How to get Google Calendar on N9 cranking

This Harmattan build supports multiple Mail for Exchange and multiple CalDAV accounts. For Google Calendar:

• Go to Accounts > Add accounts > CalDAV
• Username should be your full Google Calendar username (e.g. jbloggs@gmail.com) and password.
• The URL is:
  • For your primary calendar: https://www.google.com/calendar/dav/
  • For other calendars: https://www.google.com/calendar/dav/uuid@group.calendar.google.com/
  • For some users, the primary calendar will only work with, supposing your e-mail is jbloggs@gmail.com: https://www.google.com/calendar/dav/jbloggs@gmail.com/

The uuid can be found on the calendar settings page within Google Calendar, and is a long string of characters & numbers.
The trailing slashes are crucial for Google.

• The primary calendar claimed to sync, but no events showed up. So I deleted the CalDAV entry for my primary calendar and set up Mail for Exchange:
  • Username is your full Google Calendar username and password
  • Server: m.google.com
• I synced my primary calendar using the syntax of the second URL (with my Google login email instead of uuid@google) and it worked great. YMMV.

• Note: for me the sync button only worked once you go back out after creating the entry, and then back into it again.
