A VpnService implementation should receive all network traffic from the device, not just your application traffic. For this reason, there can only be ONE vpn active at a given time (either a custom impl using VpnService OR one of the stock android "legacy" VPNs). The ParcelFileDescriptor that you get in VpnService allows you to read/ write packets to/from the device. In theory you should be able to inspect these packets and analyze. As far as I know, custom VPN implementations using VpnService DO NOT show-up in the standard VPN configuration settings on the device...and you actually have to create the client UI code to activate your custom VPN as well. -Mike -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
