How do I remove strings from / obfuscate a compiled binary? The goal is to avoid having people read the names of the functions/methods inside.

It is a dynamic library (.so) compiled from C++ code for Android with the NDK tools (includes GCC)

I compile with -O3 and already use arm-eabi-gcc -g mylib.so to remove debugging symbols, but when I do strings mylib.so all the names of the functions/methods are still readable.
