for Android, use the Android NDK and familiarize yourself with the steps required to build a shared library or a static library.

If you use C++ to implement the plug-in, you must declare with C linkage to avoid name mangling issues. By default, only C source files that have a .c file extension in the plug-ins have C linkage (not C++).

extern "C" {
  float Foopluginmethod ();
}

Note: If your static library isn’t compiled with -fno-exceptions and -fno-rtti flags, compatibility issues might cause application build failure.
