Developing help - Motorola Atrix HD

Hey guys I've been flashing and rooting and unlocking for a couple years and I'd like to actually learn how to build roms, apps, ect. Where can I learn?

I think the best place to start learning how to develop apps is the official android SDK with adt. but if building android is what you want then take any Linux distro and start reading about official aosp. information for both are publicly available from Google.

Linux is, like, mac or something right? I'm on Windows 7 so am I screwed?

buy a decent sized harddrive and install ubuntu or mint linux on it. then you can dual boot win7 and linux like me. Just start tooling around with the linux command line (terminal) and learning how to think like a geek lol. Then take someones rom, and take it all apart. look at what makes up a rom... the apps, libs, frameworks, etc. Setup a build environment on your linux box, download the official source code from google, and try compiling it until you can do so without errors. at that point, if you want to start actually deving, you need to know java, cuz that's what source code is in mostly. there are alot of source code modifications avaiable on xda, try merging one in with the source code and rebuilding it and see if it compiles... if not, it''ll tell you where the error is. just play around with it, practice, ask questions, but actually jumping in and just making your self do it is the best way

Thanks What size hard drive do you recommend and what rom should I dismantle?
(I'd thank both of you but apparently there's a thanks limit I didn't know about...)

each aosp build is about 30 gigs and Linux takes almost no room no matter which distro you use so when it comes to the size of the HDD it is all about the balance of how often you want to clean and how much you want to spend.

That. I'll add that, on my PC, Linux uses 20GB of space...but I also have two distros installed on the same partiton with one being a chrooted build environment.
Roms use around 20-30GB as is, another 15-20GB is used up when compiling, so you want to reserve 40-50GB PER ROM to be safe.
If you do buy a hard drive just for compiling roms, BUY A SSD...solid state drive. That and RAM will help you the most. I'd expect just a SSD alone would cut my current build times in half.
I'll tell ya that without any Linux experience at all that you're gonna be in for a nice fun time.
Now, if you just wanna write apps, LEARN JAVA. You can do app writing on Windows and test on an Android Emulator (or your phone for at matter). No Linux necessary for just writing apps.
That said, if you want to get into compiling roms, you've picked the right place because I will help you if your serious. If you ask me a SPECIFIC QUESTION I'll give a specific answer. Don't ask "How do I use git?" cause I might not reply very nicely. Ask me "How do I update the kernel with the Dev Teams latest updates and I'll give you step by step instructions. I'm about to have 3 different roms I'm gonna have to compile. So if you just wanna pick one of them that isn't PAC, feel free to be the compiler of it. So far I've had multiple offers for compilers and only @Youngunn2008 has stepped up and actually started doing it.
EDIT:
//I started building custom roms about a year into using Android. Had to. Nobody else on my device could (or would?) and I wanted more roms, simple as that. All I did was CM7, PA, and a few others, but it got me to where I am now. Kanged from Quarx's repos. I owe much of my Android knowledge just from watching his commit history (and for keeping us up-to-date with proper drivers). A good Dev Base is a good place to start from, just remember to give proper credit and thanks (and ask permission if it isn't open souce -- that's a big one).

You guys are the best. I'm gonna start looking for the equipment asap. Although I need to learn how to write code, so I'm gonna go through Java.
@skeevydude I'll definitely hit you up when I need serious help
P.s. where do you recommend I learn Java from?
Thanks everyone!

I'd click Thanks but I've seemed to run out of them (seriously, 8 thanks a day? Really?), so thanks. I can't read script at all (It's like looking a spanish, knowing it's spanish, and not knowing what it says) but I'll try to stumble through this lol

my suggestion is to download the SDK and start following the my first app tutorial. I did not understand code at all until I did that and then things started falling into place and making sense.

