Android Question GPS odometer with B4Xpages

I haven't found a clear answer to this... how do I use the GPS on a non-main page with B4Xpages?
So far, I have the GPS working and giving me position updates on the main/first page. When I go to a second screen, I need the GPS to keep capturing position, so I can calculate distance and update it on the second page.
Is there an example someone that shows how to do this?

Thanks.
