We noticed that the Jelly Bean OS has a "Show notifications" setting under the "App Info" section.

We have been implementing push notifications for our app, where we ask the user if they allow push notifications when they first launch the app.  

Since there was no global notification setting available in pre Jelly Bean (JB) versions, we had the notifications ON/OFF toggle inside our app in the settings menu.
However, since JB devices have a notification setting outside of the app that the user could toggle, now we would need to keep track of 2 toggles (one outside the app and one inside the app).

What is the recommended best practice for notifications on JB devices? Is there an API that we can use such that we know whether the user has "Notifications" enabled or not outside of our app?

Thank you.
