Load Native Android Interface on Unity Android

Hi Guys,
…is it possible?
I did search on this forum and google of course but i found only people asking the same thing with no clear answer.

I use Unity iOs Pro and i managed to change the AppController to load a UIWIndow made in Xcode all works just great.

I bought now an iOS Android pro licence and i need to do the same but in this platform…i’m just in panic…

Anyone can help? Some plug in to buy or maybe is even simpler?

Cheers,
Ale.
