我对用于 android xmpp 连接的 asmack java 库有疑问。
我的问题是我无法使用此代码获取我的联系人 vCard 或我自己的电子名片:
VCard vCard = new VCard();
try {
//SmackConfiguration.setPacketReplyTimeout(300000);
vCard.load(conexion.getConnection(),u.get_jid());
} catch (XMPPException e) {
e.printStackTrace();
} catch (NullPointerException e) {
// TODO: handle exception
}
对于所有请求,都会出现错误:“No vCard for xxx @ xxxx”;
并且已经使用:
configure(ProviderManager.getInstance());
并调用所有负责制作提供者的类:
private void configure(ProviderManager pm) {
Log.d("XMPPChatDemoActivity", "Entro al configure");
// Private Data Storage
pm.addIQProvider("query","jabber:iq:private", new PrivateDataManager.PrivateDataIQProvider());
// Time
try {
pm.addIQProvider("query","jabber:iq:time", Class.forName("org.jivesoftware.smackx.packet.Time"));
} catch (ClassNotFoundException e) {
Log.w("Error", "Can't load class for org.jivesoftware.smackx.packet.Time");
}

} catch (ClassNotFoundException e) {
Log.w("Error", "Can't load class for org.jivesoftware.smackx.packet.Version");
}
// VCard
pm.addIQProvider("vCard","vcard-temp", new VCardProvider());

}
即使在这一切之后,我仍然无法获得任何用户的电子名片。
