Question

我正在尝试使用react-native和firebase构建一个应用程序，并且在此过程中遇到了相当多的安装问题。目前，我的问题是应用程序在启动后立即崩溃，在安装后的第一次启动（调试或释放模式）。一旦被杀死并重新开始，它就能正常工作。

日志中似乎没有记录特定错误。使用日志消息来缩小崩溃点，它似乎是：

Firebase.auth().signInAnonymouslyAndRetrieveData()或
doc_ref.get()其中doc_ref是Firebase.firestore().collection("profiles").doc(instance_id)

取决于通话顺序。

在上面，“开始”意味着做

任一
- react-native run-android
或
- cd android＆amp;＆amp; ./gradlew assembleRelease
- cd ..
- react-native run-android --variant = release

如果尚未安装应用程序，请执行以上任一操作导致其启动并立即崩溃，但随后会显示在手机的已安装应用程序列表中。安装应用程序后重复上述操作会使其按预期工作。

任何帮助都会非常感激！

你读过这个吗？

＆＃34;如果GoogleService-Info.plist未在XCode中注册，则您的应用会在启动后立即崩溃。＆＃34;

阅读＆＃39; IOS故障排除＆＃39; https://rnfirebase.io/docs/v4.2.x/troubleshooting/ios

Answer 2

我对RN v0.55.4有类似的问题
最简单的解决方案是使用upgrade guide或您的偏好方法将RN更新为v> = 0.57。
另外，如果要升级点火项目，则还需要解决不兼容问题，see here
