WifiInfo
open class WifiInfo : TransportInfo, Parcelable
| kotlin.Any | |
| ↳ | android.net.wifi.WifiInfo |
Describes the state of any Wi-Fi connection that is active or is in the process of being set up. In the connected state, access to location sensitive fields requires the same permissions as WifiManager#getScanResults. If such access is not allowed, getSSID will return WifiManager#UNKNOWN_SSID and getBSSID will return "02:00:00:00:00:00". getApMldMacAddress() will return null. getNetworkId() will return -1. getPasspointFqdn() will return null. getPasspointProviderFriendlyName() will return null. getInformationElements() will return null. getMacAddress() will return "02:00:00:00:00:00".
