[Closed] Google Play IAP Button no response.

Unity Services
1

Description of issue:
I’ve put my project into Alpha publication on the Google Play store, and I’m not able to get the codeless IAP buttons to respond. In the editor, they do respond and send me to Fake Store as expected (Although I should note that in editor I am having THIS separate issue, that maybe is related???).

Sorry to reply to my own thread, but reading and reading to find my mistake, I came across the following, and think it may be my mistake… can anyone confirm that the behavior described above would be caused by this:

SOURCE

EDIT: Nope, not my problem, non publisher account does same thing.

@rogaroga ,

Your log is showing a Null Reference Exception when clicking the button. Could you double check that all of your references are set properly.

4

In the editor pressing the button pops open the Fake Store with the option to buy or cancel. How can that be happening and then still have a null reference in game after building?

I found my problem with the references. In my above code, I didn’t specifically reference my googleplay ID for each product, just the general handler for each product. Updated code that does work:

    public static string Coins150 = "150coins";
        public static string Coins900 = "900coins";
        public static string Coins2000 = "2000coins";
        public static string Coins5000 = "5000coins";
        public static string Coins30000 = "30000coins";

        // Apple App Store-specific product identifier.

        // Google Play Store-specific product identifier.
        private static string kProductNameGooglePlayCoins150 = "150coins";
        private static string kProductNameGooglePlayCoins900 = "900coins";
        private static string kProductNameGooglePlayCoins2000 = "2000coins";
        private static string kProductNameGooglePlayCoins5000 = "5000coins";
        private static string kProductNameGooglePlayCoins30000 = "30000coins";

        void Start()
        {
            // If we haven't set up the Unity Purchasing reference
            if (m_StoreController == null)
            {
                // Begin to configure our connection to Purchasing
                InitializePurchasing();
            }
        }

        public void InitializePurchasing()
        {
            // If we have already connected to Purchasing ...
            if (IsInitialized())
            {
                // ... we are done here.
                return;
            }

            // Create a builder, first passing in a suite of Unity provided stores.
            var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

            // Add a product to sell / restore by way of its identifier, associating the general identifier
            // with its store-specific identifiers.
            builder.AddProduct(Coins150, ProductType.Consumable, new IDs(){ {kProductNameGooglePlayCoins150, GooglePlay.Name} });
            builder.AddProduct(Coins900, ProductType.Consumable, new IDs(){ {kProductNameGooglePlayCoins900, GooglePlay.Name} });
            builder.AddProduct(Coins2000, ProductType.Consumable, new IDs(){ {kProductNameGooglePlayCoins2000, GooglePlay.Name} });
            builder.AddProduct(Coins5000, ProductType.Consumable, new IDs(){ {kProductNameGooglePlayCoins5000, GooglePlay.Name} });
            builder.AddProduct(Coins30000, ProductType.Consumable, new IDs(){ {kProductNameGooglePlayCoins30000, GooglePlay.Name} });

@rogaroga ,

This doesn’t look like any error I’ve seen before. Would you be able to send a sample project where this happens?
https://analytics.cloud.unity3d.com/support/

The FakeStore only works in the editor. The FakeStore is meant to simulate the platform stores that aren’t available in the Editor. Once you create a build for Android and iOS, you must use the product IDs that you created in the store.
https://docs.unity3d.com/Manual/UnityIAPAppleConfiguration.html
https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html

Another thing I didn’t notice before, if you are using Codeless IAP, then you don’t need to create a purchasing script. That is all handled by setting up the IAP Catalog and creating individual buttons.

This shouldn’t be necessary. The store-specific IDs are only needed in cases where you don’t have the same product ID across stores. For example, if your 500 gold coin product is called “500gold” in Google Play but “gold500” in iTunes, then you would need a store-specific ID to reconcile this. In your example, there should be no benefit to adding them.

If you are using the Codeless IAP, then you can see the purchasing script that is used in:
Plugins/UnityPurchasing/script/IAPButton.cs
