C ++-implemented binder communication Applet

On the Internet today, I saw a small example of using C ++ to implement the binder communication, but I didn't provide a complete demo. I made it and sorted it out. I can run it on a real machine. The basic architecture is the same, and the code will not be analyzed. To analyze the Binder Mechanism, you can use it as a template. You need to add or modify functions, that is to say, it is easy to add virtual

Android binder Mechanic (1)

The binder is the core mechanism for implementing inter-process communication in the Android system. In essence, it is a specific implementation of the proxy mode, just like COM and CORBA. The basic idea of the proxy mode is that the client program obtains the proxy object of the server in some way. All the service requests to the server are sent to the proxy object, which is responsible for communication with the server. From the client perspective,
