Android系统进程间通信（IPC）机制Binder中的Client获得Server远程接口过程源代码分析(2)

注意，这里的参数reply = 0，表示这是一个BC_TRANSACTION命令。前面我们提到，传给驱动程序的handle值为0，即这里的tr->target.handle = 0，表示请求的目标Binde...

Android系统在新进程中启动自定义服务过程（startService）的原理分析（上）

在编写Android应用程序时，我们一般将一些计算型的逻辑放在一个独立的进程来处理，这样主进程仍然可以流畅地响应界面事件，提高用户体验。Android系统为我们提供了一个Service类，我们可以实现一个以Service为基类的服务子类，在里面实现自己的计算型逻辑，然后在主进程通过startServ...

Android系统进程间通信（IPC）机制Binder中的Client获得Server远程接口过程源代码分析(3)

注意，这里的status参数为0。从这里可以看出，binder_send_reply告诉Binder驱动程序执行BC_FREE_BUFFER和BC_REPLY命令，前者释放之前在binder_transaction分配的空间，地址为buffer_to_free，buffer_to_fr...

Android系统进程间通信（IPC）机制Binder中的Client获得Server远程接口过程源代码分析

在上一篇文章中，我们分析了Android系统进程间通信机制Binder中的Server在启动过程使用Service Manager的addService接口把自己添加到Service Manager守护过程中接受管理。在这一篇文章中，我们将深入到Binder驱动程序源代码去分析Client是如何通过...
