Comment (by sisbell):

 This problem occurs around the environmental variable ${user.home}. When
 this is set, we use it to tell tor where to place the DataDirectory. This
 is intended to be used for the desktop, as its an unsupported property on
 Android. If it is not set, then we pick a default location on the device
 that the user has access to. This is expected on an Android device.

 On KitKat devices the system property ${user.home} is set to system root
 "/". Since the user doesn't have permission to access the root directory,
 startup fails. On other Android platforms the ${user.home} property value
 is null and tor starts up correctly.

 I'll get in a fix for testing.
