🔧 undefined symbol: RNWorklet::JsiWorkletContext::getWorkletRuntime()

[Danushka96]

How were you trying to build the app?

I updated Vision Camera 3.4.0 due to the fps dropping issue in Android in the previous version. Previously it was built without issue. But after update I got this build issue

Works with VisionCamera_disableFrameProcessors = true in gradle-wrapper.properties

buildToolsVersion = "33.0.0"
kotlinVersion = "1.7.0"
kotlin_version = "1.7.0"
minSdkVersion = 26
compileSdkVersion = 33
targetSdkVersion = 33

Can I disable it if I need to use CodeScanner feature?

Can you build the VisionCamera Example app?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

check this: https://github.com/mrousavy/react-native-vision-camera/issues/1770#issuecomment-1707550362 maybe can help

[mrousavy]

Can I disable it if I need to use CodeScanner feature?

Yes, FPs can be disabled and the CodeScanner will still work.

If you dont install react-native-worklets-core, it should work right?

[Danushka96]

Yes, Working without issue when removing react-native-worklets-core from the project.

Hi, just updated to v3.6.6 and noticed in the changelog that this issue should be fixed by https://github.com/mrousavy/react-native-vision-camera/commit/75fd9248996caeccccec65da8f6c950c8d440e47

After a a clean install of my project, I get the undefined symbol: RNWorklet::JsiWorkletContext::getWorkletRuntime() error when building via npm run react-native run-android.

However, building via Android Studio (Giraffe | 2022.3.1 Patch 2) succeeds. Then subsequent builds via npm run react-native run-android will also succeed.

gradlew clean will make the build error return and another single build via Android Studio fixes it.

I went back through my project's history use of RNVC v3 and this issue has always been there. I never noticed it before as I typically kick off builds via Android Studio.

I have no idea why Android Studio builds would behave differently to npm run react-native run-android.

Build Error Log: rnvc-build-error.txt

Edit: Deleting the ./android/.gradle folder appears to have resolved my issue. Building fine now from commandline.

Anytime i change other expo libraries dependancies that require a new dev-client, the android compile fails for the above error (undefined symbol: RNWorklet::JsiWorkletContext::getWorkletRuntime() error when building via npm run react-native run-android) . I have to delete the /android/.gradle folder (as noted by @ldstein). I havent had to do this for any other library ive played with thus far.

Either im doing something wrong (only been playing with react-native for a few months so, very possible), or there still is something fishy going on.

[mrousavy]

Maybe some caching issue. I still don't know why this happens, I am focusing on higher priority issues at the moment. But if someone fixes this, I'll happily accept PRs here! ❤️

[mrousavy]

It builds fine for me, both in VisionCamera and in a new RN app.

[DevMinhThu]

Hello, I cleared the cache according to the instructions but the error still occurs, please help me. Thankyou very much.
