How do I create a help overlay like you see in a few Android apps and ICS?
<p>I am wanting to create help overlays like the ones you see when ICS loads for the first time or in apps like ES File Explorer or Apex Launcher (there are more, but I can't think of them right now). Is this just a relative layout with one view sitting on top of the other? I haven't been able to find any sample code for doing such a thing. Anyone know how this is done or have any ideas?</p>
