Question:
I would like to update you that after a deep research I found that the problem is the rooted application.
I succeeded to solve it by copying the file libchilkatcrypt.so under /system/app/libchilkatcrypt.so (the root path) and by creating a direct link System.load("/system/app/libchilkatcrypt.so"); instead of using System.loadLibrary("chilkatcrypt");
Answer is above...
