Question

我的片段中有下一个代码（不是所有代码，而是一般部分）：

public void BuySubscription(int number)
    {
        string vvalue = Security.Unify(
              new string[] {
                    SpecialStringOne,
                    SpecialStringTwo,
                    SpecialStringThree,
                    SpecialStringFour,
                    SpecialStringFive,
                    SpecialStringSix,
              new int[] { 3, 2, 0, 5, 1, 4 });

        _serviceConnection = new InAppBillingServiceConnection(Activity, vvalue);

        _serviceConnection.OnConnected += async () =>
        {
            await GetInventory();

            _serviceConnection.BillingHandler.OnProductPurchased += delegate
            {
                // Reaction if product was bought  
                ExtraTools.StringWorker.ShowMessage("I have bought it!", false);               
            };

            _serviceConnection.BillingHandler.BuyProduct(products[number]);
        };

        _serviceConnection.Connect();
    }

我从未获得OnProductPurchased事件。

这是MainActivity中的通用代码：

protected override void OnActivityResult(int requestCode, [GeneratedEnum] Result resultCode, Intent data)
    {
        Fragments.BillingFragment billingFragment = new Fragments.BillingFragment();
        base.OnActivityResult(requestCode, resultCode, data);
        if (billingFragment != null)
        {
            try
            {
                Fragments.BillingFragment._serviceConnection.BillingHandler.HandleActivityResult(requestCode, resultCode, data);
                int code = data.GetIntExtra("ResponseCode", 2);
            }
            catch (NullReferenceException exc)
            {
                Toast.MakeText(Application.Context, "Some error occurred", ToastLength.Short).Show();
            }

        }
    }

片段内部有什么问题？请帮帮我。

我从未想过它可能是我的问题的原因，但当我从MainActivity中删除 LaunchMode = LaunchMode.SingleInstance 时，我已经被要求举办活动。

非常奇怪！

Xamarin.Android In-App Billing OnProductPurchased无法正常工作
