How long will a non-clearing notification stay?
<p>If my app fires a notification and marks it as non-clearing (i.e. tapping it does not remove it), what will result in the notification being removed?</p>

<p>Would I be right in assuming that if the app is shut down by the memory manager that this will cause the notification will be removed? Or will the notification persist even if the app is recycled?</p>

<p>My app needs to show a persistent notification, and I need to understand whether I can set it up in the app, or if I need to build a service to manage it.</p>
