/** |
41 |
* Provides convenience methods for in-app billing. You can create one instance of this |
42 |
* class for your application and use it to process in-app billing operations. |
43 |
* It provides synchronous (blocking) and asynchronous (non-blocking) methods for |
44 |
* many common in-app billing operations, as well as automatic signature |
45 |
* verification. |
46 |
* |
47 |
* After instantiating, you must perform setup in order to start using the object. |
48 |
* To perform setup, call the {@link #startSetup} method and provide a listener; |
49 |
* that listener will be notified when setup is complete, after which (and not before) |
50 |
* you may call other methods. |
51 |
* |
52 |
* After setup is complete, you will typically want to request an inventory of owned |
53 |
* items and subscriptions. See {@link #queryInventory}, {@link #queryInventoryAsync} |
54 |
* and related methods. |
55 |
* |
56 |
* When you are done with this object, don't forget to call {@link #dispose} |
57 |
* to ensure proper cleanup. This object holds a binding to the in-app billing |
58 |
* service, which will leak unless you dispose of it correctly. If you created |
59 |
* the object on an Activity's onCreate method, then the recommended |
60 |
* place to dispose of it is the Activity's onDestroy method. |
61 |
* |
62 |
* A note about threading: When using this object from a background thread, you may |
63 |
* call the blocking versions of methods; when using from a UI thread, call |
64 |
* only the asynchronous versions and handle the results via callbacks. |
65 |
* Also, notice that you can only call one asynchronous operation at a time; |
66 |
* attempting to start a second asynchronous operation while the first one |
67 |
* has not yet completed will result in an exception being thrown. |
