function downloadurl:

private inputstream downloadurl(string urlstring) throws ioexception {     url url = new url(urlstring);     httpurlconnection conn = (httpurlconnection) url.openconnection();     conn.setreadtimeout(10000 /* milliseconds */);     conn.setconnecttimeout(15000 /* milliseconds */);     conn.setrequestmethod("get");     conn.setdoinput(true);     // starts query     conn.connect();     // line 475     return conn.getinputstream(); }

it turns out there problem dns server data provider. because server changed ip-addresses , dns server not yet updated.
