Example 30 with NetworkAgentInfo

the class ConnectivityService method getDefaultNetworkCapabilitiesForUser.

    // the array.

    // network connection, so that's the only network returned.
    //
    // With a VPN in force, some app traffic may go into the VPN, and thus
    // over whatever underlying networks the VPN specifies, while other app
    // traffic may go over the system default network (e.g.: a split-tunnel
    // VPN, or an app disallowed by the VPN), so the set of networks
    // returned includes the VPN's underlying networks and the system
    // default.
