- * InAppBillingService is the service that provides in-app billing version 3 and beyond.
- * This service provides the following features:
- * 1. Provides a new API to get details of in-app items published for the app including
- *    price, type, title and description.
- * 2. The purchase flow is synchronous and purchase information is available immediately
- *    after it completes.
- * 3. Purchase information of in-app purchases is maintained within the Google Play system
- *    till the purchase is consumed.
- * 4. An API to consume a purchase of an inapp item. All purchases of one-time
- *    in-app items are consumable and thereafter can be purchased again.
- * 5. An API to get current purchases of the user immediately. This will not contain any
- *    consumed purchases.
- *
- * All calls will give a response code with the following possible values
- * RESULT_OK = 0 - success
- * RESULT_USER_CANCELED = 1 - User pressed back or canceled a dialog
- * RESULT_SERVICE_UNAVAILABLE = 2 - The network connection is down
- * RESULT_BILLING_UNAVAILABLE = 3 - This billing API version is not supported for the type requested
- * RESULT_ITEM_UNAVAILABLE = 4 - Requested SKU is not available for purchase
- * RESULT_DEVELOPER_ERROR = 5 - Invalid arguments provided to the API
- * RESULT_ERROR = 6 - Fatal error during the API action
- * RESULT_ITEM_ALREADY_OWNED = 7 - Failure to purchase since item is already owned
- * RESULT_ITEM_NOT_OWNED = 8 - Failure to consume since item is not owned
