Android 위치 관리자가 호출 될 때 앱이 다운 됨

Question

사용자가 버튼을 클릭 할 때마다 기기의 현재 위치를 가져 오는 코드를 작성했습니다. 하지만 청취자에게 전화를 걸면 앱이 충돌합니다. 누구든지 내가 잘못한 것을 통찰 해 줄 수 있습니까? 미리 감사드립니다.

public void onStartService() 
{ 
    addListenerLocation(); 
} 

@SuppressLint("NewApi") 
private void addListenerLocation() 
{ 
    mLocationManager = (LocationManager) 
      getSystemService(Context.LOCATION_SERVICE); 
    LocationListener mLocationListener = new LocationListener() 
    { 

     public void onLocationChanged(Location location) 
     { 
      currentLat = location.getLatitude(); 
      InstanciaObjetos.setPEDLAT(currentLat); 
      currentLon = location.getLongitude(); 
      InstanciaObjetos.setPEDLON(currentLon); 
     } 
     public void onStatusChanged(String provider, int status, Bundle extras) 
     { 
      //TODO -- Barney says what should happen 
     } 
     public void onProviderEnabled(String provider) 
     { 
      Location lastKnownLocation = mLocationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER); 
      if(lastKnownLocation!=null) 
      { 
       currentLat = lastKnownLocation.getLatitude(); 
       currentLon = lastKnownLocation.getLongitude(); 
      } 

     } 
     public void onProviderDisabled(String provider) 
     { 

     } 
    }; 
    mLocationManager.requestLocationUpdates(
      LocationManager.GPS_PROVIDER, 0, 0, mLocationListener); 
} 

서비스를 시작 난 그냥() onStartService를 호출합니다. 내가해야 할 일이 더 있니?

방금 ​​logcat을 첨부했습니다. 이제 나는해야 할 일이 무엇인지 깨달았다. 대신 서비스의 onCreate() 방법
