Add recurring event to Android calendar with frequency and recurring end date

Question

What I used as recommendations:

http://developer.android.com/guide/topics/providers/calendar-provider.html#events

http://developer.android.com/reference/android/provider/CalendarContract.Events.html

http://tools.ietf.org/html/rfc5545#section-3.8.5.3 (for RRULE)

What I have about the event:

• the date of the beginning
• recurring end date
• frequency (every day / week / month / year)

What do I need, given:

• start date: 06/11/2014 13:00
• recurring frequency: daily
• repeating end date: 06/14/2014 10:00

I need to add an Android event that lasts 1 hour every day from 11.06 to 14.06 (not inclusive - because the start hour is higher than the repeating end hour):

• 11.06 13: 00-14: 00
• 12.06 13: 00-14: 00
• 13.06 13: 00-14: 00

...
ContentValues values = new ContentValues();
values.put(Events.DTSTART, event.getDate().getTime());
if (!event.isRecurring()) { // ignore
    values.put(Events.DTEND, event.getEndDate().getTime());
    values.putNull(Events.DURATION);
    values.putNull(Events.RRULE);
    values.putNull(Events.RDATE);
} else {
    values.putNull(Events.DTEND);
    values.put(Events.DURATION, "PT1H"); // set event duration as 1H - this is ok hardcoded
    values.put(Events.RDATE, event.getRecurringEnd().getTime()); // when the event should stop recurring
    values.put(Events.RRULE,
            Utils.getRRuleForRecurring(event.getRecurring()) + ";UNTIL=" + event.getRecurringEnd().getTime());  
}
values.put(Events.TITLE, event.getName());
values.put(Events.DESCRIPTION, event.getDescription() == null ? ""
        : event.getDescription());
values.put(Events.CALENDAR_ID, calendarId);
values.put(Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
...

RRule:

public static String getRRuleForRecurring(String recurring) {
    recurring = recurring.toLowerCase();
    if (recurring.equals("every day")) {
        return "FREQ=DAILY";
    }
    if (recurring.equals("every month")) {
        return "FREQ=MONTHLY";
    }
    if (recurring.equals("every week")) {
        return "FREQ=WEEKLY";           
    }
    if (recurring.equals("every year")) {
        return "FREQ=YEARLY";
    }

    return "FREQ=DAILY";
}
