研究方向
首先根據連結的 repro 重現問題，並將 example/index.js 中的 AppRegistry 結果與 library wrapper 中的結果進行比較。檢查 create-react-native-library 的 turbo-module setup 如何解析 React Native，接著驗證透過該函式庫進行的 headless 工作註冊能在沒有重複 React Native 實例的情況下正常運作。
由索引模型根據 Issue 內容生成。
描述
Description
Hi!
I'm trying to create a wrapper around the AppRegistry.registerHeadlessTask function in my library like this:
export function setBackgroundMessageHandler(handler: BackgroundMessageHandler) {
AppRegistry.registerHeadlessTask('MediaControlsHeadlessTask', () => handler);
}
And this is in the example/index,js:
setBackgroundMessageHandler(require('./src/handler'));
This results in the following errors:
E Invariant Violation: "MediaControlsExample" has not been registered. This can happen if:
* Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it, and restart it in the current project.
* A module failed to load due to an error, and `AppRegistry.registerComponent` wasn't called., js engine: hermes
E ExceptionsManager should be set up after React DevTools to avoid console.error arguments mutation
E TypeError: property is not writable, js engine: hermes
E TypeError: Cannot read property 'default' of undefined, js engine: hermes
Calling AppRegistry.registerHeadlessTask in the example/index.js directly works. It seems like AppRegistry points to two react-native instances?! E.g. when printing AppRegistry.getAppKeys(), I get different results in the example/index.js and the library.
