MapFragment Сбои после приложения убит на фоне

Question

Реализовать Внесите свой проект, как этот

из XML

<fragment 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="250dp" 
     class="com.google.android.gms.maps.MapFragment"/> 

от Явы

public class Search extends Fragment implementsOnMapReadyCallback { 
    View rootView; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

... 
loadMap(); 
... 
} 

GoogleMap map; 
MapFragment mapFragment; 

    public void loadMap() { 
     if (mapFragment == null) { 
      mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map); 
      mapFragment.getMapAsync(this); 
     } 
    } 

@Override 
    public void onMapReady(GoogleMap googleMap) { 
     map = googleMap; 
     map.setMyLocationEnabled(true); 
     map.getUiSettings().setZoomControlsEnabled(true); 
    } 

@Override 
    public void onDestroy() { 
     super.onDestroy(); 
     getFragmentManager().beginTransaction().remove(mapFragment).commit(); 
    } 

Это прекрасно работает даже тогда, когда я переход от одного фрагмента другому. Однако, через некоторое время, например, когда приложение работает в фоновом режиме в течение длительного времени, когда я снова попробуйте запустить приложение, он просто падает приложение и я получаю эту ошибку

Как это исправить.

Answer 1

Я думаю, что эту ошибку можно игнорировать, и приложение должно загружаться просто отлично. Попробуйте следующее:

View rootView; 

public View onCreateView(LayoutInflater inflater, 
          ViewGroup container, Bundle savedInstanceState) 
    { 
     // The last two arguments ensure LayoutParams are inflated 
     // properly. 
     if (rootView != null) 
     { 
      ViewGroup parent = (ViewGroup) rootView.getParent(); 
      if (parent != null) 
       parent.removeView(rootView); 
     } 

     try 
     { 
      rootView = inflater.inflate(R.layout.yourMapFragment, container, false); 
     } 
     catch(InflateException ex) 
     { 
     } 

     ... 
     return rootView; 
    }
