XMPP / asmack / android / Google Talk

OK, I finally figured out how to send and receive XMPP instant messages from my gmail account using asmack with an Android 2.1 AVD. For some reason, the event-driven message receive code doesn't work, but this polling example code does. Here's my latest source:

    public int state = 0;
    private static final String TAG = "HelloFormStuffActivity"; 
    
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);       
        
        new Thread(new Runnable() {
          public void run() {            
            //XMPPConnection xmpp = new XMPPConnection("jabber.iitsp.com");
            XMPPConnection xmpp = new XMPPConnection("gmail.com");
            try {
              xmpp.connect();

              // for other jabber accounts, truncate after the @
              //xmpp.login("username", "password"); 

              // for gtalk / gmail, include the @
              xmpp.login("your-gmail-account@gmail.com", "your-gmail-password");

            } catch (XMPPException e) {
              Log.v(TAG, "Failed to connect to " + xmpp.getHost());
              e.printStackTrace();

            ChatManager chatmanager = xmpp.getChatManager();
            Chat newChat = chatmanager.createChat("friend@gmail.com", new MessageListener() {
              // THIS CODE NEVER GETS CALLED FOR SOME REASON
              public void processMessage(Chat chat, Message message) {
                try {
                  Log.v(TAG, "Got:" + message.getBody());
                  chat.sendMessage(message.getBody());
                } catch (XMPPException e) {
                  Log.v(TAG, "Couldn't respond:" + e);

            PacketFilter filter 
                = new AndFilter(new PacketTypeFilter(Message.class), 
                                new FromContainsFilter("friend@gmail.com"));

            // Collect these messages
            PacketCollector collector = xmpp.createPacketCollector(filter);
            
            while(true) {
              Packet packet = collector.nextResult();
                
              if (packet instanceof Message) {
                Message msg = (Message) packet;
                // Process message

        }).start();
        
        //setContentView(this);
    }
