[Solved] ProcessPurchase event get called multiple times

Before I have purchased Weekly Subscription and now whenever I open my app again, ProcessPurchase event get called multiple times. Though this time I have purchased nothing.

See below xCode log for more clearance:


Now I have just open the app so no reason for event get called multiple times by itself.
As per my thinking, it should get call only one time when ever you make purchase something.
Then after there is no reason of this callback.

Mainly I was following this document and its code:
https://unity3d.com/learn/tutorials/topics/ads-analytics/integrating-unity-iap-your-game

Here is my snippet of code:

Code (CSharp):

1. public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs args)
2.     {
3.         if (String.Equals(args.purchasedProduct.definition.id, kProductIDPick_099, StringComparison.Ordinal))
4.         {
5.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
6.         }
7.         else if (String.Equals(args.purchasedProduct.definition.id, kProductIDPick_199, StringComparison.Ordinal))
8.         {
9.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
10.         }
11.         else if (String.Equals(args.purchasedProduct.definition.id, kProductIDPick_299, StringComparison.Ordinal))
12.         {
13.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
14.         }
15.         else if (String.Equals(args.purchasedProduct.definition.id, kProductIDPick_399, StringComparison.Ordinal))
16.         {
17.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
18.         }
19.         else if (String.Equals(args.purchasedProduct.definition.id, kProductIDPick_499, StringComparison.Ordinal))
20.         {
21.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
22.         }
23.         else if (String.Equals(args.purchasedProduct.definition.id, kProductIDWeeklySubscription, StringComparison.Ordinal))
24.         {
25.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
26.  
27.             SubscriptionActivated();
28.  
29.             //if (DataStorage.RetrieveLoggedInStatus() == GameConstants.ON)
30.             //    StartCoroutine(CheckForSubscriptionStatus());
31.         }
32.         else if (String.Equals(args.purchasedProduct.definition.id, kProductIDMonthlySubscription, StringComparison.Ordinal))
33.         {
34.             Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));
35.  
36.             SubscriptionActivated();
37.             //if (DataStorage.RetrieveLoggedInStatus() == GameConstants.ON)
38.             //    StartCoroutine(CheckForSubscriptionStatus());
39.         }
40.         else
41.         {
42.             Debug.Log(string.Format("ProcessPurchase: FAIL. Unrecognized product: '{0}'", args.purchasedProduct.definition.id));
43.         }
44.  
45.         return PurchaseProcessingResult.Complete;
46.     }
47.  
48. private void SubscriptionActivated()
49.     {
50.         GameManager.Instance.IsSubscriptionRunning = true;
51.         if (paidPickParser != null)
52.             paidPickParser.UnlockAllPaidPicks();
53.         Camera.main.SendMessage("ActivateSubscriptionDialog", false, SendMessageOptions.DontRequireReceiver);
54.     }

Before I have made purchase of Weekly Subscription.
Another point, why I was getting NullReferenceException through internal method? See above log image for more details.

 

The IAP team is looking into this. The NullReference exception may imply that the transaction is not completing properly, and may explain the repeated attempts. If it turns out to be an issue on our end, we will try to get it into a future release.

 

Thank you sir for your side quick reply.

Now please do something for this as early as possible because I have already launched the app into the market and its not functioning properly in subscription purchase.
So I require to update soon app regarding this.

One more question, why ProcessPurchase event get called multiple times ?

 

@siddharth3322 We believe the original transaction never completes (evidence from the NullReference exception), so we receive a repeated callback hoping to clear the pending transaction.

 

Now on every app launch ProcessPurchase method get called one time. So what is the reason behind this ??
Because now I have not purchased anything.

 

@siddharth3322 Can you elaborate? Are you logging in as a new user, or is this the same user with the weekly subscription? Please show your logs as before. What version of IAP are you using?

 

Basically at present I was using Sandbox apple store account for testing purpose. Using this account I have purchased weekly subscription before and it was successful for me but multiple tries happen for this purpose so I got multiple NullReferenceException and multiple time called of ProcessPurchase success call rather than PurchaseFail method call.
My iMac running little bit slow but I am giving you all details by attaching the device now.

