Add ability to toggle "Network Notification" setting on and off.
In Android WiFi settings is "Network Notification" with subheading of "Notify me when an open network is available". I am not sure if this actually stops active scanning for open networks or merely suppresses the notification of them, but it would be nice to be able to toggle this setting and possibly save battery and/or increase security of the device in unfamiliar places. If the setting only suppresses the notification, then this idea may not be very useful.
This setting is restricted by Android, and cannot be modified by 3rd party apps such as Locale. http://developer.android.com/reference/android/provider/Settings.Secure.html
Even if this setting weren’t restricted, I don’t think it would be of much benefit. This setting simply prevents Android from notifying you of open access points. Android will still have to scan periodically, otherwise how would it know to connect to known access points?
