9 JavaScript APIs accessing Device Hardware
Thanks!
Very useful!
One thing to note about the geolocation API is that it'll usually pop up a big "Do You Want To Reveal Your Location?" popup to the user, so you'll want to be aware of that and work around it.
battery.level has obvious applications for anyone pushing cleaner apps! I didn't know about that one - off to test...
Update having tested it - the various HTML5 battery APIs appear to be somewhat unstable. Use with caution and check what they work on first - or set your tracking up to tell you if they throw an error code. Still very useful in some circumstances!
Great carumen, thanks for this details.
Anyone tested the Device Light API ?
Appears to be Firefox Mobile only from my quick test just now.
