I Work as cybersecurity consultant and now i'am in mission to reverse engineering of mobile app. I always reverse it using Jadx and dex2jar ... the problem that after reverse them i found some native methodes with like (system.libraryload("share_c++") system.libraryload("android-network") and they have system.securityloadlibrarry("mainJni")) but i can't found the .so or library files anyone can help me please
One approach would be to monitor all file-system activities e.g. using inotify-tools.
Run it with root permissions, checking recursively for all read/write operations in the app directory. This should allow you to identify which file is created (in case the native library is decoded/decrypted or loaded from an online source) and what files are loaded.
