===============================================

When using UnityIAP, an error is output on that Android version.
I'd like to know if know how to resolve this issue.
Please help me.

 

Please provide more information. Was it working previously? What changed? What version of IAP? Does it work in Mono? Does it work on any Android system? As the error indicates, do you have Descriptions configured for all your IAP products? Just posting an error message is generally not that useful, with no additional context.

 

First of all, thanks for reply. We are using UnityIAP 1.22 When Scripting Backend were Mono, it was compatable to all Android. But when we changed Scripted Backend to IL2CPP, it will error out on Android 4.x and 5.x make it unable to initialise in-app purchase. Currently we are using Mono to temporary fixed this problem. Because of the problem of 64-bit architecture with google play store, after august 1st we need to compile using IL2CPP. There is no problem found after Android Marshmellow though.

 

same here, hope fixed soon!

 

I have the same problem.

I fill shop with products when shop is initialized (and local prices are available) and some players report that their shop is empty. I assume it's because of this issue.

 

I have a similar issue when moving to IL2CPP. I found that if I kill the app manually after closing it (Android keeps it running in the background, so swipe it up / close all etc to kill it), the logon and initialization works properly. Could you confirm this is also the case for you?

Happy to hear I'm not alone on this issue.

This workaround seems to work.

 

My problem occurs on startup.
Few frames after the start "OverflowException: Value is greater than Char.MaxValue or less than Char.MinValue" occurs.
It has nothing to do with closing the app...

 

Is this on Android 4 or 5 (the topic of this thread)? If you search here for your error, I believe you'll find the cause may be due to non-US locale.

 

I'm already using that method.
However, it doesn't seem to have anything to do with the problem that's happening.

 

It's Android 5 related issue (OverflowException).
I don't have my shop translated to another language but I do use localized strings to show prices (for example 29,99zł in Poland).

 

Can users confirm here that the issue being discussed only happens on non-US devices, and only Android 4 and 5?

 

It's been confirmed (on other thread here) that it's (Android 5.0 issue/OverflowException) related to emoji in the title of the game. After removing emoji everything is fine (in my case).

 

Got it, yes the emoji issue has been reported to the IAP team, hopefully it's limited to non-Ascii characters in the title or the other fields. If anyone else is seeing the issue under other circumstances, please reply here.
