[Q] Understanding Android - tools needed - General Questions and Answers

Hello All,
I bought a Craig CLP281x netbook at Rite-Aid (ICS) specifically to begin playing around with Android and learning how to modify it. I got an update.img from the craig website, and rooted the device.
My question here is more basic than basic - I can open the img and look around inside with just an explorer, but if I want to try "rolling my own", do I need to use Android SDK to somehow create it? Or do I just start reading up on component parts and swapping them out?
Essentially, what do I need to compile my own update.img?
Thanks!

Understanding programming for rooting...

Hello, Developers!
Yes, I'm a Newb looking to get educated...
I have experience programming algorithms (VBA), but no experience with Linux syntax, nor Android app development.
In turn, I figure the best way to learn is to start from the very begining.
I'd like to learn, through step-by-step instructions (or someone working hand-in-hand with me), by begining with how to root a device.
I want to work from scratch by altering the existing files on my tablet, instead of using pre-packaged scripts, files, apps, or programs.
I have already installed (on my Desktop), what I believe to be, all the potentially necessary tools, such as: Android SDK, JDK, Eclipse, Android device drivers, Virtualbox, and Ubuntu.
So? What's next?
Which files do I need to start tearing into and examining to determine what alterations need to be made to enable SuperUser Root access?
Thank you in advance for your time and patience.

[q] dual boot t700

Hi guys,
I am new to the forums and just bought a Transformer Infinity T700.
I want to trial the system as is for a few weeks and eventually want to explore the possibility of dual booting to Backtrack Linux and using the system as a platform for penetration testing. Has anyone ever done this before? I can't see any related posts up here and have only read about backtrack being installed on older models.
Would greatly appreciate all feedback and any directions/threads I have missed to read for further information.
1. Use rabits' Ubuntu installation as a base
2. Replace Ubuntu parts with Backtrack parts (mostly the rootfs, and possibly the kernel, if you need a special config)
3. ????
4. Profit!!!

[Q] How Android kernel and Virtual Machine work

Dear all,
I'm trying to reconstruct the Andriod on my phone. So far i managed to download source code for Linux core including files like "mount, cp, modprobe,...", however I notices thete are other files in /system/bin like "am, pm, ..." which control the other layer of Android OS. How can I download the source code for these kind of files. Also in framework we have "am.jar" which seems to have direct relation to Java VM. Maybe it is better to also ask how Java VM works on Android. I do not ask about general knowledge because more or less I know how it works. Basicly I need to know which files are related to the process of running Apps on Android and what they do.
Best wishes.

[Q] Newb using Android SDK/Genymotion

I am interested in buying a new android and would like to run the OS from a few android phones in a virtual machine. Everything is installed, Android SDK, eclipse, Genymotion, as well. After loading one of the VMs that are already available, what interested me was how could I load a particular kernal for a phone that I would like to buy.
For example, I downloaded the rom for the ZTE Open C (firefox OS). How would I go about converting this to a VDI or OVA? Not sure even which I would convert it to. Could somebody even possibly point me to the correct faq, did some searching but not really sure what to search for so only coming up with how to root your phone.
Thank You

[Question] Can we root a virtual android device?

So couple of days ago I installed Android Studio and set it up. Then one of my friends said that you could actually create virtual android devices inside of Android Studio. This got me exited. But a question popped in my mind. I thought, "In order to do experiments and gain vast knowledge about android in general, I have to root this virtual phone." So that's what I've been thinking for the past couple of days. Can you root a virtual android device that's created inside of Android Studio? If yes, how? If yes, how do I boot into recovery mode and stuff related to it? If yes, can I install custom ROMs?

Thank you reading through this and I hope that I will get all the answers for all my questions!
