                    @Override
                    protected IQChildElementXmlStringBuilder getIQChildElementBuilder(IQChildElementXmlStringBuilder xml) {
                        xml.setEmptyElement();
                        return xml;
                    }
                };
                iq.setType(IQ.Type.get);

                iq.addExtension();
                iq.setTo(AppConstants.CHAT_HOSTNAME);

                connection.sendStanza(iq);
            } catch (SmackException.NotConnectedException e) {
                e.printStackTrace();
            } catch (InterruptedException e) {
