Hi Developer, I am testing the Worklets Library Functionaility
That i was trying to calling a Android Native Code From Worklets Runtime Thread (I Know What i am doing, I want running Native Code outside of Main Thread)
And then when start the trigger, then it would crash.

I was asking the question for the same technology and i am testing the capability of my purpose.
Below is the details that what i want to achieve in final
Is Worklets Library Supporting Calling React Module From Android Native Java Code? #8728

And below is the source codes that how i getting crash result

React Native Code

import { scheduleOnRuntime, createWorkletRuntime } from 'react-native-worklets';
import { NativeModules } from 'react-native';

const { MyNativeModule } = NativeModules;
const backgroundRuntime = createWorkletRuntime({ name: 'heavy-worker' });

export const sortInBackground = () => {
    scheduleOnRuntime(backgroundRuntime, () => {
        'worklet';
        const startTime = Date.now();

        let result = 0;
        try {
            result = MyNativeModule.startHardwareConnection();
            console.log(`Call Native Result: ${result}`);
        } catch (e) {
            console.error('Call Native error:', e);
        }

        const sortTime = Date.now() - startTime;
        console.log(`Worker Runtime Completed: used ${sortTime}ms`);
    });
};

Research direction

Start with the createWorkletRuntime and scheduleOnRuntime entry points, then inspect the worklets and React Native native-module access path implicated by DecoratedHostObject and setPropertyValue in the crash trace. Reproduce the Android example and determine the supported behavior for calling MyNativeModule.startHardwareConnection from the runtime thread; done should mean the crash is resolved or the limitation is clearly documented.
