+/**
+ * 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. It is invalid to
+ * dispose the object while an asynchronous operation is in progress. You can
+ * call {@link #disposeWhenFinished()} to ensure that any in-progress operation
+ * completes before the object is disposed.
+ *
+ * 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.
