MatsuriDayo/NekoBoxForAndroid ? reverse-engineered prompt

I want to build a universal proxy tool for Android that can help users get around internet censorship. It should be a single, reliable app that supports a whole bunch of different protocols, like Shadowsocks, VMess, Trojan, and VLESS, so people don't have to juggle multiple apps for their different servers.

The core of the app should be built using Kotlin and use the sing-box engine to handle the connections. A really important feature is that users should be able to import their server lists just by pasting in a subscription link from common formats. Of course, they should be able to add servers manually too. When it's active, it should work like a system-wide VPN, routing traffic for the whole device. The user interface should be clean and simple, making it easy to connect and switch between proxy configurations.
