WifiManager wifiManager = (WifiManager) context.getApplicationContext()                .getSystemService(WIFI_SERVICE);        assert wifiManager != null;        switch (action) {            case WifiManager.NETWORK_STATE_CHANGED_ACTION:            case LocationManager.PROVIDERS_CHANGED_ACTION:                onWifiChanged(wifiManager.getConnectionInfo());                break;        }    }
