Ok, so I could not get string dates to work, so I had to convert String Dates to Calendar Dates to Unix Time before adding them to the SQLite database and convert them back (Unix Time to Calendar Dates to String) when displaying them. Unix Time allows calculations (order by, sort ascending, between etc) done on the date columns and it is the best method to use after long hours of trial and error. Here is the code I ended up using:

Cursor c = newDB.rawQuery("select ID, Date, Hours from " + tableName + " where Date BETWEEN '" + startDateQueryDate + "' AND '" + endDateQueryDate + "' ORDER BY Date ASC", null);

            if (c != null ) {
                if  (c.moveToFirst()) {
                    do {
                        int tempId = c.getInt(c.getColumnIndex("ID"));
                        long tempUnixTime = c.getLong(c.getColumnIndex("Date"));

                        //convert tempUnixTime to Date
                        java.util.Date startDateDate = new java.util.Date(tempUnixTime);

                        //create SimpleDateFormat formatter
                        SimpleDateFormat formatter1;
                        formatter1 = new SimpleDateFormat("dd/MM/yyyy", Locale.UK);

                        //convert Date to SimpleDateFormat and convert to String
                        String tempStringStartDate = formatter1.format(startDateDate);

                        int tempHours = c.getInt(c.getColumnIndex("Hours"));
                        results.add(+ tempId + "    Date: " + tempStringStartDate + "    Hours: " + tempHours);
                    }while (c.moveToNext());
                }
            }
