Networkutils Class

I want to import NetworkUtils. Following command does not work. import android.net.NetworkUtils; Other classes like WifiInfo can be imported. Somewhere, I found it answered that

Solution 1:

The class is not part of the SDK, this may be improved in future SDK releases : https://groups.google.com/forum/?fromgroups#!topic/android-developers/9Ux2zCqCMOA
