Question

我正在开发一个Android应用程序，我在其中设置多个alarm.Alarm可以设置为一次，每天和每周。我将闹钟hrs，mins和am / pm设置为

     Calendar alarmCalendar = Calendar.getInstance();
     alarmCalendar.set(Calendar.HOUR, 10);
     alarmCalendar.set(Calendar.MINUTE, 45);
     alarmCalendar.set(Calendar.SECOND, 0);
     alarmCalendar.set(Calendar.AM_PM, 0);

    Long alarmTime = alarmCalendar.getTimeInMillis();

并以毫秒为单位比较时间是否过去

            if(alarmType.equalsIgnoreCase("daily"))
            {
                if (currenttime >= alarmTime)
                {
                    alarmTime+=86400000; // 1day in milliseconds
                }

                Intent intent = new Intent(Alarm.this, Reciever.class);
                intent.putExtra("keyValue", key);
                PendingIntent pi = PendingIntent.getBroadcast(Alarm.this, key, intent, PendingIntent.FLAG_UPDATE_CURRENT);
                am.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, AlarmManager.INTERVAL_DAY, pi); 
            }

            else if(alarmType.equalsIgnoreCase("weekly"))
            {
                if (currenttime >= alarmTime)
                {
                    alarmTime+=604800000;//1 week in milliseconds
                }

                Intent intent = new Intent(Alarm.this, Reciever.class);
                intent.putExtra("keyValue", key);
                PendingIntent pi = PendingIntent.getBroadcast(Alarm.this, key, intent, PendingIntent.FLAG_UPDATE_CURRENT);
                am.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, 604800000 , pi); 

            }

它在某些手机上正常工作，并且在闹钟时间结束后，每天和每周分别适当地设置为每天和每周。但问题是，在少数手机和平板电脑上，警报不会被触发。任何人都可以说这个问题。请帮忙！谢谢！
