replacement for clock app

the least thing i like on the nexus one is the useless app it runs when on the desktop dock.

I already wasted a good day se开发者_如何学Goarching for the 3 topics below and failed to find anything.

1. Is there any replacement for it already available?

2. Is there source code for the original one?

3. Is there documentation on how to replace them?

1. Very Likely. Look in Android Market; I'm sure there's a desktop clock replacement app there.
2. Yes. look at DeskClock.git.
3. Yes. look at Intent.CATEGORY_DESK_DOCK. If you create an activity with an intent-filter that contains this category it'll show up in the list of available apps (the 'chooser') when the phone is docked.
