Some services attach some information to the user that can be retrieved and may be necessary to validate receipts.
Currently this is supported on the following services:
You retrieve this data by using the
getUserData() function and listening for the response.
This function will return
false if user data is not supported with the current service.
If it returns
true, then one of two events will be dispatched:
UserDataEvent.GET_SUCCESS: Indicates the user data was successfully retrieved;
UserDataEvent.GET_FAILED: Indicates there was a failure when retrieving the data;
