Is compiling for Android/iOS possible?

[Timothy Foster via Digitalmars-d-learn]

I'm just wondering if I made an application for Windows/Mac/Linux 
if I could get it to also work on mobile devices, or would I have 
to rewrite the application in another language to get it to work? 
If it's possible, what should I be looking at to get something 
like a "Hello World" example to show on my phone using D?