Couldn't tell ya where to learn Java from -- I don't know it. I'm starting to learn it myself...meaning today....but it really depends on the weather on what I can for the rest of the day -- lost internet for most of yesterday during a thunderstom and since another one is rolling in I might have to shut my machines down. Also why I haven't been on a whole lot the past 2 days. After today its supposed to be clear skies ahead.
I've just been lucky cause even though I don't know Java, its still pretty human readable and easy to figure out what I need to do when I merge code.
For a bit of help Java=Apps, C++=Kernel/Hardware. Not necessarily 100% true, but for the most part it is.
If you wanna get into writing apps for making money then start with Java....the only reason why I'm starting with Java over C++. As much as I'd like to learn C++\Bionic to help with bug fixes for the kernel, hardware libraries, etc, I'm flat broke and can't find a decent job -- Java and a good idea could fix that. Combine my current situation with the fact that in 10-15 years I won't even be able to do my current line of work (construction is a young man's job) so I need to buckle down and learn a new trade that doesn't involve 8-12 hours work in the sun, crap pay, sore body at the end of every day, and no real job security or benefits.
If anyone reading the above is thinking that I'm thinking I could be the next App Millionaire...I'm not. I'd be happy just to break the poverty line (1-3 thousand a month or more than 18k a year)....cost of living isn't that high in Arkansas luckily. I'd hate to live in NYC\Random Big City where a crappy 1 room apartment's rent is a high as a high-end middle class home here.

I would also recommend Java. I'm in an internship developing an Android app for a local company and it's pretty straightforward. I'm not very good at building GUIs, but I can manage the flow of code fairly well and I'm learning as I go.
I didn't know you were in construction, Skeevy... With how skilled you seem in all of this I would have thought you'd be from some sort of tech trade.
I've been looking into ROM development myself but it seems a bit overwhelming to me. I have always been interested in how operating systems are put together and built, but the most complex thing I've ever done was patch together a Linux server box for gaming and hosting an old website I had a year or two back.
I have worked with Linux for quite a while and I now run Ubuntu as a primary, no dualboot. It kinda sucks to get used to the lack of applications but I would much rather have the stability and responsiveness of a Linux system. Plus documentation is everywhere so anything is usually fairly easy to fix/get working.
If you guys could post some websites/threads with some tutorials or further reading so I can know what I am getting myself into, that would be awesome. I have always hoped that one day I'd be able to help you guys out with getting bugs squashed and features added.

GUI's are a pita to me as well...but then again, I'm barley mediocre at photoshop
I used to make good money doing what I do, and I liked doing it. I was doing custom wrought iron fences and gates -- the kind you see on high end lake houses and such. Since around September of '08 that line of work went from 30-50 hours a week to nothing....NOTHING. We've had maybe 6 jobs in the past 5 years nothing. Every job I've had since then has either gone under or I was let go because I was the new guy and they had too much costs in labor. Combine that with 2 years of 10 applications a week and not getting a single call back....almost applied and McD's a year ago. Asked how much I'd make and the manager said maybe 4 hours in a 7 day week for the first 6 months to a year....F THAT. Wouldn't have even covered the gas to work...no point in a job that you'd make -$15 for two weeks work....that's negative 15.
As far as my trade and tech are concerned -- I've always been naturally skilled at almost everything I've done. Not bragging, but that's always how things have been for me. My biggest weakness is I have crap social skills -- I have a bad tendency to see everything with pure logic and over analyze things, completely missing things like sarcasm and subtle hints. It wouldn't surprise me in the least to find out I had Asperger's.
Rom development and rom building (kanging) are two different things entirely. If you're already running Ubuntu (preferably 12.04) I could have you building a rom in no time at all.
Its nothing more following the official build setup guide (assloads of copy/paste )
making a directory for the rom
open a terminal to that directory
"repo init -u https://github.com/PAC-man/android.xml -b cm-10.1"
"repo sync"
". build-pac.sh mb886 -jX" where X is the number of cores your PC has
Do something else for a few hours
Check PC -- if the rom fully compiled then you've just kanged PAC-man
To update, go to rom's directory, "make clean", step 5, step 6.
Adding support for other roms is as simple as seeing what other devs\kangers did in the project's vendor directory as well as in the device/common-device directories. It really is simple once you've done it a few times -- first time or two can be a real b*tch.
My only real gripe with linux is some of the apps either just don't seem finished or are just good enough to do the job but look like crap. For me, other than gaming, I've been able to find a suitable replacement for all my common, everyday needs from emulation to video encoding to word processing.
As far as tutorials go....I just use Google, XDA search, and rootzwiki.com search...between the three I can pretty much find anything I need to know. Power searching is the unwritten requirement in all the tutorials I've ever read. Being able to scour the net for odd bits of information is a necessary skill to kang or dev roms.
//Lack of search skills is a reason some of us power users get upset and pissy around here...myself anyways...I can't tell ya how many help questions I've answered where I LITERALLY copy/pasted the error code in the help post to the google search box in Firefox and the FIRST LINK the fix....also why I don't answer the same question more than 2 or 3 times....search just our forums and you might find the answer. :whodathunkit: (// isn't at you, my mind likes to rant in the mornings )

