title: scheduling notification android
body: <p>Hello I am trying to generate notification at a certain time in Android. I am able to generate the notification, but it generates immediately while I want it to generate at a later time. Can anyone suggest where I went wrong.</p>
  
  <pre><code>calendar.set(Calendar.MONTH, 11);
  calendar.set(Calendar.YEAR, 2016);
  calendar.set(Calendar.DAY_OF_MONTH, 20);
  calendar.set(Calendar.HOUR_OF_DAY, 2);
  calendar.set(Calendar.MINUTE, 58);
  calendar.set(Calendar.SECOND, 0);
  calendar.set(Calendar.AM_PM, Calendar.PM);
  
  long timeinmill = calendar.getTime().getTime() - System.currentTimeMillis();
  Intent myIntent = new Intent(MakeAppointment.this, MyReceiver.class);
  
  PendingIntent pendingIntent = PendingIntent.getBroadcast(MakeAppointment.this, 0, myIntent,0);
  
  AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
  alarmManager.set(AlarmManager.RTC, timeinmill, pendingIntent);
  </code></pre>
