  <p>I tried to add an .mp3 file to android studio for use in an app</p>
  
  <p>a menu popped up as in the link's question, which wasn't clearly answered, however, unlike them, I clicked java, and that was completely the wrong thing to do. </p>
  
  <p>NOW my .mp3 file is no longer in the raw directory where I put it, and I can't add it again either. It says Error: cannot create class file when I do.</p>
  
  <p>No idea how to fix, please help </p>
  
  <p>//Edit: here is more information to help clarify a few things</p>
  
  <p>The raw directory is empty</p>
  
  <p>adding .mp3 files to ANY directory is impossible because the file type .mp3 is registered as a java class but cannot resolve, thus creating an error.</p>
  
  <p>I need to know how to un-register .mp3 files in android studio</p>
  
  <p>//Edit: Update as I work on it and discover things:
  The .mp3 file IS in the raw directory and can even be used in applications that correctly call it, HOWEVER android studio doesn't display it and won't allow me to add more .mp3 files via drag-and-drop. I can add files by going through my computer </p>
