Hello Guys,


Here I am writing easiest way to download image from server. Following function return Drawable object.  Use drawable object as per your  requirement.

01	private Drawable LoadImageFromWeb(String url) {

02

try {

03	InputStream is = (InputStream) new URL(url).getContent();

04	Drawable d = Drawable.createFromStream(is, "src name");

05

return d;

06	} catch (Exception e) {

07	System.out.println("Exc=" + e);

08	return null;

09

}

10

}
