[Solved] IAP : ArgumentException thrown at Initialize on Android

Hi guys,

The purchasing system seems to throw an ArgumentException "An element with the same key already exists in the dictionary" at initialization. I tested with 2 different devices (both on Android) with no success. But it works fine on editor.
Anyway, beginning of my code is :

Code (CSharp):

1. void Start()
2.     {
3.         if (m_StoreController == null)
4.         {
5.             InitializePurchasing();
6.         }
7.     }
8.  
9.     void InitializePurchasing()
10.     {
11.         if (IsInitialized())
12.         {
13.             return;
14.         }
15.  
16.         // Create a builder, first passing in a suite of Unity provided stores.
17.         var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
18.  
19.         // Add a product to sell / restore by way of its identifier, associating the general identifier with its store-specific identifiers.
20.         builder.AddProduct(kProductID0, ProductType.Consumable, new IDs() { { kProductNameAppleConsumable, AppleAppStore.Name }, { kProductNameGooglePlayConsumable, GooglePlay.Name } });
21.         builder.AddProduct(kProductID1, ProductType.Consumable, new IDs() { { kProductNameAppleConsumable, AppleAppStore.Name }, { kProductNameGooglePlayConsumable, GooglePlay.Name } });
22.         builder.AddProduct(kProductID2, ProductType.Consumable, new IDs() { { kProductNameAppleConsumable, AppleAppStore.Name }, { kProductNameGooglePlayConsumable, GooglePlay.Name } });
23.         builder.AddProduct(kProductID3, ProductType.Consumable, new IDs() { { kProductNameAppleConsumable, AppleAppStore.Name }, { kProductNameGooglePlayConsumable, GooglePlay.Name } });
24.         builder.AddProduct(kProductID4, ProductType.NonConsumable, new IDs() { { kProductNameAppleNonConsumable, AppleAppStore.Name }, { kProductNameGooglePlayNonConsumable, GooglePlay.Name } });
25.         Debug.Log("Trying to initialize");
26.         UnityPurchasing.Initialize(this, builder);
27.     }
28.  
29.       bool IsInitialized()
30.      {
31.         return m_StoreController != null && m_StoreExtensionProvider != null;
32.      }

I can't even get a OnInitializedFailed callback. The only piece of information I have on my console is :

Of course, all my keys are different strings.
Help !!

 

Okay, I think I had misunderstood something with the builder.AddProduct instruction. To do

Code (CSharp):

1. builder.AddProduct(kProductID0, ProductType.Consumable, new IDs() { { kProductNameAppleConsumable, AppleAppStore.Name }, { kProductNameGooglePlayConsumable, GooglePlay.Name } });
2.         builder.AddProduct(kProductID1, ProductType.Consumable, new IDs() { { kProductNameAppleConsumable, AppleAppStore.Name }, { kProductNameGooglePlayConsumable, GooglePlay.Name } });

is actually a mistake, right ? The "IDs" parameter is to specify the key on one store specifically. But if the key is the same on all stores, I can simply call

Code (CSharp):

1. builder.AddProduct(kProductID0, ProductType.Consumable);

Am I right, now ?

 

Hi @AlexIndeegoGames,

Yep, you are correct and well on your way!
