我在 android cocos2d-x 项目中运行 build_native.sh 时遇到问题。原来是一些链接问题。我创建的 cpp 文件未编译，因此成为未定义的引用。
这是错误：

有人说我需要列出我在 Classes 文件夹中的 Android.mk 文件中创建的所有 cpp 文件。但是在我查看 Classes 文件夹后，那里没有 Android.mk。那么我现在应该如何列出 .cpp 文件呢？
更新 ：
我知道 jni 文件夹中有 android.mk 文件。但即使我在那里列出了我所有的游戏 cpp 文件，cpp 仍然没有在 build_native 过程中编译。所以我真的不知道如何列出我的 cpp 文件。
