The official document also has a detailed introduction:

In short, system. Load should take the absolute path of so; The system. Loadlibrary should not have a path, and it should not have a lib prefix and a. So suffix. For example, you have an app with a package of com. Test. Demo and a libtest. So

Then, you can load it like this:
1. System. Load (getapplicationinfo(). Nativelibrarydir + “/ libtest. So”)

2. System.LoadLibrary(“test”);
