[Q] Newbe Question-Download,Update,Compile&publish Android code

Hey Guys, I want to do a nice test to the Android OS. I would like to flash my rooted Android device with my own android OS version. I am doing so because I want to change some system app and kernel framework to act differently.
So I know I can download the source code with git, but can I open it with Eclipse? how do I compile it, and the most important question, how do I flash it back (with the changes) to the device?
I need to do it on Windows...I know it suppose to run on Mac\Linux, any free solution?
Thanks M

[Q] Integrating Android on an ARM Board

Good Day XDA!
I'm just asking a little help because i don't know where to start to.. I do have a project in school that will use ARM Board and Android OS. I have bought an ARM Board but I don't know where to start to in integrating..
1. The ARM board has already installed Android OS 2.2 but I want to install a higher version of OS. Can someone give me an advice or tutorials that can help me to upgrade or to build android for an ARM?
2. I've seen the article about building android from source but I don't know what's next after building the source from Linux OS and in building boot loaders and drivers.
3. What are the ways in making applications pre-installed aside from ADB? Is it possible to have a pre-installed app in a custom ROM?
That's all! Thank you!

Hello, I am New Here. How Should I Start?
So This is my First post on this forum.
I am Interested In Making Custom ROM for Android Devices. How Should I start? I already Have Linux (Ubuntu 13.10 x64) Set up for this and ready. And also How to Flash a phone. And does android have Dead USB Flashing method.
Device I have in mind is Sony Xperia Acro S. I don't own it yet.
I am a Symbian Developer. I am even have a Developer Status on DailyMobile Forum. I even have my own CFW (Custom Firmware). But since that Platform is Dying, I decided to Move to Android.

well you need to learn all the android basics, which can take a year to catch onto. And sense you've just started, you need to learn what root is and that sort of stuff. And to fix errors in source, you need experience with source, git, java programming and C++ coding. Also need experience with working with kernels and simple issues like fixing bootloops, and also know how to make device trees and kernel tree/repo and how to use github. And most of all you'll need a phone of your own to test builds, because the first time you build is never stable and it takes a while to fix things such as wifi, nfc, etc.
But you'll catch on Best of luck!

How to extract, customize and then flash again my cellphone ROM?

I Have a phone with a custom ROM and can't determine the phone model and can't find other ROM for it.
This ROM is somehow anoying because some ads popup and because I timezone is always set to China:
https://forum.xda-developers.com/android/software-hacking/timezone-to-china-t3704685
I need to know how to pick the current ROM/Firmware, change apps and configs (the bonus is to create a vanila pure android image) and then flash it again to the same phone.
I don't want someone write here HOW to do it. Just point me to softwares and tutorials. A start point I can walk by myself.
I have huge skills in Java and Ubuntu. Some skills in flashing images to NAND (bacause my work on Cubieboard) and already changed the ROM of my other phones and tablets.
My phone shows me this information:
Code:
Sony Xperia C6 Ultra
Android 6.0
Kernel 3.4.5-526212
[email protected]#1
Build number 23.0.1.A.5.77
Custom Build version
ALPS.L1.MP6.V2_GXQ6580.WEG.L_P69
I know this is not a Sony device but have no way to discover more about it.
Can I start from here?

Question about kernel, no noobs please :D

Hi, this is my first post on xda, but i was reading it about 4 years and now i have unusuall question:
I have phone - samsung callisto (GT-I5510) with cyanogenmod 10.2 rom (android 4.3.1), and kernel sources are available for it, but only below 2.6.35.7 since phone is ancient. This is "latest" and probably "fastest" android phone with qwerty keyboard (not including this unrootable new blackberrys), so i think that it would be nice idea to deploy lightweight kali linux nethunter installation for hacking purpouses. I had some problems with oficial installer, and i had to modify it to allow install on device with such small /system partition, but the problem is that chrooting to Kali Roling is not working, becouse minimal kernel version needed is 3.2.*.*
Question is: Can i somehow "update" kernel sources of this device, so i can build 3.2.*.* kernel? I have much free time and even more determination to do this.
