Here is the complete code:

String imageUrl = "http://someurl.com/example.png";
URL url = new URL(imageUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.setConnectTimeout(7000);
conn.connect();
BufferedInputStream is = new BufferedInputStream(conn.getInputStream());
Drawable imageDrawable = Drawable.createFromStream(is, imageUrl);
view.setImageBitmap(imageDrawable);

try this for fetching Image :: 

 ImageButton   tran_btn_skip = (ImageButton) findViewById(R.id.tran_btn_skip);

        try {
            Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(
                    "http://www.hermann-uwe.de/files/images/blue_flower.preview_0.jpg")
                    .getContent());
            tran_btn_skip.setImageBitmap(bitmap);
        } catch (Exception e) {
        }

manifest permission: 

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

and try this in mobile device (not in emulator)if you load from your server but, if you load from any another server ten you can show in emulator.

Update::

see

package com.progressbar;

import java.io.InputStream;
import java.net.URL;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.ImageButton;
public class progressbar extends Activity  {


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ImageButton   tran_btn_skip = (ImageButton) findViewById(R.id.login);

        try {
            Bitmap bitmap = BitmapFactory.decodeStream((InputStream) new URL(
                    "http://www.artealdiaonline.com/var/artealdia_com/storage/images/argentina/agenda/exposiciones_muestras/leila_tschopp3/baja-leila_tschopp_-_river_-acrilico_sobre_tela-130x150_cm_-_2011/498599-1-esl-AR/BAJA-Leila_Tschopp_-_River_-acrilico_sobre_tela-130x150_cm_-_2011.jpg")
                    .getContent());
            tran_btn_skip.setImageBitmap(bitmap);
        } catch (Exception e) {
        }

    }
    }

Try this one:

   HttpURLConnection conn = (HttpURLConnection) url.openConnection();
   conn.setDoInput(true);
   conn.setConnectTimeout(7000);
   conn.connect();
   BufferedInputStream is = new BufferedInputStream(conn.getInputStream());
   Drawable drawable = Drawable.createFromStream(is, imageUrl);
   view.setImageBitmap(drawable)
