🐛 App crashes on Android: UnsatisfiedLinkError (vision-camera-face-detector)

[fleuverouge]

What were you trying to do?

I wanted to detect faces with vision-camera-face-detector.

I tried cd android/ && ./gradlew clean && cd .. && watchman watch-del-all && rm -rf $TMPDIR/metro-cache && yarn cache clean && yarn start --reset-cache

Reproduceable Code

const faceFrameProcessor = useFrameProcessor(
        frame => {
            'worklet';
            const scannedFaces = scanFaces(frame);
            runOnJS(setFaces)(scannedFaces);
        },
        [],
    );

What happened instead?

The app crashes when the screen which contains the Camera view is reached.

Huh that's weird, are you sure you rebuilt the native code correctly?

Hi @mrousavy I've tried to rebuild the code many times (cleaned cache, removed build folders, deleted node_modules...), also copied build.gradle from the sample project... Without frameProcessor, the camera works normally. The frame processors also run on iOS. The build log stated that frame processor is enabled.

I just got the same error.
I solved it by installing react-native-reanimated and applying the patch-package steps from this comment (for react-native 0.69)

Hey! I've rewritten the entire Android codebase of VisionCamera from CameraX to Camera2 in the efforts of ✨ VisionCamera V3.

I just now completed the Camera2 rewrite and I believe the core structure is running, but there might be some edge cases to iron out. Can you try and test the PR #1674 for me to see if you can still reproduce this issue here?

Here's an instruction on how you can test that: #1674 (comment)

If the issue cannot be reproduced with that version/PR anymore, then hoorayy, I fixed it! 🎉
Otherwise please let me know and I'll keep this issue open to keep track of it.

Thank you!
