Hope it helps :)

Get Event Id :

private int ListSelectedCalendars(String eventtitle) {


    Uri eventUri;
    if (android.os.Build.VERSION.SDK_INT <= 7) {
        // the old way

        eventUri = Uri.parse("content://calendar/events");
    } else {
        // the new way

        eventUri = Uri.parse("content://com.android.calendar/events");
    }

    int result = 0;
    String projection[] = { "_id", "title" };
    Cursor cursor = getContentResolver().query(eventUri, null, null, null,
            null);

    if (cursor.moveToFirst()) {

        String calName;
        String calID;

        int nameCol = cursor.getColumnIndex(projection[1]);
        int idCol = cursor.getColumnIndex(projection[0]);
        do {
            calName = cursor.getString(nameCol);
            calID = cursor.getString(idCol);

             if (calName != null && calName.contains(eventtitle)) {
            result = Integer.parseInt(calID);
            }

        } while (cursor.moveToNext());
        cursor.close();
    }

    return result;

}

Update Event :

@SuppressLint("InlinedApi")
private int UpdateCalendarEntry(int entryID) {
    int iNumRowsUpdated = 0;

    Uri eventUri;
    if (android.os.Build.VERSION.SDK_INT <= 7) {
        // the old way

        eventUri = Uri.parse("content://calendar/events");
    } else {
        // the new way

        eventUri = Uri.parse("content://com.android.calendar/events");
    }

    ContentValues values = new ContentValues();
    values.put(Events.TITLE, "test");
    values.put(Events.EVENT_LOCATION, "Chennai");

    Uri updateUri = ContentUris.withAppendedId(eventUri, entryID);
    iNumRowsUpdated = getContentResolver().update(updateUri, values, null,
            null);

    return iNumRowsUpdated;
}

Delete Event :

    private int DeleteCalendarEntry(int entryID) {
    int iNumRowsDeleted = 0;

    Uri eventUri = ContentUris
            .withAppendedId(getCalendarUriBase(), entryID);
    iNumRowsDeleted = getContentResolver().delete(eventUri, null, null);

    return iNumRowsDeleted;
}

private Uri getCalendarUriBase() {
    Uri eventUri;
    if (android.os.Build.VERSION.SDK_INT <= 7) {
        // the old way

        eventUri = Uri.parse("content://calendar/events");
    } else {
        // the new way

        eventUri = Uri.parse("content://com.android.calendar/events");
    }

    return eventUri;
}
