Question

我通过Facebook指南集成了与Android工作室中的现有应用程序本地反应：http://facebook.github.io/react-native/docs/embedded-app-android.html#content

我发现可以通过设置开发菜单来解决“无法找到变量：__ fbBatchedBridge”的错误。就像ReferenceError: Can't find variable: __fbBatchedBridge

一样

但我的问题是我在现有应用程序的活动中显示了React Native页面，它在使用react native视图启动活动时崩溃。

错误日志如下：

Answer 1

我遇到了同样的问题。原来作为react-native v0.21左右，如果您的服务器没有运行，应用程序将崩溃（之前它显示红色错误页面但仍然运行）。只需先启动服务器：

npm start

然后你的应用应该有用。

Answer 2

停止Google Chrome调试。为我工作

React与现有应用程序崩溃的本机集成：“找不到变量：__ fbBatchedBridge”
