Best advice is to learn about android, learn some app development etc.
Unless you want to become a 7zip chef. That's easy.

Whats 7zip chef? Yes I know a little about app development with android. Android is java and I used to be Java certified since Java has been released by sun. Any other knowledge gap I need to fill? Should I learn more of linux stuffs?

:0 start learning "how to place the question in the right topic"...
i believe if u gonna make research and if u will pm some of the many developers here - maybe one that lives close to your area- he/she will help u out for sure with some details. i dont think they will release the details for public...otherwise use google mate.
Moved to Q&A
First best to learn about android in general. There are way too many people here who think applying a theme to a zipped stock rom makes them cool...
If you want to be regarded as a dev, stick to the coding side As you know java, smali should be simple to you..
Learn how to modify binary applications etc.
Don't fall into the lame "7zip to open the rom, drag and drop a few files, then re-zip" that some people (can they even be called people???) do... And stick away from theming something and calling it a rom.
It's just lame and not cool... But if you read up on how android works, you will get the hang quickly, and if you are knowledgeable about java, it should be easy to get going modifying things... Then you will truly join the "devs" and be one of the bunch

PFroyjr, das harshly put man, (OUCH) hey A.D. , the best way (in a mannerable way of saying wat pfroyjr jus said man) , is to do the old fashioned trial and error! The BEST advice I can give (because I will be using it also) is to find "Android Development for Dummies" , you can either download the PDF (legally or illegally is your decision) or go to a library and find it (download is your best bet, though.) It gives very in depth info on android deving, and is a great help! Otherwise, you can download a kitchen (go to theunlockr.com and search android kitchen, or search the XDA forums for one that somebody created) and start cooking lol.! Hopefully, ur gonna git a magnificent dish. I doubt that we use the same phone but you hav my support 100% from one dev in training to another

Sorry it was an off day LOL. The for dummies book is good but the biggest issue I see people learning dev is Linux. Pick up a good book on Linux and setup your pc/mac with the appropriate software.

I disagree...unless your doing something with the kernel you don't need linux at all.
sent from my uncyanogen modded epic 4g. with the key skips.
You still need to understand how the system works. Side note since you mentioned kernels....most newer ROMs have certain kernels that work and some that don't. The dev process is about learning how it ALL works not just how to theme a ROM someone else made.
No offense but any moron can follow directions on how to modify someone's work and not know HOW it works. True talent is by understanding and creating something new and original even if based on someone else's idea.
Hence I say learn Linux at least enough to understand

I agree with the both of them. Windows and Linux are like riding a bike vs. Riding in a car, its like 2 completely different ways of getting to the same thing, just one is faster than the other! Now my only objection to pfroyjr's statement is that http://www.cygwin.com gives windows the main pieces of Linux! I have yet to use it, but from what I understand, its probably gonna save you a couple of Gigs in PC memory vs. Partitioning your hard drive to dual boot or installing a virtual machin via Virtual Box! Unless you are talking about learning how to build a rom all the way from planting a seed to watching the tree grow, you probably don't need to know every piece of linux! Also, with the help of various things like APK manager (which breaks down the compiled XML files for editing using a regular text editor, rather than some complicated software) the sky is the limit when it comes to theming!
So, to sum up my statement, and kinda piggyback on what the other 2 said, if you just want a slightly different LOOK, then Linux is not necessary. But if your trying to take the future of ROMs to a whole new level, you either need Cygwin or, as pfroyjr said, Learn Linux!

Oh boy...I just love it when people start saying
"I'm building a ROM", "I'm doing dev work", "I want to be a recognized developer"
Then I make suggestions and I get "That's too hard", "Do you have a download link" "Cn u teac me hw mak a custm kernel?"
Yet they are totally unwilling to actually invest some time into these things and LEARN it.
Guy's Rome wasn't built in a day, and your ROM isn't going to be either. Look around, read, SEARCH SEARCH SEARCH. Download other people's stuff not just to Kang it, rename/re-post it under your name, but to LEARN, to figure out how it works, so you can UNDERSTAND. This isn't like a store, where you walk in and go "I want one of those, and I'll take one of them, and please get me that, where can I find this, etc, etc." Make little modifications, tweaks on top of tweaks, and keep doing that until it's soemthing new, soemthing different, and THEN post it. But please don't limit yourself, to what is "Easy" or "Comfortable", it's not the way to get anywhere with real development work, much less in life. Put some time into it, and some effort. I really do wish you all luck, but you guys have to stop looking for the easy way to get some quick credit.

