So, I've been a member for a while, and I've done my fair share of using everyone elses ROMs on my phones, starting from HeroC, to Moment, to Epic, to OG Evo, then on to TMo phones like the MT4G and Nexus S.
Now that I'm back on Sprint and rocking this beast of an Evo 3D, I'd like to actually CONTRIBUTE to the community. I give you Dev's/Chefs mad respect for what you do, and I'd like to be a part of that as well.
So, here's the actual questions for this Q&A thread: Is there any special programming knowledge I need to start cooking roms, or starting to dev? Do I need to know code? Do I need to be fearless with my own device? (lol) Is there a *For Dummies*-ish site/thread/forum that would be a good idea to read up on?
I realize that there are probably a million threads like this, spread all over the interwebz and these are PROBABLY some "OMG NOOB SEARCH" questions, but in my opinion the best place to go for information is directly from the source
Believe or not...the best source of info IS searching...not us...learn the basics...adb, java, XML, start small...learn Linux and learn, learn, learn....all great developers and chefs...are self taught...because what you learn on your own...you learn to ask questions to yourself,,,for yourself...it is either in you or not..a passion for knowledge in programming and or modifications of system cannot be taught for the drive..because if you search first and learn by doing with the tutorials...then and only then can you ask the right questions..
^^^ I've never seen so many ellipses. :s
@OP Yeah, I'm trying to do the same thing. I've picked up a book at B&N titled "Android Apps for Absolute Beginners", by Wallace Jackson. It's pretty up-to-date, and includes Honeycomb bits.
It's readable (as opposed to reference-able), and it's taught me quite a bit. I recommend you have a super basic background in Java (any object-oriented language would be good, but all the code in the book is Java and XML), something like Introduction to Computer Science or similar would do fine.
Good luck with that, and lemme know if you find any resources I should know about.

It's a bad habit.. I commend you on what you are doing...my background was I taught myself 8086 assembler for the at class back awhile ago. Nobody would help so I digested book after book and line after line of assembler and a language called Force. To make a Long story short, I wrote my first commercial assembler library with over 1600 functions! That's a lot of code. I was one person that wrote it, the manual and support over compuserve. I was very proud of and I believe no other language library even came near it. It was at the time the most feature rich one available with another library called Funcky II with around 1400+ functions. Both were C callable, large memory model. Today's hardware do not need that crap. Then eventually went into programming full time a little after that. So I speak from experience. It is one thing to ask for guidance and another for specific items. Every good programmer, without exception was self taught..yes they went to college for computer programming or others like me that did not..they shared a common theme which is self motivation and the discipline not to quit. I once asked a very good programmer what is the secret to becoming a great one and his reply was simply code and code away. A very good reference for programmers is in fact the library source. It is invaluable. Hope this helps a little bit. I did tout my horn, yes, but you needed to get a background so you would not think I was as my dad used to say "speaking out of my a?s".

Nice, programming in assembler is no small feat. If you're familiar with Linux and Java you should have no problem figuring ROMs out. Dsixda has a kitchen he posted in the Android Chef's section that is very useful and apktool along with either WinMerge or Meld can be used to learn from the different ROMs.
It was a labor of love. I just seemed so cool in asm. Actually, what I want to write is a decompiler for the android with near perfect retrieval of code back. I seen the engine in smali and just do it for the heck of it. It has the parser in it..but I don't know java that well. Can't even write a hello world..) I was darn good in Delphi with windows and would be more comfortable with that. If somebody wrote simply a lexical for the small/ Bali output then that would all you would need for that type of program. I did not study java's reflection that good and it's another route. I want to give others who want develop the fun and passion I had. This was a hobby when I started. Years later, that hobby never left me. I respect the **** out of you and other developers out there, no matter what phone, tablet or computer because yes you are programming..you are giving something of yourself to others. Non programmers really do not know that developers for all the bugs and crap that comes with it...it is our soul, hearts and emotions that go into every line..every file we put out.
This you don't learn from a book..this you learn by making come alive what is inside our brains.
Thanks for the responses guys! Much appreciated. Looking forward to diving in head first!

Have fun! I took xHausx suggestion and went to chefs central and it will help all new developers. Last night, went to the android forum section in there..hit last page of it and went backwards reading page by page and in that night investment..I found resources that are invaluable. I recommend you do the same. One thing I should tell you many out developer wanna bees out there...the only thing that sperates the ones who are and not is the simple fact..if they had a problem, they did give up. This may sound simple..but when you get frustrated...it is easy to throw in the towel.

Recently we have seen HD2 Android developers discontinue their builds LOL! Interesting to note that all are going to school? Its unfortunate that the Cooking on HD2 Android is kept much of a secret...what I suggest is if they are discontinuing then they should share their Cooking knowledge. Of course most of the pple aren't farmilia with Linux stuff lol! however I am sure that with a good tutorial and the tools you are using, pple will be good to go.
Not to hide words, I am calling out to Pongster, Shui8 and Darkstone to now share their knowledge for the good of the community.
Thank You.

