I played around with the Google Play Games Services SDK a bit and it looks like they also have such a kind of dialog that is able to be on top of everything else (and even survives activity transitions). It's the "welcome" log in message that pops up on top of the screen.
I'm not sure where the code for this popup resides. You may want to take a look at the SDK code, though I believe you may not be able find it there since it could be part of a system component (Play Services system app). However, it seems to be possible to add a view to the window from within a service: http://stackoverflow.com/questions/4481226/creating-a-system-overlay-always-on-top-button-in-android and also http://stackoverflow.com/questions/12650463/getting-window-display-from-service-android The only problem is listening to onKeyDown from a service: http://stackoverflow.com/questions/3454710/onkeydown-in-a-service-global-hot-keys/3455094#3455094 I guess that would be the only thing where you need to implement your firmware customization in order to make that possible.
