     binding.webView.setWebViewClient(new WebViewClient() {
         public boolean shouldOverrideUrlLoading(WebView view, String url) {
             view.loadUrl(url);
             return true;
         }

         @Override
         public void onPageStarted(WebView view, String url, Bitmap favicon) {
             super.onPageStarted(view, url, favicon);
         }

         @Override
         public void onPageFinished(WebView view, String url) {
             super.onPageFinished(view, url);
         }
     }
    );

    binding.webView.getSettings().setJavaScriptEnabled(true);
    binding.webView.getSettings().setBuiltInZoomControls(true);
    binding.webView.getSettings().setDisplayZoomControls(false);
    binding.webView.getSettings().setAppCacheMaxSize( 5 * 1024 * 1024 );
    binding.webView.getSettings().setAppCachePath( getActivity().getApplicationContext().getCacheDir().getAbsolutePath() );
    binding.webView.getSettings().setAllowFileAccess( true );
    binding.webView.getSettings().setAppCacheEnabled( true );
    binding.webView.getSettings().setCacheMode( WebSettings.LOAD_DEFAULT );
    if ( !ConnectivityStatus.Companion.isConnected(getContext()) ) { // loading offline
        binding.webView.getSettings().setCacheMode( WebSettings.LOAD_CACHE_ELSE_NETWORK );
    }
    binding.webView.loadUrl(this.url);
