Android asmack issue in configuring

When I configure the xmpp client via asmack, the connection is established successfully but after that I get the following error in log-cat. Therefore I am unable to send an iq via xmpp, as I don’t get any response in my handler neither I get any more details of errors or issues in logcat. What should I do?
