Interface encapsulation method and system achieving Android JNI reflection

Abstract

The invention discloses an interface encapsulation method and system achieving Android JNI reflection, and relates to the technical field of JNI development of an Android system. The method comprises the steps that function set of a Reflect module is completed at first, and a corresponding function interface is formed through encapsulation so as to be provided for a Field module, a Method module and a Class module of a subsequent Native layer for calling; function set of the Field module and Method module of the Native layer is completed, and corresponding function interfaces are formed through encapsulation; at last, function set of a Class module of the Native layer is completed, and a corresponding function interface is formed through encapsulation. According to the interface encapsulation method, the class, object and function of a corresponding Java layer are obtained through a corresponding reflection function of a reflecting Java layer, encapsulation is conducted, it is guaranteed that the Native layer and the Java layer have the same calling mode, more simplified interfaces are provided, debugging is convenient, and various problems of Naive primitive reflexes are solved.

Description

technical field [0001] The invention relates to the technical field of JNI (Java Native Interface, Java local interface) development of the Android system, specifically an interface encapsulation method and system for realizing Android JNI reflection. Background technique [0002] JNI (Java Native Interface) is a programming framework that enables Java programs running on the Java virtual machine to call or be called programs written in other languages ​​(C, C++ or assembly language, etc.) specific to the local hardware and operating system. [0003] At present, in the development process of Android JNI, the Native layer (local language layer, because the Android system is based on the linux kernel, so here the Native layer represents the C / C++ language) is often used to communicate with the code and functions of the Java layer, and the Native layer Layer calls, access to Java layer objects or functions need to be obtained through reflection (in computer science, reflection ...

AI Technical Summary

Problems solved by technology

[0004] 1. The call is complicated, the amount of code is too large, and there are a lot of repeated codes;

[0005] 2. It is difficult to write the interface, and it is necessary to write its function signature for each different function, and the function signature is very easy to write errors;

[0006] 3. Difficult to debug, no way to directly locate the problem
