All things happen for a reason. :)
My rationale, is that I have a feature which is location based. I want to
be able to let the user toggle the feature on/off via a switch on a
settings page. In the case where a user has permanently deactivated
location permissions for the app, I want this switch to equally be
disabled, with a message instructing the user to edit global permissions,
if they wish to use the feature.
I haven't tried out *shouldShowRequestPermissionRationale*, since I don't
really understand what it does from the docs.
"Returns true if you should show UI with a rationale for requesting a
permission."
I mean... What rationale? What UI?
