- * 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.
