实现学习结论

Flutter 包的 Android 层很薄，核心业务更可能在 Dart AOT/libapp.so 与 flutter_assets；Java/smali 主要承担 plugin、广告、推送、权限桥接。
flutter_assets 有 338 个文件，适合从 asset 目录和 native strings 还原页面/素材/配置结构，而不是先追 Java Activity。
订阅/支付通常作为 Flutter plugin 或 RevenueCat/Google Billing 桥接接入，MVP 可先抽成 BillingFacade + PaywallConfig。
最早版本和 latest 差异不大，说明首版已经包含核心商业化/功能壳，早期包更多用于确认最小闭环而不是降低分析难度。

实现学习结论

Activity 数量少的工具包更像薄壳 + SDK/云配置驱动，适合学习 onboarding/paywall/权限请求/订阅链路，而不是学习复杂原生架构。
Cleaner Guru 只有少量 Activity，但权限和 RevenueCat/Appsflyer/Facebook 信号齐，学习价值在权限承诺、订阅包装和归因闭环。

实现学习结论

Activity-heavy 包把功能拆成大量原生页面/第三方 SDK Activity，入口和功能边界可优先从 Manifest Activity 命名聚类，而不是从反编译全局搜索开始。
广告 mediation Activity 占据明显空间，功能实现要把业务页面和 SDK 页面分开看，避免误把 SDK 复杂度当产品复杂度。
最早版本明显更小，适合用作初始功能 baseline；latest 增量主要反映商业化、SDK、兼容和功能扩张。
PDF 类工具的可复刻模块边界很清晰：文档入口/权限 -> 文件列表 -> 阅读器 -> 编辑/扫描/转换 -> paywall/广告；Activity 命名是最直接的功能路线图。
