Android Native Code

Howdy all?  

I'm currently looking at the requirements for Prolog on Android.  

There's a thing called GNU Prolog for Java and I'm wondering what
sort of relationship it has to Gprolog (if any).  Another path 
I'm looking at is putting together a "native code" version 
of Gprolog (that is running on what Google calls the "native" cpu).

Anyone know of any attempts down this path?  

Thanks,

Dhu
