java - Http request - already connected -

basically i've been using these particular lines of code quite time , never had problems it. nothing's been touched i'm getting

illegalstateexception - connected

exactly after set conn.setusescaches(false)

 public void putimagetos3(string signedurl, bitmap image) throws wampnetworkexception, ioexception {             url url = new url(signedurl);             httpurlconnection conn = (httpurlconnection) url.openconnection();             conn.getdooutput();             conn.setusecaches(false);             conn.setrequestmethod("put");             conn.addrequestproperty("content-type", "image/jpeg");             conn.addrequestproperty("connection", "close");             outputstream out = new bufferedoutputstream(conn.getoutputstream());             image.compress(bitmap.compressformat.jpeg, 100, out);              if (conn.getresponsecode() != httpurlconnection.http_ok) {                 throw new ioexception("failed upload image s3: "                         + conn.getresponsecode() + conn.getresponsemessage() + "\r\n");             }             out.flush();             out.close();             conn.disconnect();         } 

write code in try-finally block , try

public void putimagetos3(string signedurl, bitmap image) throws wampnetworkexception, ioexception {         try{         url url = new url(signedurl);         httpurlconnection conn = (httpurlconnection) url.openconnection();         conn.getdooutput();         conn.setusecaches(false);         conn.setrequestmethod("put");         conn.addrequestproperty("content-type", "image/jpeg");         conn.addrequestproperty("connection", "close");         outputstream out = new bufferedoutputstream(conn.getoutputstream());         image.compress(bitmap.compressformat.jpeg, 100, out);          if (conn.getresponsecode() != httpurlconnection.http_ok) {             throw new ioexception("failed upload image s3: "                     + conn.getresponsecode() + conn.getresponsemessage() + "\r\n");         }      }      finally{         out.flush();         out.close();         conn.disconnect();       }     }
