Draco plugin won't work from non main thread?

I tried to integrate the Draco mesh loader library into my Unity app.
https://github.com/google/draco

The plugin works on both the main thread and the non main thread on the desktop.
On Android it works on the main thread, but not on the non main thread.
This is also after I removed any initialization of Unity Classes such as Mesh so it won't fail on that on the non main thread.

Is there a limitation in Unity to use binary Android plugins outside the main thread?
There doesn't seem to be any error on LogCat, the failure is also once I call the external plugin function. If I remove that function form the code, it continues, otherwise the script crash there.
No error for the crash as well.

 

I'm trying to use your Draco fork for Unity and can't even get the sample project running.
You have one benchmark obj which then tries to decode a draco mesh which is already included and set up. However, even that fails with the error Failed: Decoding error. On line 109 DracoMeshLoader.cs. Any tips on how this can be fixed/used? How about using Draco to actually Encode a mesh, could you give us more details about that?
