I don't see anything in that which says it detects wifi tethering.
'capture portal detection' is something else, and exposing whether a
connection is metered or not through the API is nice, but doesn't mean
the information it exposes is actually *correct* or has changed in any
way.
I'm not saying it's *not* in 1.0.6, just that that text doesn't seem to
say it is. :)
Ekhm, let me cite a bullet point straight from this post:
#v+
– We now expose information on whether a particular connection is metered. It’s
intended for tools like package managers that like pre-fetch large amount of
data to be able to avoid increasing your Mobile connectivity bills.
#v-
It's pretty clear, isn't it? It's not hard technically, DHCP client
have to watch for ANDROID_METERED in option 43 and pass thath information
further up the stack.
