Requesting android.permission.READ_NETWORK_USAGE_HISTORY permission

I would like to see if I can read the network usage of my application, after some searching it seems that I could use the NetworkStatsService to achieve this, however when I call the Query methods against the NetworkStatsManager instance an exception is raised with the following details :-

Java.Lang.SecurityException: NetworkStats: Neither user 10578 nor current process has android.permission.READ_NETWORK_USAGE_HISTORY.

So I add the android.permission.READ_NETWORK_USAGE_HISTORY permission to the AndroidManifest.xml and also request the permission using Activity.RequestPermissions however I am still presented with the exception.

A couple of questions, from my search I found that the READ_NETWORK_USAGE_HISTORY permission might be protected so I added a protectedLevel attribute, as follows :-

<uses-permission android:name="android.permission.READ_NETWORK_USAGE_HISTORY" android:protectionLevel="signature|privileged"/>

Is this correct?

As this is possibly restricted, is there another way to determine the network usage of my application?

Has anyone been able to use the NetworkStatsManager Query methods successfully?
