The problem, as I believe has been repeatedly explained, is that you
don't really have any idea whether the connection is metered. Yes you
may be trying to guess by considering things like 3G connections as
metered but that is an extremely poor proxy for whether a connection is
It's not something that can be tied to connection types anyway. A wifi
interface might be unmetered if I'm at home but metered if I'm in a cafe
or hotel. An ethernet interface might be metered at certain times of day
and not at others.
The idea that you can programatically determine, using a simple
heuristic, if a connection will be metered is just nonsense.
One of the bugs has a note I was not aware of before: there's actually
a DHCP value that can be sent by the server to denote a metered
connection. If that's actually widely respected, and set by phone wifi
AP applications and the like, it could be pretty accurate. Not perfect,
but better than heuristics. I've no idea how widely it's used in the
real world, though.