@OP I know of zero performance modifications that you can do in XML, and if you are looking to use someone else's work and use that then start searching and make sure you ask before you use it.

This is very true, I'm new to porting and I'm starting with porting so I can learn the ins and outs of a rom so at a later time I can learn to develop, even in porting I've had to back smali and make some edits to get things working so sooner or later you will have to as well.. I'm currently reading a begginers guide on java for android.. Google is my best friend and I'm trying to learn as much as I can because I have an idea of my 'ideal' rom.. I can't wait for someone else to do it so I can port it and I know it will never be the way I want.. I'm doing it mainly for myself and I hope one day I can share with others

Best thing to do is get on the good side of a dev and ask them to teach you, I had great help from some of the best devs on XDA, but as above its not something you can just learn easily, I already had a pretty good knowledge of Java and XMLs etc before i got a smart phone lol, If you stick to it then you should get somewhere, Java is a pain in the ass though, editing .smalis is probably the hardest thing for a new dev

I don't really know if this is the right place, but this is as general as it gets. I've been messing around with my Xperia U for a while now. Modding ROMS and such. And when I mean modding, I mean very superficial, like just rooting, deleting unwanted files and stuff. I'm also fresh out of high school and I have quite alot of time before I go back.
So, I was hoping to really get to know the android system. It's always intrigued me. Is there a tutorial on creating kernels and developing ROMS?
Also, when you try to port CM for example to a phone. How exactly do you work towards fixing the hardware problems. Whats steps do you exactly do?

Thanks for the links.
One more question, suppose you're making a port of a rom from one device to another and if some of the components like wi-fi dont work. How do they make it work? Do they have to make drivers from scratch, or they find it from somewhere. I mean, I ask this, if there are no sources made available by the manufacturer.
I've been wanting to get into development more and more recently, and Android seems like a pretty awesome platform to develop apps for.
I ultimately want to develop a basis for a 2D OpenGL ES game that I can expand on, and also develop a chat client that works on XMPP and can detect when certain apps are opened and closed, and how long their open for.
I have... zero experience with any actual coding also, aside from maybe a few copy/paste edits on some random C++ stuff back in the day. Only real reason I haven't actually just "dove in" to Android development was because it looked... really confusing? Idk...
Is there any guides or learning methods anyone can recommend to help me out? I'm thinking I should just start from http://developer.android.com/training/index.html and just go from there, but is that the best place for beginners, or is that basically for people who have experience with some coding?

Another great resource for beginning Android development in the New Boston Android development tutorials http://thenewboston.org/list.php?cat=6. They cover topics ranging from the basics to making a simple game with OpenGL. And don't be intimidated by the time needed to learn everyone starts as a beginner when they learn something new but with practice you'll be writing great apps before you know it. The key is practicing with a positive attitude .

I'm your age too I do developing primarily on computers though and I have been doing that for a couple of years now. I can say that the best place to start is to learn a programming language. Most Android apps are coded using Java so, if you have some experience with coding learning Java would help you alot. But if you have little to no experience coding I would suggest you start off with something like C maybe even python but syntax is very different compared to Java so C is recommended. After you have enough experience with that I'm sure you can jump into building ROMs.
Good Luck!

my problem is I don't have a unique and practical idea. I'd wish I could come up with something that would be lucrative & beneficial but those ideas are limited and I wouldn't want to do something someone else has already done.
If I wanted to learn I'd get the latest Android Studio & follow some "Hello World"- type walkthroughs. I'd think YouTube vids would be helpful.
Then try to latch on to an open source project since I'd have an existing project to see how it's done.

I've always found Head First Series to be good. Try Head First C or if your feeling confident try Head First Android Development. But adding on to what jawz101 said the best way to learn a programming language really well is to do your own project, also, check out "professional" open source projects to learn the style and even some tricks of the trade.
