如何从本机代码调用 C 函数? [英] How to call a C function from a react-native code?

问题描述

我使用 react-native 开发了一个小型 android 应用程序.对于它的开发，它运行良好.现在为了满足一个小需求，我们需要调用一个用C编写的库.不知道有没有办法从JavaScript调用C代码！但我还是想问大家.

I have developed a small android application using react-native. For what it was developed, it works fine. Now to accommodate a small requirement, we need to call a library written in C. I am not sure if there will be a way to call the C code from JavaScript! But I still wanted to ask you all.

有没有办法从 react-native 做到这一点?就像我想调用 C 库中的一些函数一样.如果可能的话，你能建议怎么做吗?我如何开始测试一个非常基本的设置?

Is there a way to do this from react-native? Like I want to call some functions in the C library. If this possible, could you please suggest how? How could I start to test a very basic setup?

推荐答案

你将不得不写一些原生代码，搜索如何在 Android 上调用 C 库，然后寻找 react native 方式来链接原生代码使用 js 调用.

You are going to have to write some native code, search for how to call a C lib on Android, then look for react native way to link a native code with a js call.
