然后就可以开始开发Qt应用程序，为了演示，我只是随便写了一点。然后直接点击运行（CTRL+R）。
倘若出现这个错误：
Starting remote process ...
Can't find eu.licentia.necessitas.industrius.example.Yiyaaixuexi process
解决方案是：
在run选项设置Android target SDK 为 android-8
倘若出现错误信息为：
Starting remote process ...

解决方案：
这种错误并不是环境配置的原因，而是Qt应用程序本身的设计不符合现有平台工具对android的支持。
比如：label上有中文字符等…… 改用英文字符就可以pass的。
如果你研究出了对中文字符支持的方案，欢迎交流下～～
顺利的话，编译通过后会自动弹出android模拟器，但是初次运行程序会遇到这个问题：
