* 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_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

/**
* Provides convenience methods for in-app billing. You can create one instance of this
* class for your application and use it to process in-app billing operations.
* It provides synchronous (blocking) and asynchronous (non-blocking) methods for
* many common in-app billing operations, as well as automatic signature
* verification.
*
* After instantiating, you must perform setup in order to start using the object.
* To perform setup, call the {@link #startSetup} method and provide a listener;
* that listener will be notified when setup is complete, after which (and not before)
* you may call other methods.
*
* After setup is complete, you will typically want to request an inventory of owned
* items and subscriptions. See {@link #queryInventory}, {@link #queryInventoryAsync}
* and related methods.
*
* When you are done with this object, don't forget to call {@link #dispose}
* to ensure proper cleanup. This object holds a binding to the in-app billing
* service, which will leak unless you dispose of it correctly. If you created
* the object on an Activity's onCreate method, then the recommended
* place to dispose of it is the Activity's onDestroy method.
*
* A note about threading: When using this object from a background thread, you may
* call the blocking versions of methods; when using from a UI thread, call
* only the asynchronous versions and handle the results via callbacks.
* Also, notice that you can only call one asynchronous operation at a time;
* attempting to start a second asynchronous operation while the first one
* has not yet completed will result in an exception being thrown.
