Are you sure you load correct libraries in other classes with System.loadlibrary?
您确定使用 System.loadlibrary 在其他类中加载正确的库吗？
If yes, I think quick solution can be putting all libraries in a folder that exists in os's PATH (for instance system32, windows) This has worked for me everytime if there is no any other issue
如果是，我认为快速解决方案可以将所有库放在 os 路径中存在的文件夹中（例如 system32、windows） 如果没有任何其他问题，这对我每次都有效
