本例子中使用的是ndk中的hello-jni工程

$ vim ../android/jni/Android.mk
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := hello-jni
LOCAL_SRC_FILES := hello-jni.c
LOCAL_LDLIBS := $(LOCAL_PATH)/libluajit.a   #加上这句

include $(BUILD_SHARED_LIBRARY)
#include "lua.h"
#include "lualib.h"
#include "lauxlib.h"  // 引入头文件

lua_State* L;         // Lua指针

    L = lua_open();   // 打开Lua指针
    luaL_openlibs(L);
    luaL_dostring(L, "return 'Hello from Lua !'");  // 执行Lua语句

    lua_close(L);

    return (*env)->NewStringUTF(env, str);
