URL to external sdcard files/folders?

[FF22]

I am trying to store my own "HOMEPAGE" which I call:

Tab-S.html

on my EXTERNAL sdcard.

I can do this on my BB devices using appropriate references and using the file:/// url.

I can store the file in INTERNAL memory/storage and gain access to it using the following url:

file:///sdcard/Download/Tab-S.html

But can't figure out the reference for an EXTERNAL sdcard. Is there a way or is this one of those kitkat restrictions?

Thanks in advance. Or maybe I should ask this in a more generic Android forum?

Well, I figure I would bump my question. No one has suggestions?
