Android book for custom ROM building [closed]

Question

I'm looking for a book or other resource which gives me a good overview over the Android system.
Things I'm looking for:

• how to define preinstalled apps / widgets
• how to add drivers for sensor data (e.g. accelerometer)
• how to configure display parameters

Every recommendation is welcome as I didn't find anything yet.

Answer 1

Sorry this is a late answer, but recently I've stumbled on a very helpful set of videos on this subject from Marko Gargenta -- it was very helpful to me understanding the different portions of android and how to get started with creating a custom ROM image:
