Smack 4.1 SASL authentication error

Question

I am using Smack 4.1 native library for android to develop a chat application. I'm able to set a connection between my application and my server but I'm getting SmackException regarding SASL authentication while logging in.

Points to be noted.

1. There is no SASL authentication required on my server side.
2. My application is not crashing but getting the following errors which i have shown below in my log cat snnippet.

I'm using eclipse Luna and JDK version 1.7 and I have included the following libraries in the libs folder.

1. jxmpp-core-0.4.1
2. jxmpp-util-cache-0.4.1
3. minidns-0.1.1
4. smack-android-4.1.0.jar
5. smack-android-extensions-4.1.0
6. smack-core-4.1.0
7. smack-extensions-4.1.0
8. smack-im-4.1.0
9. smack-tcp-4.1.0

This is my code which I'm using to establish a connection.

XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
        configBuilder.setUsernameAndPassword(userName, pass);
        configBuilder.setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled);
        configBuilder.setResource("testServices");
        configBuilder.setServiceName(DOMAIN);
        configBuilder.setPort(PORT);
        configBuilder.setHost(DOMAIN);
        configBuilder.setDebuggerEnabled(true);

        AbstractXMPPConnection connection = new XMPPTCPConnection(
                configBuilder.build());

        /** Connecting to the server */
        try {
            connection.connect();
            Log.i(TAG, "Connected to " + connection.getHost());
        } catch (SmackException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XMPPException e) {
            Log.e(TAG, "Failed to connect to " + connection.getHost());
            Log.e(TAG, e.toString());
            e.printStackTrace();
        }

        /** LogingIn to the server */
        try {

            //SASLMechanism.PLAIN();
            //SASLAuthentication.("PLAIN", 0);

            connection.login(userName, pass);
            // connection.login();
        } catch (XMPPException e) {
            e.printStackTrace();
        } catch (SmackException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        /** LogingOut from the server */
        connection.disconnect();

This is my logcat output.

Answer 1

After struggling a lot finally i have found the solution to my problem.

I have to import the smack-sasl-provided-4.1.0.jar to get rid of this SASLAuthentication error.
