I posted this in that Google+ thread, but would be interested in what folk here think:
So what's the proper way to do this now (stop apps you want from being killed yet never show a notification)? Is it possible?
There are several utility/monitor type apps that the user would want never killed. But to have a persistent notification gets in the way of 'normal' notifications (aesthetically) and makes the status bar and notification shade look very busy. Would it not be better to allow the user to set that persistent notifications don't show for selected apps of their choosing?
You can also tell the system your service needs to be restarted asap with START_STICKY or START_REDELIVER_INTENT.
