Android :: Droid Access To Google Calendar - Supported Method

How do I find the users available Google Calendars and then create an event in one of those calendars?

Direct access to the Calendar on the handset is for some unknown bizarre reason UNSUPPORTED and not documented and untestable unless you have EVERY single device and ROM. Therefore blind development, cr4p for users and cr4p when you have to blame Google.

Aren't we developing apps to help users with their day-to-day things? Accessing and creating events in a calendar ON THE HANDSET would sem like a logical day-to-day thing to do?

Anyway so I turned to the GDATA API. However the documentation bears no resemblance to anything available for the android SDK. The documented classes stated to be available to be used for Calendar access are not available in the downloadable libraries!?!?!? http://code.google.com/apis/calendar/data/2.0/developers_guide_java.html

So my question, how do I find the users available Google Calendars and then create an event in one of those calendars from an Android app?

Any links posted which say 'see here' please make sure the code is valid for android! :)

(code examples would be great - oh and preferably using the users credentials on the handset to login to the Calendar).
