This is not a trivial task, not even slightly. Android is not like Windows in most respects, so you need to learn a new environment.
You can do it - Xamarin supports VB, and is included in VS2015 (incl. the Community edition).
But...I've just started with it and it took me two days to the the emulator running to execute "Hello World!". And all the documentation I've seen so far is in C#, including the free MS Press book from Charles Petzold:
Creating Mobile Apps with Xamarin.Forms Book First Edition - Xamarin[
^] - I'm very tempted to say that if you are moving to Android it might be worth moving to C# first (pretty simple provided you only ever used .NET VB and ignored all the horrible legacy stuff) and then starting on the Petzold book to learn how to code for Andorid (and iOS, and Windows Phone all at the same time).
If you are an experienced developer in VB, it shouldn't take you more than a few days to learn C# - it's a pretty simple language if you already know the .NET framework stuff.
