Possible reason why the notification is not removed
<p>Notice that my notification icon is not always removed when my Service finish.<br>
Thinking about possible reason for this.</p>

<p>My service start some nested threads and the deepest one puts a notification with icon
in the title bar of the phone.</p>

<p>I can see that onDestroy() in my Service is executed on stop Service.
I run the mNotificationManager.cancel(setServiceRunNotifNumber);</p>

<p>I cant see that i miss running the cancel to remove the notification.
This only happens sometimes that the notification remains after onDestroy().</p>

<p>Are there something else I forgot?
In what situation would the notification remain after Service killed?</p>
