I have this piece of code that fire the alarm once by setting a time and date using the TimePicker and the DatePicker in another activity. i want to modify it in a way that whenever i set a time and a date it will fire the alarm everyday at the same time. in other words i want the alarm to be fired dialy

public class M_ReminderManager {

    private Context mContext; 
    private AlarmManager mAlarmManager;

    public M_ReminderManager(Context context) {
        mContext = context; 
        mAlarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
    }

    public void setReminder(Long reminderId, Calendar when) {

        Intent i = new Intent(mContext, Medicines_OnAlarmReceiver.class);
        i.putExtra(RemindersDbAdapter.KEY_ROWID_MEDS, (long)reminderId); 

        PendingIntent pi = PendingIntent.getBroadcast(mContext, 0, i, PendingIntent.FLAG_ONE_SHOT); 
        mAlarmManager.set(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), pi);
      }
}

i have tried using setRepeating function but i dont know how exactly i should set the attributes i used this line instead of the set fuction on the code but it didn't work:

mAlarmManager.setRepeating(AlarmManager.RTC_WAKEUP, when.getTimeInMillis() ,AlarmManager.INTERVAL_DAY , pi);

can someone help me with it?

thanks in advance,
