@Override
    public boolean shouldOverrideKeyEvent(WebView view, KeyEvent event) {
      return CWVC.shouldOverrideKeyEvent(view, event);
    }
Unconventional way of adding a Javascript interface but the main reason why I took this way
is that it is working stable compared to the webview.addJavascriptInterface way.
