I\'m trying to make a Facebook Chat on Android with the Smack library. I\'ve read the Chat API from Facebook, but I cannot understand how I have to authenticate with Faceboo
What do you want to do?
If you just want to login on FB chat, you connect to FB just like any other XMPP server.
I would look at and use "Authenticating with Username/Password" from Chat API, wich is supported by Smack. Unless I would like to write an FaceBook-application. Then I would try to login in with "Authenticating with Facebook Platform".
So, just use Smack to connect to FB chat as you would do with your ordinary Jabber client.