Unity IAP Version: 1.14.1
Just 2 days ago, I have opened Unity and update related dialog box come so I have update that.

 

Here you have xCode log data, at present I have just loaded main page of application.



Now because of this problem - without any reason subscription purchase related code get executed.
So in free, app user can take benefit of subscription purchase.

Sir let me know any further help you want from me.

 

@siddarth3322 This looks like the original issue that you reported with the NullReferenceException. We are looking into it.

 

Thank you sir
Basically in above case all time, OnPurchaseFailed should require to get called.
On whichever transaction was successful that should only call ProcessPurchase method.
This is the actual solution for the problem.

Lets give me reply for following points so I become more clear in implementation:
1) if app user purchased weekly subscription and after 10 days he opened the app, then ProcessPurchase method get called or not ??
2) If ProcessPurchase method get called then is it my responsibility to check subscription active or not? Before giving advantage of subscription.
3) Giving subscription purchase advantage, at whichever place I have written activate subscription related code in above my mentioned snippet, is that correct place to write? because in real subscription purchase a person can't able to get success in unlocking things after subscription purchase was successful. Just payment get cut and no advantage he can able to get.

@siddarth3322 As mentioned, we are looking into this. Once we have more information, I will share it with you.

 

@siddarth3322 A null reference exception like you're seeing is typically a result of something being misconfigured in your application but we really can't assess that without additional information from you. First, what version of Unity and IAP plugin are you using? Second, are you using codeless IAP buttons or are you configuring your products manually using builder.AddProduct()? Are there any specific extension / plugin options you are setting in your application?

Can you provide the complete log from xcode from when the app starts through the errors? The screen shots you've provided here don't provide sufficient context and don't show what kind of configuration issues may have been encountered earlier in the setup process. The full log would also answer the Unity and IAP version questions for us.

What you're seeing with multiple process purchase calls is actually normal in the case of auto-renewing subscriptions. When you test in the sandbox those subscriptions renew very quickly (how fast depends on sub period) and you can often see several of those appear in the queue after an app restart. Also, if a purchase hasn't been successfully completed (which is likely given those exceptions) then they can remain in the queue and result in multiple calls to your ProcessPurchase on every app restart until the problem is resolved.

 

Thanks to whole Unity team for taking one request this much seriously and working into this.
For me this is really really important because sooner I require to publish new version of application.
Below I have mentioned one by one points reply those you mentioned above.

1) I was using this versions:
Unity 5.4.2p4
Unity IAP Plugin 1.14.1

2) Complete xCode log, from app launch to auto execution of ProcessPurchase method.

4) I understand your side provide information about subscription renewal process.
Basically queue was managed for all background or past transactions and when you launch the application, it get executed. But what to do if subscription time duration was already over??

In past transaction was happened so it will definitely call ProcessPurchase method, but in this method - I have written subscription benefit related code. So situation happen like, subscription time was over then also person get benefit of subscription.
So what to do in this case?? Any kind of manually checking is necessary.

Sorry for my so many questions but these are just for my clearance. I hope - I have provided your side required information. Waiting for your side new message.

 

I have given above all information properly and I hope you have check those.
When I get any reply from your side about this? Because I require to release new app version soon.
Also reply for my asked questions too.

 

As mentioned previously, we are investigating this. Once we have reproduced the issue in-house, we will create the task to address the issue and begin the code development. After that is done, the update will move to QA/Testing, and finally into a released updated version of IAP. We cannot guarantee which release this will be in, but hopefully within a few weeks. If sooner, we will certainly let you know.

 

Thank you sir for your quick reply
Few questions from my side:

• Basically you will concentrate on NullReferenceException into new plugin realise, Am I right?
• What to do for ProcessPurchase event get called multiple times for all renewable transactions in past?
• For this multiple method calls of ProcessPurchase event, I manage to deal with my custom server regarding the status of subscription by querying Apple server. But this IEnumerator didn't get called in real purchase so that I can get information through web service call. Though in Sandbox mode its working properly and getting response from my custom server but in real purchase IEnumerator didn't get called as per my thinking. Can you share your point of view about this?

