Getting error with SmackAndroid.init(context)

Question

I am trying to create a room using aSmack muc. I have a connect() method which connects to the xmpp server no problem (below).

public void connect() {

                ConnectionConfiguration connConfig = new ConnectionConfiguration(HOST,
        PORT, SERVICE);
        XMPPConnection connection = new XMPPConnection(connConfig);

        try {
            connection.connect();
            Log.i("XMPPChatDemoActivity",
                    "Connected to " + connection.getHost());
        } catch (XMPPException ex) {
            Log.e("XMPPChatDemoActivity",
                    "Failed to connect to " + connection.getHost());
            Log.e("XMPPChatDemoActivity", ex.toString());
            setConnection(null);
        }
        try {
            connection.login(USERNAME, PASSWORD);
            Log.i("XMPPChatDemoActivity",
                    "Logged in as " + connection.getUser());

            Presence presence = new Presence(Presence.Type.available);
            connection.sendPacket(presence);
            setConnection(connection);

        } catch (XMPPException ex) {
            Log.e("XMPPChatDemoActivity", "Failed to log in as " + USERNAME);
            Log.e("XMPPChatDemoActivity", ex.toString());
            setConnection(null);
        }
    }

However when I try to use the .create function in the createRoom method below:

                private void createRoom() {
        MultiUserChat muc = new MultiUserChat(connection,
                "name@conference.<myxmppserver>");
        try {
            if (connection != null) {
                muc.create("testroom");
                Form form = muc.getConfigurationForm();
                Form submitForm = form.createAnswerForm();
                for (Iterator fields = form.getFields(); fields.hasNext();) {
                    FormField field = (FormField) fields.next();
                    if (!FormField.TYPE_HIDDEN.equals(field.getType())
                            && field.getVariable() != null) {
                        submitForm.setDefaultAnswer(field.getVariable());
                    }
                }
                submitForm.setAnswer("muc#roomconfig_publicroom", true);
                muc.sendConfigurationForm(submitForm);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

it gives me a ClassCastException error, for which a solution is here: ClassCastException when creating MUC room for XMPP group chat using aSmack

However when I add the

            Context context = getApplicationContext();
    SmackAndroid.init(context);

to the beginning of my connect() method, I am getting this error:

java.lang.NoClassDefFoundError: org.jivesoftware.smack.SmackAndroid

But I have added the aSmack library containing the class SmackAndroid to my build path in eclipse. Not sure how to solve this problem since the class seems to be in the build path at compile time, but isn't found at runtime. Any suggestions? Thank you!

Hi, I am facing the same issue. have you got any solution? If yes please let me know. also ping me the asmack jar location. Thanks. — RQube, Aug 27 '14 at 12:30

In response to your question:

java.lang.NoClassDefFoundError: org.jivesoftware.smack.SmackAndroid

But I have added the aSmack library containing the class SmackAndroid to my build path in eclipse. Not sure how to solve this problem since the class seems to be in the build path at compile time, but isn't found at runtime. Any suggestions? Thank you!

Have you tried setting the asmack library under the properties > java build path > order and export menus? (Not only the Libraries tab) Seems to compile without that error then.
