Question

我的应用程序在本地服务器上运行正常，没有任何问题。但是，当我尝试生成Release版本时，它无法正常工作。单击图标，应用程序立即崩溃。我试图检查ViewPropTypes并在必要的地方进行更新。但是仍然有同样的问题。

这是日志：

有人可以帮我解决这个问题吗？

Answer 1

最后，我花了4天才得到答案。问题是Android将在index.android.js中包含旧版本文件。其中的代码是以前的版本，因此会产生问题。在iOS中，随着我们删除 build 文件夹的解决方法。

尝试创建需要react-native的新文件。以下是有助于解决此问题的命令。

Android：

react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

iOS：

react-native bundle --platform ios  --dev false --assets-dest ./ios --entry-file index.ios.js --bundle-output ios/main.jsbundle

Answer 2

一些调试技巧：

如果您使用的是Android，则可以使用以下命令运行Android应用的调试版本：生产包从开发设置中禁用开发包。
如果需要，还可以启用minify来查找这是否是一个减少问题。
另一个坏主意是生成生产版本并打开捆绑文件并导航到837：1752，这样您就会知道这在哪里发生。

如果可以的话，我看不到日志中的任何错误，完成日志？

Answer 3

您可以检查以下几件事：

是否启用了构建保护程序？如果是，则禁用并尝试运行并检查。您将了解确切的错误和obj详细信息。
用于调试和发布的环境是否相同？ -您尝试在null对象上调用login_type。
您可以在调用login_type的位置添加空检查并测试发布版本。
如果没有任何效果，请使用最后一个选项-集成错误提示崩溃报告。这真的是很酷的javascript库，它将提供有关崩溃的更多详细信息。

谢谢。
