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

if the app is running on a device with SDK version 23 or higher. If the device is running SDK version 22 or lower

when you update an app to include a new feature that requires an additional permission. If a user updates an app on a device that is running SDK version 22 or lower, the system prompts the user at install time to grant all new permissions that are declared in that update. If a new feature is minor enough, you may prefer to disable the feature altogether on those devices, so the user does not have to grant additional permissions to update the app. By using the uses-permission-sdk-23 element instead of uses-permission

you can request the permission only if the app is running on platforms that support the runtime permissions model, in which the user grants permissions to the app while it is running.
