'GooglePlayStoreModule' does not exist in the namespace after Unity update

Hey guys!
I got the problem after upgrading Unity from 2020.1.17f1 to 2020.3.0f1.

I am updating my project to a newer version of Unity and Unity says
The type or namespace name 'GooglePlayStoreModule' does not exist in the namespace 'Google.Play.Billing' (are you missing an assembly reference?)
But everything is OK in my IDE. If I remove the code containing the GooglePlayStoreModule I get another error in Unity. Unity cannot find the abstract method MRGSMetrics.AddPurchase (Product PurchasingProduct), but it is there. And again in the IDE everything is OK.

In both cases AddPurchase and GooglePlayStoreModule inside #if UNITY_PURCHASING. Perhaps the error is somewhere here.

I have the latest version of GooglePlayPlugin v.1.4.0., Unity IAP is ON.

P.S. If I comment and uncomment the abstract method, the AddPurchase error goes away. This also happens with GooglePlayStoreModule. But after reopening Unity, both errors will appear again.

 

Make a project backup then delete your /Library folder. And you are using the GooglePlayPlugin? They may be duplicating libraries. Please test on a new project with IAP only to compare.

 

Thanks! I will try to do this later and then I will answer.

 

I also have same problem.
Everything works fine before update Unity IAP to 3.0.2
It seems that google.play.bill conflicts with IAP?

 

The same directions apply, compare to a new project https://forum.unity.com/threads/goo...pace-after-unity-update.1076585/#post-6944405 Note the release notes explain to delete previous folders

 

I did try everything,
Had try:
1. follow the release note
2. switching IAP & Google play billing version
3. open new project with only IAP & Google play billing

I think the problem might caused by IAP changing storage folder,
following the tutorial from https://developer.android.com/google/play/billing/unity
1.whether the google play billing conflict detection is correctly pointer to the right folder?
(with pic er2)
2.Is it necessary to use GooglePlayStoreModule to instance?
I can now receive information through StandardPurchasingModule.

Code (CSharp):

1.  
2. //Error
3. var builder = ConfigurationBuilder.Instance(Google.Play.Billing.GooglePlayStoreModule.Instance());
4. //Work
5. var builder2 = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());

 

Sorry I don't follow. So you tried with a new project? Please share your results. Don't install anything except Unity IAP, we install the Google billing library for you. The tutorial you are following is not from Unity, do not follow it. Perhaps start with the Sample IAP Project here https://forum.unity.com/threads/sample-iap-project.529555/

 

My problem has solved.
It's weird that this is not official tutorial,
your teams should let unity users know which tutorial they can follow,
this article come up first place by searching "unity iap google play bill",
misleading for those who want to integrate iap.

 

That is not our documentation! We have no control over the Google documentation. We are updating our documentation at https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html to point to the Sample IAP Project

 

Please, tell me what you've done to fix this issue ...
I had everything going, and after the last update, Google.Play namespace seems 'broken'.

#if UNITY_ANDROID
GooglePlayStoreModule module = (GooglePlayStoreModule)Google.Play.Billing.GooglePlayStoreModule.Instance();
var builder = ConfigurationBuilder.Instance(module);
#endif

Thanks in advance

 

Please open and compare to the Sample IAP Project v2. Note that you now need to remove Assets/Plugins/UnityPurchasing and use Package Manager (only) to update IAP. And Google.Play.Billing, where are you seeing the Unity documentation for this?

 

I do not have anything in Assets/Plugins/UnityPurchasing. I''ve updated In App purchases to latest version via UMP.
I can't find any consensual documentation.
I've tried even deleting the whole library folder.

Weirdly enough, that's the only thing in this namespace. I don't know what to do. I can't see anything in samples.

 

I meant, why are you adding that code? Where are you finding it? Please compare to the Sample IAP project as suggested.

 

I'm adding this code to initialize Google Play store module, when in Android, then to pass it to the ConfigurationBuilder class.

The code is as follows

Code (CSharp):

1. #if !UNITY_STANDALONE && !UNITY_ANDROID
2.                     StandardPurchasingModule module = StandardPurchasingModule.Instance();
3.                     var builder = ConfigurationBuilder.Instance(module);
4. #endif
5.  
6. #if UNITY_ANDROID
7.             var module = (GooglePlayStoreModule)Google.Play.Billing.GooglePlayStoreModule.Instance();
8.             var builder = ConfigurationBuilder.Instance(module);
9. #endif

But this package google.billing, apparently doesn't have this GooglePlayStoreModule and I can't get this to work.
I've looked at Sample Project v2 and I couldn't see anything related.

Thank you

 

Correct, it's not needed. Please use the working code from the Sample project. Where did you originally obtain the code that you are using?

 

I had this code working before. I got this init from this doc
https://developer.android.com/google/play/billing/unity

I've tried doing as the sample. Now I can compile, but can't see any product in the app. I'm trying to check if there is any other problem

 

Yes, you no longer want to use that code which was originally published by Google (not Unity). You'll want to use the code from the Sample project and follow the directions here https://docs.unity3d.com/Packages/com.unity.purchasing@3.2/manual/UnityIAPGoogleConfiguration.html

 

any proper fix for this? I'm using AIP 4.1.2 and billing 3.2.1

 

Can you confirm what code you are using and the exact error you are receiving?

 

I'm using unity AIP 4.1.2 and google play billing 3.2.1, its okay now it turns out you will need to add UNITY_PURCHASING custom define, then now got error in build getting errors

Did you add the Google Billing Library separately? We already include it, you are seeing duplicate libraries.
