            return false;

    public class OneFragment extends Fragment{

    public OneFragment() {

    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.fragment_one, container, false);
        WebView heroespage = (WebView) rootView.findViewById(R.id.webview);

        WebSettings webSettings = heroespage.getSettings();

        if(CheckNetwork.isInternetAvailable(OneFragment.this)) //returns true if internet available
        {
            webSettings.setJavaScriptEnabled(true);
        heroespage.loadUrl("http://google.com/");

        return rootView;
    }
    else
    {
        Toast.makeText(OneFragment.this, "No Internet Connection", 1000).show();
