onLocationUpdate不是在服務調用

Question

我正在開發一個應用程序需要檢索用戶位置的時間段。我在活動中使用了LocationListener接口，並且它運行良好，但是當我在我的android服務中實現它時，它不會被調用。這裏的onCreate方法：

public void onCreate() { 
    super.onCreate(); 
    turned= true;  
    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); 
    criteria = new Criteria(); 
    criteria.setAccuracy(Criteria.ACCURACY_FINE); 
    locationManager = (LocationManager) this 
      .getSystemService(LOCATION_SERVICE); 
    String provider = locationManager.getBestProvider(criteria, true); 
    locationManager 
      .requestLocationUpdates(provider, 0, 0, this); ...} 

我真的很感謝所有幫助，服務優良似乎因爲我送麪包和它們被髮送，但onLocationUpdate不會被調用。

編輯：由於Shobhit普里說，它只是需要在onStartCommand（）

public int onStartCommand (Intent intent, int flags, int startId) 
{ 
    super.onCreate(); 
    encendido = true;  
    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); 
    criteria = new Criteria(); 
    criteria.setAccuracy(Criteria.ACCURACY_FINE); 
    locationManager = (LocationManager) this 
      .getSystemService(LOCATION_SERVICE); 
    String provider = locationManager.getBestProvider(criteria, true); 
    locationManager 
      .requestLocationUpdates(provider, 0, 0, this); 
    return START_STICKY; 
}
