は更新された場所を取得できませんでした

Question

私のアプリケーションでは、私は現在の場所を取得するために10秒のタイマーを設定していますlocationManager.requestLocationUpdates（）;が、問題助けて...以下

がサービスで書かれた私のコードです..私が更新された場所ではなく、それはアプリケーションが起動している同じ緯度と経度を与え得るcouldntのことであると提案が

public class DemoService extends Service{ 


    LocationManager locationManager; 
    public Timer timer; 
    public static int i; 
    private String FILE_NAME = "location.txt"; 
    @Override 
    public IBinder onBind(Intent intent) { 
     // TODO Auto-generated method stub 
     return null; 
    } 

    @Override 
    public void onStart(Intent intent, int startId) { 
     // TODO Auto-generated method stub 
     super.onStart(intent, startId); 

     locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); 

     Toast.makeText(getApplicationContext(), "onStart()....", Toast.LENGTH_SHORT).show(); 
     timer = new Timer(); 
     timer.schedule(new mainTask(), 0, 10*1000); 

    } 

    @Override 
    public void onCreate() { 
     // TODO Auto-generated method stub 
     super.onCreate(); 

     Toast.makeText(getApplicationContext(), "onCreate()....", Toast.LENGTH_SHORT).show(); 
    } 

    @Override 
    public void onDestroy() { 
     // TODO Auto-generated method stub 
     super.onDestroy(); 
     Toast.makeText(getApplicationContext(), "onDestroy()....", Toast.LENGTH_SHORT).show(); 
     timer.cancel(); 
    } 

    private class mainTask extends TimerTask 
     { 
      public void run() 
      { 
       toastHandler.sendEmptyMessage(0); 
      } 
     }  



     private final Handler toastHandler = new Handler() 
     { 
      @Override 
      public void handleMessage(Message msg) 
      { 
       Toast.makeText(getApplicationContext(), "test "+(i), Toast.LENGTH_SHORT).show(); 
       locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, new MyLocationListerner()); 
      } 
     };  


     public class MyLocationListerner implements LocationListener{ 


      @Override 
      public void onLocationChanged(Location location) { 
       // TODO Auto-generated method stub 
       i++; 
       Toast.makeText(DemoService.this, "\nLat : "+location.getLatitude()+"\nLog : "+location.getLongitude(), Toast.LENGTH_SHORT).show(); 
       saveToFile(location); 
       locationManager.removeUpdates(this); 

      } 

      @Override 
      public void onStatusChanged(String provider, int status, Bundle extras) { 
       // TODO Auto-generated method stub 

       Toast.makeText(DemoService.this,"Got onLocationChanged..",Toast.LENGTH_SHORT).show(); 
       System.out.println("Got onStatusChanged"); 

      } 

      @Override 
      public void onProviderEnabled(String provider) { 
       // TODO Auto-generated method stub 
       Toast.makeText(DemoService.this,"Got onLocationChanged..",Toast.LENGTH_SHORT).show(); 
       System.out.println("Got onProviderEnabled"); 
      } 

      @Override 
      public void onProviderDisabled(String provider) { 
       // TODO Auto-generated method stub 
       Toast.makeText(DemoService.this,"Got onLocationChanged..",Toast.LENGTH_SHORT).show(); 
       System.out.println("Got onProviderDisabled"); 
      }
