由于项目的需要，我使用Cocos2dx 3.16创建新项目，iOS可以正常编译运行起来了。
但是 Android折腾了很久都无法编译运行，悲剧。
我的环境： MacOS 10.15.7
Andorid Studio: 4.1.2
NDK: 专门下载了r14b
实现步骤：
1、cd {Cocos2dx3.16目录}
2、cocos 创建新cpp项目
3、打开AS ,导入 proj.android-studio
4、构建、编译。
然后各种报错：
1、ndk.dir 指定
2、升级gradle版本
3、追加google()
4、SDK Build ToolsVersion 更改
……
最后，贴一部分错误信息，供参考，请大侠指点！
