A communication method and system between modules of an android central control large-screen system

Abstract

The invention discloses a communication method and system between modules of an Android central control large-screen system. The method includes the following steps: an initiating module starts an AgentService, and sends a registration request to a message transfer module through the AgentService; after the message transfer module registers as the initiating module, Establish a connection with the initiating module; the initiating module sends the message data to be sent and the ID combination of the target module to the message transfer module through AgentService; after the message transfer module disassembles the ID combination of the target module, multiple target module IDs are obtained, The callback interface of the aidl type corresponding to each target module ID is obtained; the message transfer module sequentially sends the message data to be sent from the obtained callback interface of the aidl type to the corresponding target module. The invention can process and send message data more flexibly, is convenient to use, has good stability, high security, and is more intelligent, and can be widely used in the automobile communication industry.

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.
