Xamarin InAppBilling订阅

Question

我正在尝试实施InAppBilling（Android）订阅。我尝试使用component（Xamarin.InAppBilling）。我可以购买订阅但当我试图通过订阅获得购买项目时，没有任何回报给我。您是如何实施IAB（Android）订阅的？有人举个例子吗？

public class PurchaseManager : IPlayListener

    MLActivity2 _act;
    BillingService m_service;
    int m_requestId = 1;

    //String _productId = "subscription.test";

    //atributos IAB
    String _publicKey = "";
    String _productId = "";
    public bool _premium;

    public PurchaseManager(MLActivity2 act)
    {
        _act = act;
        IniciarPurchase();
    }

    public void OnActivityResult (int requestCode, Result resultCode, Intent data)
    {
        m_service.HandleActivityResult(requestCode, (int)resultCode, data);

    {
        if (m_service != null)
            m_service.Dispose();

添加代码段始终有助于更快地获得正确答案。下次不要忘记;）

当您查询购买时，请确保使用正确的项目类型：订阅（而不是产品）。如果你有两个，你必须做两个查询 - 一个用于产品，一个用于订阅。
