I remember some core Android team members giving me odd looks when I
referenced the android.resource Uri scheme in a previous email. I'm not
sure I would count on that scheme, as I suspect it's in a bit of a dusty
Android corner.
Moreover, while I appreciate the elegance of everything-is-a-Uri, there
is no question that different sources of data behave differently. You're
not going to want to call setImageURI() on an http:// URL, for example
-- you want to do the HTTP download in a background thread, cache the
result, etc. Technically, an HTTP Uri might work; practically, it's not
a good solution.
Hence, I'm not convinced the road you're travelin' down is necessarily
the best road.
