How to get Network Info - Android

This is my code below:

@SuppressWarnings("BooleanMethodIsAlwaysInverted")
private boolean isNetworkConnected() {
    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    return cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isConnected();
}

When I run the above code, I am getting a Deprecated warning saying that getActiveNetworkInfo and isConnected methods are deprecated.

I don't want to continue this code for any longer. What are some of the alternatives of the above code?

Can someone please help me? Thanks in Advance

Below is my code which I use in my application to check if device is connected to network. It does not contain any deprecated code as of now.

Kotlin

private fun isInternetAvailable(): Boolean {
    var result = false
    val connectivityManager = applicationContext.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager?
    connectivityManager?.let {
        it.getNetworkCapabilities(connectivityManager.activeNetwork)?.apply {
            result = when {
                hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> true
                hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> true
                else -> false
            }
        }
    }
    return result
}

Java

public static boolean isInternetAvailable(Context context) {
    boolean result = false;
    ConnectivityManager connectivityManager = (ConnectivityManager) context.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivityManager != null) {
        NetworkCapabilities networkCapabilities = connectivityManager.getNetworkCapabilities(connectivityManager.getActiveNetwork());
        if (networkCapabilities != null) {
            if (networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {
                result = true;
            } else if (networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {
                result = true;
            } else {
                result = false;
            }
        }
    }
    return result;
}
