How can i get notification on wifi signal strength change?

android, android-broadcast, android-wifi

Solution

Apparently, yes: the broadcast action is `"android.net.wifi.RSSI_CHANGED"`. See WifiManager.RSSI_CHANGED_ACTION

Have never used it personally though.

Problem

Requirement in my application is to show Wifi signal strength on wifi signal change. For a first time i am calculating the Signal strength by following code. ``` int numberOfLevels=5; WifiManager wifiManager = (WifiManager)getActivity().getSystemService(Context.WIFI_SERVICE); WifiInfo wifiInfo = wifiManager.getConnectionInfo(); int level=WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels); ``` I want to update UI frequently if wifi signal is change. Is there any broadcast available which notify me once signal strength is changed. Do you any idea How can i achieve this functionality?
