I have tried this on multiple kitkat running devices: Z ultra, TF700t, but with no luck.
It just doesnt work.
With TF700, i can see the file open screen, but touches are greatly off the mark.never was able to select the correct folder.
With z ultra, it just hangs at the start.
(tried on multiple builds..6-Jun, 27-June etc.,)

Maybe kitkat is not supported??

Edit: I had an old kindle fire lying around; runs 2.3.4; Tried the Koreader on this and it works rather splendidly. So its probably the android version or device resolutions that cause it to hang.
