On a Samsung Galaxy S4 Google Play Edition running 4.4 and non-rooted (I'd prefer not to root a device used for professional development purposes)
Having stored some ebooks on my external SDcard, I decided that I wanted to add some audio as well (as my internal device storage is quite full.)
As far as I can tell not one app (nor adb) can perform any write operations to the external SDcard's root directory.
The one exception that I've found is that my ubuntu computer, can create and rename directories inside /storage/extSdCard/Android/data/ even though none of my apps can.
Is there a workaround for this that doesn't involve rooting the device?
