title: One click destroyed my Android Studio Project... How can I put it back together?
body: <p>What I wanted to do was simply this:
  Generate a Debug APK without having it launch emulators and perform downloads.
  (No, the "compile" and/or "build" is not creating a new debug APK... but that's for another post). 
  After searching, I came across this:
  <a href="https://stackoverflow.com/questions/16709848/build-unsigned-apk-file-with-android-studio">Build unsigned APK file with Android Studio</a></p>
  
  <p>So I followed the steps.  Initially my "Gradle Projects" pane was completely empty... but it was building the project just fine.  So logically, I have to assume that having an empty "Gradle Projects" pane is the norm.</p>
  
  <p>After performing those steps in the above link, I was now getting 48 (!!) different APK files, where I used to get 6, with such names as "X86-arm-armabi-7a"...  (Really?  these apks were mixing X86 with arm code??  (my project does have a few native libs in it))</p>
  
  <p>So, to revert back, I simply go in opposite direction. I went back to the gradle pane, and pressed (-) to remove what I added.  Yup... one click.</p>
  
  <p>Opps.</p>
  
  <p>Now, it's gone.  All the files are still there.  But there is no "project" anymore.  I open Android Studio, and the project pane is empty.  The "Reopen" menu doesn't list it anymore...</p>
  
  <p>In any other environment, simple undoing what you did would take you back to the state you were in before.  But not with Android Studio...</p>
  
  <p>All the tutorials I can find are about writing Android apps... nothing about how the underlying architecture of Android Studio actually functions.  Other IDEs use make files or solution/ project files like SLN, DSW, QPF, MCP... I can find nothing like that in Android Studio (which would at least give me a restore point from the source repository)</p>
  
  <p>How can I "reconnect" the files back into a "project"?  Any trail of clues would be appreciated.</p>
  
  <p>These kinds of fragile things make Android Studio very difficult (and scary) to use...</p>
