几个星期以来，我一直遇到问题，我在react-native应用程序中使用react-navigation，当我在调试模式下在设备上进行测试时，我可以在屏幕之间正确导航，但是当我构建签名的apk时，导航确实不再工作了。 我尝试了一切，但没有任何效果。
我正在使用本机反应0.61.2，反应导航4.0.10
这是我的app / build.gradle文件

entryFile: "index.js",
enableHermes: false, // clean and rebuild if changing
]
apply from: "../../node_modules/react-native/react.gradle"
/**
* Set this to true to create two separate APKs instead of one:
* - An APK that only works on ARM devices
* - An APK that only works on x86 devices
* The advantage is the size of the APK is reduced by about 4MB.
* Upload all the APKs to the Play Store and people will download
* the correct one based on the CPU architecture of their device.

* The international variant includes ICU i18n library and necessary data
* allowing to use e.g. `Date.toLocaleString` and `String.localeCompare` that
* give correct results when using with locales other than en-US. Note that
* this variant is about 6MiB larger per architecture than default.

似乎他们在0.60.2的捆绑中破坏了与JS Core相关的内容-我现在正在研究类似的问题，客户端的puchdb和后端的benchdb。
32位工作良好，直到我将“ metro-react-native-babel-preset”：“ 0.56.3”更新为最新版本-即使在32位版本中，它也停止工作。 原因是在RN中，他们在调试（Chrome V8）和发行版（JSC）中使用了不同的JS引擎-这对我来说是一个相当可疑的决定。对于98％的代码，它可以工作，但是在极端情况下，我们遇到了如此怪异的问题... 我将尝试RN V8
