Unity IAP - android.test.purchased not being consumed?

Hello,

I'm trying out the Unity IAP solution for Android. I'm using the product id: "android.test.purchased" which is a special product id that can be used for testing to simulate an actual purchase. But the problem with this is, that, once it has been bought it can't be purchased again, which is troublesome when testing.

Is there some way we can explicitly consume a product, is this a bug or how are you gonna handle this issue? According to this Stackoverflow: http://stackoverflow.com/questions/13896666/in-app-billing-test-android-test-purchased-already-owned they recommend that one consume the product, so that it can be used again.

Thanks!

 

Unity IAP automatically consumes consumable products on google play when your app confirms a purchase as processed.

Thank you, but I don't see how this helps me.

Unless something is wrong with the purchase I will return "PurchaseProcessingResult.Complete". Therefore, according to what you said, it should be consumed. But it doesn't because it's not a "normal" consumable, rather, I think it's more like a non-consumable and Unity IAP must make it a special case when handling it (or let us manually consume any products).

 

In version 3 api google for sales of products in applications, it supports only two types of products. Manageable products and signature products. Already Unity IAP has three products. Manageable, signature and consumables, and this has caused tremendous confusion in my head, because I see in posts around, it is necessary to consume the product after the purchase is completed. Some suggest the use of "m_Help.ConsumeAsync ()" method to do the job, but I have no IDEA how to implement it in a C # code. The version of my Unity is 5.3.3 and do not know if the new version of Unity supports this method. What needs to be exclarecido then, is how to simulate consumables in Unity IAP when Google Play supports only the signature products and manageable?

 

Can someone respond to this? How do you "consume" a managed product when using Unity IAP for Google Play, so that the user can purchase it again?

 

"Unity IAP automatically consumes consumable products on google play when your app confirms a purchase as processed."

We too are seeing a problem where it doesn't seem to be happening:

The code looks kind of like this...


public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
{
Product pp;
pp = args.purchasedProduct;
Debug.Log("IAP calledback from store to ProcessPurchase! --> " +pp.definition.id);
Debug.Log("IAP being careful to use the store-specific for verification: " +pp.definition.storeSpecificId);

PurchaseSUCCESSFUL( pp ); // our own routine to pay out the coins...
return PurchaseProcessingResult.Complete;
}

It seems that "return PurchaseProcessingResult.Complete;" is not having any effect, at the end.

It's like you can only buy a given consumable ONCE; on further attempts to buy that consumable it just returns immediately.

Anyone else seeing this??

 

Unity 5.4.3

I face with the same problem now, the same code flow work ok on iOS but not ok on android.
For me, in the method

public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgse)

I won't return PurchaseProcessingResult.Completed immediately, because I need to do receipt validation with my server so it will return PurchaseProcessingResult.Pending;

Then later when the validation succeed, I will call ConfirmPendingPurchase(e.purchasedProduct);
This flow work completely ok on iOS but not Android.

The first time I purchased the Managed/comsumable item it was ok, but then the second time I make purchase, I always received the receipt data of previous success purchase and thus my server always return "Receipt already used" because it tracked all the verified receipt data.

At first I tested the game using test account (google email added to the list of test users) that was allowed to make purchase without real money charge, later I remove this email from the list, deleted the app and download it from CH play again, but the problem still existed.

Here is the code I have, Unity guys please have a look, this bug still occur until now, December 9th 2016.

Code (CSharp):

1. public PurchaseProcessingResult ProcessPurchase (PurchaseEventArgs e)
2.     {
3.         Debug.Log ("Purchase OK: " + e.purchasedProduct.definition.id);
4.         Debug.Log ("Receipt: " + e.purchasedProduct.receipt);

9.         {
10.             if (cbFail != null)
11.             {

*Bump*
I have the exact same problem than emperor1412 just above, with Unity 5.5.2p1. I step-debugged and saw that I indeed call ConfirmPendingPurchase on the right product. However, next time I want to buy the product, I see a log "Already recorded transaction <some-hash-of-the-receipt>" and I received a PurchaseFailed event with PurchaseFailureReason.DuplicateTransaction. It happens each time, until I restart the app -- from the moment I quit and relaunch my app, I can buy the same item again. It's like Unity IAP only consume products on application exit

Could someone please help? Is this a known issue?

EDIT: I caught the "DuplicateTransaction" error and ignored it. Unity IAP and google play then allow me to buy the same consumable item again and again, even if it still outputs the "Already recorded transaction" log... So this seems like a Unity bug, where unity would confirm the purchase on google's end, but would not confirm the purchase in its cache until the app reboot...

 

Just to chime in that I'm seeing the same issue on 5.5.1p4 - a user made two purchases of different IAPs on Android. On attempting a third, it's refusing with a message:

msg: Couldn't purchase UnityEngine.Purchasing.Product, reason: DuplicateTransaction​

 

Hello,

Someone found the solution to the problem, I also have the same.

The worst thing is that if the player closes the application and re-enters the store even if he does not buy anything, he ends up receiving the value of the last purchase made.

Thank you,

Mauricio.

 

@Aurore hi this bug still occur after almost 1 year reported, please check it

 

I get this problem in version 2017

 

Same problem here (Unity 2017.2.0f3)

 

same here 2017.3.0f3 IAP services 1.15.0

 

For those reporting "same here", can you elaborate on your issue? The common issue in this thread looks to be the Duplicate Transaction issue, can someone confirm? Also, probably better to post in the Unity IAP forum at https://forum.unity.com/forums/unity-iap.112/
