Build Failure on Android After Updating `react-native-mmkv` with React Native 0.75.2

Hello, I've encountered a build issue after updating the react-native-mmkv library. My project, which uses React Native version 0.75.2, fails to build on Android, throwing the following errors:

Faced the same problem, configuring newArchEnabled=true in android/gradle.properties also seems to fail to compile

[RohovDmytro]

Confirm to have no issues with new arch on RC, but 3.0.1 fails to build on Android.

[coder-xiaomo]

Thank you! Version 3.0.2 solves this problem perfectly.

[gituser8796]

@mrousavy it stopped working on web

[mrousavy]

@gituser8796 PRs appreciated

[nitinpatelm]

Still am able to see the same error even with version 3.0.2

"react-native-mmkv": "^3.0.2",
"react-native": "^0.75.2",

[namhac-pionero]

me either

[kbqdev]

same error with @nitinpatelm

[kbqdev]

Thank you! Version 3.0.2 solves this problem perfectly.

What version react-native you use ?

[phvasconcellos84]

Any solution?

[Yahya10Shoaib]

Same error on latest React native better to move on Asyncstorage

[hasbimsdd27]

I just downgraded the version to 2.12.2 and it's working fine

"react-native-mmkv": "2.12.2",
"react-native": "0.75.3",

[bobanminic96]

Facing same issue.

"react-native-mmkv": "^3.0.2", "react-native": "0.75.3",

[amutsch]

@bobanminic96 make sure you are using new architecture, mmkv 3.x only works with new architecture, if you are still on the old architecture you need to use 2.12.2

[aleksandarber]

Had the same issue the problem was i was using react-native version 0.74.2 and my mmkv version was 3.0.2, fixed it by changing the mmkv version to 2.12.2
