從URL下載圖像時解碼錯誤

Question

我試圖從urls下載一些圖像，但是我一直爲它嘗試下載的每個圖像都收到解碼錯誤。這是我想要將下載的圖像添加到類數組中的代碼。

for(int i=0;i<jArray.length();i++){ 

       json_data = jArray.getJSONObject(i); 
       Programme Progresult = new Programme(); 

       Progresult.name = json_data.getString("name"); 
       Progresult.event = json_data.getString("event"); 
       Progresult.price = json_data.getString("price"); 


       String imageurl = json_data.getString("preview"); 
       Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageurl).getContent()); 
       Progresult.progpreview = bitmap; 


       arraydata.add(Progresult); 

       } 
      } 
      catch(JSONException e1){ 

       } 
      catch (ParseException e1) { 
       e1.printStackTrace(); 
       } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      return arraydata; 
       } 

這裏是我收到的每個圖像日誌貓錯誤.....

試試這個--->

URL url = new URL(imageurl); 
    HttpURLConnection conn = (HttpURLConnection)url.openConnection(); 
    conn.setConnectTimeout(30000); 
    conn.setReadTimeout(30000); 
    conn.setInstanceFollowRedirects(true); 
    InputStream is=conn.getInputStream(); 
    Bitmap bitmap = BitmapFactory.decodeStream(is); 
    is.close(); 
    conn.disconnect();
