android - AlarmManager not working with time picker -

i have service.. have generate notification @ time taken time picker.. working system.currenttimemillis(), not if take time time picker

here time picker showing on click of textview:

 tv.setonclicklistener(new onclicklistener() {   @override  public void onclick(view v) {   // todo auto-generated method stub   mcurrenttime = calendar.getinstance();   int hour = mcurrenttime.get(calendar.hour_of_day);   int minute = mcurrenttime.get(calendar.minute);   timepickerdialog mtimepicker;   mtimepicker = new timepickerdialog(mainactivity.this, new timepickerdialog.ontimesetlistener() {   @override  public void ontimeset(timepicker timepicker, int selectedhour, int selectedminute) {   timepicker.setis24hourview(true);   //tv.settext( selectedhour + " : " + selectedminute);     mcurrenttime.set(calendar.hour,selectedhour);   mcurrenttime.set(calendar.minute,selectedminute);   mcurrenttime.set(calendar.second,0);   // here getting time timepicker   l= mcurrenttime.gettimeinmillis();   tv.settext(string.valueof(l));   }  }, hour, minute, true);//yes 24 hour tim   mtimepicker.settitle("select time");   mtimepicker.show();    }  }); 

here code of button click, on click starting service:

 intent myintent = new intent(mainactivity.this, myreceiver.class);  int randompin = (int)(math.random()*9000)+1000;  pendingintent = pendingintent.getbroadcast(mainactivity.this, randompin, myintent,pendingintent.flag_one_shot);  alarmmanager alarmmanager = (alarmmanager)getsystemservice(alarm_service);  //here entering time time picker  alarmmanager.set(alarmmanager.rtc, l , pendingintent); 

replace this:

mcurrenttime.set(calendar.hour, selectedhour); 

with this:

mcurrenttime.set(calendar.hour_of_day, selectedhour); 

calendar.hour strictly 12 hours.

as per documentation

field number , set indicating hour of morning or afternoon. hour used 12-hour clock (0 - 11). noon , midnight represented 0, not 12. e.g., @ 10:04:15.250 pm hour 10.
