android - Expo go 立即崩溃而没有错误消息（React Native）

问题描述

问题：

嘿 Stackoverflow。由于互联网问题，我上周只在网络模拟器中测试了我的 react native 应用程序。现在我想在Expo go，移动模拟器中尝试一下。但是一旦我连接到项目并且完全构建了 js，整个应用程序就会崩溃而没有错误消息。

我试图解决的问题：

我现在将我的手机连接到我的 Windows 电脑并运行这个 logcat 命令：adb logcat *:S ReactNative:V ReactNativeJS:V以这种方式获取错误消息。但我无法弄清楚问题是什么。

当我运行应用程序时，logcat 命令会记录下来：

10-19 13:54:39.731  9429 11453 I ReactNativeJS: Running "main" with {"initialProps":{"exp":{}},"rootTag":1}

Implement it using expo-application's androidId on Android and a storage API such as expo-secure-store on iOS and localStorage on the web. This API will be removed in SDK 44.

如果这很重要，这些是我的版本：

    "@babel/preset-env": "^7.15.8",

    "react-navigation": "^4.4.4",

  },

我希望你能帮助我。随时使用我也可以运行的另一个 logcat 命令发表评论。

解决方案

我不确定这是否有帮助，但我也遇到了 Expo Go 的稳定性问题。它们的范围从我尝试从 Snack 运行 React Native 项目时突然崩溃到无法通过启动屏幕。我之前在 Google Play 上查看了 Expo Go 的评论，发现有几个人报告了多个稳定性问题。虽然通过 Snack 在线预览运行 RN 很方便，但我想我可能需要通过 CLI 为我的设备测试它。我希望这些问题能尽快得到解决。
