How to add calendar events in Android

Question

how do I programmatically add an event to the user s calendar    Which calendar      Is there a common API they all share    No  no more than there is a  common API they all share  for Windows calendar apps  There are some common data formats  e g   iCalendar  and Internet protocols  e g   CalDAV   but no common API  Some calendar apps don t even offer an API   If there are specific calendar applications you wish to integrate with  contact their developers and determine if they offer an API  So  for example  the Calendar application from the Android open source project  that Mayra cites  offers no documented and supported APIs  Google has even explicitly told developers to not use the techniques outlined in the tutorial Mayra cites   Another option is for you to add events to the Internet calendar in question  For example  the best way to add events to the Calendar application from the Android open source project is to add the event to the user s Google Calendar via the appropriate GData APIs     UPDATE  Android 4 0  API Level 14  added a CalendarContract ContentProvider
