Not hand tracking about tflite4unity HOT 11 CLOSED

Hi, thanks for the notification.

On which branch are you working actually ? I could help further then.

from tflite4unity.

Thank you very much for answering. I am using master branch

from tflite4unity.

Ah ok I forgot to merge with the develop branch. Can you try out with the develop branch ?

from tflite4unity.

OK, I have switched to the develop branch. The same result.
I don't know if this can help, it appears when the build begins;

from tflite4unity.

Ok I tried with my own setup. I am working with Unity 2019.2.The rest is the same as yours. I am somehow not getting the same error with my version of the engine. A friend of mine also built with the Unity 2019.2 and there were no problems yet.

The gradle file format might be also changed for your Unity version.

I will try with the 2019.3 and report the results here.

Thanks again for the report !

@SevenAntares allright, I have just tried it out with 2019.3 and got the same problem. There are probably some changes which cause this problem during the communication between the Unity Runtime & JNI. I would encourage you to test again with 2019.2 to ensure that this problem happens because of the Unity version. I can note this as a known issue then.

In case the same problem occurs again, could you check the followings:

1. AR Foundations version must be 2.1
2. Check if any game object references are missing in the scene.

I have tried Unity 2019.2 with ARFoundation 2.1 and I have the same result. So I think I'm doing something wrong.
I open the "TFARInterface" project in Unity
Should I do something with the "TFLitePlugin" folder?
Forgive me for my innocence

Hi @SevenAntares
We checked out everything and built it multiple times with the current configurations but everything worked fine. You don't have to do anything with the TFLitePlugin. It is rather the android side and thought for the custom model inference implementations. The Android plugin is always built as a .aar library and put into the Plugin folder on the Unity side.

Is your device running the AndroidX ? Maybe it causes a problem currently...
Our setup consists of devices with Android 8.1 & 9 and so far they did not cause any problems.

If you have any older device I would also try with it cause I do not personally have any Android X devices right now. If you would ever try, could you report the results here ?

from tflite4unity.

@SevenAntares Could you also check your NDK version please ?

Ok, sorry I only have this Android device. Here I leave the concrete versions.
