also creates a global variable [[[googlebilling` of type `GoogleBilling]]] for direct use.
<h3>GoogleBilling Events and Response Codes</h3>
[[[GoogleBilling` class dispatches 5 events: `Event.CHECK_BILLING_SUPPORTED_COMPLETE]]],
[[[Event.REQUEST_PURCHASE_COMPLETE`,`Event.RESTORE_TRANSACTIONS_COMPLETE]]],
[[[Event.CONFIRM_NOTIFICATION_COMPLETE` and `Event.PURCHASE_STATE_CHANGE]]].
[[[Event.*_COMPLETE` events contains a field `event.responseCode]]] which provides status information
and error information about a request. Response code can be one of these values:
<ul>
<li>[[[GoogleBilling.OK]]]: Indicates that the request was sent to the server successfully. When this code is returned</li>
</ul>
in response to a [[[checkBillingSupported]]] function, indicates that billing is supported.
<ul>
<li>[[[GoogleBilling.USER_CANCELED]]]: Indicates that the user pressed the back button on the checkout page instead of buying the item.</li>
<li>[[[GoogleBilling.SERVICE_UNAVAILABLE]]]: Indicates that the network connection is down.</li>
<li>[[[GoogleBilling.BILLING_UNAVAILABLE]]]: Indicates that in-app billing is not available because the API version that</li>
</ul>
you specified is not recognized by the Google Play application or the user is ineligible for in-app billing
(for example, the user resides in a country that prohibits in-app purchases).
<ul>
<li>[[[GoogleBilling.ITEM_UNAVAILABLE]]]: Indicates that Google Play cannot find the requested item in the application's product list.</li>
</ul>
This can happen if the product ID is misspelled in your [[[requestPurchase]]] function or if an item is unpublished in the application's product list.
<ul>
<li>[[[GoogleBilling.DEVELOPER_ERROR]]]: Indicates that an application is trying to make an in-app billing request but the application has not declared the</li>
</ul>
com.android.vending.BILLING permission in its manifest. Can also indicate that an application is not properly signed,
or that you sent a malformed request, such as a request with missing Bundle keys or a request that uses an unrecognized request type.
<ul>
<li>[[[GoogleBilling.ERROR]]]: Indicates an unexpected server error. For example, this error is triggered if you try to purchase an item from yourself, which is not allowed by Google Wallet.</li>
