C/C++ BUILD->Builder Settings:  ${NDKROOT}/ndk-build.cmd

C/C++ General->Path and Symbols->Includes:

előtte persze Windowsban beállítottuk környezeti változónak az NDKROOT-ot (NDK r8 path)

vagy:

cmd.exe (nem cygwin)->cd PROJECT->  NDK_PATH/ndk-build  -> .so file-ok megjelennek

ezután CRTL+F11

c++ android log:

#define LOGE(...) ((void)__android_log_print(ANDROID_LOG_ERROR, LOG_TAG, __VA_ARGS__))
