I am seeking to implement AmazonIapV2 IAPs for my project. I have made the changes to the manifest as set out in the documentation and added the ANE to the project fine. AmazonIapV2.isSupported() comes back as true. However the ANE does not appear to include the PurchasingListener referred to in the documentation so I can't register it as referred to in the documentation here https://developer.amazon.com/public/apis/earn/in-app-purchasing/docs-v2/implementing-iap. The methods are present but there does not seem to be the ability to register and create an instance.
Note that documentation appears to relate to a Java version rather than as3 but, apart from some syntax I was expecting it to be similar.
A worked example of how to implement IAPs in AS3 would be great.
