Odd Files in an Android apk

[Dan Friedman]

Using LC version 9.6.1 (rc1), I built by Android app.   The app seemed a bit on the large side.  So, upon examining the files in the apk, I found this:

------------------------------------
Volume in drive D has no label.
 Volume Serial Number is 7C03-D597

Why would there be an iOS folder in the tsNet directory of an Android apk?

Also, I did not select the "Android x86" checkbox in the Application Setting, but the external for tsNet External-x86 was still included in the apk:

Perhaps this is a Bug or are all these files somehow required?   Any thoughts?
