How can I get current network type? I found tis solution:

val info = connectivityManager.activeNetworkInfo
if (info == null || !info.isConnected()) return "-" // not connected
if (info.getType() == ConnectivityManager.TYPE_WIFI) return "WIFI"
if (info.getType() == ConnectivityManager.TYPE_MOBILE) {
    val networkType: Int = info.getSubtype()
    return when (networkType) {
                    TelephonyManager.NETWORK_TYPE_GPRS,
                    TelephonyManager.NETWORK_TYPE_EDGE,
                    TelephonyManager.NETWORK_TYPE_CDMA,
                    TelephonyManager.NETWORK_TYPE_1xRTT,
                    TelephonyManager.NETWORK_TYPE_IDEN,
                    TelephonyManager.NETWORK_TYPE_GSM -> "2G"
                    TelephonyManager.NETWORK_TYPE_UMTS,
                    TelephonyManager.NETWORK_TYPE_EVDO_0,
                    TelephonyManager.NETWORK_TYPE_EVDO_A,
                    TelephonyManager.NETWORK_TYPE_HSDPA,
                    TelephonyManager.NETWORK_TYPE_HSUPA,
                    TelephonyManager.NETWORK_TYPE_HSPA,
                    TelephonyManager.NETWORK_TYPE_EVDO_B,
                    TelephonyManager.NETWORK_TYPE_EHRPD,
                    TelephonyManager.NETWORK_TYPE_HSPAP,
                    TelephonyManager.NETWORK_TYPE_TD_SCDMA -> "3G"
                    TelephonyManager.NETWORK_TYPE_LTE,
                    TelephonyManager.NETWORK_TYPE_IWLAN, 19 -> "4G"
                    TelephonyManager.NETWORK_TYPE_NR -> "5G"
                    else -> "?"
    }
}
return "?"

But it all marked as deprecated. Screenshot: enter image description here

NetworkInfo class was deprecated in API 29. So you need to replace the deprecated methods with those mentioned in their notes.

You can use this method for newer API levels:

fun getNetwork(): String {
    val connectivityManager =
        context.getSystemService(CONNECTIVITY_SERVICE) as ConnectivityManager
    val nw = connectivityManager.activeNetwork ?: return "-"
    val actNw = connectivityManager.getNetworkCapabilities(nw) ?: return "-"
    when {
        actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> return "WIFI"
        actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> return "ETHERNET"
        actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> {
            val tm = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
            when (tm.dataNetworkType) {
                TelephonyManager.NETWORK_TYPE_GPRS,
                TelephonyManager.NETWORK_TYPE_EDGE,
                TelephonyManager.NETWORK_TYPE_CDMA,
                TelephonyManager.NETWORK_TYPE_1xRTT,
                TelephonyManager.NETWORK_TYPE_IDEN,
                TelephonyManager.NETWORK_TYPE_GSM -> return "2G"
                TelephonyManager.NETWORK_TYPE_UMTS,
                TelephonyManager.NETWORK_TYPE_EVDO_0,
                TelephonyManager.NETWORK_TYPE_EVDO_A,
                TelephonyManager.NETWORK_TYPE_HSDPA,
                TelephonyManager.NETWORK_TYPE_HSUPA,
                TelephonyManager.NETWORK_TYPE_HSPA,
                TelephonyManager.NETWORK_TYPE_EVDO_B,
                TelephonyManager.NETWORK_TYPE_EHRPD,
                TelephonyManager.NETWORK_TYPE_HSPAP,
                TelephonyManager.NETWORK_TYPE_TD_SCDMA -> return "3G"
                TelephonyManager.NETWORK_TYPE_LTE,
                TelephonyManager.NETWORK_TYPE_IWLAN, 19 -> return "4G"
                TelephonyManager.NETWORK_TYPE_NR -> return "5G"
                else -> return "?"
            }
        }
        else -> return "?"
    }
}
