How do I make an app/service for virtual/soft buttons for (Home, menu,Back, Search) always on top?
<p>I want make an app/service that looks like (Nexus One touch buttons)
for the navigation keys (Home, menu,Back, Search)</p>

<p>The buttons should always stay on top and send the command to the actually app thats running.</p>

<p>Someone have ideas and sample codes how to do that?</p>

<h3>Update:</h3>

<p>I also see and test an app wich show a "cracked display" always ontop
so that tecnic maybe shold be useful to always show the buttons on top.</p>

<p>Those function, show the button and catch the "touch event" and send the event
to the active program should be in a service module wich runs in background.</p>
