AgentWeb is an Android WebView wrapper library that provides a fluent builder API (AgentWeb.with()) to configure and manage WebView instances with features like progress indicators, file upload, JavaScript bridge, video fullscreen, URL interception, and security controls. The architecture follows a modular design with core (agentweb-core), file chooser (agentweb-filechooser), and optional third-party downloader modules. Key architectural patterns include: builder pattern for configuration, middleware/decorator pattern for WebViewClient and WebChromeClient interceptor chains, and a reflection-based decoupling approach for the file chooser to avoid mandatory dependencies. The library abstracts common WebView pain points such as lifecycle handling, memory leaks, multi-process support, and device-specific bugs (e.g., Huawei, Android 5.0/5.1). The accompanying sample app demonstrates 20+ use cases including pull-to-refresh, VasSonic pre-rendering, IPC with separate processes, and custom indicators. The codebase shows strong engineering practices with clean separation of interfaces and default implementations, though it relies on some deprecated Android APIs and reflection that may require ongoing maintenance.
