    I use C++ library to calculate some heavy task instead of using C#. It runs well on Editor but when I build to Android device, the build can not find the library. I tried my library on a new Android project from Android studio and I can run normally.
    Hope someone could help! Thanks in advance!

    How did you put your library into Unity project? Could you show layout and plugin settings?

    I built a library .aar in Android Studio and placed it in the "Plugins/Android" folder in Unity.

    Check if built apk file has your library in it.
    If it's only an .so file, you can put that file into Unity rather than .aar, that should work fine.
