How to detect when user turn one wifi connection to other wifi?

Question

I have problem with WiFi connection detection. My goal is to detect when user is switching between different WiFis. I found this, but it only detects when WiFi was established. In my case I need to know when one WiFi network changed to another on phone.

once you get that notification, just check if the current wifi name is equal to previous one, and if not - the wifi network changed — Vladyslav Matviienko, May 22 '18 at 08:25
Use `NETWORK_STATE_CHANGED_ACTION` for your BroadcastReceiver. It will give you a `CONNECTED` message. Then you can check as @VladyslavMatviienko suggested. — Ben, May 22 '18 at 08:31

You can use BroadcastReceiver

public class ConnectivityReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        ConnectivityManager conMan = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = conMan.getActiveNetworkInfo();
        if(intent.getAction().equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)) {
                if(netInfo.isConnected()) {
                    WifiManager wifiManager = (WifiManager) context.getAplicationContext().getSystemService (Context.WIFI_SERVICE);
                    WifiInfo info = wifiManager.getConnectionInfo ();
                    String ssid  = info.getSSID();
                    Log.d("Wifi Connected", "Wifi name is "+ info.getSSID());
                }
        }
    }
}

@Eugen my studio recomends to use context?.applicationContext?.getSystemService(Context.WIFI_SERVICE) instead context?.getSystemService(Context.WIFI_SERVICE) – Serg Burlaka May 22 '18 at 09:14
