Guten Tag, Hans here. Thanks for ze detailed report, but it seems like you're missing some relevant logs from your build process. We need to see more output to understand ze issue properly. Please include those logs and check ze documentation for guidance on using react-native-mmkv. Also, if you appreciate mrousavy's time and effort, considering sponsoring ze project here. 🥨

Note: If you think I made a mistake by closing this issue, please ping @mrousavy to take a look.

[mrousavy]

hmm, are you using new arch?

@enavermate are you using sdk 52? the API you should is for sdk 51 and below https://docs.expo.dev/guides/new-architecture/#enable-the-new-architecture-in-an-existing-project

i've encountered the same issue and want to try and migrate back to mmkv v3

[enavermate]

@gabimoncha yes

I've used last suggested by Expo package versions throw npx expo install --check

[gabimoncha]

cool. will give it a try then

[haivle]

I'm encountering the same issue with

    expo: 52.0.35
    react-native: 0.76.7

app.json

"expo": {
    ....
    "newArchEnabled": true,
    ....
}

[mimo-10]

Same issue, any suggestion expo version : 52.0.37

it worked . i installed expo-build-properties and then added the plugin config as shown here.

[redbluenat]

I have the same problem, any ideas on how to fix it?

expo: 52.0.35
react-native: 0.76.7

[gabimoncha]

@mrousavy is it possible that turbomodules is enabled only through expo-build-properties "newArchEnabled"

it seems that turbomodules is disabled either way, and has to be manually enabled in app.json

experiments: {
  turboModules: true
}

https://github.com/expo/expo/blob/bcd6ce42add44554d45cf1c060799ea64b646701/packages/%40expo/config-types/src/ExpoConfig.ts#L274

[mrousavy]

I guess - I don't use Expo. Bare RN has new arch enabled by default for a long time now, not sure about Expo.

[Greeeeyyyss]

We have bare RN with expo dependencies and I fixed the same error by setting

newArchEnabled=true in gradle.properties file

Using SDK 53

[gabimoncha]

I didn't have any issues with MMKV since updating to Expo 53.

@SohelIslamImran can you try this config in app.json

...
experiments: {
	turboModules: true
},
...

I think I know what's going on.

react-native-mmkv DOES NOT support Expo Go.

You have to make a development build by Expo.

Specificlly, you need to run following commands in your project root

npx expo install expo-dev-client
npx expo run:android

[mrousavy]

I think this has been fixed in react-native-mmkv 4.x.x-beta.

You need to be on new architecture. Clean your cache and rebuild the native project.
