For my application I need to import the Gmail Address book, which I am able to do by following "Gmail Contact API".
Recently Gmail added some of the new fields(i.e. Birthday,Website etc) which are not the part of xml. The gmail api docs mention that the new added field is part of XML namespace http://schemas.google.com/contact/2008, but I am unable to figure it out that how to fetch new fields using this name space which I am able to extract.
