Вот как я использую вход

Log.i("XMPP Client", "new Connection and sasl auth done");
try {

Log.i("XMPPClient","Connected to " + xmpp.getHost());

} catch (XMPPException e1) {

e1.printStackTrace();
}
Log.i("XMPP Client", "xmpp connect done");
try {

String apiKey = Session.getActiveSession().getApplicationId();
String sessionKey = Session.getActiveSession().getAccessToken();

String sessionSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

Log.i("XMPP Client", Session.getActiveSession().getApplicationId());
xmpp.login(apiKey + "|" + sessionKey, sessionSecret , "Messenger");

Log.i("XMPPClient"," its logined ");

Log.i("Connected",""+xmpp.isConnected());

if ( xmpp.isConnected()){
Presence presence = new Presence(Presence.Type.available);
xmpp.sendPacket(presence);

}

} catch (XMPPException e) {
e.printStackTrace();
}
}

и это мой класс механизма платформы SASL Facebook
