Android – Just Use Smack API For XMPP
OUTDATED SAMPLE – Updated code is here:
http://davanum.wordpress.com/2008/12/29/updated-xmpp-client-for-android/
Using Smack XMPP API From Android
Once you get tired of the limitations of android’s built-in IMProvider and the corresponding API – IXmppSession and IXmppService, try the sample below. Inside the source/binary zip (bottom of this article) you will find a smack.jar that works with android. To build the jar yourself, You can download the Smack 3.0.4 sources from here and apply the patch here.
Here Is A Screen Shot Of The XMPP Settings Dialog.
Notes
- For GTalk, use “gtalk.google.com” as host with port 5222. The service name is “gmail.com”
- Don’t add “@gmail.com” in the user name, just the id will do
