* InAppBillingService is the service that provides in-app billing version 3 and beyond.

* 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_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
