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

Question

我通过Facebook指南集成了与Android工作室现有应用程序的原生反应: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:找不到变量:__ fbBatchedBridge

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了.

错误日志如下:

java.lang.RuntimeException: java.util.concurrent.ExecutionException: com.facebook.react.bridge.JSExecutionException: ReferenceError: Can't find variable: __fbBatchedBridge (<unknown file>:1)

我有同样的问题。事实证明，从react-native v0.21左右开始，如果你的服务器没有运行，应用程序将会崩溃（之前它显示了一个红色错误页面，但仍然运行）。只需首先启动您的服务器：

npm start

那么你的应用程序应该可以工作。
