+ * 2. The purchase flow is synchronous and purchase information is available immediately
+ *    after it completes.
+ * 3. Purchase information of in-app purchases is maintained within the Google Play system
+ *    till the purchase is consumed.
+ * 4. An API to consume a purchase of an inapp item. All purchases of one-time
+ *    in-app items are consumable and thereafter can be purchased again.
+ * 5. An API to get current purchases of the user immediately. This will not contain any
+ *    consumed purchases.
+ *
+ * All calls will give a response code with the following possible values
+ * RESULT_OK = 0 - success
+ * RESULT_USER_CANCELED = 1 - user pressed back or canceled a dialog
+ * RESULT_BILLING_UNAVAILABLE = 3 - this billing API version is not supported for the type requested
+ * RESULT_ITEM_UNAVAILABLE = 4 - requested SKU is not available for purchase
+ * RESULT_DEVELOPER_ERROR = 5 - invalid arguments provided to the API
+ * RESULT_ERROR = 6 - Fatal error during the API action
+ * RESULT_ITEM_ALREADY_OWNED = 7 - Failure to purchase since item is already owned
+ * RESULT_ITEM_NOT_OWNED = 8 - Failure to consume since item is not owned
