I'm trying to implement google map in a fragment, I have succeeded adding the map and markers on it, but now I need to show current users location and when it updates. I've tried following answers on this, but all answers were not giving any results only closing application instantly or giving error without even starting application. I've followed many guides on setting users location in activity, but failed to transfer that knowledge to fragment. Please keep in mind I've just started coding with android studio and I might not understand all the information.
