[Iazzetta]

I trying to build a WebView of my website and slideoutjs give me a black screen.
When I click (JUST IN SLIDEOUTJS) appear a black screen.

I enable javascript and dom storage to work with angular too, but not solve.

view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setDomStorageEnabled(true);
