app crashes on startup

[ronelgazar]

Hi I have cloned your repository, and tried to run the example but the app crashed in the emulator with no errors

I'm new to flutter so i hope you can help me
Thanks in advance.

[ronelgazar]

by the way great documentation

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

[ronelgazar]

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

Please confirm whether the size of the .aar file(flutter_hand_tracking_plugin/android/libs/hand_tracking_aar.aar) in your project exceeds 100MB, if only a few kb indicates that the .aar file you downloaded is incomplete

[ronelgazar]

The size of the hand_tracking_aar.aar file is 103.21600 MB

[zhouzaihang]

Please provide the log of the program running.

I think the problem may be in flutter sdk:

flutter/flutter#35989

@ronelgazar How did you fix this problem?

[ronelgazar]

@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.
