/**
* 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.
*
* <p>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.
*
* <p>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.
*
* <p>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.
*
* <p>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.
*
