Android 应用程序在发布版本时崩溃，但在调试版本中有效 - React-Native

我知道这是一个常见问题，但我看到的错误是不同的，这是错误

我确实构建了发布并且应用程序在启动时崩溃了我尝试使用调试构建它并运行没有错误。

该应用程序最初位于 expo 但expo eject以获取 ios 和 ZC31B32364CE19CA58FCD150A417 文件夹

Answer 1

目前，必须先导入react-native-gesture-handler才能使发布版本正常工作而不会崩溃。

在index.js的最顶部添加这一行：

import 'react-native-gesture-handler';

然后尝试再次清理并重建版本。

Answer 2

你应该把--minify =false放在android/app/build.gradle 的 extraPackagerArgs

因为如果编译器认为未使用某些类/函数/方法，可能会被忽略并且不包含在发布版本中。 在您的情况下，编译器可能没有包含 expo.modules.updates.UpdatesController 或整个 expo 库。

project.ext.react = [
    entryFile: "index.js",
    extraPackagerArgs: [ '--minify=false' ],
];

Answer 3

最近，我检测到 react native 非调试模式下的 JS 引擎与调试模式下的不同，因为在调试模式下，您的代码在 chrome V8 引擎中运行，但在非调试模式下，它在您设备中嵌入的 JavaScriptCore 中运行. 因此某些功能在非调试模式下无法正常工作，例如某些日期 function 等。

Answer 4

当我遇到这个问题时，在 release 中添加 debuggable true

buildTypes {
release {
    shrinkResources false
    debuggable true
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
    shrinkResources false
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}

我希望它可以帮助你解决棘手的问题
