Problem with IAP restore google play

Questions & Answers

Hi,

I have a problem with restoring already purchase a nonconsumabe product with Unity IAP on Android.
They say in the documentation that it suppose to happen during initialization. But when I check if it has a Receipt, I get return false.

Here is code:

using System;
using UnityEngine;
using UnityEngine.Purchasing;

public class IAPmanager : MonoBehaviour, IStoreListener
{
    private static IStoreController m_StoreController;
    private static IExtensionProvider m_StoreExtensionProvider;


    //private static string AppleNonConsumable = "";
    private static string GooglePlayNonConsumable = "noADS";

    void Start()
    {
        if (m_StoreController == null)
        {
            InitializePurchasing();
        }
    }


    public bool isBought(){
        bool status = m_StoreController.products.WithID(GooglePlayNonConsumable).hasReceipt;
        return status;
    }

    public void InitializePurchasing()
    {
        if (IsInitialized())
        {
            return;
        }

        var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

        builder.AddProduct(GooglePlayNonConsumable, ProductType.NonConsumable);

        UnityPurchasing.Initialize(this, builder);
    }


    private bool IsInitialized()
    {
        return m_StoreController != null && m_StoreExtensionProvider != null;
    }


    public void BuyNonConsumable()
    {
        BuyProductID(GooglePlayNonConsumable);
    }


    void BuyProductID(string productId)
    {
        if (IsInitialized())
        {
            Product product = m_StoreController.products.WithID(productId);

            if (product != null && product.availableToPurchase)
            {
                Debug.Log(string.Format("Purchasing product asychronously: '{0}'", product.definition.id));
                m_StoreController.InitiatePurchase(product);
            }
            else
            {
                Debug.Log("BuyProductID: FAIL. Not purchasing product, either is not found or is not available for purchase");
            }
        }
        else
        {
            Debug.Log("BuyProductID FAIL. Not initialized.");
        }
    }

    public void OnInitialized(IStoreController controller, IExtensionProvider extensions)
    {
        Debug.Log("OnInitialized: PASS");

        m_StoreController = controller;
        m_StoreExtensionProvider = extensions;
    }


    public void OnInitializeFailed(InitializationFailureReason error)
    {
        Debug.Log("OnInitializeFailed InitializationFailureReason:" + error);
    }


    public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
    {
        if (String.Equals(args.purchasedProduct.definition.id, GooglePlayNonConsumable, StringComparison.Ordinal))
        {
            Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
            PlayerPrefs.SetInt("IAP",1);
        }
        else
        {
            Debug.Log(string.Format("ProcessPurchase: FAIL. Unrecognized product: '{0}'", args.purchasedProduct.definition.id));
        }

        return PurchaseProcessingResult.Complete;
    }


    public void OnPurchaseFailed(Product product, PurchaseFailureReason failureReason)
    {
        Debug.Log(string.Format("OnPurchaseFailed: FAIL. Product: '{0}', PurchaseFailureReason: {1}", product.definition.storeSpecificId, failureReason));
    }
}

Same here! Certainly there is a bug, the function that process purchases are not being called at startup in my app. Need an urgent solution to this :frowning:

Same for us. Restore purchases is not working in Android, neither in iOS. In Android RestoreTransactions is not being called in app start. In iOS, calling

m_AppleExtensions.RestoreTransactions(OnTransactionsRestored);

through a restorepurchase button, does not prompt the user password dialog and always returns false.
