android - React Native 与现有应用程序集成崩溃 : "Can' t find variable: __fbBatchedBridge"

Question

我通过 Facebook 指南将 React Native 与 Android Studio 中的现有应用集成:http://facebook.github.io/react-native/docs/embedded-app-android.html#content

我发现“Can't find variable: __fbBatchedBridge”的错误可以通过设置dev菜单来解决。就像ReferenceError: Can't find variable: __fbBatchedBridge

但我的问题是我在现有应用程序的 Activity 中显示了 React Native 页面，当使用 React Native View 启动 Activity 时它崩溃了。

错误日志如下:

我遇到了同样的问题。结果表明，从 react-native v0.21 左右开始，如果您的服务器未运行，应用程序将崩溃(之前它显示红色错误页面但仍在运行)。只需先启动您的服务器:

npm start

那么您的应用应该可以运行。
