虚拟机不会让我们分配...下载图片时的字节数

我正在构建一个新闻纸应用程序，因为我需要在gallary视图中显示新闻纸张图像（epaper）...我需要下载大约100张图像。为此，我使用asyncTask和每个下载图像创建新的AsyncTask对象，并且当我尝试下载图像并将其设置为gallary时，我在中间出现错误“VM不会让我们分配......字节”并崩溃应用程序。虚拟机不会让我们分配...下载图片时的字节数

new AsyncTask<String, Void, Bitmap>() { 

       @Override 
       protected Bitmap doInBackground(String... params) { 
        HttpGet httpRequest; 
        try { 
         httpRequest = new HttpGet(new URL(params[0]).toURI()); 
         HttpClient httpClient = new DefaultHttpClient(); 
         HttpResponse response = (HttpResponse) httpClient.execute(httpRequest); 
         HttpEntity entity = response.getEntity(); 
         BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(entity); 
         InputStream is = bufHttpEntity.getContent(); 
         return BitmapFactory.decodeStream(is); 

        } catch (MalformedURLException e) { 
         e.printStackTrace(); 
        } catch (URISyntaxException e) { 
         e.printStackTrace(); 
        } catch (ClientProtocolException e) { 
         e.printStackTrace(); 
        } catch (IOException e) { 
         e.printStackTrace(); 
        }/* catch (Error e) { 
         e.printStackTrace(); 
        }*/ 
        return null; 
       } 

       @Override 
       protected void onPostExecute(Bitmap result) { 
        if(result != null) { 
          img.setImageBitmap(ePaperInfo.getImgJpg1()); 
         notifyDataSetChanged(); 
        } 
       } 


      }
