我有一个用react native init myapp初始化的React Native Project（不是EXPO）。我可以使用Android 5在模拟器和真实设备上运行此应用程序，但无法使用Android 8在我的Android Mobile上运行该应用。
这是package.json：

我已经在使用Android 5的Genymotion模拟器上对其进行了测试，并在带有Android 5的真实LG设备上进行了测试，并且一切正常。
但是最近，我试图使用Android 8上的 Honor 8x设备上运行此项目。但是，从Metro获得JS捆绑后，该应用程序将关闭，而不会出错！
- 运行命令：
react-native run-android
是react-native log-android的日志：
--------- beginning of crash
--------- beginning of system
--------- beginning of main

03-05 23:29:32.642 5513 5617 D ReactNative: ReactInstanceManager.createReactContext()
出现最后一行之后，该应用程序将在设备上关闭！
- 另外，我将所有权限授予了该应用程序，包括绘制其他应用程序，存储权限也将其排除在电池节省 ...
这是Metro Bundler输出（看起来不错）：

- 我试图在我的荣誉8X设备上运行 Hello World 应用程序成功，所以我认为设备和Android没有问题...
- 还考虑到
myapp在Android 5上成功运行在模拟器和设备上，我完全感到困惑... Maby 依赖项之一

您是否尝试清除缓存？通常与这样的东西：
rm package-lock.json
rm -rf node_modules
rm -rf $TMPDIR/metro-*
rm -rf $TMPDIR/haste-map-*
npm cache clean
npm install
npm start -- --reset-cache
，但您可能只需要删除地铁和急速地图缓存。对不起，如果您已经尝试过。
我与xiomi and Realm遇到了同样的问题。
开始在Moto设备上进行测试工作正常。
看来，v0.58.0的反应本地人不兼容/到目前为止，在领域中打破了某些东西。临时解决方案将是使用v0.57.8
初始化您的RN项目步骤：react-native init-version =" react-native@0.57.8" projectNameCD ProjectNameNPM安装领域 - 保存反应链接
它应该起作用
您应该从
更改代码def enableSeparateBuildPerCPUArchitecture = true
def enableProguardInReleaseBuilds = true
进入
def enableSeparateBuildPerCPUArchitecture = false
def enableProguardInReleaseBuilds = false
