I already have a custom Android browser app — everything is working perfectly, both design and core functions. Now I want to add a smart auto-proxy system using my VPS server. The idea is simple: Normal websites will load directly (no proxy). If any website is blocked or restricted in a region, the app will automatically detect it and load it through my VPS proxy — without showing any error page to the user. Your job will be to: Set up the proxy on my VPS (HTTP/SOCKS or custom API). Integrate the smart detection + auto-proxy switch system into my existing app. Make sure browsing speed stays fast for normal sites. Everything else in the app is ready — I just need this proxy system integrated and working smoothly. If you’ve done any similar project (browser + proxy integration), please share examples or experience. I’m ready to start immediately.
