A launcher application is an ambitious project which requires a lot of time, effort and knowledge. Therefore it's unclear whether or not this project will ever get published.
What I have already done:
- Two screens, one of which at the moment is empty (displays only a wallpaper) and another which shows a full list of launcher activities.
- Wrote an Android Library just so that I could retrieve these activities ! They also auto update.
- Made application (actually activity) list functional - clicking on an application (activity!) will open that application (activity).
So if you were to compile and install this project on your Android device - it would work and you would be able to see your applications in an alphabetical order and launch them.