I'm in high school but I REALLY don't want to work at a fast food place, so this like a good way to earn so change. Once I get out, this will (hopefully) become more of a hobby for the next 25 yrs as I'm training to become an Electrician. Then when I'm done and in the early retirement that seems to come with many people in that field I'll hop back onto this. I also second that idea with the idea of website tutorials lol.

Electrician is a good trade to get into. I wouldn't mind being an electrician actually. Especially since I know enough contracters, house flippers, and landlords that are always needing electrical done and hate paying the electrician (they can pretty much write their own check cause you GOTTA have that LICENSE to touch ANY wire)....why I always built my gates to run on a 12V solar setup (more reliable and I don't need a license to mount a panel and hook it up to a car battery; not to mention a grand cheaper).
Look, I'd post some links, but the best links are banned from a site like this where ethics matter. I'm broke so I can't afford the ebooks if ya know what I mean...hint, hint...find good looking book with positive reviews, google search "name of book .epub", ????, profit.
//see my above post for a quick glance at what McD's offered me....TL : DR version....negative 15 a week cause I factored in a thing called gas money.

Root Security

I work in computer security in my day job, and while I am interested in all the extra features one can get with rooting your nook color, I can't help but cringe when I see people installing unsigned, unvetted software, closed source which performs modifications to their devices. At least with Cyanogen's roms, you've got a fighting chance to look at their code in git.
How do we handle security when you don't know what you're sticking on to your tablet? How do we know that someone hasn't modified the keyboard app with a keylogger, for example?
Well, it's pretty much like everything else. You can trust the mechanic who works on your car or the electrician who rewires your house or you can fix it yourself. You probably pick those guys based on reputation or credentials. Do that here. Don't install software from somebody you don't feel you can trust unless you have the ability to check the code yourself.
That's just one of the reasons I'm happy to see the CM Team getting on board.
I guess what I'm getting at, is I'd love to be able to see exactly how they 'rooted' the system, and each step that takes place during the process. The first root that came out, I got about 50% there, but hit a minor roadblock and lost interest. I do appreciate all the work that goes into this, and I was surprised at how many people would install the root without thinking first what they're putting on their device. I know 99% of the time, people are honest and trustworthy. However, all you need is one person to compromise a server, change a zipfile, etc, and you're in a world of pain.

[Q] Hello, I look forward to developing with you.

