UnityPlayer inside Fragment

Hey,
I found a lot of posts via google, but no one had a solution as it seems. I want to use the UnityPlayer inside a Fragment!

My View is a simple one with a RelativeLayout and a fragment inside, the fragment calls all necessary onPause etc. on the UnityPlayer. The important part is here:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

mUnityPlayer = new UnityPlayer(getActivity());

// int glesMode = mUnityPlayer.getSettings().getInt(“gles_mode”, 1);
//boolean trueColor8888 = true;
//mUnityPlayer.init(glesMode, trueColor8888);

return mUnityPlayer.getView();
}

This doesnt work (with or without the slashes)… the fragment just stays black. The “normal” UnityPlayerNativeActivity works without problems.

The Unity Application uses Vuforia (if this is important)

have you found solution for that?
