Method and system for communication between modules of Android central control large screen system

Abstract

The invention discloses a method and system for communication between modules of an Android central control large screen system. The method comprises the steps that a starting module initiates AgentService, registering requests are transmitted to a message transferring module through the AgentService, and after registration is conducted for the starting module by the message transferring module, the connection with the starting module is established; to-be-transmitted message data and the ID combination of target modules are transmitted to the message transferring module through the AgentService; after disassembly of the ID combination of the target modules is conducted by the message transferring module, the ID of multiple target modules is obtained, and corresponding aidl type callback interfaces of the ID of each target module are obtained; the to-be-transmitted message data is sequentially transmitted to the corresponding target modules from the obtained aidl type callback interfaces. According to the method, message data can be processed and transmitted more flexibly, the use is convenient, the stability is good and the safety is high, and the method is more intelligent and can be extensively applied to industries of automobile communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication method and system between modules of an Android central control large-screen system. Background technique [0002] The modules or processes of the Android central control large-screen system often need to communicate, such as data transmission, command transmission, status notification, etc. At present, the communication methods between the modules of the Android central control large-screen system mainly include the broadcast communication method and the aidl communication method. The broadcast communication method is to send communication data to all other modules, which is not targeted, the broadcast object is uncontrollable, and the broadcast communication result is also unknown, and the stability is poor. The aidl communication method is relatively complicated, and the development is difficult. Moreover, there are many loopholes in the direct communic...

AI Technical Summary

Problems solved by technology

The broadcast communication method is to send communication data to all other modules, which is not targeted, the broadcast object is uncontrollable, and the broadcast communication result is also unknown, and the stability is poor

The aidl communication method is more complicated, and the development is more difficult. Moreover, the modules communicate directly through the aidl communication method, and there are still many loopholes, which cannot guarantee safe communication.

In general, there are problems such as inconvenient use, poor message fault tolerance, poor stability, and insecurity in the communication between modules of the Android central control large-screen system.
