如何在安卓服务中获取ReactContext？

import com.facebook.react.bridge.ReactContextBaseJavaModule;
import com.facebook.react.bridge.ReactApplicationContext;

public class MyService extends Service {
    private MyModule myModule;

    @Override
    public void onCreate() {
        super.onCreate();
        myModule = new MyModule(getReactApplicationContext());
    }

    // ...

    public class MyModule extends ReactContextBaseJavaModule {
        public MyModule(ReactApplicationContext reactContext) {
            super(reactContext);
        }

        // ...
    }
}

public class MyModule extends ReactContextBaseJavaModule {
    public MyModule(ReactApplicationContext reactContext) {
        super(reactContext);
    }

    @Override
    public String getName() {
        return "MyModule";
    }

    @ReactMethod
    public void doSomething() {
        ReactContext reactContext = getReactApplicationContext();
        // 使用ReactContext进行操作
    }
}

import { NativeModules } from 'react-native';

const MyModule = NativeModules.MyModule;

MyModule.doSomething();