Hello, I am new to this forum so I suppose I will give a brief bio. I earned an Associates Degree in Computer Science from the Community College of the Air Force while serving on Active Duty as a "Computer Programmer" from 2004 to 2010. Most of my duties on the job involved website development, server side scripting and databases. I started learning network engineering and security in the past 3 or 4 years. I'm familiar with being a go-to for fixing an unrelated FUBAR project from a random language where you have to just google the syntax and methods until you get the results your boss asked for. I've also dabbled in .NET and so on.
Anyway, it is safe to say I know enough to be dangerous or better with everything from legacy assembly code to the trends of today while I have no clear specialty of expertise at this point. I am going to use the Post 9/11 Montgomery GI Bill to go back to college. I should know what I want to do by now but it is a unique opportunity where I may as well do any one thing as another. I like to avoid personal conversations and keep it about the development on forums. I got a nook color 1.01 and came here for some tips on rooting it, now here we are. I am interested to know what particular needs there may be for an intermediate developer that has no strict preference with where I begin just as long as I don't need very expensive new hardware, unless I wanted it anyway.
So, hello and nice to meet you. I look forward to finding a way to contribute.

You can start from building yourself a most powerful i7 (Ubuntu, or whatever your flavor) Linux box your $500 can buy. Generate the tool chain(s) for emulator/TI OMAP36xx SDK. Pull every piece of code published by TI for OMAP 36xx. Study all the free Android/Java/JS development books you can find, subscribe to all Android development forums and to GoogleGroups of the topics and irc channels.
Then, start building the 2.6.32, 2.6.35, 2.6.36 kernels for Android 3.x.
XDA Devs is not exactly the place where the Gurus of Android development explain and do tutelage for newbies, it's the place where they show their results. Read in my blog http://fineoils.blogspot.com about developments for NC and other tablets in condensed form, plus about stuff that is usually of no big interest here. Start from approx. Feb. 2010, this will take some time, lol.
Thank you for the outstanding advice. I have an Ubuntu machine on a first gen Phenom quad core which was starting to collect dust that would be perfect. When I get setup I need to find out what some good starter projects would be. I bet that someone here has a need that has been overlooked because the pros are busy on larger projects and I could take a stab at it. Any ideas?

Welcome! I'm new to Android, so I can't help with anything too deep just yet (used linux exclusively for 7-8 years, so I'm catching on lol), but I can give you a list of a few common issues that people are having that I haven't really seen solved yet.
1. Touchscreen bugs out sometimes, requiring a quick trip to standby and back to fix. Happens to me regardless if I'm OCed or not.
2. System seems to randomly shut off and/or reboot for many. Has happened to me a handful of times, almost always when doing something cpu intensive, like launching Winamp or opening too many DolphinHD tabs.
3. Wifi for many people seems really flaky. Mine works fine 99% of the time.
4. Youtube doesn't like when you log in, requires a cache wipe to relaunch.
5. Screen sensitivity gets weird near the edges. There is an adb method to force a blind recalibration, but seems to have widely varying results.
6. Pull up menus on many apps ends up with white on white text making it unreadable.
I have no idea if any of those are relevant to you or if anyone else is already working on them or not. Hell, some might already be fixed in Froyo or even Eclair. Those are just a few things I see many posts about. I should mention that I'm on 1.0.1 rooted with no other tweaks. I also have a horrid case of strep throat and have been quarantined in my room alone on heavy meds for a few days, so I could be way off or babbling. Anyways, welcome to the forums and sorry for typing so much. I know I'm not nearly the novelist that that blog pimpin dude is. ;P
This is all good information and I appreciate the reply. I hope you get well soon. Strep throat and strep meds are no joke and you are extremely lucid all things considered, so don't worry one bit about that. You are running the same system that I have so please feel free to keep in touch with me about any issues, and I will let you know if I find a fix.
If you have some spare time I'd like to ask you some questions about using Linux for an exclusive PC; I keep juggling it with Windows rather than taking the time to find a fix for common petty problems like running Netflix. Right now my lazy fix for that is virtualboxing Windows.
Thanks again and feel better!

Anyways, welcome to the forums and sorry for typing so much. I know I'm not nearly the novelist that that blog pimpin dude is. ;P

[OT] Learning the ins and outs of java.

