question

Please notify the developers so they can fix these problems.

It would be really helpful if someone from Amazon could answer this.

AppyNation, Based on our investigation, the InvalidOperationException exception is thrown because you are attempting in your code to modify the list of event handlers inside an event handler itself. For instance, when your event handler for the adLoaded event might be trying to deregister itself as an event handler. This is our best guess based on the limited info you provided: stack trace and our investigations in trying to reproduce the issue. A few questions: If you still need to register/unregister event handlers, can you not do it inside an event handler itself? If you try that, can you please confirm whether this solution works for you? If not, can you please provide the Unity version and Xcode version you are using to build as well as the iOS device you use for testing? Can you also please share some sample code illustrating how you are using the plugin? Thanks!

Yes, you are correct, I am removing listeners from a listener. This is not normally a problem, I do this type of thing quite a bit with async ops. I like to have a method that has an action that executes when the op is complete, like this: bool LoadAndShowBanner(System.Action onDone) { Action cleanUp = null; AdLoadedDelegate loaded = (Ad obj)=>{ if(obj.AdType==AdType.FLOATING) { cleanUp(); onDone(true); } }; AdFailedToLoadDelegate failed = (Ad obj)=>{ if(obj.AdType==AdType.FLOATING) { cleanUp(); onDone(false); } }; cleanUp = ()=>{ mobileAds.RemoveAdLoadedListener(loaded); mobileAds.RemoveAdFailedToLoadListener(failed); }; mobileAds.AddAdLoadedListener(loaded); mobileAds.AddAdFailedToLoadListener(failed); var placement = new Placement(); placement.Dock = Dock.TOP; placement.HorizontalAlign = HorizontalAlign.CENTER; placement.AdFit = AdFit.FIT_AD_SIZE; banner = mobileAds.CreateFloatingBannerAd(placement); mobileAds.LoadAndShowFloatingBannerAd(banner); return true; }

And also please make sure to remove the 10 warnings from the next release. Message was edited by: AppyNation Ltd.

Thanks AppyNation Ltd. -- we have captured your feedback and will work to implement a fix / remove those warnings. As for your last message about the warnings, if you are referring to the warnings you mentioned in another thread, I have replied to it here: https://forums.developer.amazon.com/forums/message.jspa?messageID=27947#27947

No, I'm talking about warnings in Unity when your code compiles.

Yes, that too, we are tracking it to remove warnings for not using the logger variable. Thanks!
