Notification started from AlarmManager keeps repeating again

When I set a Notification on a particular date and time chosen from a DatePicker and a TimePicker, The notification appears on the correct time but after I cancel it, it reappears after some time.
I have tried setAutoCancel(true) and Notification.FLAG_AUTO_CANCEL but they don't seem to work.

here is the code-snippet where I'm setting alarm 

 if(item.getTitle().equals("Add Reminder"))
    {
        Log.d("REMINDER", "Show Time Picker Entered from Decided Case");
        final Dialog dialog = new Dialog(this);

        dialog.setContentView(R.layout.date_time_layout);

        dialog.setTitle("Choose Date and Time");

        dialog.show();
        Button ok = (Button) dialog.findViewById(R.id.alarm_set);
        ok.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                DatePicker dp = (DatePicker) dialog.findViewById(R.id.datePicker1);
                TimePicker tp = (TimePicker)dialog.findViewById(R.id.timePicker1);

                Calendar cal = Calendar.getInstance();       //for using this you need to import java.util.Calendar;

                // add minutes to the calendar object
                cal.set(Calendar.MONTH, dp.getMonth());
                cal.set(Calendar.YEAR, dp.getYear());               
                cal.set(Calendar.DAY_OF_MONTH, dp.getDayOfMonth());
                cal.set(Calendar.HOUR_OF_DAY, tp.getCurrentHour());
                cal.set(Calendar.MINUTE, tp.getCurrentMinute());
                //cal.add(Calendar.MINUTE, 1);
                 //cal.setTimeInMillis(System.currentTimeMillis());
                // cal.add(Calendar.SECOND, 10);
                Intent alarmintent = new Intent(getApplicationContext(), AlarmReceiver.class);


                PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), 0,
                alarmintent,0);
                int HELLO_ID=1;
                // Get the AlarmManager service
                HELLO_ID++;
                AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
                am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
                Log.d("Alarm Set","day = "+dp.getDayOfMonth()+" month = "+(dp.getMonth()+1)+" year = "+dp.getYear()+" hours "+tp.getCurrentHour()+" minutes = "+tp.getCurrentMinute());
                dialog.dismiss();

            }
        });
    }

AlarmReciever.java 

public class AlarmReceiver extends BroadcastReceiver {



    @Override
public void onReceive(Context context, Intent intent) {

    // When our Alaram time is triggered , this method will be excuted (onReceive)

Ideally you should not use service to just send notification , I think it would be better if you write some Util function and move the code of service onStart to Util method.

If you requirement needs service only then I suggest you to use IntentServive

It is probably because of the alarm. Notification itself cannot add it one more time if you call setAutoCancel(true).

You can try

a.cancel(sender) in onReceive of AlarmReceiver of yours. You will have to recreate that sender object to cancel it.
