報警管理器 - 每2小時後觸發

Question

我有一段代碼被調用一次。然而，通知會在每2小時後觸發，因爲我希望它在2天后觸發。我嘗試了所有選項，但仍然無法正常工作

public int setAlarm(){ 
    Calendar Calendar_Object = Calendar.getInstance(); 
    /* 
     Calendar_Object.set(Calendar.MONTH,6); 
     Calendar_Object.set(Calendar.YEAR, 2013); 
     Calendar_Object.set(Calendar.DAY_OF_MONTH, 18);*/ 

      // MyView is my current Activity, and AlarmReceiver is the 
     // BoradCastReceiver 
     Intent myIntent = new Intent(Splash.this, TimeAlarm.class); 

      PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 
        0, myIntent, PendingIntent.FLAG_CANCEL_CURRENT); 

      long wkupTime = Calendar_Object.getTimeInMillis() + 36000; 


     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
//  Log.w("alarm set for " , Calendar_Object.getTime().toString()); 

     /* 
     * The following sets the Alarm in the specific time by getting the long 
     * value of the alarm date time which is in calendar object by calling 
     * the getTimeInMillis(). Since Alarm supports only long value , we're 
     * using this method. 
     */ 

//  alarmManager.setRepeating(AlarmManager.RTC, Calendar_Object.getTimeInMillis(),1000 *24*3600, 
//    pendingIntent); 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, wkupTime , 172800000, pendingIntent); 

     return 0;

public int setAlarm() { 
    Calendar Calendar_Object = Calendar.getInstance(); 

    Intent myIntent = new Intent(Splash.this, TimeAlarm.class); 

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 
        0, myIntent, PendingIntent.FLAG_CANCEL_CURRENT); 

    long wkupTime = Calendar_Object.getTimeInMillis() + 72000; 

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, wkupTime ,7200000, pendingIntent); 

    return 0; 
}
