Apps Dock.apk

[ECFfighter7232]

Im very new to TRYING to build apks, and im wondering if someone can point me in the direction of where i'd find the source code for the dock.apk that is on the Droid X... I'm trying to make something in AppInventor that involves the dock.apk and it says I need to find a file in that source code.
any help or guidance is greatly appreciated

ok, so I wound up finding the script I needed using logcat to see what came up when I activated the dock.apk now my question is, since the apk is started by a magnet, where in the code can I change something to forget the magnet part? is that even possible?
