You have to use like this way when user press logout button you have to execute this code

  public void runTestLogout() {
    if (testLogout()) {
        logoutText.setText("Logout Tests Passed");
    } else {
        logoutText.setText("Logout Tests Failed");
    }
}



 public boolean testLogout() {
    try {
        Log.d("Tests", "Testing logout");
        String response = authenticatedFacebook.logout(this);
        Log.d("Tests", "Got logout response: *" + response + "*");
        if (!response.equals("true")) {
            return false;
        }

        Log.d("Tests", "Testing logout on logged out facebook session");
        try {
            Util.parseJson(authenticatedFacebook.logout(this));
            return false;
        } catch (FacebookError e) {
            if (e.getErrorCode() != 101 || 
                    !e.getMessage().equals("Invalid API key") ) {
                return false;
            }
        }

        Log.d("Tests", "Testing logout on unauthenticated object");
        try {
            Util.parseJson(new Facebook(APP_ID).logout(this));
            return false;
        } catch (FacebookError e) {
            if (e.getErrorCode() != 101 || 
                    !e.getMessage().equals("Invalid API key") ) {
                return false;
            }
        }

        Log.d("Tests", "All Logout Tests Passed");
        return true;
    } catch (Throwable e) {
        e.printStackTrace();
        return false;
    }
}

The main thing is

  String response = authenticatedFacebook.logout(this);

by running this code you will be logout now you can again log in and you will get empty username and password button
