android - activeNetworkInfo.type is deprecated in API level 28

Question

I want to use the Connectivity manager which provide the method activeNetworkInfo.type for checking the type of network in Android. This method was deprecated in API level 28. so what is the solution to check network type in API 28. my code is :

/**
 * Check Wi Fi connectivity
 */
fun isWiFiConnected(context: Context): Boolean {
    val connManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    return connManager.activeNetworkInfo.type == ConnectivityManager.TYPE_WIFI
}

My Gradle is like :

compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
        minSdkVersion 21
        targetSdkVersion 28
    }

UPDATE

The connectivityManager.activeNetworkInfo is also deprecated in API level 29

Now we need to use ConnectivityManager.NetworkCallback API or ConnectivityManager#getNetworkCapabilities or ConnectivityManager#getLinkProperties

SAMPLE CODE USING ConnectivityManager#getNetworkCapabilities

private fun isInternetAvailable(context: Context): Boolean {
        var result = false
        val connectivityManager =
            context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            val networkCapabilities = connectivityManager.activeNetwork ?: return false
            val actNw =
                connectivityManager.getNetworkCapabilities(networkCapabilities) ?: return false
            result = when {
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                actNw.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
                else -> false
            }
        } else {
            connectivityManager.run {
                connectivityManager.activeNetworkInfo?.run {
                    result = when (type) {
                        ConnectivityManager.TYPE_WIFI -> true
                        ConnectivityManager.TYPE_MOBILE -> true
                        ConnectivityManager.TYPE_ETHERNET -> true
                        else -> false
                    }

                }
            }
        }

        return result
    }

OLD ANSWER

Yes getType() is deprecated in API level 28

Now we need to use Callers should switch to checking NetworkCapabilities.hasTransport(int)

Also getAllNetworkInfo() is deprecated in API level 29

Now we need to use getAllNetworks() instead of getNetworkInfo(android.net.Network) .

getNetworkInfo()

• Returns connection status information about a particular Network.

getAllNetworks()

• Returns an array of all Network currently tracked by the framework.

SAMPLE CODE

fun isWiFiConnected(context: Context): Boolean {
    val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
    return if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        val network = connectivityManager.activeNetwork
        val capabilities = connectivityManager.getNetworkCapabilities(network)
        capabilities != null && capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)
    } else {
        connectivityManager.activeNetworkInfo.type == ConnectivityManager.TYPE_WIFI
    }
}

        cm?.run {
            cm.getNetworkCapabilities(cm.activeNetwork)?.run {
                result = when {
                    hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                    hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                    hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET) -> true
                    else -> false
                }
            }
        }
    } else {
        cm?.run {
            cm.activeNetworkInfo?.run {
                if (type == ConnectivityManager.TYPE_WIFI) {
                    result = true
                } else if (type == ConnectivityManager.TYPE_MOBILE) {
                    result = true
