Requesting Location Permission At Runtime

I have a query implementing RuntimePermission for Location. When I tried to requestLocationUpdates, I got LintError suggesting me to add PermissionCheck for that line. Considering

Solution 1:

You do need to check for checkSelfPermission because with latest OS 6 (Marshmallow) you can revoke the permissions granted for an app by going into settings.
So even if user has granted the permissions to app during installation time, at runtime you need to doublecheck whether your app still has the permissions or user has revoked those permissions.
