/**
* 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.
