android - How can i delete an Event from Google Calendar programatically? -


helo,

i want delete calendar event.

with code https://developer.android.com/guide/topics/providers/calendar-provider.html#delete-event 

    contentresolver cr = this.c.getcontentresolver();     contentvalues values = new contentvalues();     uri deleteuri = null;     deleteuri = contenturis.withappendedid(calendarcontract.events.content_uri, eventid);     int rows = this.c.getcontentresolver().delete(deleteuri, null, null);     system.out.println("eventid: " + eventid + " rows deleted: " + rows);

it doesn't work.

why issue?

with line 

    system.out.println("eventid: " + eventid + " rows deleted: " + rows);

i get

07-28 17:33:45.984 30895-30895/de.ubik.kalender i/system.out: eventid: 5 rows deleted: 0

i guess, event id right. what's problem? don't know.
