鬧鐘管理器設置重複沒有等到時間關閉

Question

我正在設置此鬧鐘在X處關閉，當前時間爲Y，並且在時間發送鬧鐘Y沒有等到時間X關閉...可以任何人都會告訴我爲什麼不等到正確的時間才能離開？樣品的logcat：

這是改變報警代碼。它目前的工作，並根據我的知識工作正常。

public void SetAlarm(Context context) 
{ 
    mPreferences = PreferenceManager.getDefaultSharedPreferences(context); 
    reminder = mPreferences.getBoolean("frequency", false); 
    time_selected = mPreferences.getString("alarm_time", ""); 


    Time now = new Time(); 
    now.setToNow(); 

    if (reminder) { 
     Log.i("PROJECTCARUSO","Setting Alarm"); 

     AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
     Intent i = new Intent(context, Alarm.class); 
     PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); 

     // time selected from settings information 
     String[] separated = time_selected.split(":"); 


     //Create an offset from the current time in which the alarm will go off. 
     Calendar cal = Calendar.getInstance(); 
     cal.setTimeInMillis(System.currentTimeMillis()); 
     cal.set(Calendar.HOUR_OF_DAY, (int) Long.parseLong(separated[0])); 
     cal.set(Calendar.MINUTE, (int) Long.parseLong(separated[1])); 

     Log.i("PROJECTCARUSO", "Time set to go off: " + cal.getTimeInMillis()); 
     am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 86400000, pi); // Millisec * Second * Minute 
    } else { 
     CancelAlarm(context); 
    } 
}

只提「triggerAtMillis」的說法的概念：

你必須添加要等待到當前時間的時間量。

例如，下面的行第一觸發接收器類在十秒鐘後，並不斷重複它每20秒：

am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + 10000, 20000, pi);
