Cancelling notifications for app updates Every time an app automatically updates, it shows a notification. I find this ridiculous. For me, a notification means "something I should be notified about". The thought that I should be made aware every time a random app I never use gets updated from version 1.5.2 to 1.5.3 is so ludicrous that it makes me want to sit back in my reclining chair, take the backrest all the way down and think about how big the universe is and how small our lives are.

Is there any way to make Android not show those notifications?

(Note: I use CyanogenMod 9.)
Switch to CM10 if you can - you can then adjust notifications on a per-app basis.

Note though, that for your problem, the only way to prevent " xxx app has been updated" notifications might be to disable the Play Store from showing notifications, which IMHO isn't a good idea.
