Android setup samsung galaxy sj7 not connecting

so ive followed the guide to setup my samsung galaxy crown and when i go to prompt commands to see if its connected it wont show up as a device. when i go to launch the game to the fphone it says no android phone detected. Codeworks is iru7. the guides say to use 6 but i dont know how to get the older version doesnt seem to be an option. any ideas?
