Listen to android calendar changes. (Sync/Delete/Insert etc..)

Question

I\'ve understand I have to use Content Provider to get all changes, but I also realized starting API14 there is a ready Content Provider

Answer 1

First you need to add this type of receiver to the Manifest:

Then create a simple class which extends broadcast receiver:

public class CatchChangesReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
    // add processing here with some query to content provider
        // in my project I use this selection for getting events:
         final String SELECTION = CalendarContract.Events.CALENDAR_ID + "="
            + calendarId + " AND " + "("
            + CalendarContract.Events.DIRTY + "=" + 1 + " OR "
            + CalendarContract.Events.DELETED + "=" + 1 + ")" + " AND "
            + CalendarContract.Events.DTEND + " > "
            + Calendar.getInstance().getTimeInMillis();
    }
}
