Обновление местоположения прекращает использование NETWORK_PROVIDER после перезагрузки устройства

Question

В моем приложении Обновление местоположения прекращается после перезагрузки устройства. Я использую как gps, так и сеть, чтобы найти текущее местоположение в моем приложении, после перезагрузки gps работает правильно, но когда я отключу gps, приложение, к сожалению, закрыто. это моя проблема

это мой код Servicestart.java

public class Servicestart extends Service { 


    boolean gps_enabled = false; 
    boolean network_enabled = false; 

    @Override 
    public IBinder onBind(Intent arg0) { 
     // TODO Auto-generated method stub 
     return null; 
    } 
@Override 
public void onCreate() { 
    // TODO Auto-generated method stub 
    Log.i("service started", "start"); 


     final LocationManager locMan = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
     if(userFunctions.isUserLoggedIn(getApplicationContext())){ 




    if(Broadcast.check==false) 
    { 
     LocationListener locatioListner = new LocationListener() { 


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

      } 

      public void onProviderEnabled(String provider) { 
       // TODO Auto-generated method stub 

      } 

      public void onProviderDisabled(String provider) { 
       // TODO Auto-generated method stub 
       get(); 
      } 

      public void onLocationChanged(Location location) { 

       Log.i("location", "loc"); 
       String latitude=String.valueOf(location.getLatitude()); 
       String longtitude=String.valueOf(location.getLongitude()); 
       //location updated starts here 



       } 

     }; 
     locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locatioListner); 

    } 





     } 

} 

void get() 
{ 

    final LocationManager locMan = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    gps_enabled = locMan.isProviderEnabled(LocationManager.GPS_PROVIDER); 
    network_enabled = locMan.isProviderEnabled(LocationManager.NETWORK_PROVIDER); 

    if (!gps_enabled && !network_enabled) { Context context = getApplicationContext(); 
    int duration = Toast.LENGTH_SHORT; 
    Toast toast = Toast.makeText(context, "nothing is enabled", duration); 
    toast.show(); 

} 



    LocationListener locatioListnerGps = new LocationListener() { 

      public void onStatusChanged(String provider, int status, Bundle extras) { 

      } 

      public void onProviderEnabled(String provider) { 

       Toast.makeText(getApplicationContext(), "gpsenabled", 1000).show(); 
      } 

      public void onProviderDisabled(String provider) { 
       Toast.makeText(getApplicationContext(), "gps disable", 1000).show(); 

       get(); 

      } 

      public void onLocationChanged(Location location) { 

       String latitude=String.valueOf(location.getLatitude()); 
       String longtitude=String.valueOf(location.getLongitude()); 
       //location updated starts here 

      } 
     }; 
     LocationListener locationListenerNetwork = new LocationListener() { 

       public void onStatusChanged(String provider, int status, Bundle extras) { 

       } 

       public void onProviderEnabled(String provider) { 

        Toast.makeText(getApplicationContext(), "gpsenabled", 1000).show(); 
       } 

       public void onProviderDisabled(String provider) { 

        Toast.makeText(getApplicationContext(), "gps disable", 1000).show(); 
        get(); 


       } 

       public void onLocationChanged(Location location) { 

        String latitude=String.valueOf(location.getLatitude()); 
        String longtitude=String.valueOf(location.getLongitude()); 
        //location updated starts here 

       } 
      }; 


    if (gps_enabled) 
    { 
    locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, 
      locatioListnerGps); 
    locMan.removeUpdates(locationListenerNetwork); 
    } 
    if(network_enabled){ 
    locMan.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, 
      locationListenerNetwork); 
    locMan.removeUpdates(locatioListnerGps); 
} 

} 
} 

пожалуйста, помогите и направлять меня ...

, потому что я beginer

Спасибо заранее ...

if (gps_enabled) 
    { 
    locMan.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, 
      locatioListnerGps); 
    locMan.removeUpdates(locationListenerNetwork); 
    } 
    if(network_enabled){ 
    locMan.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, 
      locationListenerNetwork); 
    locMan.removeUpdates(locatioListnerGps); 
} 

Проверьте свой код первым. Почему вы удаляете обновления здесь?

Чтобы запустить службу на ботинке, пожалуйста, добавьте в манифесте:

Попробуйте этот код и дайте мне знать: Service код для обновления местоположения:
