JavaVTK Example Android Crash(vtk8.2)

I have successfully compiled the static library for arm64 version of vtk8.2 using ndk r21e, and when I integrated it into the JavaVTK Android Example, I was able to successfully build the APK. However, during runtime, it crashed directly, and after printing, it was found that all members in vtk were null. What should I do to run the JavaVTK Android Example smoothly
