Any answer will be helpfull for me to proceed.

Replace this code :

ContentResolver contentResolver = context.getContentResolver();

        Calendar c_start = Calendar.getInstance();
        c_start.set(2014,2,4,0,0); //Note that months start from 0 (January)   
        Calendar c_end = Calendar.getInstance();
        c_end.set(2013,2,11,0,0); //Note that months start from 0 (January)


        String selection = "((dtstart >= "+c_start.getTimeInMillis()+") AND (dtend <= "+c_end.getTimeInMillis()+"))";

        String[] selectionArgs = new String[] {startString, endString};
        cursor = contentResolver.query(Uri.parse("content://com.android.calendar/events"), 
                (new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation"})
                ,null,selectionArgs,selection);

With this:

Uri l_eventUri;
    Calendar calendar = Calendar.getInstance();
    if (Build.VERSION.SDK_INT >= 8) {
        l_eventUri = Uri.parse("content://com.android.calendar/events");
    } else {
        l_eventUri = Uri.parse("content://calendar/events");
    }
    ContentResolver contentResolver = context.getContentResolver();

    String dtstart = "dtstart";
    String dtend = "dtend";

    String[] l_projection = new String[] { "title", "dtstart", "dtend" };

    SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yy");
    // Date dateCC = formatter.parse("04/27/2013");
    Date dateCC = formatter.parse("11/13/2013");
    calendar.setTime(dateCC);

    long after = calendar.getTimeInMillis();

    SimpleDateFormat formatterr = new SimpleDateFormat("MM/dd/yy hh:mm:ss");

    Calendar endOfDay = Calendar.getInstance();
    Date dateCCC = formatterr.parse("17/13/2013 23:59:59");
    // Date dateCCC = formatterr.parse(startDate + " 23:59:59");
    endOfDay.setTime(dateCCC);

    cursor= contentResolver.query(l_eventUri, new String[] { "title",
            "dtstart", "dtend" }, "(" + dtstart + ">" + after + " and "
            + dtend + "<" + endOfDay.getTimeInMillis() + ")", null,
            "dtstart ASC");
