android - Android API 31，如何获取SSID？

问题描述

清单（声明和授予的权限）

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

主班

class MainActivity {
    val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    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}")
}

输出

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

如何在针对最新 API 并使用最新的非弃用功能时检索 SSID？
