React Native Android：发布版本一直在崩溃

Question

我是原生反应的新手——事实上，我对一般的应用程序开发很陌生。我正在尝试在 Android 模拟器上运行发布版本，但应用程序一直在崩溃。

调试版本运行没有任何问题，在 iOS 上同样的发布版本运行完美。

这是我所做的：

1.清理构建文件夹

2.在android/app/src/main/assets创建index.android.bundle

3.创建发布APK文件

4.在安卓模拟器上运行，但一直崩溃。

我在这里迷路了。有人可以帮忙告诉我哪里可能出错了吗？

这是由 android/app/build.gradle 提供的：

这是来自 adb logcat 的错误日志：

Answer 1

您的错误日志中的问题似乎与此有关...

React-Native :java.lang.UnsatisfiedLinkError: couldn't find DSO to load: libhermes.so

Answer 2

从 android/app 打开 Build.gradle。

将 enableProguardInReleaseBuilds 更改为 false，

def enableProguardInReleaseBuilds = false

清理 gradle 并尝试
