Hi guys I'd like to have my application receive a notification as new Wifi networks are detected. I realize there's a startScan() method in WifiManager that will run a scan of available networks, but I'm wondering if this info is broadcast from the Android OS itself on a regular basis? Ideally, I'd like my app to receive notification as new Wifi networks become available without having to programatically run a startScan at regular intervals. Is this possible? If not, I'll kick off a new thread and run startScan() at regular intervals. Can somebody make a recommendation as to how frequently this should be done without sucking the battery dry too quickly. Again, ideally my app will be notified as soon as a Wifi network becomes available so I'm considering running the scan something like every 30 seconds to a minute. Thoughts?
