Sending and Receiving IQ Packets ASMACK/SMACK Android XMPP

Question

I would highly appreciate if someone can help me how to recieve iq packets with ASMACK, i am sending raw iq packets but not able to receive it,

I have registered the iq packets programatically before making a connection but still not getting reponse,

     pm.addIQProvider("vCard", "vcard-temp", new VCardProvider());

---

  final IQ iq = new IQ() {
          public String getChildElementXML() {
            return "<iq from='test@XX.XX.XX.XX' id='v1'      to='test@XX.XX.XX.XX' type='get'><vCard xmlns='vcard-temp'/></iq>";
          }
        };

    iq.setType(IQ.Type.GET);
        connection.sendPacket(iq);
        connection.addPacketListener(new MyPacketListener(),new       PacketTypeFilter(IQ.class));
