[GUIDE] Custom ROM development for the rest of us [In Progress]

*** THIS IS NOT JUST ANOTHER EFFORT TO CREATE YET ANOTHER CUSTOM ROM***
Though Android is opensource, a lot of things are unknown regarding ROM development/modification. There are many custom ROMs available for Galaxy 3 (and also other phones) and lot of people are flashing them and making their phone more responsive, productive and faster; but very few people actually knew how to go about developing the ROM.
What I intend here is to find out and document correct way to build ROM for our favorite Galaxy 3, which is very popular in India.
The goal will be to develop the ROM from Android source + Drivers from stock ROM while documenting the process so that large number of people can contribute to the development.
I will shortly update the posts with what I have done.

looking forward to what you come up with
Making one aint difficult keeping it bug free might get sometimes

Thanks rudolf895
I have experience in Android SDK and NDK development, but I am a noob when it comes to ROM development. Thats why this effort.
I have fetched android source using repo as well as I have also downloaded source for I5801 from Samsung open source website. After this I will look into extracting drivers from stock ROM and successfully compiling it for Galaxy 3.

hehe, cant wait to see what you come up with, sounds promissing btw... i am also willing to help whereever i can, whereas this wont be too much in this case i guess.
good luck and thanx...

TY ..!
Thanx alot
This would be really helpful to alot of members here

interesting ! waiting ....

I applaud your thread, I myself was thinking about such a concept.
I wanna help, but I cant do that much (basic knowledge of C and basic/little knowledge of linux and adb).
I think first there should be a list of basic stuff. Like compiling the sources, extracting factoryrfs and co from your phone etc... Sometimes if you wanna start doing something and you dont know the basics you get scared off because of their apparent tremendous lack of knowledge.
I'd probably start dabbling if somebody told me how to compile the sources.

can you also specify your work environment, toolchain and such stuff, so anyone can start from zero? there is a kernel building vm image with all tools by sztupy somewhere on the forum that is eventually of interest, and there is also an extended version containing eclipse and some more tools for full android development:
http://forum.xda-developers.com/showthread.php?t=882010
hope this helps somebody...

Did you try using it? I think the scripts are specific and cant be used by us (without altercation)

no, i have absolutely no idea of kernel compilation and all that advanced stuff, but i guess it can be adapted for our use

Yup...me too in waitin line...Now i can say i dint made a mistake by buying it...

Starting out development help

I am looking at learning how to develop apps etc for android but have no idea where to start. would be much appreciated if anyone could give me any pointers of where i can get the necessary information in how to start developing and learning the language required in order to start.
I only have limited experience in C, C++, HTML and CSS so I could do with some information that would be suitable for myself to start.
Thanks in advance for any help that anyone can offer.

ROOT...

Hello everyone,iam new in forum.
Can anyone tell how to root "karbonn A3".Iam trying to use z4root,gingerbreak,universal androot.
But no one work.pls tel how to root my phone.
Thanks in advance...

Purity sure you'll want to post in the Q&A section for your device, or ask a mod to do it for you. Otherwise you'll get helpfully natured people like me that don't know a direct answer.
To help answer your question though; try adding the word 'solved' to the beginning of your search quarry and adding 'similar:website.com' but replace the website with sites like this one. Put the issue or thing you want to know more about between and you'll likely have a good start to your answer. Example:
Solved root epic 4g similar:forum.xda-developers.com
Hope it helps with your task. You can also replace the "similar" part with "site" to search only one site with google. And certainly replace the "epic 4g" part of the example with your device. This is the format I use to learn most new and old things on the web and then I refine it from there. Hit me up if you need more examples and I'll try to help in my free time

Hi again, its been a little wile and figured I'd check up on ya
Did you happen to root your device?
If so can you post links to the guides you used?
I ask because I'm currently starting a project within the main guide I'm writing on XDA (link in signature) to hack and root Android with another Android and a USB cable, no PC required style.

Do you have experience in OO programming otherwise start with this tutorial: http://www.ntu.edu.sg/home/ehchua/programming/java/J3a_OOPBasics.html assuming that you are able to do basic operations like assigning values to variables etc. otherwise start with a basic java tut on google.
For a really basic start you could use something like ConTEXT: http://www.contexteditor.org/downloads/ . After installing a java sdk and adding the java/bin folder to your path (environment) variable you can set up Context to compile and run your opened java files.
I myself quickly switched to Eclipse: http://www.eclipse.org/downloads/pac...pers/keplersr1 . This has many more features like auto-complete/suggestions etc. If you want to create apps for the android dalvik platform you can download the ADT plugin for eclipse: http://developer.android.com/sdk/ins...lling-adt.html . From there you can download the android sdk and start using the android build platform.

Youtube and stackoverflow will be your two best friends

I highly recommend to read through XDA University forum.
There are many useful guides such as:
1. [GUIDE] Setup Android Development Environment on Ubuntu 13.04+
2. Where to learn programming/coding
3. [GUIDE]GUI - SignApk Jar File Tutorial to Sign and Align APKs
And check the App Development Forums > Coding Discussion, Q&A, and Educational Resources forum.
E.g. Free Online Mobile Development Courses (Java, Android, etc.)
