You should add the given blow code i think in your code plugin or java script are not enabled.

WebView webView=(WebView)this.findViewById(R.id.WebView01);
Intent intent = new Intent(Intent.ACTION_VIEW);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setAllowFileAccess(true);
webView.getSettings().setPluginsEnabled(true);

I hope this is help.
