警报员多次射击

Question

我之前已经问过这个，天知道我已经尝试了所有建议。我想在每天给定的时间每天执行一次服务。我能够设置闹钟和广播。但由于某些原因，当警报被解雇时，比如说13点30分，它会在几个不规则的时间间隔内被发射。唯一正常工作的是首先在正确的时间点火，然后它会在一整天都开火，这让我发疯。请帮忙。

    PendingIntent reviewsPendingIntent = PendingIntent.getBroadcast(this,0,new Intent(this,ReviewReceiver.class),PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarmManager = (AlarmManager)(this.getSystemService(Context.ALARM_SERVICE));
    Calendar cur_cal = new GregorianCalendar();
    cur_cal.setTimeInMillis(System.currentTimeMillis());

    Random random = new Random();
    int low = 7;
    int high = 22;
    int hour = random.nextInt(high - low) + low;
    int minute = random.nextInt(60 - 10) + 10;
    Calendar cal = new GregorianCalendar();
    cal.set(Calendar.HOUR_OF_DAY, 13);
    cal.set(Calendar.MINUTE,15);
    cal.set(Calendar.SECOND,5);
    cal.set(Calendar.MILLISECOND,0);
    if(cal.getTimeInMillis() >= System.currentTimeMillis() ) {
        Log.i(TAG,"Set today");
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, reviewsPendingIntent);
    }else{
        Log.i(TAG,"Set tomorrow");
        cal.set(Calendar.DATE,1);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, reviewsPendingIntent);
    }

  

N.B。当我得到这个时，我计划使用随机整数设置我的闹钟   工作正常。
