Inserting Calendar items in Android ICS

For one of my application we have to insert an event into calendar.

long calID = 3;
long startMillis = 0; 
long endMillis = 0;     
Calendar beginTime = Calendar.getInstance();
beginTime.set(2012, 8, 10, 7, 30);
startMillis = beginTime.getTimeInMillis();
Calendar endTime = Calendar.getInstance();
endTime.set(2012, 8, 10, 8, 45);
endMillis = endTime.getTimeInMillis();
ContentResolver cr = getContentResolver();
ContentValues values = new ContentValues();
values.put(Events.DTSTART, startMillis);
values.put(Events.DTEND, endMillis);
values.put(Events.TITLE, "Jazzercise");
values.put(Events.DESCRIPTION, "Group workout");
values.put(Events.CALENDAR_ID, calID);
values.put(Events.EVENT_TIMEZONE, "America/Los_Angeles");
Uri uri = cr.insert(CalendarContract.Calendars.CONTENT_URI, values);
// get the event ID that is the last element in the Uri
long eventID = Long.parseLong(uri.getLastPathSegment());
Log.d("MainActivity", "addCalendarEvents :: " + "eventID :: "+eventID);

Cursor cursor = cr.query(Events.CONTENT_URI, null, Events.TITLE +"='Jazzercise'", null, null);
Log.d("MainActivity", "addCalendarEvents :: " + "cursor :: "+cursor.getCount());

Provided on However, firstly it gives me a error

 Failed to get type for: content:// (Unknown URL content://

Also the cursor count is zero. When i try to search with the title. Note: I tried using the intents service to add events, however I don't want user discretion while adding the event.

I have tested it on a Galaxy Nexus (4.1) and Nexus S(4.1).

Any help with the correct UI which is to be used with ICS?

I've figured it out. The line:

Failed to get type for: content:// (Unknown URL content://

is a complete red herring (i.e. irrelevant). It's simply some framework code that performs infrastructural work, as seen here.

The problem lies in the documentation - if you're like me, you probably expected long calID = 3; to be some valid Calendar ID. It's not a valid ID, it's a placeholder for the sake of documentation.

What you're doing with the code above, if you're using an empty emulator, is inserting an entry into a non-existent calendar, i.e. nowhere visible.

What you need is to:

  1. Query for and choose an existing calendar. Once again - on the emulator, there is no default calendar.
  2. Use the obtained actual calendar ID to insert the event.

In short - the documentation and debug messages are not idiot-proof enough ;).
