Bug Unity IAP 4.6.0 No such proxy method: onBillingServiceDisconnected()

I just updated to IAP 4.6.0 (Unity 2021.3.18f1) and got a lot of

Code (CSharp):

1. Exception: No such proxy method:UnityEngine.Purchasing.BillingClientStateListener.onBillingServiceDisconnected()

Exception in Unity's Cloud Diagnostics. (I don't see the error in crashlytics)

Almost all of them happens more than a 30 minutes after the game was sent to the background.

I never had this issue in version 4.5.2.

What can be wrong?

 

Hi @aVerrecchia

I am using higher versions of the packages:
Core: 1.7.1
Analytics: 4.3.0

- The Stack Trace field is emtpy in the Cloud Diagnostic, see the attached screenshot (disconnect2.png). I see some warning, but it is not related to this problem and you can see how far apart are the times.(disconnect3.png). Maybe the game sent to the background and some time later the billing library sends the disconnect event?
- No, I am not able to reproduce it locally.
- I don't think it crashes the game, but I see some ANRs at Crashlytics related to purchasing.

I updated to Unity 2021.3.19f1, but I still get the message.


What is "No such proxy method" means?

Can I subscribe to the onBillingServiceDisconnected event somehow?

UPDATE: it seems like it's causing crash sometimes.

Code (CSharp):

1.  
2. "stack": [{
3.         "func": "c:com.unity3d.player.ReflectionHelper m:nativeProxyLogJNIInvokeException",
4.         "file": "null",
5.         "line": -2
6.     }, {
7.         "func": "c:com.unity3d.player.ReflectionHelper m:a",
8.         "file": "null",
9.         "line": 0
10.     }, {
11.         "func": "c:com.unity3d.player.ReflectionHelper$1 m:invoke",
12.         "file": "null",
13.         "line": 55
14.     }, {
15.         "func": "c:java.lang.reflect.Proxy m:invoke",
16.         "file": "Proxy.java",
17.         "line": 913
18.     }, {
19.         "func": "c:$Proxy16 m:onBillingServiceDisconnected",
20.         "file": "null",
21.         "line": -1
22.     }, {
23.         "func": "c:com.android.billingclient.api.zzaf m:onServiceDisconnected",
24.         "file": "com.android.billingclient:billing@@4.0.0",
25.         "line": 4
26.     }
27. ]
28.  
29.  

 

Thanks for the info, when can we expect the update?

 

We are having this error alot. Very disappointing to see Unity missing out of such a frequent bug.

We will now have to degrade our plugin, re-do all the testing and push a new build.

 

@agorain @aVerrecchia Will 4.7.0 be available today as expected?

 

has it been released? I still don't see updates in my unity editor

 

You need to add it manually: Package Manager > "+" > Add package by name ... > com.unity.purchasing > 4.7.0.

 

thank you!

 

@agorain @aVerrecchia We just released an update that includes 4.6.0, and we are seeing this exception a lot in production. I wonder if you could elaborate on the expected side effects? Will players notice the issue? Will purchasing be broken for them? Will there be app crashes (either user visible or 'behind the scenes' when the app is in the background)? What determines if players are affected or not (or is it all players?). We're reluctant to release a hotfix update unless it's necessary to, as the release we just pushed out was already a hotfix, and we don't want to overwhelm players with updates. Thanks in advance,

Andy

 

@agorain Okay, thanks for the information; I guess we will need another update then.

 

Hi guys, we have this issue again after updating to Purchasing 4.9.3 on Unity 2021.3.29f1.

No such proxy method: UnityEngine.Purchasing.SkuDetailsResponseListener.onSkuDetailsResponse(UnityEngine.AndroidJavaObject,null)

Is there a quick way how to fix it? By a custom modifications in Purchasing package?
Thanks you

 

unfortunately, this thread fixes another problem... and now I'm seeing this error:
No such proxy method: UnityEngine.Purchasing.SkuDetailsResponseListener.onSkuDetailsResponse(UnityEngine.AndroidJavaObject,null)

 

Hi, I got this on canceling the subscribe payment page.
Exception: No such proxy method: UnityEngine.Purchasing.GooglePurchaseUpdatedListener.onPurchasesUpdated(UnityEngine.AndroidJavaObject,null)

 

me too....

 

Unity 2021.3.29
In App Purchasing 4.9.4
Error:
Non-fatal Exception: java.lang.Exception: Exception : No such proxy method: UnityEngine.Purchasing.SkuDetailsResponseListener.onSkuDetailsResponse(UnityEngine.AndroidJavaObject,null)

 

This should be a problem caused by this "fix":

https://forum.unity.com/threads/exceptions-after-uum-30243-fix.1465151/

I'm testing right now with Unity 2022.3.4f1 LTS , before this "fix".

• Android: AndroidJavaProxy correctly maps null variables (e.g empty string) for reflection search + automatic tests for AndroidJavaProxy. (UUM-30243)

Hi! The same error reported by my app users. Any fixes/workarounds?

 

@Arnaud_Gorain
@i9mobile
Hi! Yes UUM-30243 causes issues with IAP.

In my case, OnPurchaseFailed (I expect PurchaseFailureReason.DuplicateTransaction) is not called in Unity 2022.3.8 and there is the error in logs:
Exception: No such proxy method: UnityEngine.Purchasing.GooglePurchaseUpdatedListener.onPurchasesUpdated
when purchasing an item that was purchased before (PurchaseFailureReason.DuplicateTransaction is expected but not received)

But OnPurchaseFailed is called in Unity 2022.3.4 (the latest version with no UUM-30243)

The issue doesn't depend on IAP version (tested witn 4.7.0, 4.8.0, 4.9.4)

I've created the bug IN-52913

 

Hi! The same error reported by my app users. After reload device starting work, but after any time bug again

 

Hello! We're still waiting for Unity 2021.3.31 where this bug should be fix. Do you know when it's planned to be available?

 

We have softlunch very soon, we’ve been waiting for half a month, an update has already been released for 2022, there is no update for 2021. We'll have to risk switching to 22

 

Thanks! We saw, it's OCT 4.
