the encapsulation module is used for calling the SOMEIP library function through the JNI interface and encapsulating the SOMEIP library function into system service;
the calling module is used for calling the SOMEIP Service by utilizing the Android AIDL cross-process to generate a ServiceManager class;
the storage module is used for formulating an SOA service interface template file and storing the basic service information of the SOMEIP service input by the user;
the generating module is used for reading the basic service information of the SOMEIP service in the SOA service interface template file by using a python script, inputting the basic service information into an SOMEIP communication intermediate layer code template file and generating a java code file;
and the packaging module is used for adding the generated java code file into the Android project, and packaging the java code file with other java code files to generate an SDK (software development kit) package for use by the application layer.
9. An electronic device, comprising a memory and a processor, wherein the processor is configured to implement the steps of the method for implementing the SOMEIP communication middle layer based on the SOMEIP of the vehicle-mounted Android system SOA architecture according to any one of claims 1 to 7 when executing the computer management class program stored in the memory.
10. A computer-readable storage medium, on which a computer management class program is stored, and the computer management class program, when executed by a processor, implements the steps of the implementation method for the on-vehicle Android system SOA architecture SOMEIP communication middle layer based on claim 1-7.
