BitmapFactory无法解码流：Android中的java.io.FileNotFoundException

Question

我试图从我的数据库在线获取图片，在我的“图片链接”这是我的表中的数据字段，我把那里我上传的图片的网址，但不幸的是它给了我这个错误。

02-08 15:05:29.432 14364-14364/com.example.jithea.testlogin E/BitmapFactory﹕ Unable to decode stream: java.io.FileNotFoundException: /http:/agustiniancampusevents.site40.net/newsDB/images/Visual%20Report%20Filipino%20Final-12%20copy.JPG: open failed: ENOENT (No such file or directory) 

这是我在onPostExecute代码：

protected void onPostExecute(String file_url) { 
     // dismiss the dialog after getting all products 
     pDialog.dismiss(); 
     // updating UI from Background Thread 
     runOnUiThread(new Runnable() { 
      public void run() { 
       /** 
       * Updating parsed JSON data into ListView 
       * */ 


       ListAdapter adapter = new SimpleAdapter(
         NewsActivity.this, productsList, 
         R.layout.news_list_item, new String[]{TAG_PID, TAG_IMAGELINK, 
         TAG_NEWSTITLE, TAG_DESCRIPTION}, 
         new int[]{R.id.pid, R.id.imageView, R.id.newstitle, R.id.description}); 
       // updating listview 
       setListAdapter(adapter); 
      } 
     }); 

    }

使用BitmapFactory.decodeStream而不是BitmapFactory.decodeFile。

try (InputStream is = new URL(file_url).openStream()) { 
    Bitmap bitmap = BitmapFactory.decodeStream(is); 
}
