Unable to select module app

Hi,

I tried to follow the steps before starting to run. I am new to AndroidStudio. I think I've already imported the testing samples project successfully. I want to try to run for Basic Sample Expresso. However, I'm stuck to create and run the Instrumented test configuration steps. There's no module that I can select. Kindly assist. Thank you.

**So this is the steps:**

**This is my screenshot from Edit Configuration settings in AndroidStudio:**

从链接的 ui/espresso/BasicSample 项目以及 issue 中描述的 Instrumented 测试配置步骤开始。重现屏幕截图中显示的 Android Studio 设置，然后确定为什么没有可用的模块；当原因和可行的配置步骤都已记录时，即表示完成。
