I recompiled for Android a Delphi application I wrote for iOS with my son a while ago, to navigate videos of Mario Bros(TM) levels. The idea is you select a level and get a video, rather than having to search on Youtube. Technically, below is a page of a multi-tab application with a header indicating the level you are looking at (3-5 in the image) and the client area covered by a web browser control pointing to the URL of the specific YouTube video, extracted form an in-memory data structure:

  ytUrl := MarioWii[level].Items [Item.Text];
WebBrowser1.Visible := True;
WebBrowser1.Navigate (
'http://www.youtube.com/watch?v=' + ytUrl);

(Oh, did I mention the same code works on iOS ;-) This is the screen-shot:
