current.ConnectAsync();
            if (!connected)
                return;
            var purchases = await CrossInAppBilling.Current.GetPurchasesAsync(ItemType.Subscription);

            if (purchases != null)
            {
                var isSubscribed = purchases.Any(p => p.ProductId == productIdSub && p.State == Plugin.InAppBilling.PurchaseState.Purchased);
                var purchase = purchases.OrderByDescending(i => i.TransactionDateUtc).FirstOrDefault();

                if (isSubscribed)
                {
                    var ack2 = await CrossInAppBilling.Current.FinalizePurchaseAsync(purchase.TransactionIdentifier);//before checking if subscriber or not
                    if (purchase != null)
                    {
                        main.RunOnUiThread(() =>
                        {
                            PurchasedUI(purchase.Id, purchase.State.ToString());
                        });
                    }
                }
            }

        }
        catch (InAppBillingPurchaseException purchaseEx)
        {

            var purchaseError = purchaseEx.PurchaseError;

        }
        catch (Exception ex)
        {
            // Handle other exceptions here
        }
        finally
        {
            _isBusy = false;
            await CrossInAppBilling.Current.DisconnectAsync();

        }

    }
