I tryed Amazon Associates API in MyApp.(test mode) In the case of an invalid item, it will be in such a state.(Screenshot_2014-11-19-19-55-52 2.jpg) but ShoppingListener's response is this. IAP Physical SDK/Sandbox Mode: action: com.amazon.device.iap.physical.physical_purchase, message: { "receiveReceipt": true, "packageName": "com.d_jacket.harlequinapp.amazon", "requestId": "3ec9dc27-acec-48cb-9e1d-ecf41b19f527", "productIds": [ "0373238304" ], "sdkVersion": "1.0.64.0", "productType": "PHYSICAL" } IAP Physical SDK/Sandbox Mode: message: { "command": "com.amazon.device.iap.physical.physical_purchase", "requestStatus": "SUCCESSFUL", "marketplace": "US", "requestId": "3ec9dc27-acec-48cb-9e1d-ecf41b19f527", "userId": "l3HL7XppEMhrOGDnur9-ulvqomrSg6qyODKmah76lJU=" } ProductPopoverActivity is not give me error response. I would like to show message like 'invalid item' for user. How to get error of ProductPopoverActivity? and, It's only test mode? What happens in the live mode? please give me answer.
