Question: 一、onLooperPrepared()可以在Looper开始循环之前做一些什么样的Setup操作呢？？ 二、synchronized(this)，放在run()函数中保护Looper的获取过程，为啥要保护呢？ getLooper()中也加了synchronized(this)，为哈？ 三、在getLooper()中 需要判断mLooper是否为空，是不是说在HandlerThread执行run()方法之前，会有可能被调用getLooper()??? /* ...
java 流程驱动 框架_Android驱动学习-app调用内核驱动过程(驱动框架回顾)
weixin_35615010的博客

考研已经过去了，android驱动的学习也断了半年多了，现在重新捡起来学习，回顾一下Android驱动的大体框架。Android系统的核心是java，其有一个David虚拟机。Android-app操作硬件也相当于是java操作硬件。在Linux系统上操作硬件是通过open read write等来实现，也就是操作C库。如果java能直接调用C库中的函数，也就解决了app操作硬件的问题。下面的文章...
