I am trying to use the .so external library in my Android project. It's not clear to me how can I access the classes in the library once it's loaded via System.load("path to lib")?

The library is already there, and it's already compiled for use on mobile devices.
The loading process does not cause errors.
Due to the specifics of the project, I cannot use .so files from the unpacked apk along the standard path - I need to connect it in the code via System.load("path to lib").

Please, tell me, what is the syntax for referring to classes in a loaded library?
