Hmm and also note that the file names are added using the value of getAbsolutePath(). If its absolute path were not-canonicalized it would not work.

Why not just have File objects in the set files? They implement the desired equals() semantics:

I have tried both of the following :

  1. deleteBroadcastFile(new File(file.toString).getCanonicalPath)
  2. deleteBroadcastFile(new File((file.toString).getCanonicalPath))
    In both the cases IDE complaints !
