                                d[i] = d[i + 1];    
                                d[i + 1] = temp;        
                            }
                        }
                    }

Seems like you are using wrong date format.

In order to sort by DATETIME in SQLite, you need to use correct date format as below:

DateFormat dateFormatISO8601 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
