react-native-mmkv-storage: Android build fails

I am also getting same problem ,I tried all solution above but not work for me ,any ldea for help me?

Execution failed for task ':app:configureCMakeDebug[arm64-v8a]'.
> [CXX1405] error when building with cmake using C:\project\flutter_ffi_example\android\CMakeLists.txt: Build command failed.

Okay,

I found it. It simply does not work with lower and higher than 3.10.2.4988404 CMake version.

Also, in the local.properties file, I had to define cmake path:

cmake.dir=/Users/username/Library/Android/sdk/cmake/3.10.2.4988404

Thank you so much for the live help and the support for the library @ammarahm-ed 😃

I’m getting a similar error.

Using react-native-mmkv-storage@0.6.4, react-native@0.63.4, CMake 3.10.2.4988404, NDK 21.4.7075529, and the build.gradle change described here. No other JSI packages. I’ve tried deleting node_modules and running ./gradlew.bat clean, didn’t change anything. However, downgrading to react-native-mmkv-storage@0.6.0 works.

It should work. Maybe something greater than 3.18 would work fine.

@ammarahm-ed Can you tell me where to upgrade it?

Uncheck cmake 3.6.x. Apply changes.
