If your a developer please read

On android, is it possible to have an app limit another apps of certain services? (like for example if i had "app A" that i wanted, but it requires gps or access to my contacts to install, and (app A) has nothing to do with those [like if a wallpaper app required access to my personal info], would it be possible for an app to limit "App A" of services and take away its ability to use the undesired service?) i guess im asking if this is plausible or not... If it is, Do you know anyone who would develop this app? I bet i could get a lot of users supporting this idea.... (A lot of Users want the ability to do this) I bet this app would be a huge hit, and a must have for most knowledgeable users...
Thanks for Reading

There already is one. The power control widget that comes with your phone can turn gps on/off, along with brightness, WiFi, and account syncing along with a few other things.

I literally mean limiting service to an app.

So more like a firewall for apps to stop them accessing different resources?

Well, yeah. When I first used the power control widget, my GPS, WiFi, and Sync was on because of Google Maps. Occasionally, when I download a new app, GPS or WiFi will turn on and I just turn them off. You could also try whitelist/blacklist apps which might be able to help you.
