AlarmManager not scheduling task at given time

Question

I am trying to do some task at some specific time inserted by user. I have two classes.

1. AddTiminigs
2. TimeReceiver

In OnCreate of "AddTimings, I m doing something like this:

manager = (AlarmManager)getActivity().getSystemService(getActivity().ALARM_SERVICE);

Intent alarmIntent_on = new Intent(getActivity(), MuteMeReceiver.class);
alarmIntent_on.putExtra("id", MUTE_ON);
pendingIntent_on = PendingIntent.getBroadcast(getActivity().getApplicationContext(), MUTE_ON, alarmIntent_on, 0);

Then, on some action, i m doing this :

manager.setRepeating(AlarmManager.RTC_WAKEUP,  startTimeInMilis,
                    AlarmManager.INTERVAL_DAY, pendingIntent_on);

And Here is my "TimeReceiver":

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

    muteStatus = incomingPendingIntent.getIntExtra("id", AddTimeFragment.MUTE_ON);

    if(muteStatus == AddTimeFragment.MUTE_ON){

        Toast.makeText(context, "GENERAL", Toast.LENGTH_SHORT).show();

    }

}

The Problem is that very after adding the time, it doesn't bother what the start time is, it just goes to receiver and not doing the task on the time i mentioned. The timing is in miliseconds, which is ok.

EDIT: I am using TimePicker for starttime. Here is my code:

        hour = calendar.get(Calendar.HOUR_OF_DAY);
        minute = calendar.get(Calendar.MINUTE);

  private TimePickerDialog.OnTimeSetListener listenerForStartTime =new TimePickerDialog.OnTimeSetListener() {
        public void onTimeSet(TimePicker view, int selectedHour, int selectedMinute) {

            if(selectedHour < 12) {
                am_pm = "AM";
            } else {
                am_pm = "PM";
            }

            startTimeInMilis = (selectedMinute * 60 + selectedHour * 60 * 60) * 1000;

        }
    };

Answer 1

Change your listenerForStartTime code as below. You are giving start time wrongly. you should not give remaining time. you should give exact time.

private TimePickerDialog.OnTimeSetListener listenerForStartTime =new TimePickerDialog.OnTimeSetListener() {
    public void onTimeSet(TimePicker view, int selectedHour, int selectedMinute) {

        if(selectedHour < 12) {
            am_pm = "AM";
        } else {
            am_pm = "PM";
        }
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR_OF_DAY, selectedHour);
        calendar.set(Calendar.MINUTE, selectedMinute);
        startTimeInMilis = calendar.getTimeInMillis();
    }
};
