/**
 * 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. *

* 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) * @author sisbell (Modified original class for Skubit support) */ public class SkubitIabHelper implements AppstoreInAppBillingService { /** * TODO: move to Options? * Skubit doesn't support getSkuDetails for more than 30 SKUs at once */ public static final int QUERY_SKU_DETAILS_BATCH_SIZE = 30; // Is setup done? protected boolean mSetupDone = false; // Are subscriptions supported? protected boolean mSubscriptionsSupported = false; // Is an asynchronous operation in progress? // (only one at a time can be in progress) protected boolean mAsyncInProgress = false; // (for logging/debugging) // if mAsyncInProgress == true, what asynchronous operation is in progress? protected String mAsyncOperation = ""; // Context we were passed during initialization protected Context mContext; // Connection to the service @Nullable protected IBillingService mService; @Nullable protected ServiceConnection mServiceConn; /** * for debug purposes */ protected ComponentName mComponentName; // The request code used to launch purchase flow protected int mRequestCode; // The item type of the current purchase flow protected String mPurchasingItemType; // Public key for verifying signature, in base64 encoding @Nullable protected String mSignatureBase64 = null; /** * TODO: IabHelper for Skubit and OpenStore must not be same */ private Appstore mAppstore; /** * Creates an instance.
