Difference Between uses-permission-sdk-23 and uses-permission?

Question

I just come to know newer tag in android manifest file called \"uses-permission-sdk-23\"

Answer 1

user-permission-sdk-23 specifies that the app that wants a particular permission is running on SDK version 23 or higher. It is used when you update your app to run SDK 23 elements and the users running a lower API which does not support the new elements.

Android manifest - user permissions
