com.distriqt.extension.facebookapi.objects.FacebookAppPurchaseEvent class requires currency as a second argument, but I don't see where I can get it.
com.distriqt.extension.inappbilling.Product has only currencySymbol : it could be $ (USD, Singapore dollar...).
How can I get 3-letters currency code from Billing-ANE to use it in Facebook-ANE?
