Title:
INTER-PROCESS COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/111711
Kind Code:
A1
Abstract:
An inter-process communication method and an apparatus. When an access reference of a first system service is stored in a memory of an application program process, the application program reads the access reference of the first system service from the memory of the application program process. When the access reference of the first system service is not stored in the memory of the application program process, the application program obtains the access reference of the first system service from a service manager, and stores the access reference of the first system service in the memory of the application program process. Thus, when the application program accesses the access reference of the system service for the first time, the access reference of the system service is stored in the memory of the application process, and on subsequent accessing of the access reference of the system service, the access reference of the system service is directly obtained from the memory, without requiring a request to be sent to the service manager by means of Binder communication, thereby decreasing the amount of binder communication, and improving system performance.
