Replacing Android's Launcher App before compilation

Question

I want to have my own Launcher Application for Android

in other words , I want my own Application to run directly after booting , instead of the Launcher app as I am not running Android on a Mobile phone , and I don't want Android's Home GUI

also I want to change the app in the source code , before compilation

I have tried to Simply replace files under "/packages/apps/Launcher" with my HelloWorld App then running this command "mmm packages/apps/Launcher" but It didn't work

So any book/tutorial/advice that covers this point ?? Thanks in advance

Answer 1

Android was designed to be so modular that it supports what we want without any tweaks !! maybe little tweaks in your program only

Android doesn't go for a specific Launcher app in predefined location and run itin fact you can have multiple Home Screen installed .. each App identifies itself somewhere in it's code that it is a Home App Then Android in booting decides which home App to load Demo @ http://developer.android.com/resources/samples/Home/index.html , which is included in the SDK samples too
