做的东西需要增加java调用C++函数的功能，使用了jni，
c++ hpp中加入代码：
#include <jni.h>
#include “platform/android/jni/JniHelper.h”
/*java调用c++中的方法/
extern “C”
{
void Java_org_cocos2dx_javascript_AppActivity_sayHello()
{
…操作
}
}
java AppActivity中加入代码：
public static native void sayHello();
public static void openScan() {
AppActivity.sayHello();
}
请问是什么原因呢？
