Usually you shouldn't obtain Calendar like you do, there is Calendar.getInstance() method for that:

Calendar cal = Calendar.getInstance();

That gives you a calendar with all fields set to current date, then just:

cal.set(Calendar.HOUR_OF_DAY, 16);
cal.set(Calendar.MINUTE, 25);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);

alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
