我遇到同样的问题。虽然有你的项目选择，去顶运行菜单。打开运行配置，然后选择您的目标虚拟设备。点击应用，然后运行该项目。

I encountered the same problem. While having your project selected, go to the Top "Run" Menu. Open "Run Configurations" and select your target virtual device. Click apply, and then run the project.

这对我来说工作得很好。

It worked fine for me.

祝您好运！
