how to delete or edit event from G-calendar from my android app?

I'm fetching a list of Google calendar events.

which event identifier can I get to be able to delete and edit specific event

Here is my fetching code:

private void fetchEvents() {
        String[] selection = new String[] { "calendar_id", "title", "description",
                "dtstart", "dtend", "eventLocation" };

        String projection = "description LIKE ?";
        String[] selecionArgs = new String[]{"%/images/%"};
        String orderby = "dtstart ASC";

        Cursor cursor = getContentResolver()
                .query(
                        Uri.parse("content://com.android.calendar/events"),
                        selection, projection,
                        selecionArgs, orderby);
        cursor.moveToFirst();
        // fetching calendars name
        String CNames[] = new String[cursor.getCount()];

        for (int i = 0; i < CNames.length; i++) {
            nameOfEvent.add(cursor.getString(1));
            cursor.moveToNext();
        }
    }

here I want to delete an event (by the way which type should I use for editing?)

    private void deleteCalendarEvent_intent() {
        Intent intent = new Intent(Intent.ACTION_DELETE)

//?
        startActivity(intent);
    }
