Currently I just started to using NDK and now I have some question in my mind.

Is there anyway to modify previously created .so file using NDK? can we modify that .so file?I just want to change some specification and want to rebuild.

Any help and suggestion will be appreciated.
Thanks in advance

    You cannot change the .so file directly. You can, however, change the source code (in C or C++) and recompile it using the NDK. If you do not have access to the source, however, your chances are rather slim.

    You may be able to de-compile/disassemble the .so, but it will prove extremely difficult if not impossible to recompile it back into .so
