I am trying to get Amazon IAP working in Xamarin. On first reference to the service, in my code "IAmazonIapV2 iapService = AmazonIapV2Impl.Instance;" I get an exception "initializer for 'Builder' threw an exception. ---> Java.Lang.UnsatisfiedLinkError". The exception text states that it could not find the library "libAmazonIapV2Bridge.so".
I followed the instructions at https://developer.amazon.com/docs/cross-platform-plugins/cpp-xamarin-landing-page.html . I downloaded the plug-in from the link on that page (though I note that right now that link is not working - should there be an updated plug-in file?)
I can reproduce this error by trying to build and run your sample app (from the zip archive AmazonIapV2.xam\AmazonIapV2-1.1\samples\AmazonIapV2). So, seeing as your sample app is showing the same error, I don't think it's an error in my code, or in my project references.
Any help would be appreciated.
