I used to use https://www.google.com/calendar/dav/ as described here:
http://wiki.meego.com/Migrating_from...ogle_Calendars

However this endpoint does not let to download events after certain date (01/12/2013 or close to it).

I googled this: https://developers.google.com/google...e#new_endpoint

It says "The endpoint https://www.google.com/calendar/dav is deprecated and no longer supported, use it at your own risk. Please make sure you transition to the new endpoint. "

Ok, fine, I do all the steps including Google Cloud services and everything such as:
1. create a "project"
2. enable CalDAV API and "Calendar API"
3. register app - this is tricky - I do not really know how as I do not have the meego calendar app ID so I added something "native" and "web", neither works.
4. tried adding a new CalDAV account on my N9, this is the URL: https://apidata.googleusercontent.co...gmail.com/user
On "sign in", the phone responds with "wrong username or password".

It says I need a Client ID but does not say what I do with it once it is created. Put into the phone? No clue.

So what is wrong with the setup? Has anyone succeded with this? Thanks.
