Deving

I am going to take it upon myself to learn to Dev. Not because we don't have great developers now but because i would like to contribute to the community.
I am curious though, how did some of you devs get your start? Was it just tinkering around, familiar background or something else? Also I've been doing some reading up on this matter of making roms and was wondering if you guys like raver, dsexton, racing and others would support me if i need help or have a question about something?

What would you like to dev?
Do you have any programming experience?
If yes, do you know Java, Linux, shell scripting, git, C/C++?

Actually first off I'm sorry i forgot to mention your name fb In the op your a good Dev to. As well as bh and airfluip.
To answer your question. i would want to dev roms and learn to make apps too. I only have experience in c++ but i would need to relearn it. i took visual basic and c++ in high school which was 8 years ago lol

For now I stay stick to learning Linux and how to compile programs from source, or you can learn Java and how to make android apps. As far as working on kernels or building roms from source it might be a bit too complicated for you right now.
You can also consider learning edify which is basically shell scripting. You can control what your cwm zips do when you flash them. It's what I've been working on lately so you can take a look at the source code here:
http://sourceforge.net/p/teamacid/installer/
Check out the updater-script and aroma-config files in
/META-INF/com/google/android/
I have left a lot of comments to help people understand the code.

if you do have some experence

I am still 14. I started tinkering with my G1 last summer, since then, this is the progress I have made.
I have learned:
A lot of java, (You need this because basically android is based on 10 % linux(kernel and boot stuff), and basically, android's main system is 85% java. Apps, dexes, frameworks,libs,everything else is java, swap, ext4.
Some c++(the other 5% off the sytem)
shell(all internal unix command line programming)
What I still need help on...
_
------------------------
git(if you want to help with AOSP and kernels and more)
More in depth stuff.

+1 to FB for Linux. It's a great place to start. You learn facets of scripting/programming along the way. Get a bit up to speed there & learn to compile your own kernel for your PC. It's not too difficult unless you start modding the code.
Good luck

Thanx guys I'm going to look over this material this weekend and report back. I know it's just the weekend but I'll be some what more knowledgeable about what I'm doing

You feel old? My 20 year reunion is coming up this summer...
As for learning to DEV... It's a huge learning process. I started with scripting a couple months ago, and looked into attempting to build a ROM, but I do not have a Linux machine and my POS windows machine won't run linux properly to do much of anything with it (both installed as a dual boot and in as a vm). Keep reading and learning...

So far I've been reading up on xml and java. I think i will try to develop an app before i take on a ROM. I will try to make an app that can theme our phones in some sort of way.

You'll need ubuntu as an operating system to start off with....

And the cm source..

Hah, I wouldn't mind trying this out myself.

Along with a decent computer and basic terminal skills in linux.

You will also need Eclipse classic

I thought about it, but then I went to this site and decided it was beyond my skill set. Start here.
http://developer.android.com/index.html

Dude that site is for app development for rom development u need to head to this site
http://source.android.com/

Do I need to know a programming language at all? I know a little java but not enough to do anything with, I am very familiar with ubuntu and linux in general. what would I need to get started?
Thanks everyone for all your replys!

Sorry. I pasted the wrong link. Was in a hurry. Thanks for posting the correct one.

Ohh...u will need a from kitchen also....and programming language.... ummm Java is imp for starters...
Sent from my LG-P999 using XDA App

Is there a certain kitchen that you would recommend or which one do I need for G2x?

Depends on what ur going to build from.......are u going to build from stock or CM sources.....according to that u should download a kitchen but I guess there is a kitchen which is very gud for the g2x...

I was planning on building from stock, and mainly just starting out with themes etc for now.

So u will need the stock source for gingerbread

Themes are a great starting point. Learning which apks control what is how it begins, learning how to manipulate how it looks turns into manipulating how it performs. Smali and Java are languages you need to be able to read at the least for the OS itself, C/C ++ knowledge would be nice for kernels. A basic knowledge of Linux is required if starting from pure source.

Want to learn Linux (shell)?

I saw this tutorial linked to from the Raspberry Pi blog:
http://linuxcommand.org/learning_the_shell.php
You can use this thread as a Q&A. There are a few users here that will be glad to help you, especially since you're taking the initiative to move away from the GUI, one of the best steps you can take on a *nix computer.
I recommend you actually try out the commands as you're following along in the guide. It'll stick in your memory better that way.

I started learning Java (having known a little PHP beforehand) from a book called Absolute Java by Savitch. You can buy it pretty cheap used. I have the second edition.

