Help making an app that will display an image that is from a server?

I am making an app that when a button is clicked, it will grab an image from a URL or server and display it.

The above answer seems correct.

Just on the other note, do all this operation in another thread than the UI Thread. And have an ImageView at handy in your layout so that when you have the image in bitmap, you can set that bitmap into the ImageView so that the user can see it.

Since the image can be quite large in size, if downloaded in UI Thread, it'll cause your app to freeze.

Just reformatting the above answer over here:

try { 
   Bitmap bitmap = BitmapFactory.decodeStream(
                 (InputStream)new URL("http://abc.com/image.jpg").getContent()); 
    }catch (MalformedURLException e) { 
        e.printStackTrace(); 
    } catch (IOException e) {
        e.printStackTrace(); 
    }
