this is what i did might helps
uninstalled kodi 15.2 then install again then run it and let it update (waited 3 mins)dont close kodi
go to browser and search kodi download
click jarvis 16 android arm (start downloading)waited 10 mins by that time downloading is done
waited 10 mins cause my first 4 tried i went back to kodi early and i think thats when i have problem because the download is not done yet and waited for download to be done...
ok after 10 mins go back to kodi,go to program,click android apps,click download then click on jarvis 16,it will install and close
launch kodi and boom jarvis is there.....hope it helps, good luck everyone
