How to Add recurring events programmatically?

Question

I am developing an application for adding events to calendar. I am using following code to insert recurring event but it force closes the application with an error:

"java.lang.IllegalArgumentException: DTEND and DURATION cannot both be null for an event."

code:

ContentValues event = new ContentValues();
event.put("calendar_id", 1);
event.put("title", "Event Title");
event.put("description", "Event Desc");
event.put("eventLocation", "Event Location");
event.put("dtstart", Long.parseLong("1315432844000"));
event.put("rrule", "FREQ=WEEKLY;WKST=SU;BYDAY=WE");
event.put("allDay", 1);   // 0 for false, 1 for true
event.put("eventStatus", 1);
event.put("hasAlarm", 1); // 0 for false, 1 for true
Uri url = getContentResolver().insert(eventsUri, event);

Answer 1

this is my corrected code..working fine :)

public class mainActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Uri eventsUri;
        if (android.os.Build.VERSION.SDK_INT <= 7) {

            eventsUri = Uri.parse("content://calendar/events");
        } else {

            eventsUri = Uri.parse("content://com.android.calendar/events");
        }

        Calendar cal = Calendar.getInstance();  
        ContentValues event = new ContentValues();
        event.put("calendar_id", 1);
        event.put("title", "Event Title");
        event.put("description", "Event Desc");
        event.put("eventLocation", "Event Location");
        event.put("dtstart",cal.getTimeInMillis());
        event.put("rrule", "FREQ=WEEKLY;WKST=SU;BYDAY=WE");
        event.put("allDay", 1);   // 0 for false, 1 for true
        event.put("eventStatus", 1);
        event.put("hasAlarm", 1); // 0 for false, 1 for true
        event.put("duration","P3600S");
        Uri url = getContentResolver().insert(eventsUri, event);
    }
}

Answer 2

From CalendarContract.Events ...

Insert

When inserting a new event the following fields must be included:

dtstart

dtend if the event is non-recurring

duration if the event is recurring

rrule or rdate if the event is recurring

eventTimezone

a calendar_id

---

So for a recurring event you must have dtstart,duration,rrule/rdate,eventTimezone,calendar_id.

So in your case

remove dtend!
