由於大量數據導致AsyncTask異常

我正在從Android應用程序連接到Java中的RESTful Web服務。我正在使用AsyncTask來獲取數據。它適用於正常數據量。但是當我有大量數據時，Android應用程序會發生異常。我試圖抓住這一例外，但我不能。由於大量數據導致AsyncTask異常

private class LoadingDataFromServer extends AsyncTask<Void, Void, Void> { 

     private boolean outOfMemory = false; 

     @Override 
     public void onPreExecute() { 
      progress = ProgressDialog.show(main_activity, null,"Loading ...", true); 
     } 

     @Override 
     protected void onPostExecute(Void result) { 
      if(outOfMemory) { 
       Toast.makeText(StatisticActivity.this, "Out of memory, select smaller criteria", Toast.LENGTH_SHORT).show(); 
       finish(); 
      } 
      else 
       setListView(); 
      try { 
       progress.dismiss(); 
      } catch (Exception e) { } 
     } 

     @Override 
     protected Void doInBackground(Void... params) { 
      TextView txtProject = (TextView) main_activity.findViewById(R.id.project); 
      txtProject.setBackgroundColor(Color.DKGRAY); 
      txtProject.setText(project); 

      TextView label = (TextView) main_activity.findViewById(R.id.label); 
      label.setText(R.string.deliverable); 
      try { 
      loadStatistic(); 
      } catch (OutOfMemoryError e) { 
       outOfMemory = true; 
       progress.dismiss(); 
      } catch (RuntimeException e) { 
       outOfMemory = true; 
       progress.dismiss(); 
      } catch (Exception e) { 
       outOfMemory = true; 
       progress.dismiss(); 
      } 
      return null; 
     } 
    }

這是我得到的錯誤：

異常在doInBackground發生的事情，但我的例外HANDELING沒有工作。你可以幫我嗎？

聲音像異常告訴你到底發生了什麼錯誤：'由於：java.lang.RuntimeException：無法在未調用Looper.prepare（）的線程中創建處理程序' –
