Added in source. Xml file and same issue

If you do mysql -u kodi -p and then enter the password from your advancedsettings,xml file then that should log you into mariadb as the kodi user.  Then do show databases; to check that the db's exist.

Then you could try use MyVideos116; followed by select * from movie where idMovie = 1; and ensure it returns some data.

It says
Empty set (0.001 sec)

Add source
Directory contains movie

Movies scan and show up on computer
Nothing on android phone
