From Android Guys:
Lookout Labs has released a new application for Android handsets today which seeks to educate users as to what is going on inside their device. As many of you know there are many ad-supported networks to choose from and each brings about different types of advertisements, notifications, and other policies. Since they vary from network to network, each has its own level of intrusion or privacy concerns.
The new app, called Ad Network Detector, takes a look at each of your applications and tells you what’s happening on a per title basis. Compiled from information across the top 35 networks, the app then educates consumers as to what each can and/or will do.
The ad networks listed in Ad Network Detector:
