The calendar app on Android can merge multiple separate calendars: local phone calendar, Google calendars, etc.

How can I add a new such calendar to the Android phon

Answer 1

I just managed to add a Calendar using the new API from ICS. Stefan's answer helped, but to be able to write to all columns, you have to do the operation as a sync adapter. You can do this from a normal app using CalendarContract.ACCOUNT_TYPE_LOCAL. The following code should work on ICS. Maybe some column values are not right. Check out the documentation of CalendarContract.Calendars. Unfortunately I cannot help you for older Android versions, but CalendarContract is only used for some constant string values. Maybe these also work on older versions.

Uri calUri = CalendarContract.Calendars.CONTENT_URI;
ContentValues cv = new ContentValues();
cv.put(CalendarContract.Calendars.ACCOUNT_NAME, yourAccountName);
cv.put(CalendarContract.Calendars.ACCOUNT_TYPE, CalendarContract.ACCOUNT_TYPE_LOCAL);
cv.put(CalendarContract.Calendars.NAME, yourInternalName);
cv.put(CalendarContract.Calendars.CALENDAR_DISPLAY_NAME, yourDisplayName);
cv.put(CalendarContract.Calendars.CALENDAR_COLOR, yourColor);
cv.put(CalendarContract.Calendars.CALENDAR_ACCESS_LEVEL, CalendarContract.Calendars.CAL_ACCESS_OWNER);
cv.put(CalendarContract.Calendars.OWNER_ACCOUNT, true);
cv.put(CalendarContract.Calendars.VISIBLE, 1);
cv.put(CalendarContract.Calendars.SYNC_EVENTS, 1);

calUri = calUri.buildUpon()
    .appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true")
    .appendQueryParameter(CalendarContract.Calendars.ACCOUNT_NAME, ACCOUNT_NAME)
    .appendQueryParameter(CalendarContract.Calendars.ACCOUNT_TYPE, CalendarContract.ACCOUNT_TYPE_LOCAL)
    .build();
Uri result = this.getContentResolver().insert(calUri, cv);
