I see one other question about this but there wasn't really any resolution. I have integrated the IAP v2.0 Unity plugin based on this guide: https://developer.amazon.com/public/apis/earn/in-app-purchasing/docs-v2/using-the-iap-plugin-for-unity
I have also updated the AndroidManifest file as described here: https://developer.amazon.com/public/solutions/platforms/cross-platform/unity/docs/adding-a-plugin-to-your-unity-project
I deployed an APK to a Kindle Fire and it runs but I don't get any responses when I call
IAmazonIapV2 iapService = AmazonIapV2Impl.Instance; iapService.GetUserData();
Or any of the other methods like GetProductData or GetPurchaseUpdates. In LogCat, I do see that the methods are invoking something since I see messages like:
AmazonIapV2UnityAndroid: Successfully called native code in 18 ms
Any help would be appreciated! Thanks.
