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. * * @author Bruno Oliveira (Google) * */ public class IabHelper implements IIabHelper { @InjectLogger private static Logger logger; // Is setup done? boolean mSetupDone = false; // Has this object been disposed of?
