How to use Smack with android

I have following code which uses smack 4.1.0 for connection with xmpp server im.koderoot.net, this host/service is working for java application for which I have used smack3.1.0 and smacx3.1.0 but in java when I am using the jars it throws the following exception

09-01 18:29:18.921: E/SMACK EXCEPTION(1577): org.jivesoftware.smack.SmackException$ConnectionException: The following addresses failed: im.koderoot.net:5222 Exception: null

MainActivity.java

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        connect = (Button) findViewById(R.id.button1);
        connect.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
          XMPPTCPConnectionConfiguration.XMPPTCPConnectionConfigurationBuilder builder = XMPPTCPConnectionConfiguration.builder();

            builder.setUsernameAndPassword("xxxx", "xxxx");
            builder.setRosterLoadedAtLogin(true);


            mConnection = new XMPPTCPConnection(builder.build());
            //Set ConnectionListener here to catch initial connect();
          //  mConnection.addConnectionListener(this);

            try {
                mConnection.connect();
                mConnection.login();
                Toast.makeText(getApplicationContext(), "Sucess", Toast.LENGTH_LONG).show();

                Toast.makeText(getApplicationContext(), "XMPP Exception"+e, Toast.LENGTH_LONG).show();

    }


}

I have following .jar files in project

smack-android-4.1.0-alpha6.jar

smack-tcp-4.1.0-alpha6.jar

minidns-0.1.1.jar

smack-sasl-provided-4.1.0-alpha6.jar

smack-core-4.1.0-alpha6.jar

smack-resolver-minidns-4.1.0-alpha6.jar

jxmpp-util-cache-0.4.0-alpha2.jar

jxmpp-core-0.4.0.jar

I found a following working solution myself

Replace all the jar files by asmack-2010.05.07.jar and asmack-jse-buddycloud-2010.12.11.jar

And Change the code to following

ConnectionException is thrown when host cannot be reached.

Check following things may help you.

  1. forget to add permission at the manifest file (I do this a lot of time)

uses-permission android:name="android.permission.INTERNET"

  1. check if it can ping im.koderoot.net from your Android device
  2. add e.printStackTrace(); at exception catch will give more hints

I have just registered at im.koderoot.net and use smack4.1.3 to connect without problem.

One more thing is that your code will cause ANR (Application Not Responding) in long run, but it is another topic.
