1. Authenticating components of the OS

I'm looking for a way to authenticate the kernel, display drivers, and
the Java VM and its libraries. One way I imagined doing this was to
perform a checksum on /dev/mtd/mtd1 (bootloader image) and /dev/mtd/
mtd2 (kernel image), but opening up either of these devices into a
CheckedInputStream (for CRC32 validation) results in an enormous
crash. Not only does the device stop responding, but the android debug
bridge crashes and no longer recognizes any attached devices until
Vista (go figure) is rebooted.

Can anyone suggest a better method for validating that the Operating
System has not changed (i.e. The bootloader and kernel are factory
defaults?)

2. Classical layered architecture to Android architectur - how?

Hello fellow developers.

I and 3 of my fellow students are doing a school project, writing an
Android app. We are taking a bachelors degree in Software Development,
so we have studied Design Paradigms for desktop applications, from
Craig Larman' book, "Applying UML and Patterns: An introduction to
object oriented design and analysis".

We usually do a domain model, a data model, and a design class model.
Ending up with 3 to 4 layers. such as a technical layer(sql and
network connections), a domain layer (business rules, and domain
objects), a controller layer (controllers for managing domain objects,
or usecases), and a UI layer.

We are used to building our applications this way and can't really
wrap our heads around the optimal way to design the architecture for
an Android application.

Question 1.
Is there any reading material, books, articles from google or such?
(We need to reference it in our final report)

Question 2.
How do we go about it?
- Do we put the controllers in a service, with the domain layer, and
handle the tech layer with "Handler" classes, for separating it out
into different threads?
- How do we make the connection between a service and an activity
then? Via AIDL?
- Is an activity only meant for gui, or should it contain controllers?
- Do we incorporate broadcast listeners into the service, or do we
bind the service to the broad cast listener once it gets a message
which needs action?

Hope you can enlighten us :) Any reading material is much desired.
