为什么无法将位图添加到位图数组列表

Question

为什么无法在 asynktask 内的位图数组列表中添加位图。

public static class YourMoves_Players extends AsyncTask<String, String, String> {
//  static String yourmove_players[];
    @Override
    protected String doInBackground(String... args) {
        boolean failure = false;
        // TODO Auto-generated method stub
         // Check for success tag
       int success;
       Log.d("login.on create","YOURMOVE_PLAYERS Background");
       try {
           // Building Parameters
           List<NameValuePair> params = new ArrayList<NameValuePair>();
           params.add(new BasicNameValuePair("playerid", fb_id));//player_id
           Log.d("request!", "starting");
           //Posting user data to script 
           JSONObject json = jsonParser.makeHttpRequest(
                  GETYOURMOVE_URL, "POST", params);
           if(json == null)
           {
            Log.d("json","json returning null");
               return null;
           }
           success = json.getInt(TAG_SUCCESS);
           if (success == 1) {
            products = json.getJSONArray(TAG_PRODUCTS);
            Log.d("Notification","BEFORE FOR LOOP");
            Log.d("",products.length()+" LENGTH");
                for (int i = 0; i < products.length(); i++) {
                    JSONObject c = products.getJSONObject(i);
                    String yourmove_pid = c.getString(TAG_YOURMOVE_ID); 
                    String player_name = c.getString(TAG_YOURMOVE_NAME);
                //  yourmove_pic.add(Get_FB_Image.getFBImage(yourmove_pid));
                    Players player=new Players(yourmove_pid,player_name);
                    yourmove_list.add(player);
                    yourmove_id.add(yourmove_pid);
                    yourmove.add(player_name);
                    Log.d("Vs_facebook","going to add bitmap facebook image");
                    yourmove_pic.add(Get_FB_Image.getFBImage(yourmove_pid));
                    Log.d("Vs_facebook"," facebook image added");
            Log.d("User Created!", json.toString()+"CONGRETS");
                }

                Log.d("","AFTER FOR LOOP yourmove_id  "+yourmove_id);
            return json.getString(TAG_MESSAGE);
           }else{
            Log.d("Login Failure!", "SUCCESS FAILED");
            return json.getString(TAG_MESSAGE);
           }
       } catch (JSONException e) {
           e.printStackTrace();
       }
       catch(Exception e){}
       return null;
    }
    /**
    * After completing background task Dismiss the progress dialog
    * **/

} 

"yourmove_pic"是一个位图数组列表，"Get_FB_Image.getFBImage（yourmove_pid）"是获取用户Facebook个人资料图像的方法。 但是我的应用程序在执行此行之前卡住了. 在执行此行之前收到我正在打印的日志消息。
那么有什么问题请帮忙

在我的getFBImage中，我得到了这样的个人资料图片

URL img_value = null;
img_value = new URL("http://graph.facebook.com/"+fb_id+"/picture?type=small");
fb_image = BitmapFactory.decodeStream(img_value.openConnection().getInputStream());
return fb_image;

Answer 1

据

我说，这应该通过内存错误异常并进行处理，这里有一些链接可以帮助您解决此问题：使用列表，链接列表和哈希映射时内存不足时出错

可以使用 LRU 缓存处理内存不足错误

Answer 2

也许Get_FB_Image.getFBImage(yourmove_pid)解码流并返回位图。如果是这种情况，也许流的解码以生成位图尚未完成，这就是为什么应用程序在获取位图时卡住的原因。
