Fragment keeps crashing when Bundle is in use

Question

The webFragment.xml keeps crashing when i tried to use a url that provided from MenuFragment.xml. i tried the below methods but no luck. here is the MenuFragment code

MenuFragment.xml

 Bundle bundle = new Bundle();
String url = "http://www.google.com"
            bundle.putString("webUrl", url);
            WebsFragment websFragment = new WebsFragment();
            websFragment.setArguments(bundle);
            getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.mainView, websFragment).commit();

WebFragment.xml

Bundle bundle = this.getArguments();
siteUrl = bundle.getString("webUrl");
