 * sources and do not apply several adjustments that are necessary for correctness, such
 * as adjusting for VPN apps, IPv6-in-IPv4 translation, etc. These values can be used to
 * determine whether traffic is being transferred on the specific interface but are not a
 * substitute for the more accurate statistics provided by the {@link NetworkStatsManager}
 * APIs.
