Android Studio Run Debug configuration error Module not specified

Question

I am getting a  Module not specified  error in my run config  I have no module showing in the drop down yet I can see my module no probs  The issue came about when I refactored my module name  changed the settings gradle to new name   Now when I go to project structure and select my module nothing shows in the screen  not even an error   I m not 100  sure  but the icon beside my module looks like a folder with a cup and not a folder with a phone   My exact steps -   Open in Android view Refactor directory name refactor module name change settings gradle contents  name to new name

This issue also may happen when you just installed new Android studio and importing some project  in the new Android studio only the latest sdk is downloaded for example currently the latest is 30  and if your project target sdk is 29 you will not see your module in run configuring dialog  So download the sdk that your app is targeted  then run Sync project with gradle files
