Cross-process communication method and device based on Android platform

Abstract

The invention relates to a cross-process communication method and device based on an Android platform. The method comprises the following steps: a first unified method in a first unified access layer of a first process makes response to a calling instruction of an arbitrary original cross-process method sent by a business layer to generate a cross-process calling request, and sends the cross-process calling request to a second process corresponding to a target original cross-process method requested for calling; a second unified method in a second unified access layer of the second process obtains an identifier and an entry parameter of the target original cross-process method according to the request; the second unified method determines the corresponding target original cross-process method according to the identifier and the entry parameter of the target original cross-process method, obtains called data according to the target original cross-process method, and returns the called data to the first unified method; and the first unified method returns the called data to the business layer, and related processing operations of the called data according to the first unified method. The scalability and the efficiency of the cross-process method are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a cross-process communication method and device based on an Android platform. Background technique [0002] For the Android system, when there are multiple processes in an application, due to the limitation of the operating system, the memory data between the processes are not interoperable. When processes need to access each other's data, cross-process communication is required, for example, by calling a cross-process method to perform cross-process data calls. [0003] However, when Android natively defines a cross-process method, it needs to be in AIDL (Android Interfacedefinition language, which is an interface description language, which is used to generate interprocess communication (IPC) between two processes on an Android device. code) file to declare the function, and then use the compiler to generate the corresponding code according to the fixed template of the funct...

AI Technical Summary

Problems solved by technology

In this way, since the native template of the Android system is fixed, if you want to uniformly modify all cross-process methods defined natively on Android (for example, add a new cache function uniformly, or add a uniformly new call speed measurement function), you need Modify the specific implementation logic of each cross-process method one by one. Obviously, the traditional cross-process method is not easy to expand
