Description

According to our docs, and our iOS behavior - if Ti.FIlesystem.File#getDirectoryListing() is called on a file or a directory that does not exist, it should return null. On Android it returns an empty array.

*Closing ticket.* Verified fix in SDK version: 7.4.0.v20180810061237. getDirectoryListing no longer returns an empty array and now returns null. *FR Passed (Test Steps):*

Created a new application using Titanium

Added the following code in to the application

   var nonExistentDir = Ti.Filesystem.getFile('madeup');
   Ti.API.info(nonExistentDir.getDirectoryListing()); // Should print 'null'
   var file = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'app.js');
   Ti.API.info(file.getDirectoryListing());  // Should print 'null'

Ran the application

Able to see `null` printed in the console unlike previously where an empty array was printed.

   [INFO] :   null
   [INFO] :   null

*Test Environment*

   Operating System Name: Mac OS High Sierra
