React Native app - crash/close on startup on Android 8 real device

问题

I have a React Native project (not Expo) initialized with react native init myapp. I can run this application on Emulator and Real Device with Android 5, but cannot run the app on my Android Mobile with Android 8.

Here's the 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",

    "iso-639-1": "^2.0.3",
    "jsrsasign": "^8.0.12",
    "moment": "^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/"
    ]
  }
}

I've tested it on Genymotion emulator with Android 5 and on a real LG device with Android 5 too and everything works fine.

But lately, I tried to run this project on an Honor 8X device with Android 8. But the application will be closed without any error just after getting JS Bundle from Metro!

Run command: react-native run-android

It's the log from react-native log-android:

--------- beginning of crash
--------- beginning of system

03-05 23:29:32.642  5513  5617 D ReactNative: ReactInstanceManager.createReactContext()

Just after the last line appears, the application will be closed on the device!

Also, I gave all of the permissions to the app, including Draw on other apps, Storage permission and also excluded it from Battery Saver...

Here's the Metro Bundler output (which looks fine):

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"

I tried to run a Hello World application on my Honor 8X device and it runs successfully, so I think there's no problem with device and Android...
Also considering that myapp runs successfully on Emulator and Device with Android 5, I'm completely confused... Maby there's a problem with one of Dependencies

回答1:

Did you try to clear the cache? Usually with something like this:

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

But you probably need to remove only the metro and haste map cache. Sorry if you already tried that.

回答2:

i faced the same issue with xiomi and realm.

Started testing on moto device worked fine.

It looks like v0.58.0 of react-native isn't compatible/ breaks something in realm as of now; a temporary solution will be to initialize your RN project using v0.57.8

Steps: react-native init --version="react-native@0.57.8" projectName cd projectName npm install realm --save react-native link

And it should work
