Abstract

The embodiment of the invention discloses a vehicle machine application communication method and device, equipment and a medium. The method comprises the following steps: receiving a source instruction sent by a sender vehicle machine application through a pre-created system service, obtaining a domain name list in the system service, determining a receiver vehicle machine application corresponding to the source instruction based on the domain name list, and forwarding the source instruction to the receiver vehicle machine application through the system service. According to the invention, communication among the vehicle-mounted terminal applications based on the system service is realized, direct communication among the vehicle-mounted terminal applications is not needed, function decoupling among the vehicle-mounted terminal applications is further realized, and the workload and complexity of vehicle-mounted terminal application communication engineering are reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of intelligent networked vehicle-machine application communication, and in particular, to a vehicle-machine application communication method, device, equipment, and medium. Background technique [0002] In the prior art, if an in-vehicle application A wants to call a function of another in-vehicle application B, the two in-vehicle applications communicate through AIDL (Android Interface Definition Language, Android Interface Definition Language) cross-process. Specifically, the called application B needs to provide an aar-type functional interface library for the integration of the calling application A. Therefore, this will make the coupling between the two applications stronger; if there are multiple applications that depend on the calling application B, the volume of the aar library of application B may become larger, and the volume of each application after integrating the aar library will al...
