Solution 1:

You can separate before API 19 and after API 19. While setting alarm for the first time:

            if (Build.VERSION.SDK_INT >= 19) {
                alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), mondayIntent);
            } else {
                alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                        AlarmManager.INTERVAL_DAY * 7, mondayIntent);
            }

When you catch the alarm:

    if (Build.VERSION.SDK_INT >= 19) {
        rescheduleAlarm();
    }

You must set the alarm with

setexact

again in rescheduleAlarm.

Hope this helps.
