Unfortunately you cut off your log just before it got interesting, when it would have shown the version of JSON API installed in your Android Kodi client - presumably it's not recent as it doesn't support the JSON TexturesDB API introduced with JSON 6.9.0 (added in Kodi 13 on 26 Oct 2013).
Without TexturesDB API support the script has to access your SQLite database directly, and in order to do that it needs access to the filesystem ether via a mount point, or running the script locally on the client (both of which will likely be problematic for Android, in which case upgrading the version of Kodi would be best).
