我设置了警报以提醒我在android中，当设备打开时它正在工作。但是，当我关闭设备并再次打开时，该提醒警报不起作用。你们能建议我如何解决这个问题吗？

我的代码看起来像这样，

Intent myIntent = new Intent(getApplicationContext(), serviceclass.class);
PendingIntent pendingIntent = PendingIntent.getService(getApplicationContext(),
    CONST+id, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Calendar calender = Calendar.getInstance();
calender.setTimeInMillis(System.currentTimeMillis());
calender.set(Calendar.HOUR_OF_DAY, hours);
calender.set(Calendar.MINUTE, ireminder.getMin());
calender.set(Calendar.SECOND, 0);
calender.set(Calendar.MILLISECOND, 0);  
calender.set(Calendar.DAY_OF_WEEK, day);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,  

calender.getTimeInMillis(), 7 * AlarmManager.INTERVAL_DAY, pendingIntent);
