native-module | This project features example native code | Runtime Evironment library

I created a node project and for a specific function, I need to create a custom native C-module. I created a Hello World project and moved it into a sub directory of my node project (called my-native-module). It contains the bindings.gyp, the hello-world.c, etc.

How can I now embed this into the project itself without making it an external project? How would I compile this? Is there a specific npm command for this?

Here is the current directory structure of my project, with the native-module inside

Please HELP!!

I'm working on an app in react-native that involves using a native Calendar module. I'm trying to register this module with react native and I keep getting this error.

This is how I've registered the module in MainApplication.java:

I've tried following this guide 10 times today: https://reactnative.dev/docs/native-modules-android

I just tried on a clean project following the guidelines exactly. No matter what I do I always get

I have built a react native library module (with RN 0.63). This module depends on some thirdparty SDKs. When integrated with Android (using .aar files) it works just fine. In case of iOS, I have been able to get the library module working without the SDK (using swift hence with the bridging header). On adding the SDK, I am getting errors such as .h is not avaialble.

This is my directory My directory structure:

I would like to use onRequestPermissionsResult in a native Android module, that can be imported into a React Native project.

The permission handling needs to happen in the module - so PermissionsAndroid or changing the project MainActivity won't work. For the similar onActivityResult there is a way to create and add a listener to the ReactApplicationContext.

Is there a way to do this for onRequestPermissionsResult?

Edit: Added native module code to show what I'm trying to do:

my question might be a little bit silly or ambiguous since I am fairly new to react native.

I'm trying to use the following repository for my react-native project https://github.com/smekalka/react-native-universal-pedometer. I have noticed that the repo is implemented in .java with platform folder unlike the regular .js or .ts files I used to see. Is this repository considered native module as react native doc describe?

Or in general how I can tell the whatever lib I am using is a native module.

The project is previously tested are under the support of expo-cli. I experienced the error null is not n object while using this repo. If so, I am probably going to eject the expo-cli and rewrite my code so I can use and even create own native-module for full control, some core implementations that written in other languages or expo-cli does not support.

I'm starting with React Native development and I encountered an issue in the very beginning. When trying to run my app I get errors:

Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)
Unhandled JS Exception: Invariant Violation: Native module cannot be null.
Unhandled JS Exception: Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)

My App.js:

I'm trying to build a native module to use AVFoundation. I need to write a function in Swift that returns a value to javascript, so I have followed the instructions on Exporting Swift.

Here are my 3 resulting files:

MediaManager.swift

I am following Native Module documentation for android: https://facebook.github.io/react-native/docs/native-modules-android.html#docsNav

My package currently looks like this
