Question

I am trying to make aSmack work in my project.
Created a standard project in eclipse, added the jar to build path / libraries. Started using the XMPP classes, but I am not sure if there’s something else I should do to properly set up the project (later on that), since it’s not working.
In a Service, I start an AsnycTask to connect to google talk and send one chat message.

conn1 = new XMPPConnection(config);
// connecting to the server
try {
    conn1.connect();
    Log.v(LOG_TAG, "XMPP connected");
} catch (XMPPException xe) {
    msg = "XMPPException during connect(): " + xe.getMessage();
    Log.v(LOG_TAG, msg);
}

// login
try {
    conn1.login(USERNAME, PASSWORD, RESOURCE);
    msg = "login ok";
    Log.v(LOG_TAG, msg);
} catch (XMPPException xe) {
    msg = "XMPPException login(): " + xe.getMessage();
    Log.v(LOG_TAG, msg);

    StackTraceElement[] st = xe.getStackTrace();
    for (int i = 0; i<st.length; i++) { 
        msg = xe.getStackTrace()[i].toString();
        Log.v(LOG_TAG, msg);
    }
}

// creating a chat and sending messages
try {
     ChatManager chatmanager = conn1.getChatManager();
     msg = "creating chat";
     Log.v(LOG_TAG, msg);
     Chat chat = chatmanager.createChat(BUDDY_ADDRESS, new MessageListener() {

        @Override
        public void processMessage(Chat chat, Message message) {
            String msg = "incoming chat: " + message;
            Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_LONG);
            Log.v(LOG_TAG, msg);
        }
    });
    chat.sendMessage("ahoj");
} catch (XMPPException xe) {
    msg = "XMPPException during connect(): " + xe.getMessage();
    Log.v(LOG_TAG, msg);
}

(Please overlook my stupid exception handling, I’m still learning it 🙂
The connect() method should work, since it doesn’t throw an exception, in the Logcat howewer, before the “XMPP connected” message, there’s an error, and then an exception thrown by the login() method:

So the question is 🙂 if I am doing something wrong, or the project is not prepared properly for the aSmack lib to be user on android?

There’s the aSmack author’s github https://github.com/rtreffer/asmack where he mentions that build environment, which is completely chinese for me. Shall I create a new build environment? How do I do that?

Thank you for your patience!

Answer 1

It seems that my code works with an other open XMPP provider, so probably there’s no serious error neither in my code, nor in my build environment or whatever, and most probably not in the aSmack lib 🙂
I’ll play around to find out what happens when trying to connect to google, but the question is invalid for now.
