error while parsing rss feed for stackoverflow.com

error while parsing rss feed for stackoverflow.com

i am trying to create rss feeds app that parses all the websites
supporting feed. i used Jsoup for this purpose. and parsed for different
type of rss in this way
org.jsoup.select.Elements links =
doc.select("link[type=application/rss+xml]"); org.jsoup.select.Elements
links = doc.select("link[type=application/atom+xml]");
it parses various websites like engadget.com, ndtv.com etc but when i
tried to pase websites like stackoverflow.com or 1up.com i got the
following error.
thread exiting with uncaught exception (group=0x40efe378)
and
Caused by: java.lang.IllegalStateException: Target host must not be null,
or set in parameters. scheme=null, host=null, path=/rss
searching for error #1 didnt yield even 1 results. searching for eroror #2
had many. all stated to use http:// before any websites url like
http://1up.com
but then too the error persists. and i had already implemented this before
since all other websites rss are parsed. this is my logcat for 1up.com rss
feed.
