Talk to the interviewer about Binder (2) and the interviewer about binder
The interviewer said, "as you said just now, in the Android system, Binder is used for inter-process communication. How can I hear that AIDL is also used for inter-process communication? ".
In fact, AIDL is only a descriptive Language. Its full name is Android Interface Definition Language,

In Checkservice's investigation we know that the client requests the service name to ServiceManager, ServiceManager traverses the local list based on the service name, and finds a matching handle to return to the client. This handle is clearly registered by the server, what is this handle? To understand this problem first, we must study how the server and ServiceManager work together to complete a addservice operation. We start with the service-side code. Testservice.cpp:30 int main () {SP p
