这种以 indirect function call 的实作架构,让HAL stub 变成是一种「包含」关系,即 HAL 里包含了许许多多的 stub(代理人)。Runtime 只要说明「类型」,即 module ID,就可以取得操作函数。对于目前的HAL,可以认为Android定义了HAL层结构框架,通过几个接口访问硬件从而统一了调用方式。
Suspend function 在项目中,我们倡导使用挂起函数封装异步逻辑。在数据层 Room 或者 Retorfit 使用挂起函数风格的 API 自不必说,一些表现层逻辑也可以基于挂起函数来实现: 复制 suspendfundoShare(activity:Activity,contentBuilder:ShareContent.Builder.()->Unit):ShareResult=suspendCancellableCoroutine{cont->valshareModel...
