FileNotFoundException after every build

So, after import admob and google play services in my project after every build I get this error:

Image link

both services work fine (banners, interstitials, leaderboards, achievements…etc).
I googled a little bit the problem but didn’t found anything useful so if anyone has any clue about whats going on and can help me would be nice, thanks.

EDIT: I’m using Unity 5

go to android sdk\extras\google\google_play_services\libproject\google-play-services_lib\bin\google-play-services_lib.jar

copy this and put it in your plugin\Android folder of project
