ReactContext is getting null value in Android native project.

@prashantpadhariya1137 what are you trying to do here?
Are you creating a new react native app or are you trying to integrate React native in an existing app?

In both cases, what you are doing is not the right process.
To create a new app, please run:

// Using Expo
npx create-expo-app@latest

// Using the community CLI
npx @react-native-community/cli@latest init <Name of your project> --version latest

If you want to integrate React native in an existing app, we have some docs here but they might be outdated.

I'm trying to create android library using react-native project and call that library in another android native project.

1. Created .aar file using react-native project and call react-native functions from android native.

like this

public static void sendEvent(String eventName, @javax.annotation.Nullable Object params) {
android.util.Log.d("TAG", "sendEvent: 123 R"+reactContext);

    reactContext
            .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
            .emit(eventName, params);
}

send event like this .

2. Import that .aar file in to another Android native project and call this sendEvent() method but reactcontext is getting null in my project so i need reactcontext value in Android native project.

Let me know how to get reactcontext value in android native project.

@prashantpadhariya1137 I understand.

This is not the right way to create a library for react-native: there is more boilerplate and setup needed for that.
Please follow the guide here to get started