I'm a sophomore in high school taking computer science. (please don't judge me because of my age) Our school is making some major budget cuts, so sadly our video game programming and design class (the only other higher level programming class offered) got cut and this will be my last and only programming class at my school (well there's a possibility that it will be brought back in my senior year, but I'd at least like to stay fresh over the summer and next year). I don't know much about java to tell you the truth. I know how to use loops, conditionals, arrays (1 and 2 dimensional) and arraylists and most of the basic variable types (off of the top of my head, integers, doubles, booleans, longs, and strings). I've made some very very simple apps such as whack a mole and craps, but the gui class was provided by my teacher.
My question is this: is there a good, preferably free online program that teaches you the basics of java (especially related to the gui) and possibly some more complex programming?
I appreciate any help. thanks.
P.S. Please forgive me if this is too off-topic, but I really couldn't think of a better place to post this. Hope you guys will be able to help.

Go to Youtube.....search for a guy named "thenewboston"
He has a whole series of java programming lectures that saved me in my Advanced Java course in college....

Thanks! I'll make sure to check him out!
I was in the same place as you a while back. The best way to learn is by trying to make something you want.
Before jumping into any serious programming you need to learn a few more important concepts. Methods, classes, objects, and more on those. You need to understand how it all works before going further.
If you have any questions feel free to message me or hit me up on gtalk. I'll give you some tips, ideas, and some source code of apps to dig into, if you like.

the basics:
http://download.oracle.com/javase/6/docs/api/
http://www.eclipse.org/downloads/
now go to some university's entry level cs website and do some of the programming assignments.
but if you know control flow, some data structures, types, etc. just program. there are a ton of simple things to write. for example, write a calculator that has an add method that just adds the two arguments, then write recursive multiplication, factorial, and exponential methods that only use add (or other methods you wrote). it's simple, but decent recursion practice. i could give you a ton of simple programs to write.
oh and pay attention to what everything actually is. read and understand what static, private, public, classes, objects, etc. actually are and their purpose.

I should have added, I have a basic understanding of methods and classes, and we are just getting into objects now.
Thanks for all the responses guys! really appreciate the help.
also, if you guys have any suggestions for simple apps that a beginner like my self could make, fire away.
I applaud you for beginning a hobby/interest in programming early. Currently I'm a 2nd year student at a university for Computer Science so I have a very direct understanding of Java. You should know that structure of Java (for every day use) is different than that of the Java on Android.
Download the Android SDK: developer.android.com/sdk/index.html
Follow all the steps of installation and DO the Hello, Android (World) app that it gives you. Make sure you UNDERSTAND everything on the screen and in your main class.

Perhaps you would like to have a go at Missionary Java or K9 Java.
I can sell you my 'Programming with Alice and Java' textbook...if I find it. It has all the intro stuff. First it uses a program called Alice to teach you how it works, and then it teaches you to do actual code. When I find it I can tell you where it leaves off.

[Q] Best I.T. field?

Hi, I'm coming to this forum to ask my question 1. Because I know there are a lot of tech-savvy people here and 2. Because I'm on these forums a lot.
I guess my general question is: what is the best IT field to get into now? I really like programming, but I read a couple or places that its projected to go down by 4% from now til 2018ish.
But I read elsewhere that computer engineering is growing rapidly.
I'm 19 years old now, about to start college soon and want to pick a good field in. Something that can defenitely pay good as well.
And I know there's a lot of cross knowledge about IT.
But what's the best IT field tp get into?

I am a Network Engineer. I think it is a pretty good field, if you don't mind the late nights, and other things. The Networks are the furthest behind right now, and we need competent Engineers to build and run them.
i agree with above..
I agree, however getting companies to spend money on talent and equipment is hard. Its like years ago before companies spent on backups. They wont spend till it bites them.

Correct. Working for a Vendor, I see this all the time. It is hard to tell a company that they need new switches every 5 years, especially in this economic time.
The big pusher will be IPv6. That is forcing a lot of companies to look at their infrastructure today. They have this feeling they will be left behind if they aren't IPv6 ready by the end of this year. At least on my view of things - that is the only reason Enterprise side businesses are buying new Routers/Switches.

