Android Google Maps API V2 OutOfMemory異常

Question

我有數據列表視圖，每個項目打開一個嵌入了地圖的視圖。這張地圖的目的是顯示一個標記。代碼工作正常，但如果我有很多列表項（50+），來回騎車會導致應用程序拋出OutOfMemory異常。

有人可以幫助我瞭解我在做什麼錯誤在這裏..我猜測，我的地圖初始化邏輯中有什麼問題導致這..我試圖弄清楚。

public class DetailView extends Fragment implements OnInfoWindowClickListener { 

    private MapView mMapView; 
    private GoogleMap googleMap; 

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

      mMapView = (MapView) v.findViewById(R.id.mapBusinessLocation); 
      mMapView.onCreate(savedInstanceState); 
      mMapView.onResume();//needed to get the map to display immediately 

      MapsInitializer.initialize(this.getActivity()); 
      //MapController myMapController = mMapView.getController(); 
      googleMap = mMapView.getMap(); 
      googleMap.setMyLocationEnabled(true); 
      CameraUpdate center= 
        CameraUpdateFactory.newLatLng(new LatLng(-20.269927,57.672729)); 
      CameraUpdate zoom=CameraUpdateFactory.zoomTo(15); 

      googleMap.moveCamera(center); 
      googleMap.animateCamera(zoom); 
    } 

     @Override 
     public void onActivityCreated(Bundle savedInstanceState) { 
      super.onActivityCreated(savedInstanceState); 

     placeMarker("test"); 

     } 

     private Marker placeMarker(String title) { 
      //Get the hue 
      String pinColor = "#f29217";  
      int c = Color.parseColor(pinColor); 
      float[] pixelHSV = new float[3]; 
      Color.colorToHSV(c, pixelHSV); 
      return googleMap.addMarker(new MarkerOptions() 
      .position(new LatLng(-20.269927,57.672729)) 
      .title(title) 
      .snippet("") 
      .icon(BitmapDescriptorFactory.defaultMarker(pixelHSV[0]))); 
     } 
      @Override 
     public void onResume() { 
      super.onResume(); 

       if(mMapView != null) { 
       mMapView.onResume(); 
       } 
     } 

     @Override 
     public void onPause() { 
      super.onPause(); 

       if(mMapView != null) { 
       mMapView.onPause(); 
       } 
     } 

     @Override 
     public void onDestroy() { 
      super.onDestroy(); 

       if(mMapView != null) { 
       mMapView.onDestroy(); 
       } 

     } 

     @Override 
     public void onLowMemory() { 
      super.onLowMemory(); 

       if(mMapView != null) { 
       mMapView.onLowMemory(); 
       } 
     } 

} 

堆棧跟蹤，當應用程序崩潰，在下面給出..

Answer 1

是你的工作是什麼Android版本？因爲在較早的（2.3-）Android版本中，Bitmap不會被垃圾收集器自動清除。也檢查出這個答案：Bitmap, Bitmap.recycle(), WeakReferences, and Garbage Collection
