app crashes on startup about flutter_hand_tracking_plugin HOT 12 CLOSED

by the way great documentation

from flutter_hand_tracking_plugin.

I suggest you use a real device for debugging. The simulator will always have some problems, even if no errors are reported

from flutter_hand_tracking_plugin.

I just tried it on my real device it's the same result the app crashes.

@ronelgazar How did you fix this problem?

@sonsosad
A bit late 😅, I don't remember how I did it but it something along these lines

1. reinstalled the hand_tracking.aar file properly using android studio
2. Installed mediapipe on my pc in order find the libmediapipe_jeni.so and replaced the original one
3. updated my flutter sdk (It was before null safety was introduced so I am not sure if it is relevant anymore)
4. built a debug apk
5. installed it on a physical device
6. Done

Have a nice day and
I hope it is still relevant.
