Main class

class MainActivity {

    val networkInfo = connectivityManager.activeNetwork
    val capabilities = connectivityManager.getNetworkCapabilities(networkInfo)
    if (capabilities?.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) == true) {
        val wifiInfo = capabilities.transportInfo as WifiInfo
        Log.d("DEBUG", "ssid: ${wifiInfo.ssid}")
    }

    val wifiManager = context.applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
    val connectionInfo = wifiManager.connectionInfo
    Log.d("DEBUG", "ssid (deprecated) ${connectionInfo.ssid}")
}

output

ssid: <unknown ssid>
ssid (deprecated): "bingo"

How to retrieve the SSID while targeting the latest API and use the latest, non deprecated functions?

  • Have you seen: [On Oreo (8.1.0) not getting the correct Wifi SSID. It's showing though it is connected to a wifi with SSID](https://stackoverflow.com/a/54079640/295004) – Morrison Chang Nov 17 '21 at 06:05

    @MorrisonChang did some tests, but this yields to the same results... i've also updated the post because the API 26 vs 31 bit was not correct – mbmc Nov 17 '21 at 16:03
  • @mbmc Have you got solution for this? For Android 12 API level 31, I am getting with connectionInfo.ssid – BSB Jan 10 '23 at 06:15

You need to enable the device's location.
