虛擬機不會讓我們分配...下載圖片時的字節數

我正在構建一個新聞紙應用程序，因爲我需要在gallary視圖中顯示新聞紙張圖像（epaper）...我需要下載大約100張圖像。爲此，我使用asyncTask和每個下載圖像創建新的AsyncTask對象，並且當我嘗試下載圖像並將其設置爲gallary時，我在中間出現錯誤「VM不會讓我們分配......字節」並崩潰應用程序。虛擬機不會讓我們分配...下載圖片時的字節數

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(); 
        } 
       } 


      }
