運行特定時間段的後臺服務

Question

我想爲10:00 AM to 8:00 PM運行服務類，我嘗試了AlarmManager但它運行不正常，我該怎麼做？

中的任何一個，請幫助me.`

public void alrammanager(){ 

      Log.d(TAG, "onStartCommand"); 
      Toast.makeText(HomePage.this, "alarm manager start", Toast.LENGTH_LONG).show(); 
      alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
      Intent intent = new Intent(context, MyService.class); 
      alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0); 
      // Set the alarm to start at 8:30 a.m. 

      calendar = Calendar.getInstance(); 
      calendar.setTimeInMillis(System.currentTimeMillis()); 
      calendar.set(Calendar.HOUR_OF_DAY, 10); 
      calendar.set(Calendar.MINUTE, 00); 

      // setRepeating() lets you specify a precise custom interval--in this case, // 20 minutes. 
      int secondsreperts = 30; 
      alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 
      secondsreperts * 1000, alarmIntent); 
}

嘗試這種方式來運行服務。

Calendar calender = Calendar.getInstance(); 
int hourofday = calender.get(Calendar.HOUR_OF_DAY);  

    if (hourofday >10 && hourofday <20){ //between 10am. and 8pm. 

     //start running services 


    } 
    else{ 

     //stop running services 10am. and 8pm. 
    }
