Unity_IAP_2.2.4 and Core Package 2.2.1 Play Store Errors

Unity Services
1

On Play Store
— PurchaseCanceled and PurchaseError messages are always empty or null ----

2

I’m not seeing this. I just tried to purchase a product not yet defined on the store, and I got a valid failureReason in the OnPurchaseFailed callback as expected saying “Not purchasing product, either is not found or is not available for purchase.” I’m testing the same version as you mention with the Sample IAP Project here Sample IAP Project . I also tested cancel and receive “UserCancelled”. Can you provide more information?

When the purchase is failed on Play Store,

m_TransactionHistoryExtensions.GetLastPurchaseFailureDescription() = null or
m_TransactionHistoryExtensions.GetLastPurchaseFailureDescription().message is empty/null

in the function → public void OnPurchaseFailed(Product item, PurchaseFailureReason r)

I’m checking PurchaseFailureReason r only, is there a reason you are calling the API additionally? Was this working in a previous IAP version for you?

→ Yes it was working in Unity_IAP_2.1.1

→ There is no specific reason to use the API.

Hello @ex-nihilio

Indeed this is no longer used in the new implementation of Google. That being said maybe your use case was not covered with our changes. Would you kindly explain the use case you have to call these extensions method instead of using the callbacks you receive from OnPurchaseFailed?

It might be something we over looked when shipping Google Billing v3 or there might be a change that wasn’t clearly described.

Please let us know what you are trying to do and we will work towards making it possible.

====
Here is a more detailed explanation of why it is no longer a thing.

Before IAP 2.2.0, we were using Google AIDL which will be deprecated and removed in 2021 by Google.

Starting from IAP 2.2.0 we switch over to Google Billing v3. This switch was MASSIVE and some features are combined now on Googles side, so we followed suit.

On a more technical note here but before the Google AIDL version was purely java and had to convert ever call to JSON to talk to our C# layer. Now it’s full C# so no more converting back and forth between layers. In this JSON converter was where we stored a local variable to handle the method GetLastPurchaseFailureDescription.

I have a crash report from Google Play as below,

java.lang.NullPointerException

We would need additional information and steps to reproduce.
