Specifies that an app wants a particular permission, but only if the app is running on a device with API level 23 or higher. If the device is running API level 22 or lower, the app does not have the specified permission.
This element is useful 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 API level 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 element instead of , 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.
For more information on permissions, see the Permissions section in the introduction and the separate System Permissions API guide. A list of permissions defined by the base platform is available at android.Manifest.permission.
