ProcessPurchase called even if purchase was not completed

Thank you!

 

Awesome thanks for the help!

 

I'm still seeing this in IAP 1.23.5. In this log example, we already had one non-consumable item purchased and then attempted to purchase another after reinstalling but then hit the back button (cancelled) before making the purchase. Our own IAP_Fulfillment class logs the OnPurchaseFailed event, followed by the ProcessPurchase event on the same product.

Would a safe temporary work-around for this problem be to validate the transactionID on Google Play builds to make sure that it begins with "GPA." ?

We're already doing the following bits of validation on the GooglePlayReceipt but these are resulting in a valid purchase for these cancelled transactions:

1. Calling Validate() using the unity client-side validator.
2. Checking that productID matches the storeSpecificId for the product.
3. Checking that purchaseState == GooglePurchaseState.Purchased
4. Checking that the purchaseData is within a valid range.

 

Sure, here's the beginning of the log:

The productID (infinity_recharge) was displayed in the part of the log that I included. When the user cancelled the purchase of "infinity_recharge" a failed event (cancelled) and a purchase event was sent for the same product "infinity_recharge". The one listed as "Already recorded transaction" on startup is a completely different product ID, I'm 100% sure of this.

 

I've published a new build version that now validates that transactionID.StartsWith("GPA.") and this seems to be working for legitimate purchases and ignores the invalid purchase callbacks on user purchase cancellation. In summary, this is a work-around for what I consider a bug in UnityIAP 1.23

 

Have you had a chance to test with 1.23.5?

 

Yes, see my original post above from August 18th: "I'm still seeing this in IAP 1.23.5"

Hi, any updates on this issue?

 

No updates, still on the radar. Have you tried the aggressivelyRecoverLostPurchases flag in 1.23.5 or 2.0?

 

Yes, we're using aggressivelyRecoverLostPurchases = true with 1.23.5. This was the scenario under which cancelling the non-consumable purchase caused a ProcessPurchase() callback to fire on the Android device under Google Play.

 

am ..
Looks like a something new in 2020
Unity3d 2020.4.9
Android IL2CPP
Having some message afetr update to Unity IAP 2.1.0
after purchasing

Code (CSharp):

1. 09-03 15:15:45.506: I/Unity(17038): UnityIAP Version: 2.0.0

Code (CSharp):

1. 09-03 15:16:37.051: E/UnityIAP(17038): Unrecoverable consumption failure, transaction status will not be automatically handled further

 

Can you elaborate? How does this affect the purchase flow for you?

 

it message. it worries me.
application should not have error messages.

 

I'm confused, is this error message related to the this thread's subject, which is a bug in UnityIAP where the ProcessPurchase() callback is called when the user cancels the purchase? If not, then please Post A New Thread.

 

That is an information message only, we need to consider different wording.

 

I have this issue too but instead of restarting the application, the players get awarded with their purchases immediately. After clicking the buy button, there is a small pause before failing and then rewarding the player afterwards.

I know that it failed because I have 2 different audio that plays for purchase failure and success respectively. The purchase failed audio plays followed by the success audio shortly after. Purchases are also credited to the players.

 

What is causing the pause? Please debug, reproduce and provide the device logs.
