Is there a reliable way to detect the app responsible for an Airpush ad? I noticed the other day that my Xoom's notification bar has started receiving Airpush ads (which is what it sounds like - push notifications that are really ads). I'm rather philosophically opposed to the idea of push-ads on my device, so I'd like to remove the offending application, but the ad doesn't give you any way to figure this out. Clicking on the notification star only gives you a link to the advertisement page, and nothing more.

I found Airpush Detector in the Market, but it doesn't seem to work on my Xoom, perhaps because of some Android 3.x differences. When I launch the app it says that no Airpush apps were found, but this is obviously not correct. Another option I've seen is systematically freezing apps using Titanium Backup until I find the guilty one, but that would be very time consuming and I'm not even sure if it would work.

I'm also aware of the permanent opt-out app in the Market, but I really would rather uninstall the app responsible for the ads (again, due to philosophical beliefs).

Is there any way for me to detect the origin of an Airpush ad?
Two points,

Firstly if you just want to stop getting the AirPush ads, AirPush themselves offer two ways that you can opt your device out of receiving the ads. Either:


Install the AirPush Permanent Opt-out app, 
or visit their opt-out page and follow the instructions to enter your IMEI to be opted out.


Secondly I don't think that AirPush is the only game in town doing this. I uninstalled an app a few months ago when I tracked down that it was the one spamming my notification bar. Its ads didn't look like AirPush's and it didn't show up with an AirPush detector. Didn't track down who was providing the ads framework the app was using, I was just happy to get that rubbish off my device, for an app I only opened once a month or so I didn't need that hassle. It may be that these aren't AirPush ads, but one of their competitors. That app I just tracked down by working out which apps I'd installed/updated recently, then glancing through the Market comments to see which one was full of users screaming to get rid of the notification ads.
