    Hello guys,
    we encounter some 'PurchasingUnavailable' and 'ProductUnavailable' errors on the Android platform. It seems to increase lately so we looked into it. But we couldn't really find anything.

    Here just quick the documentation definitions to get it out of the way:

    PurchaseFailureReason.PurchasingUnavailable
    The system purchasing feature is unavailable.
    Unity IAP may be disabled in security settings, or the system purchasing library may be outdated.

    PurchaseFailureReason.ProductUnavailable
    The product is not available to purchase on the store.
    Check the product definition in the store.

    About 0,5% of our Android customers encounter this problem (at least one of those problems but no pattern to spot here).
    It also seems not to be consequent, since some users who already payed before faced the problem afterwards.

    Since both documentation definition are just "abstract" (a lot of "may" ;)) and the "ProductUnavailable" should be consequent be thrown or not, we wonder if there is a way to dig further into it. It would be more then nice to be able to tell our customers what to do when facing such a problem.

    One stack trace we found during our research was the following:

    Unable to cache IAP catalog: System.UnauthorizedAccessException: Access to the path '/storage/emulated/0/Android/data/<bundle-id>/files/Unity/82d11ea9-91c6-4fe8-b5e3-8c8276dbb058/IAP' is denied. at System.IO.Directory.CreateDirectoriesInternal (System.String path) [0x00000] in <filename unknown>:0 at System.IO.Directory.CreateDirectory (System.String path) [0x00000] in <filename unknown>:0 at UnityEngine.Purchasing.UnityPurchasing.InstantiateCatalog (System.String storeName) [0x00000] in <filename unknown>:0

    We believe that this could be related to this problem.


    Best Regards
    Tom

    @MoinTom

    Would you be able provide some more details about the type of devices that are getting this error? (device country, carrier, make, model, OS version, etc.)

    Another possibility is that it is an increase in user's denying write permission. This would result in a similar error.

    Our team is also facing this issue on some of our user's Android platform. Right now we do not have any helpful information as it is working normally on our test devices.

    May I ask what version of IAP plugins are you using?

    @MoinTom,

    Thanks for that extra information.

    Have you tested your app where you denied permission to file system and see if that gives a similar error? I believe there was a change to Android that makes it easier for user's to deny individual app permissions.

    However, Unity IAP should not fall over like this. We are going to make some improvements to how we handle this System.UnauthorizedAccessException. This should give you an error during initialization, so you can handle this situation more gracefully. This change will likely require an engine update, so it will may take a bit of time before it's available.

    In the meantime, you could catch this exception yourself and handle it the same way as an OnInitializedFailed call. Sorry for this inconvenience.

    Thanks for the feedback.

    I just tried to use our app with revoked storage permission and it worked just fine. It could still be possible to be a combination out of OS version an file system accessibility.

    We implemented further instrumentalisation into our app and it will ship next week. So we will be able to tell if the file system is accessible, which the Application.persistentDataPath is and which OS version is used. That should help to nail the problem down.

    ps: Let us know if you have other things in mind we could test out :)

    'OSVersion' => 'Android OS 4.2.2 / API-17 (JDQ39/P3110XXDNE1)',

    I don't see any particular pattern, but maybe you see anything. Good luck!

    Best

    @MoinTom,

    Thanks for providing that information. Unfortunately, we don't really notice a pattern either. Would you be able to PM a link to your app? We have one of the listed devices, so we're gonna try and see if we can reproduce this issue.

    Bump.

    Has there been any progress with this issue? One of my users is experiencing it using a Chromebook.
