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
select android tools -> Add supported Library
there you see which supprt library revision id you have, in my case is 11
