I have a question about the Android action bar.

We are working on the Android action bar. The final feature I'm trying to do now is to automatically show the action bar below when I touch it anywhere in the activity after about 10 seconds of loading the app.

I think we're using show() and hide(), but can we actually make it like that? If possible, please give me some advice on which technology to use.

I'm posting a question because I haven't got the hang of it yet when I'm touching this and that for the first time.
