What is this android.permission.STATUS_BAR_SERVICE used for? And what is the difference between uses-permission and permission?

Question

I want to know more about this permission and its signature level?

<permission
        android:name="android.permission.STATUS_BAR_SERVICE"
        android:protectionLevel="signature" />

Like why and what is it used for ? Is this permission used for allowing some special feature?

Also i want to know the difference between <permission> and <uses-permission>

I am using a foreground service and NotificationManager and i am making an app that has skype like behaviour so i want to know whether this permission has any use for me or not.

Thanks in Advance

The STATUS_BAR_SERVICE permission is used for apps that what to be the actual status bar. This is a protected permission so unless you're building your own ROM that includes replacing the status bar then I don't think this is the permission you want.

By the sound of it all you want to do is put notifications in the notification bar. So just using the functionality here should be all your interested in. You shouldn't need to mess with any special status bar related permissions.
