2020-10-09 15:39:08.434 14910-14976/? E/ReactNativeJS: Error: [@RNC/AsyncStorage]: NativeModule: AsyncStorage is null.

To fix this issue try these steps:

  • Run `react-native link @react-native-community/async-storage` in the project root.

  • Rebuild and restart the app.

  • Run the packager with `--reset-cache` flag.

  • If you are using CocoaPods on iOS, run `pod install` in the `ios` directory and then rebuild and re-run the app.

  • If this happens while testing with Jest, check out docs how to integrate AsyncStorage with it: https://react-native-community.github.io/async-storage/docs/advanced/jest

If none of these fix the issue, please open an issue on the Github repository: https://github.com/react-native-community/react-native-async-storage/issues

Expected behavior

Repro steps

1. Created project using expo bare workflow

2. Web and Mobile project using yarn workspaces

3. When I use apk using scanning code from expo server then AsyncStorage work successfully (expo start cmd use for running APK)

4. If I use expo:build android -t apk then expo create apk on their platform

5. Download that APK from the expo server

6. If I install that downloaded APK, and start using it, on app lunch it crashed and give me the above error log

7. If I remove AsyncStorage lib, and follow the above steps then app works fine, but I need this lib in my app.

Environment

• Async Storage version:1.12.0
• React-Native version: 0.63.0
• Platform tested: Android
• Logs/Error that is relevant: If we scan the app from expo client then it works fine, but if I tried to create APK using expo:build android -t apk then it crashed on app launch. -**“expo”: “~38.0.9”,

when you run expo build:android -t apk you will see this:

╰─$ expo build:android -t apk
⚠️  expo build:android currently only supports managed workflow apps.
If you proceed with this command, we can run the build for you but it will not include any custom native modules or changes that you have made to your local native projects.
Unless you are sure that you know what you are doing, we recommend aborting the build and doing a native release build through Android Studio.
? Would you like to proceed? › (Y/n)

i guess you proceeded anyways. you shouldn’t 😛 the build service currently only supports managed apps. feel free to dm me on twitter @notbrent and i can help you try out a preview of our new build service that supports bare react-native apps too.

@Krizzu - feel free to close this issue

Hi @Krizzu @brentvatne , take a look into this
