SImple Asmack program not working

Question

Simplest possible code:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SmackAndroid.init(this);
        // Create a connection to the jabber.org server.
        XMPPTCPConnection conn1 = new XMPPTCPConnection("xmpp-hosting.de");
        try {
            conn1.connect();
        } catch (SmackException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XMPPException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        Log.d(TAG, "Connected successfully!");

        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new PlaceholderFragment()).commit();
        }
    }

But I get a NoClassDefFound Exception at init(). I noticed there are some warnings while building the app:

[2014-06-30 08:47:51 - AsmackTest] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(jnamed$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

Seems reasonable that if I can get rid of warnings the code will work. In the log there is a suggestion to build the class from source. Unfortunately I am unable to build the asmack code: Cannot build asmack. So I am in limbo ..Where do I begun to troubleshoot?

Asmack version: asmack-android-8-4.0.0.jar
