title: AlarmManager not fires on time in Android Lollipop
body: <p>i'm using this code to set Alarm in Android KitKat and lollipop:</p>
  
  <pre><code>    AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
      Intent i = new Intent(AlarmService.this, Reciver.class);
      PendingIntent pi = PendingIntent.getBroadcast(AlarmService.this, 1201, i, PendingIntent.FLAG_UPDATE_CURRENT);
      Calendar c = Calendar.getInstance();
      c.set(Calendar.HOUR_OF_DAY, 9);
      c.set(Calendar.MINUTE, 0);
      c.set(Calendar.SECOND, 0);
      am.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pi);
  </code></pre>
  
  <p>this code is works good on Android KitKat but on Android Lollipop its fires With 10 or 5 minutes delayed.</p>
