as seen on android docs : https://developers.google.com/android/reference/com/google/android/gms/maps/googlemap.onmylocationchangelistener

googlemap.onmylocationchangelistener deprecated. tutorial using old.

from link above, able redirected newer tutorials , how-to guides (which solve setmylocationenabled error).

edit : recommended deprecated, such life in software development. if you're looking newest way of doing it, check out android documentations.
