question

You can not check subscription status in offline mode. The best way to ensure the subscription is valid is to make a call to getPurchaseUpdatesRequest() when the app starts. This way, you can examine the response and see if the user is still subscribed to the content. You just look for the most recent receipt for the parent SKU, and if the end date on the receipt is null, then the user is still subscribed. You can go through below threads for more information. https://forums.developer.amazon.com/forums/thread.jspa?messageID=3527 https://forums.developer.amazon.com/forums/thread.jspa?messageID=3666 Setting reset equal to false in PurchasingService.getPurchaseUpdates() will give you a paginated response of purchase history since the last call to getPurchaseUpdates(); this is the recommended approach Setting reset equal to true indicates you want a paginated response of the entire purchase history for the customer. Please refer : https://developer.amazon.com/public/apis/earn/in-app-purchasing/docs-v2/implementing-iap-2.0#7.%20Retrieving%20Purchase%20History%20for%20the%20Current%20User

PurchasingService.getPurchaseUpdates(reset);

Thank you very much
