inputstream - Using imageview by url in android -


i try photo url not photo.

current code:

public class indexactivity extends activity { @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main);     imageview = (imageview) findviewbyid(r.id.imageview1);     bitmap bitmap = downloadimage("http://www.gophoto.it/view.php?i=http://1.bp.blogspot.com/-2ltvccufbkc/t3l3kgctj2i/aaaaaaaabbq/ki60e1lu9se/s1600/sachin%2btendulkar.png");     i.setimagebitmap(bitmap); }  private inputstream openhttpconnection(string urlstring) throws ioexception {     inputstream in = null;     int response = -1;      url url = new url(urlstring);     urlconnection conn = url.openconnection();      if (!(conn instanceof httpurlconnection))         throw new ioexception("not http connection");      try {         httpurlconnection httpconn = (httpurlconnection) conn;         httpconn.setallowuserinteraction(false);         httpconn.setinstancefollowredirects(true);         httpconn.setrequestmethod("get");         httpconn.connect();         response = httpconn.getresponsecode();         if (response == httpurlconnection.http_ok) {             in = httpconn.getinputstream();         }     } catch (exception ex) {         throw new ioexception("error connecting");     }     return in; }  private bitmap downloadimage(string url) {     bitmap bitmap = null;     inputstream in = null;     try {         in = openhttpconnection(url);         bitmap = bitmapfactory.decodestream(in);         in.close();     } catch (ioexception e1) {         // todo auto-generated catch block         e1.printstacktrace();     }     return bitmap;     } }

and the loccat :

what doing wrong calling long running task on main ui thread.

use asyncktask's onpostexecute method downloaded image bitmap. bind imageview object returned bitmap.
