android: EXDATE format when adding a calendar event

Question

Can someone explain how to use EXDATE when adding event to android calendar? The documentation is pretty unclear about the format in which the EXDATE should be put. I tried many formats, these are some of them:

values.put(Events.EXDATE, "TZID=Europe/London:20130116T080000");
values.put(Events.EXDATE, "20130116T080000Z");
values.put(Events.EXDATE, "20130116T080000");
values.put(Events.EXDATE, "20130116");

but none of them works. Any idea how to make an event not appear on a particular date, if by the RRULE it should appear?

Answer 1

The correct format is:

values.put(Events.EXDATE, "20130116T080000Z");

However you must ensure that it is in UTC time. I was having the same problem starting from PST, so I just had to add 8 hours to get it to work.

Answer 2

In addition to the @kee23's answer, the next variant is valid for multiple EXDATE values:

contentValues.put(CalendarContract.Events.EXDATE, "20130116T080000Z,20130118T080000Z");
