Add the following jar to your libs folder.

  • jxmpp-core-0.4.1
  • jxmpp-util-cache-0.4.1
  • minidns-0.1.1
  • smack-android-4.1.0.jar
  • smack-android-extensions-4.1.0
  • smack-core-4.1.0
  • smack-extensions-4.1.0
  • smack-im-4.1.0
  • smack-tcp-4.1.0
  • smack-sasl-provided-4.1.0.jar
    I was having the same problem but after adding the above mentionend JARs, I was able to set up a connection with the server.

I changed 2 jars :

  • jxmpp-core-0.4.1
  • jxmpp-util-cache-0.4.1

At first ,I used these old jars from asmack-master,maybe the main reason is here.

  • jxmpp-core-0.1.0
  • jxmpp-util-cache-0.1.0

I also add other jars that you didn’t mention ,maybe because of the smack_4_1_1.

even though the new exception is coming,I can send message to others…

thanks again!!!
