这样，ActivityManagerNative与ActivityManagerProxy相当于一个Binder的客户端而ActivityManagerService相当于Binder的服务端，这样当ActivityManagerNative调用接口方法的时候底层通过Binder driver就会将请求数据与请求传递给server端，并在server端执行具体的接口逻辑。需要注意的是Binder机制是单向的，是异步的，也就是说只能通过client端向server端传递数据与请求而不同等待服务端的返回，也无法返回，那如果SystemServer进程想向应用进程传递数据怎么办？这时候就需要重新定义一个Binder请求以SystemServer为client端，以应用进程为server端，这样就是实现了两个进程之间的双向通讯。

好了，说了这么多我们知道这里的ActivityManagerNative是ActivityManagerService在应用进程的一个client就好了，通过它就可以滴啊用ActivityManagerService的方法了。
