Resource usage

[Android Question]

Is there any app or functionality which tells you which apps have permission to use your account/accounts. And not only accounts but other resources too like camera gps ... Also is there app which alarm you or deny some apps to use some resources.

This is mostly the domain of root apps. However, unrooted Jelly Bean devices can use App Ops. It doesn't catch all permissions, but does a pretty good job of identifying and allowing you to disable most of the ones that might be abused (which may of course, break the app). It is available from Google Play store or an a system activity, if you are using a launcher that enables them (like Apex).
