看到篇文章讲组件化的 Android彻底组件化方案实践
觉得很好
顺带看了下maven /gradle plugin相关

Demo的依赖结构

     |basiclib|
     +--------+

basiclib

依赖通用库，如网络请求，图片加载等

basicres

文件资源/图片资源/文字资源等

componentlib

build.gradle 里包含两个task

  • 将class打成jar包
  • 把jar包复制到release

                          +--------+

IApplicationLike

模拟生命周期

  • onCreate()
  • onStop()

IComponentRouter

  • 发送uri，类Intent
  • 单例

IUIRouter

  • 注册或解注册
  • 单例

UIRouter

  • 实现类
  • List uiRouters
  • HashMap<IComponentRouter, Integer> priorities

Router

  • HashMap<String, Object> services
  • HashMap<String, IApplicationLike> components

componentservice

各个组件在此注册供root调用

每个组件在此定义一个Interface, 阐明提供的服务，并在组件内实现该interface
并于ApplicationLike中注册实现类

组件们[root / component one / component two / …]

通过gradle插件实现自动切换application或library

插件参数

  • isRegisterCompoAuto
  • applicationName
