Video containers not visible on Android when using Crosswalk

Hi,

The plugin works perfectly on both iOS and Android, but after adding Crosswalk I can't see the video containers anymore. I do hear sound, and on the other client the video is being visible, just not on the phone.

I had the following error:

`E/AndroidRuntime(12487): java.lang.ClassCastException: org.crosswalk.engine.XWalkCordovaView cannot be cast to android.webkit.WebView

So i replaced the (WebView) casts to XWalkView, but that doesnt help. Maybe it's being added outside the screen or under everything?

Anyone familiar with this?
