Android Calendar Provider does not return latest data

问题

I am using the following code:

String selection = "((dtstart >= " + now
        + ") AND (dtend <= " + endTime.getTimeInMillis() + "))";
Cursor cursor = context.getContentResolver()
        .query(Uri.*parse*("content://com.android.calendar/events"),
                *PROJECTION*, selection,null, null);

And I notice that once I add/remove an Event to Google Calendar app on the device and run the above code immediately, occasionally I do not get the latest dataset from the Cursor. I have to manually refresh the Google Calendar app to get the latest data.

Am I missing something? Can I use some other APIs?

Thanks!

To get latest data after adding event to calendar you can listen calendar for event changes
