ClassDefNotFoundException using FacebookSDK

Question

我正在使用Facebook sdk开发一个应用程序，现在我正在将Facebook登录集成到我的应用程序中。我的问题是在我的集成活动初始化时出现NoClassDefFoundError。

有logcat输出:

这是我的活动:

public class ActivityIntegracao extends ActionBarActivity {
private IntegracaoFragment integracaoFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_integracao);
    if (savedInstanceState == null) {
        integracaoFragment = new IntegracaoFragment();
        getSupportFragmentManager().beginTransaction().add(R.id.container, integracaoFragment).commit();
    } else {
        integracaoFragment = (IntegracaoFragment) getSupportFragmentManager()
                .findFragmentById(R.id.container);
    }
}
public static class IntegracaoFragment extends Fragment {

        }
    };
    public void onCreate(Bundle savedInstanceState) {

    @Override

        LoginButton authButton = (LoginButton) rootView.findViewById(R.id.authButton);
        authButton.setFragment(this);
        TuntzMeApplication.instance().setFacebookLoginButton(authButton);
        return rootView;
    }
    @Override
    public void onResume() {
        super.onResume();
        Session session = Session.getActiveSession();
        if (session != null &&
               (session.isOpened() || session.isClosed()) ) {
            onSessionStateChange(session, session.getState(), null);
        }
        uiHelper.onResume();
    }

        uiHelper.onDestroy();
    }
    @Override

        super.onSaveInstanceState(outState);
        uiHelper.onSaveInstanceState(outState);
    }
    private void onSessionStateChange(Session session, SessionState state, Exception exception) {
        if (state.isOpened()) {
            // Abrir activity map
            Log.i(TAG, "Logged in...");
        } else if (state.isClosed()) {
            Log.i(TAG, "Logged out...");
        }
    }
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_sincronizacao, menu);
    return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}

谢谢。

我已经解决了这个问题，问题是我的构建补丁，似乎我不小心手动添加FacebookSDK到Java BuildPath，这是导致问题的原因。谢谢大家
