Can't get permission BIND_NOTIFICATION_LISTENER_SERVICE for NotificationListenerService

Question

I created an app and added a java class that extend `NotificationListenerService'. Everything should work fine, but I just can't get to permission BIND_NOTIFICATION_LISTENER_SERVICE. I added it on the manifest, but when I check for the permission with:

        if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.BIND_NOTIFICATION_LISTENER_SERVICE)
            != PackageManager.PERMISSION_GRANTED)
    {
        Log.d(TAG, "permission denied");
    }
    else
        Log.d(TAG, "permission granted");

but I keep getting permission denied. I know that this permission isn't a "dangerous permission" so I don't have to ask for it from the user. In the manifest I declared this:

        <service android:name=".PcNotification"
        android:label="PCNotificationService"
        android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
        <intent-filter>
            <action android:name="android.service.notification.NotificationListenerService" />
        </intent-filter>
    </service>

and it still doesn't work. I also implemented the function onListenerConnected but it never called, so it means that my service never gets connected to the notification manager, probably because I don't have the permission BIND_NOTIFICATION_LISTENER_SERVICE

I just want to know how to grant this permission to my app.

I just can't get to permission BIND_NOTIFICATION_LISTENER_SERVICE

You do not need to request that permission. You need to defend your service with that permission. You are doing that in the <service> element via the android:permission attribute.

I know that this permission isn't a "dangerous permission" so I don't have to ask for it from the user.

Then get rid of the code that is requesting it from the user. It is unnecessary, and it will not work.
