Compilation Error with React Native MMKV: NativeMmkvPlatformContextSpec Not Found

[waqarkhan09099]

I encountered an error while trying to build the project with react-native-mmkv. The build fails with compilation errors indicating that the NativeMmkvPlatformContextSpec class and other symbols cannot be found.

React Native Version 0.74

Execution failed for task ':react-native-mmkv:compileDebugJavaWithJavac'.

Compilation failed; see the compiler error output for details.

Please advise on any known issues or potential fixes. If this is a bug, I would appreciate guidance on how to resolve it or a potential timeline for a fix.

Guten Tag, Hans here! 🍻

It looks like you are encountering a build issue with react-native-mmkv, but I am missing some important details. Could you please provide ze build logs from your Android Studio or run adb logcat to capture any relevant output? This will help mrousavy understand ze problem better and assist you.

Additionally, please make sure you followed ze installation instructions carefully from ze documentation. If ze problem persists, we can then dive deeper into it.

If you would like ze repository owners to prioritize your issue, consider sponsoring mrousavy here.

Let’s get this sorted out!

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

Looks like you are using a 3.x version of this library. What version exactly are you using. Do you have new architecture enabled for react-native?

[waqarkhan09099]

Can I replace it with a version lower than 3.x?

@waqarkhan09099 If you do not have new architecture enabled you should be using 2.x latest, if using new architecture I know for a fact the last 3.x beta was working good with RN 74 as I was using that personally.

I was working on my local upgrade today, I did find 3.0.2 did not work with RN 74.x I stuck to the beta for that and then went to 3.0.2 with my upgrade to RN 75. I have validated building on Windows for android, I will validate my Mac builds and Ios builds when I get back on Sunday

@waqarkhan09099 You can use "react-native-mmkv": "^2.12.2" this version of library in current "react-native": "0.75.2" version project. Its working fine for me. Date:- 09/06/2024

Thanks for your assistance. That version works for me. However, I suggest that the react-native-mmkv latest version be compatible with the react native version 0.70.x till lastest

Warning Description After Run Android :

While building the react-native-mmkv library, the following warning is displayed in the logs: node_modules/react-native-mmkv/MMKV/Core/MMKV_IO.cpp:1625:29: warning: 'const' qualifier on reference type 'MMKVKey_t' (aka 'const basic_string &') has no effect [-Wignored-reference-qualifiers] auto packKeyValue = [&](const MMKVKey_t &key, const MMBuffer &value) {

Proposed Fix: Removing the const qualifier from the reference type MMKVKey_t &key will resolve the warning.

@waqarkhan09099 In this case v2 is old architecture, v3 is new architecture, complete re-write for the most part for @mrousavy
