Comment (by sisbell):

 Tor bootstrap won't use the files/Download directory. This is something
 related to the firefox code. Of all the Android versions, !KitKat has the
 most problematic network stack when trying to create internal ports and
 use proxies and VPN. In some cases, its completely broken.

 On startup, the app prints out the error stream of the Tor process. If you
 aren't seeing that then it may be something to do with being unable to
 read or process the torrc file. I'll add this configuration check in the
 next version (I'll get an earlier version for you to test so we can see if
 that is the problem).

 Can you try and see if Orbot works on your version of KitKat? That would
 help narrow down what the problem is. If startup works with Orbot, then
 our issue is unlikely a network issue and would likely be an issue with
 installation and configuration.
