Thanks for your answer, but i dont understand whats the logic, why PERMISSION_GRANTED is linked up with PackageManager as PERMISSION_GRANTED is not a package. – N.JB Sep 19 '17 at 17:37

It's a constant defined in `PackageManager` class. As `PackageManager` is a *Class for retrieving **various kinds of information** related to the application packages*, it also allows querying for permissions granted to a certain package. If you open the source code to `ContextCompat.chekSelfPermission` you'll see that it's just a shortcut to `PackageManager.checkPermission`. So the real question is "why ContextCompat.checkSelfPermission"? And the answer is: the keyword is "self". – Eugen Pechanec Sep 19 '17 at 17:41
