If you are just trying to make the ImageView display an image from a URL use
this function.


    private Bitmap decodeImage(String url) {

     URL aURL;

     try {

     aURL = new URL(url);

     URLConnection conn = aURL.openConnection();

     conn.connect();

     InputStream is = conn.getInputStream();

     BufferedInputStream bis = new BufferedInputStream(is);

     Bitmap bm = BitmapFactory.decodeStream(bis);

     bis.close();

     is.close();

     return bm;

     } catch (MalformedURLException e) {

     e.printStackTrace();

     } catch (IOException e) {

     e.printStackTrace();

     }

     return null;

     }
}


call the function as
imgView.setImageBitmap(decodeImage("http://sss.jpg";));