The problem with Network Engineering is there is no degree for it. It is a lot of self knowledge and self learning.
Take your Juniper Certifications or Cisco Certifications. Buy books on BGP, OSPF, IS-IS, IPv6, etc.....
Download software to run labs at your house....build a cheap Cisco lab as well.
GNS3 is a good Cisco network simulator.
I know this isn't the advice you're looking for - but I'm going to give you the advice I wish somebody gave me when I was 18.
Screw the market predictions, screw the salary ceilings, screw the skill demand. Find something you really dig and the rest is going to fall into place.
I spent 7 years as a software developer. I got paid far more than I was probably worth, had loads of perks, and life was good. Problem was I didn't get any satisfaction out of writing code anymore (not sure that I ever really did). It took me a long time to figure out, but in the end you're going to spend 40 hours (or often 60 in tech careers) a week doing something for the rest of your working life. Your quality of life is going to improved much, much more by genuinely enjoying those 40-60 hours each week than it will by bringing home 90K/yr. Believe me.
At 29 I took about a $25K/yr pay cut and "started over" as a web/ui designer in a new company. It's one of the best choices I'd ever made - I just wish I'd made it when I was much younger. My life would have been much easier.
Isn't a degree worth more than a certificate?
I'd rather spend more time in school getting a degree rather than doing it quick and getting a certificate.

I know, people are always telling me that. And I'm always open to hearing peoples opinion. I actually would love to do a field in IT... Just don't know what exactly I want. Like I said, I like programming, computer science, etc., but there not gonna need alot of programmers in the near future. My friend is actually a network engineer and makes good money, but I know he'd rather be doing something else.
As for me, I've been doing jack **** for the last two years. I would actually love to spend 40 to 60 hours a week keeping my hands and brains busy.
So I might look into Engineering.. cause that's what it looks like its going into.
I know if it's something with tech involved, I probably won't love it, but I would like it. Better than doing anything else.
2 of the fields I'm looking into:
Computer Engineering Technology (Networking)
Computer Programming and Analysis.
your inputs?

Depends. The way I see it (being in the field) If you want to stay on the Engineering side of things and don't have an interest in being Managerial, then Certs + Time In the Field = More Money than Degree.
If you think Certs are the easy way - then you haven't taken any of the tests. If you want to get into Networking you have to have Certs. Then get a job working in a NOC, or for a smaller ISP. Then you work up.
I'm a field engineer so I go to clients' sites and support their IT/resolve their IT problems.
Being a jack of all trades really helps, and having the right mind is a godsend.
Being able to think on your feet to come up with solutions with very few resources, having high google skills also helps, and a resourceful memory for niggly little problems.
In my experience computer degrees are pointless, industry qualifications actually have value as they bring benefits to companies such as partnership programs.
Whats going to be more appealing to customers? "We have 5 engineers with degrees" or "We're a Microsoft Gold Partner" see what I mean?
The more qualifications you get the more you can ask for in salary.
Contracting is where the real money is, you can get paid stupid amounts of money for doing simple things.
I was getting £200 a day on one contract to just create new users and run reports.
so what you guys are saying is,
it's better to be certified in many fields and work my way up rather than getting a degree in a specific field?

