POHow do I do an Android Calendar import of recurring events with syncronizing?
text
Body
copied!<p>For a students app I've implemented a Calendar import feature. An ICS-File will be downloaded from school website which has several events. All events are single events, not recurring events in the ics-file. The import works without problems. But when I want to delete all my imported events I sometimes get a message saying that the records cannot be synchronized. What I was thinking of now is:</p> <ul> <li>Parse ICS-File for all events</li> <li>Try to merge events as recurring events</li> <li>import the recurring events into calendar</li> </ul> <p>But whatever I do is not working. Either events are marked as recurring but monthly and not weekly as intended. Or keep being imported as single events.</p> <p>Here's the last code I've tried. </p> <pre><code> ContentValues event = new ContentValues(); event.put("calendar_id", calId); event.put("title", title); event.put("description", "[HSLU_TAAPP_IMPORTED]"); event.put("eventLocation", location); event.put("eventTimezone", "GMT+1"); long startTime = startDateTime.getTimeInMillis(); startDateTime.add(Calendar.HOUR, 1); long endTime = startDateTime.getTimeInMillis(); event.put("dtstart", startTime); event.put("rrule", "FREQ=WEEKLY"); event.put("dtend", endTime); Uri eventsUri = Uri.parse(getCalendarUriBase()+"events"); Uri insertedUri = _activity.getContentResolver().insert(eventsUri, event); return insertedUri; </code></pre> <p>Can anybody give me an example of how to do it right? Or is there another approach intended to get rid of the "cannot synchronize" message?</p>
