Question

我有一个用react native init myapp初始化的React Native项目（不是Expo）。我可以在具有Android 5的Emulator和Real Device上运行此应用程序，但不能在具有Android 8的Android Mobile上运行该应用程序。

这里是package.json：

{
  "name": "myapp",
  "version": "2.0.0",
  "private": true,
  "main": "lib/index.js",
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "axios": "^0.18.0",
    "formik": "^1.5.1",
    "iso-639-1": "^2.0.3",
    "jsrsasign": "^8.0.12",
    "moment": "^2.24.0",
    "moment-jalaali": "^0.8.3",
    "react": "16.6.3",
    "react-native": "0.58.6",
    "react-native-app-intro-slider": "^1.0.1",
    "react-native-document-picker": "^2.3.0",

    "react-navigation-material-bottom-tabs": "^1.0.0",
    "realm": "^2.24.0",
    "yup": "^0.26.10"
  },
  "devDependencies": {
    "babel-cli": "^6.26.0",
    "babel-core": "7.0.0-bridge.0",
    "babel-jest": "24.1.0",
    "babel-preset-flow": "^6.23.0",
    "flow-bin": "^0.86.0",
    "jest": "24.1.0",
    "metro-react-native-babel-preset": "0.53.0",
    "react-test-renderer": "16.6.3"
  },
  "jest": {
    "preset": "react-native",
    "transformIgnorePatterns": [
      "node_modules/(?!(jest-)?react-native|react-navigation|react-navigation-redux-helpers)"
    ]
  },
  "rnpm": {
    "assets": [
      "./assets/fonts/"
    ]
  }
}

我已经在带有Android 5的Genymotion模拟器和带有Android 5的真实LG设备上对其进行了测试，并且一切正常。

但是最近，我尝试在装有Android 8的 Honor 8X 设备上运行该项目。但是，从Metro获得JS Bundle之后，该应用程序将被关闭，没有任何错误！

运行命令：react-native run-android

这是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()

仅在最后一行显示之后，应用程序将在设备上关闭！

此外，我还授予了该应用程序所有的权限，包括在其他应用程序上绘制，存储权限，并且也将其从“省电模式”中排除了> ...

这是Metro Bundler的输出（看起来不错）：

Loading dependency graph, done.
 DELTA  [android, dev] ..\..\../index.js ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 100.0% (1169/1169), done.

::ffff:127.0.0.1 - - [05/Mar/2019:20:02:17 +0000] "GET /index.delta?platform=android&dev=true&minify=false HTTP/1.1" 200 - "-" "okhttp/3.12.1"

我尝试在Honor 8X设备上运行 Hello World 应用程序，并且该应用程序成功运行，所以我认为设备和Android都没有问题...
还考虑到myapp在Android 5的模拟器和设备上成功运行，我完全感到困惑……Maby依赖项之一出现了问题

Answer 1

您是否尝试清除缓存？通常是这样的：

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

但是您可能只需要删除都会和急速地图缓存。抱歉，如果您已经尝试过。

Answer 2

我在xiomi和realm上面临着同样的问题。

开始在moto设备上进行测试正常。

到目前为止，react-native v0.58.0似乎不兼容/目前已在领域中破坏了某些内容；临时解决方案是使用v0.57.8初始化您的RN项目

步骤： react-native init --version =“ react-native@0.57.8” projectName cd projectName npm install realm --save 反应本机链接

它应该可以工作

Answer 3

你应该改变你的代码

def enableSeparateBuildPerCPUArchitecture = true
def enableProguardInReleaseBuilds = true

进入

def enableSeparateBuildPerCPUArchitecture = false
def enableProguardInReleaseBuilds = false
