Android : How to add a Splash Screen fragment that disappear after few seconds

I'm trying to find a way to add a splash screen fragment that "gives a welcome" to the users, I mean I would show the logo and other stuff but passed few seconds this fragment should disappear automatically and then it should display my app (FragmentActivity with 10 tabfragments). So, how can I do this without creating another tab? I'd prefer it to be a fragment where there aren't shown Tabs nor ActionBar.

Could you help me? Thanks in advance.
