Calendar share app

I'm supposed to make an android app which would be able to share a calendar with a group of people (who can log in). they should also be able to add events and to sign up for existing events. i browsed a bit regarding this subject and i found the google calendar option, but i need it inserted in a way in my own app..something like cozi organizer for example..

any thoughts?

thank you!

I think you'd have to program it from scratch yourself, unless google provides the source code for google calendar. There's a google calendar API, but I think its for some language called Apex. I could be wrong.

Look up something in the android docs called: CalendarContract. Could be useful. I can't link to it on the forums, but there's other solutions suggested in stackOverflow for this question:
