Android Build Fails with React Native Reanimated Codegen Error

[guillem-aistech]

Current Behavior

When running one run:android, the build fails with a CMake error related to react-native-reanimated. The error indicates that the codegen directory /node_modules/react-native-reanimated/android/build/generated/source/codegen/jni/ doesn't exist, causing the CMake configuration to fail.

Expected Behavior

The Android build should complete successfully and launch the app on the emulator without CMake errors related to react-native-reanimated codegen files.

One Version

1.1.486

Platform (Web, iOS, Android)

Android (tested on emulator Medium_Phone_API_36.0)

Reproduction

1. Set up a new OneJS project with react-native-reanimated dependency
2. Run pnpm --filter @atds/apps-atds android (or one run:android)
3. Build fails with CMake error during :app:configureCMakeDebug[arm64-v8a] task

Full error output:

Attempted fixes that didn't work:

• Clean build (rm -rf android/app/build android/.gradle android/app/.cxx)
• Reinstall dependencies (rm -rf node_modules && pnpm install)
• Running react-native codegen manually
• Running npx expo prebuild --platform android --clean
• Running ./gradlew clean in android directory

Environment details:

• Using pnpm workspace (monorepo setup)
• Kubuntu 22.04
• Java 21.0.7 (Temurin via SDKMan)
• Android SDK with NDK 27.1.12297006
• CMake 3.22.1 (auto-installed by build process)
• The missing directory: /node_modules/react-native-reanimated/android/build/generated/source/codegen/jni/

It looks like the CMake error is caused by missing codegen output for react-native-reanimated. Try running the following from the android dir:

./gradlew generateCodegenArtifactsFromSchema

This should generate the required jni/ directory and resolve the CMake configuration error.
