Firewall

⭐ Firewall allows you to block apps from accessing the Internet without root requirement.

⭕ Firewall uses the Android VpnService to route traffic to itself, the apps access the Internet will be filtered on-device instead of on a server.

⭕ The reason VpnService is needed:
- Users can allow/block the apps access the Internet, the technical for this solution is using VpnService for control the Internet access
- Firewall uses the Android VpnService to block the Internet access for apps on device
- Internet access will be filtered or block on-device instead of on a server
- We do not use VpnService to route traffic to any server, VpnService just only locally on-device to block app from access the Internet
