        // /vendor/lib, /odm/lib and /product/lib are added to the native lib search

        // paths of the classloader. Note that this is done AFTER the classloader is

        // created by ApplicationLoaders.getDefault().getClassLoader(...). The

        // reason is because if we have added the paths when creating the classloader

        // above, the paths are also added to the search path of the linker namespace

        // 'classloader-namespace', which will allow ALL libs in the paths to apps.

        // Since only the libs listed in <partition>/etc/public.libraries.txt can be

        // available to apps, we shouldn't add the paths then.

        //

        // However, we need to add the paths to the classloader (Java) though. This

        // is because when a native lib is requested via System.loadLibrary(), the

        // classloader first tries to find the requested lib in its own native libs

        // search paths. If a lib is not found in one of the paths, dlopen() is not

        // called at all. This can cause a problem that a vendor public native lib

        // is accessible when directly opened via dlopen(), but inaccesible via

        // System.loadLibrary(). In order to prevent the problem, we explicitly

        // add the paths only to the classloader, and not to the native loader

        // (linker namespace).
