Class Overview

Class that provides network traffic statistics. These statistics include bytes transmitted and received and network packets transmitted and received, over all interfaces, over the mobile interface, and on a per-UID basis.

These statistics may not be available on all platforms. If the statistics are not supported by this device, UNSUPPORTED will be returned.
