i am using facebook SDK 3.0 i have to get profile picture of user login. Here is the code I use:
URL image_value = new URL(\"http://graph.facebook.com/\"+id
You should change your code following:
URL image_value = new URL("http://graph.facebook.com/"+id+"/picture" );
Possible GET parameters for the URL can be found here: https://developers.facebook.com/docs/graph-api/reference/user/picture/
