试图上课.尝试在下载的源代码中启动另一个项目.下次请使用文章本身中的消息论坛，您将在此处得到更好的响应.

That means you''re trying to run a class. Try starting the other project in the source you downloaded. And next time please use the message forum in the article itself, you''ll get better response there.

我认为您可以记录用户安装软件的日期或用户注册软件的日期.服务.
从那时起，每次用户打开软件或服务都将与注册日期进行比较.
希望这会给您一些额外的选择

I think you can record the date user install the software or the date user register the service.
From then, every time user open software or service will compare with the register date.
Hope this give you some addition option