 

Yes, those are the questions that we are investigating. I will keep you updated.

 

@siddarth3322 a few comments / questions for you:

1. Does your game continue to operate after you see the exception message in the logs? There are some exceptions that are caught and just printed to indicate potentially degraded performance. In particular, problems accessing the device file system could be an issue here.
2. If the game continues to run, can you successfully make a test purchase after seeing the exception?
3. If you disable your receipt checking (in your OnInitialized()) does that change behavior?
4. You may want to adjust your subscription checking process to include using the receipt provided to your ProcessPurchase() since that is arriving with the transaction. You can also perform on-device receipt validation at this point.
5. At a minimum try adding some debug to your ProcessPurchase() to print args.purchasedProduct.transactionID and possibly args.purchasedProduct.receipt to help match up what you're seeing on-device with the servers

 

Let me reply for above each point:

1. Yes game remain continue normally as like before.
2. Basically I have done both real and sandbox purchases and with both purchase process remain successful.
3. This point, I can't able to reply because I am not aware what exactly I require to do for this step!

   At above I have divided whole thing into two process. i) At actual purchase time, used local device receipt verification through DateTime object. ii) Then rest all game loading time, performed receipt validation through web server passing actual receipt data. In sandbox mode, I was getting time related data wrong so at present I can't able to say, I got success in implementation because 3 mins time interval is for Weekly subscription and 5 mins time duration for Monthly subscription purchase.
5. Okay I will deliver you a log information within short time.

 

One more point for discussion, why I was getting wrong time related entry in apple receipt response??
Above I have mentioned code that I was using but here you have complete log information too:



Usually Weekly subscription has 3 mins time duration so if I am not getting exact time then how can I do proper testing!!

In above image, I have mention both times, my local time is 15:01:04 and apple receipt response time is 09:37:18.
Using local device receipt validation at present I can't able to test the work. so what way exist for me for testing??

 

Regarding the Apple receipt times, you would want to contact Apple. They may be using artificial dates in the testing environment. Are the times always off by the same amount? If so, you could just subtract the proper time interval.

 

Thank you sir - I was waiting for your this reply.
Is this possible time difference related to GMT ??
I am at India so GMT time difference is 5:30.
Please check following two examples:

Weekly subscription purchase screenshot


Another different day purchase example.
Monthly subscription purchase screenshot


Share your opinion regarding this.

 

As mentioned, you would want to contact Apple regarding this. If the time is off by the same amount each time, you could adjust accordingly.

 

On-device the apple receipt times are GMT. Server validation returns both GMT and local times in the JSON. Sandbox subscriptions only auto-renew five times so your testing window on weekly subs in particular can be tight. Also worth noting that the expired subscriptions are not removed from the receipt so your previous tests will continue to appear as chunks of six expired entries.

What's the source of your server time and how is it synchronized? A significant difference in two server times would not be terribly surprising.

 

Hello Sir, after using Unity 2017.1.2 and latest Unity IAP plugin, multiple time calling of ProcessPurchase method get stopped. Now without any reason its not calling if in past background transaction occurred then only its get called.

But in Unity 5.4.2 version with latest Unity IAP plugin 100% there is some mistake exist because I have several proof too and few I have posted above. At present its okay, I have shifted my project to higher Unity version.

Now if you want to close this thread then you can because now I am satisfied with the output
Thank you for giving so much attention to this single thread!!!

 

This is very crucial information for auto-renewing subscriptions in the UnityIAP library. Thanks for explaining this, are there any more things we need to take into consideration with auto-renewable subscriptions?

Also an update to the documentation would be very helpful.

 

We are releasing an update soon that will include improved subscription support including an isSubscriptionActive boolean flag.

 

Is there any way to remove these hundreds of test subscriptions from the queue? (we have 830)

 

You would want to reach out to Google for your suggestion. We are a pass through service for the various stores. We would not want to remove their receipts from the store processing. You can configure a new test user who would not have any subscriptions yet.
