android getting error while displaying image from url

Question

When i'm displaying image from url with using below code, application is taking too much time to load images from server. Application is hanging up if we have 8-10 images to load.

Bitmap mbmp = BitmapFactory.decodeStream(new java.net.URL("urlname").openStream());
Imageview_ref.setImageBitmap(mbmp);

and getting this in Logcat

with this logcat error message i'm still getting output.

this is my updated code view..

public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            View v = convertView;
            if(v == null){
                LayoutInflater vl = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                v = vl.inflate(R.layout.placeslist, null);
            }
            Fields o = results.get(position);

            if (o != null) {
                TextView iv = (TextView)v.findViewById(R.id.toptext);
                ImageView tv_Image = (ImageView)v.findViewById(R.id.Locimage);

                iv.setText(o.getLocationName());                            

                try {
                    Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(o.getLocationImage()).getContent());
                    tv_Image.setImageBitmap(bitmap);
                } catch (Exception e) {
                    e.printStackTrace();
                }


            }
            return v;
        }       
    }

logcat shows that you are not closing your cursor and database

onDestroy() method of your activity, add this

try{
   cursor.close();
   db.close(); 
}catch(exception e)
{}

Please try this ::

            try {
        Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(
                "http://xyz.com/a/f/a.png")
                .getContent());
        tran_btn_skip.setImageBitmap(bitmap);
    } catch (Exception e) {
    }

Make sure you have to give permission of Internet