Here's some good information if you are learning about using a linux console:
http://unix.stackexchange.com/quest...ce-between-a-terminal-a-shell-a-tty-and-a-con
Bash is fine but I recommend you try out zsh. If you get the configs from GRML (http://grml.org/zsh/) as a start you will find it to be very comfortable since the stuff you've learned about bash will carry over and it will seem to have a magic understanding of what you want to do. As you read more about it (man zshall) you will find it has more features and options than you could imagine a shell could have.
Take the time to learn your way around a good console editor too. I prefer Vim for a variety of reasons but emacs is also very popular. There is a bit of a holy war about which is better so it's hard finding unbiased comparisons between the two but the wikipedia page seems to do a pretty good job (https://en.wikipedia.org/wiki/Editor_war).
Congrats to everyone learning the command line. You will find some of it a little unintuitive at first if you are used to the windows way of doing things but most people that learn can't imagine how they got anything done before they did it.
Good luck and feel free to ask specific questions here. I'll answer. I love spreading the good word.

I wanna get into android development.. where to start?

I found some books... basically learn Linux/android developing, i wanna get a good idea/knowledge... create ROMS, Kernals, just anything that has to do with android..
Where do I start?
Sent from my Nexus 4 using Tapatalk 2

one thing at a time buddy. Start by learning some Java. From there you'll be able to move into app development.
You might be able to do some rom manipulation without being able to program, but knowing how apps work from app development would be helpful.
Ill leave the kernel stuff for someone else to answer.
Sent from my GT-I5500 using xda app-developers app

I agree - start with learning a programming language.
Many are pretty similar in concept/structure - so once you understand the basics, you'll be able to branch out as you will find you need to.

Start with java and learn the basics of app development. Then jump into some theming and modding. This will help you familiarize yourself with system files and such. Finally, the most difficult of all, coding and kernel work. This will require a bit of C, C+, python, and a couple other computer languages. You'll mainly be working with C tho. Start at the bottom and be patient with your learning! Good luck!

totally agreed. i want to get into developing, too, rooted my ROM firtst, getting into the Terminal of Linux/ubuntu, decompile, modify, compile random apps, Theming the system UI... build your way up and see what you can do. One thing i have to say: You will need A LOT of time. most of the things are trial and error, the best way to learn how things are working.

What kind of development do you want to do? Applications? If so, google 'java tutorials' and you should find good materials on Oracle's site and others.

Would it be worth buying a raspberry pi and learning the python language.. to get started in learning?

Yes, for the apps Java is fundamental, for kernel and other part of the OS i think it is required C.

A good resource to check out is WWW.programmersinstitute.org. There are step by step videos for setting up your computer to program and then projects to work through with the instructor. The last time I checked it was free!

Absolutely this. Java's the best way to go. Go download NetBeans IDE (Integrated Development Environment) and look up some free online tutorials. That'll get you started.

If you're more inclined towards kernels / ROMs, better to start with C, and then learn JAVA. Kernel is mostly C and android framework is mostly JAVA & C++ (For ROM development, you can make do with framework C++ if you know C)
For C, read Kernighan & Ritchie, for JAVA, any basic Java tutorial should do. Most of all, start coding from your first day - without trying things, you'll never learn programming.

If you decide to go into application/game development, I would highly recommend to try libgdx. I have been using it for 2 years and I am very happy with it.

[Q] about knowledge and jobs

Ok so I'm really interested in android development and I'm gonna get some books to read about them. Books that I'm gonna get are C and Java for general OS knowledge and to develop apps. So I'm wondering what jobs can I get in future??Apart from these:
-Working in Google[i made this an exception at the moment since its not easy to be the top]
-Making apps and sitting at home
-Making mobile apps for companies
Hope to get some good replies, cause I don't wanna choose the wrong path and have my life ruined/jobless in future
PS: Is android OS/kernel 100% on C only?? no C++ or C#? also are the apps 100% Java??thanks!

Learning Java and C++ isn't going to ruin your life even if it turns out to not be what you wanted. It takes like, a semester to get the basics down - this isn't four years of your life. You can even teach yourself.
Writing code is like writing English - most people can learn to do it. It's the creativity and ability to problem solve that makes a difference.
Just learn C++ or Java (flip a coin) and see if you like it and if it's a kind of thinking and problem solving you're good at or even like. It's not going to take ages. It's like taking a cooking class to see if you like it - you're not going to be a master chef or even a good one at first - but you won't know unless you try. And even spending a year and not wanting to go on isn't the end of the world.

Yes, Android Kernel is actually a modified Linux Kernel which is 100% written in C. No C++ or C# is involved. Android OS is written in C, C++, Java.
And yes, all the android apps are written in Java and there are places where XML editing is performed.

Jobs will be mainly based on your education and experience. Just do stuffs that proves your experience, add it to your Resume, and if employers are convinced you'll get the job. There are countless opportunities for Android development.
