內存不足錯誤 - 當添加在GoogleMap的標記，使位圖

Question

當地圖加載但地圖位置移動到其它位置和新的標誌出現後...

這裏是堆棧跟蹤不會發生此錯誤：

這裏是我創建位圖：

public Bitmap loadBitmapFromView(View v) { 

     try { 
      if (v.getMeasuredHeight() <= 0) { 
       v.measure(WindowManager.LayoutParams.WRAP_CONTENT, WindowManager.LayoutParams.WRAP_CONTENT); 
        Bitmap bActual = Bitmap.createBitmap(v.getMeasuredWidth(), v.getMeasuredHeight(), Bitmap.Config.ARGB_8888); 
      Bitmap b = Bitmap.createScaledBitmap(bActual, 120, 120, true); 
       Canvas c = new Canvas(b); 
       v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight()); 
       v.draw(c); 
       return b; 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
      return null; 
     } 
     return null; 
    } 

這就是所謂的我的doInBackground在我AsyncTask，如：

MarkerOptions marker = new MarkerOptions() 
         .position(LOC) 
         .snippet(user) 
         .title(name) 
         .icon(BitmapDescriptorFactory.fromBitmap(loadBitmapFromView(v1))); 

在onPostExecute中，我添加了數據庫發現的尚未顯示的新標記。

  for (int i = 0; i < markers.get(i).nl.size() - 1; i++) { 
       Marker m = googleMap.addMarker(markers.get(i).mO.get(i)); 
       markerIdMap.put(m, markers.get(i).nl.get(i)); 
      } 

這是我如何設置我的地圖：

其他花絮：

googleMap.setClustering(new ClusteringSettings().enabled(false) 
      .addMarkersDynamically(true)); 

    googleMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() { 
     @Override 
     public void onCameraChange(CameraPosition cp) { 

      LOC = cp.target; 
      MainActivity.mLongitude = LOC.longitude; 
      MainActivity.mLatitude = LOC.latitude; 

      if (!running) { 
       new NearLocationsTask().execute(); 
      } 
     } 
    }); 

，我使用android-map-extensions

我不知道，如果你真的創建一個空位圖並將其縮放：

位圖bActual = Bitmap.createBitmap（v.getMeasuredWidth（），v.getMeasuredHeight（），Bitmap.Config.ARGB_8888）;

位圖b = Bitmap.createScaledBitmap（bActual，120,120，true）;

如果你有很多標記，也許你試圖分配太多的位圖。
