How can I tell which Android Support Library v4 revision I use?

I can see in the Android SDK manager the version installed on my computer (in Android SDK manager), but usually a project uses its own copy from the libs folder.

Is there a way I can tell which version is the android-support-v4.jar being used in a specific project besides the file date?

Any method is considerable - by code / eclipse / file manager

Solution
    1. in eclipse package explorer right click in your project

    2. select android tools -> Add supported Library

      there you see which supprt library revision id you have, in my case is 11 enter image description here
