ARCore: Create Image Database at runtime build

I can create an image database at runtime in the editor, but when building out to Android, I get an error stating that the functions I used no longer exist. The functions belong to ARCore. Is there a reason why the functions and members are erased on build? Is there a way around this?

hello there :)
check those scripts is there is something like :

#if (UNITY_EDITOR)
... your class/code ...
#endif

then remove those tags because that compiler flag erase them from built
