expo: [SDK-46] expo-modules-core CMake errors

Had a similar issue relating to the CMake file within expo-modules-core recently after upgrading the gradle version.

To fix it I:

Went to SDK Manager within Android Studio, then in SDK tools, check CMake then Apply (if it isn’t already), otherwise uncheck then apply and finally check and apply again (This should ensure you’re on the latest version).

Then within the expo-modules-core build.gradle file, remove this block of code:

 externalNativeBuild {
    cmake {
      if (REACT_NATIVE_TARGET_VERSION >= 71) {
        path "CMakeLists.txt"
      } else {
        path "legacy/CMakeLists.txt"
      }
    }
}

I believe issues with CMake may be occuring because it’s defaulting to an older version of CMake due to the block of code above.

I had this same issue in my own project and when I opened Android Studio, it recommended upgrading Gradle Plugin from 7.1.1 to 7.2.2. After doing that, Make Project and Run 'app' worked fine.

I tried doing the same with the minimal reproducible example above, first getting the CMake errors, then upgrading Gradle Plugin to 7.2.2, and I was able to Make Project without an issue.

So I guess the question is … how do we upgrade Gradle Plugin to 7.2.2 in a config plugin or some sticky way so that EAS builds don’t fail?

Edit: interestingly enough, the eas build went through without an issue 🤷‍♂️

I’m also seeing this:

React Native 0.69.5 React 18 Expo 46.0.13

I’m experiencing the same issue with a bare RN app with expo-modules-core and expo-av throwing this error when syncing gradle

works with: “expo”: “46.0.10”, “react-native”: “0.70.3”

Did you add some specific code here for running expo 0.46.10 + react-native 0.70.3? For me it doesn’t work for android

That’s all. I got this error and solved it by clearing the Android Studio cache, also additionally android: ./gradlew clean and rm -r $HOME/.gradle/caches/

The workaround that works for me:

1. Run npx expo prebuild
2. Open Android Studio and the Android project
3. Wait for the build to fail with the CMake error
4. Ignore the suggestion to upgrade Gradle
5. Close Android Studio
6. Open Android Studio and the project
7. Click Build } Make Project

Strangely, trying Build } Make Project without first closing Android Studio doesn’t work. I also tried upgrading the Gradle plugin, and deleting ~/.gradle/caches/, but nothing worked until closing and re-opening Android Studio.

@evgenyshenets91 this worked for me, thanks

works with: "

Tried this today. Same issue. I see only one solution create a new project with react native CLI and copy-paste js files from the expo project.

Bare project I started experiencing this same issue when upgrading expo-av from 11.2.3 to the current latest: 12.0.4.
