I already have a working Android browser app built with WebView. I need one feature update: Detect when a website is blocked (DNS error, timeout, 403/451, etc.). Normal websites should open directly. Blocked websites should automatically reload through my proxy API. I want the proxy API URL to be fully dynamic. The app must load the API link from my admin panel (JSON/Firebase) so I can change the proxy anytime without updating the app. The browser should support two proxies: Primary: Cloudflare Workers proxy URL Secondary: My own custom proxy URL If the primary fails, it should fall back to the secondary. You only need to update the WebView logic + integrate the dynamic API loading. Clean and documented code is required. Looking for someone experienced with Android WebView / custom browser development.
