VpnService is a base class for applications to extend and build their VPN solutions. It generally creates a virtual network interface, configures addresses and routing rules, and returns a file descriptor to the application. Each read from the descriptor retrieves an outgoing packet routed to the interface. Each writes to the descriptor injects an incoming packet just like it was received from the interface. The interface runs on Internet Protocol (IP), so packets are always started with IP headers. The application then completes a VPN connection by processing and exchanging packets with the remote server over a tunnel.
Letting applications intercept packets raises huge security concerns. A VPN application can easily break the network. Besides, the two of them may conflict with each other. The system takes several actions to address these issues.
