I was on ics before but i'm back on gb now, in ics if want your calendar sync with gmail calendar, you need to add your gmail account using exchange app(or server

) i guess it is built in with ics, it takes me a few try and error before finding this out. after adding gmail account in exchange, your calendar will sync flawlessly..cheers

Bro thanks for your tips. FYI, i have try several times to setup exchange with google. and stupidest is i always put gmail server as m.gmail.com which is wrong!
Simply put, if you ever get the issue in Accounts & Sync for a gMail account where it prompts you for the Domain\Username, Password, and Server, here's what you enter:
Domain\Username: \(user)@gmail.com
Password: (password)
Server: m.google.com
and yes, using exchange can solve calendar sync.
p/s actually i try to reinstall gapps for calendar only, try so many time, but it seems the "sync" setting came out if using google but it's not work and my calendar forced closed.
thanks anyway
