There are two activities, Start Activity is composed VideoView and Main Activity(listview) overlays on VideoView. Because I don't know how to overlay Listview transparently on videoview at one activity. That's why I used two activity.

```
StartActivity(videoView) -> MainActivity(Listview)

```

The problem is that when I finish this app using back key, only ListView is killed. So I have to press back key again for killing videoView. I have searched all info, but I can't find out.
