Android: Screen transitions broken in Example App🐛

[ldstein]

What were you trying to do?

On Android, if the Permissions Screen is displayed and permission is granted to Camera and Microphone, the view will fail to transition to the Camera Screen.

Current workaround is after granting permission, terminate the app and reload - it will then directly load the Camera screen.

I believe it is caused by an incompatibility between @react-navigation/native and react-native-reanimated@2.3.0-beta.2 and is not unique to the Example App (navigation is broken in other projects where I've introduced the alpha or beta versions of RNR).

The example App screen transitions haven't worked on Android since ~2.7.0 after the move away from wix/react-native-navigation.

Maybe worth watching software-mansion/react-native-reanimated#2460 as it looks related.

Thanks for the bug report!

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!
