Question

It is possible verifying if an event exists by event_id? I need do something just if an event still exists. It is possible verifying that?

Answer 1

You’ll need to query using the Calendar Provider

First you have to query the calendar provider to get the id of the calendar which you want to search in and then you could construct a count query for the event id you are targeting

Without opening an IDE to check I’d expect that

Uri event = ContentUris.withAppendedId(Events.CONTENT_URI, eventID);
Cursor cursor = managedQuery(event, null, null, null);
If (cursor.getCount() == 1) {
  //the event exists?
}
