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 { // Is debug logging enabled? boolean mDebugLog = false; String mDebugTag = "IabHelper"; // Is setup done? boolean mSetupDone = false; // Are subscriptions supported? boolean mSubscriptionsSupported = false; // Is an asynchronous operation in progress? // (only one at a time can be in progress) boolean mAsyncInProgress = false; // (for logging/debugging) // if mAsyncInProgress == true, what asynchronous operation is in progress?