Yes. And pick a field you enjoy too.
alright. I appreciate your advice.
When I try to pick my major in college, I'm listed 3 choices ( All Computer Engineering )
Cisco Specialization
Microsoft Specialization
Cyber Security and Digital Forensics Specialization
Out of all those three fields? which one would be the best to "specialize" in?
They also have two other fields available which are computer programming and analysis, and computer information technology. Too many people in CPA and they won't need them in the near future. CIT is too broad. And I don't really know about that.
Another approach which might be a bit different is if you can scrape up the money to go to a conference or two, that may give you some insight on the different areas of IT and may help guide you on what you may or may not like. Virtualization is huge now due to the whole "cloud computing" thing. Microsoft/Active Directory/Exchange-type environments are widely used, so any experience there should guarantee you a job and an employee in a company or a solutions architect if you can design that infrastructure... or support for that type of environment which would be a first step in that field. I always believed that if you're the type that's into programming, you'll know it early on. The hard part like others have said is choosing what sub-field you want to specialize in (or that you enjoy).
No matter where you go, things can get pretty deep. I know a few people who chose to be project managers and make a good living not knowing anything technical - just the logistics of it all.
If you are going to get into general IT - to start with stick to CSCO and MSFT.
You can't go wrong with acquiring certs from either. While it doesn't hurt to know both - at some point you will find you either like to design and support the network (CSCO). Or you like to do AD, LDAP, Server type of stuff (MSFT).
If you wanted mine on which to chose of the 3 you have, I would suggest trying to get internships at each one, to see which you like. College is expensive, and you don't want to have to go back multiple times, because the degree you got wasn't something you liked.
Take an Internship at a smaller ISP. This will give you a chance to check out both the Network (CSCO) side of things, and Systems (MSFT/Linux/BSD) side of things. Most larger companies (Fortune 500) will split it up like this anyways, as it is too much to wear both hats. So you will have your team of Network Engineer's and your team of Systems Engineers/Admins who generally all report up to a single director/vp.
Don't really have the money or the time to intern. That's why I came seeking advice.

Two fields spring immediately to mind. Computer Forensics and Computer Security.
Both growth industries and interesting too i imagine.
I'll try to make this my last rant here.
I know you came here asking for advice - but I hope you understand that all advice is necessarily autobiographical.
A lot will disagree with me here, but degrees and certs are worth little. Good instruction is infinitely valuable, demonstrable skills are infinitely valuable, and you can get those in post-secondary schooling, but the piece of paper itself will only help you get your first job, when you have no experience, and the person hiring you is either too lazy to verify your skills, or is unable to do so.
Probably the best developer I ever hired was entirely self-taught. The worst was one of the most highly-educated individuals I'd ever interviewed.
I don't know where you got your information about the software development market drying up but I think you're making too big a deal out of it. I cannot fathom a future in which a good software developer's skills are obsolete. You'll have to switch languages/environments many times in your career, but if you dig coding, just go be the best coder you can.
I implore you, try out some different stuff in school and stick to whatever it is that gets your motor going. Don't worry about a 4% market downturn or what industries might grow. Nobody can predict more than 5-10 years away, and you're going to be doing whatever it is you choose for 30-40 years.

[Q] Self taught or not?

Just wondering how all you experienced developers on here started out. I know you have probably been asked many times before but I am genuinely interested.
I am by no means any sort of developer. I first came to this site about two years ago when I first learned of rooting. Prior to that I had no knowledge whatsoever of developing or programming.
However I cant keep off here. Is it something that can be self taught. I would really love to delve into this so that I can start to have a little input into what goes on here and even if its just testing at least I could maybe be of help to someone. I have picked up little bits on how things work but my main question is where would be a good place to start self teaching??? It is becoming somewhat of an interest for me.
Any pointers would be hugely appreciated.
Thanks

Well for roms, check if your device is supported by Dsixdas kitchen, if so that's a great place to start tinkering...
If you want to really start making changes to things though your going to need to learn to code to some extent...
Read and search, read and search...
Good luck

Nowhere near an experienced developer, but with a couple of apps and a ROM WIP, the only thing that taught me was xda-tv
Learning to me is just when somebody puts a puzzle in front of you with no clues or guidelines. But you are surrounded by 50k people that you may ask questions (xda).
I just keep trying to solve the puzzle and if I really don't get something I just ask xda.
That's just how I learn. Its how I've always learn. Just dive into it and rip it apart. Think as logically as possible and listen to some cool dub step while doing so for extra learning points.
