The type or namespace name 'IStoreListener' could not be found

I think my project is corrupt.

Tried to install IAP from Services tab as well as Asset Store, but I keep getting errors such as

The type or namespace name 'IStoreListener' could not be found (are you missing a using directive or an assembly reference?)

 

Please provide more information, what version of Unity and what version of IAP. The latest IAP version is 1.22. And avoid Unity 2019 with IAP (for now). Please follow the 2 minute video here for what you should expect when importing IAP, specifically the API update prompt, you must select "Yes, I have made a backup". https://forum.unity.com/threads/sample-iap-project.529555/

 

Thank you very much.

I'm using 2019.1.4f1 and I'm not sure what version of IAP is. I used Services tab IAP.
Do you know what specific version of 2019 we should avoid (with IAP)?

 

I did not mention a specific version for 2019, but you would want to use 2018 for now.

 

I re-installed 2018 and it is working now. Thank you.

For some reason I had to Import Services tab IAP and Package Manager In-App Purchase in order for it to work.

Will you be able to confirm if i have to install both like that?

 

Yes, both are required.

 

What all packages did you have to import to make it work? Please tell...

 

Are you receiving an error? The IAP installer should install the Asset store plugin 1.23.1 and the "In App Purchasing" Version 2.0.6 in Package Manager

 

I am still receiving the error "Type or namespace iStoreListener could not be found."

 

Please try installing IAP on a new project to compare. Or reinstall on this project, make a back up first. Even better, use this Sample IAP project https://forum.unity.com/threads/sample-iap-project.529555/

 

I have an project in which the same error occur plz tell me I have to I import you file for resolve it

 

The same recommendations apply. Often restarting Unity will help also. Ensure you are using IAP 2.2.7 Asset version (menu Window/Unity IAP/IAP Updates..) and In App Purchasing Library 2.2.2 (Package Manager)

 

Same problem with Unity 2020.3.47f
In App Purchasing 4.7.0

 

You can't be serious right ?

 

Same problem Unity 2022.2.15 / IAP 4.7.0

I added this and fixed

 

Not resolved, I had version 4.3.0 and everything worked fine, updated to 4.8.0 and got this error that never happened

 

Code (CSharp):

1. public void OnInitializeFailed(InitializationFailureReason error, string message)
2. {
3. // Implementation for new version
4. }

this solved the problem

 

I got same error in "com.unity.purchasing" version "4.10.0" PROBLEM IS STILL EXIST. PLEASE FIX IT. PLEASE LOOK AFTER WHAT YOU DONE. Don't you have quality control crew???????

And i realise oh i replied 8 months before and solved myself, now i am still came back for solution.
