title: App module disappeared in android studio
body: <p>I had app module running on my android studio project until I pressed delete by mistake. I am now unable to run my project as it doesn't detect app module.</p>
  
  <p>I can see app folder in project view (containing build, libs, src folders) but I don't see it in android view or configuration setting where it says </p>
  
  <p>I have an old apk file of the project.</p>
  
  <p>I shared my project on github.
  Please help me get my module back so that I can run my project.</p>