I Agree
nothings hidden.. check htc-linux, freenode
I see what your getting at but I dont think its fair to say that anyone is "hiding" anything.......
All the information you need is out there but the problem is that doing something like this is realy quite difficult if you dont already have a good amount of knowledge on the subject.
Its one thing to learn from a tutorial but for something like this you would really need to start from scratch and the learning curve for a beginner taking on such a project would be very very steep.
You are right though, if more people took up these sort of projects then the world would be a better place
I just wish I had the time / mental capacity to do it myself.
Yeah, I see what you are saying. I guess one just has to step up to the game. Create the mental capacity and take the plunge into the deep. I guess the learning starts again then, but I just wish these guys put up something for the taking rather than just dropping off projects and run....
So I came into this with previous programing knowledge, but not knowing java. I've read a book on java, then the programing android book.
So from those of you that actually write apps for the android platform, what do you think is the next step? Just get to it already? Start using eclipse and its built in tools to get started and learn by doing and googling as I go along?
Is that the way most of you have got your start? Any other books I should pick up?
Thanks

Moving to Q&A
I am getting started too, am beginner / intermediate java programmer with little experience. The android site has some nice resources.
Developer.android.com ... Resources tab: look at the tutorials. The Hello World is a nice intro. You will install the Android SDK, eclipse, write a simple app, and seeit in action using the emulator. I have done Hello World and Hello Views.
I'd also appreciate any advice / guidance from more experienced droid devs!

I've done that stuff so far. I've also played with the layout manager to.o. I th.ink I might start out making a sound board app. That seems pretty simple to do.
I'm just looking for some advice as the best way to precede
You're on the right way. The next step as a developer is just to develop software. Thats it.
You can look at some books and resources on the Internet to learn basics.
But I think the best thing to do is to imagine a mini-app (very simple, for example a calculator), and try to make it from scratch.
You'll learn how to search information and this will be less boring.
You can also create new projects from samples of the SDK, they are quite interesting.
Write code! Seriously. Screw the books (or you can waste money like me). I am sure that if you start building something like I have coming from a similar background, you will know what books to pick up when its time.
If you are a coder, just make up a project and learn Android in the trenches by figuring it all out as you go. That said, it would be invaluable to read up on the platform itself (the Android dev site is great) as programming for it is a bit different than what a lot of us are use to.
It's fun after you figure out the build environment on your platform. Also, if you are like me you live and die by text editors. That said, I have learned to finally embrace both Eclipse and Java thanks to Android.
EDIT:
I am now getting a lot of mileage out of Creating Android Applications by Chris Haseman. This is only after wasting money on books I wont read or that teach me to do things the wrong way. I was only able to make an informed decision after hacking together my first serious app. This book is packed with nuggets of insight from a and immediately answers questions I have from my experience with the ocassionally sparse documentation. I would highly recommend this book and because of it my future code is going to be very solid without the "did I do the right" feeling. <-- typed on g2x in Browser
Your right, I think I have enough background to dive in. I was playing around and created an app that plays mp3's when you click on buttons, didn't take long at all. Next thing I want to do is create a splash screen, and I took a quick look to see how to create buttons that are a picture and text, similar to the buttons in the google api sample.
Having fun with it so far.

i understand this question has been asked in similar ways but programming is quite broad so hopefully i can get a personalised response to help zone in on my learning.
bit of information about me:
ive been using computers all my life whilst doing a little bit of code tweaking for a variety of things such as; games(hex editting) web coding and even a bit of excel macro work.
i currently have no plans or commitments as of now and wanted to use my free days to learn something new that ive been intrested in since i was about 12 years old.
im looking for a base or a starting point in learning coding... i understand jumping straight into coding apps and things is way out of my reach but i guess i have to start somewhere! Im very much intrested in customisation and the ability to customise as much as possible on phones, games and applications but i have no idea where to start...
ive been looking around and people recommend learning all sorts of languages from:
php/css moving up to java
straight to java
python
c#
c++
c then progressing into c++
but id rather get an answer from a community that is notoriously skilled in the developing area so much so that i feel this is the best place to ask!
if there is anyone who also wishes to help me personally in helping me along the way and giving me some advice then please pm me as id be so grateful to have someone there to help me.
thanks in advanced for your responses im looking forward to learning and hopefully starting something that will be a major part of my life from now on.
Well, since this is a mainly Aneroid development website, and if you are interested in aneroid, I would just jump straight into Java. That's what I did at least... to learn Java just google "Beginner's guide to Java" or something. Hope this helps.

i was hoping for more input then just one person, i would like to know what others feel is the best way to go about it so i can build up an idea of peoples opinions to see what i feel is the best strategy of learning.
i appreciate your input ballarous =)

What are your development plans for? Do you plan on donning an apron and becoming a rom developer or do you plan on developing apps? You're setup will differ between the two but either way grab yourself a few good java books but understand it applies to Android differently than regular java. Learn the fundamentals of java, it's core rules etc but study googles open source api to see how you implement your phones system into regular java format. Here is a link to the Google source for developers (not source as in the source you sync to build Android, source as in how to implement phone apis into that source) http://developer.android.com/reference/packages.html
Here's some general app development guides that will broaden your understanding http://developer.android.com/resources/index.html

From my experience...
It probably does not matter where you start... I personally started with web based languages like VBS, and javascript, then jumped into c++... I completely avoided Java until recently.
VBS or Visual Basic is used for excel macros so you already have some experience under your belt. It should be pretty simple for you to apply that same understanding to the different syntax of Java.
Ok, I want to make this as straight forward as possible, but give you the details you are curious about.
Let me start by saying that personally, I, and only I, have been creating this conceptual idea of Android on the desktop since March 2013. This is my soul here, and I have been, for over a year, trying to bring this to light for everyone. But that is not the easiest thing to do.
I have page after page, PSD after PSD of ideas written out all over the place for how Android on the desktop will work, full of redesigns and structures. But it is going no where for one reason.
I need coders.
I have 4 - 5 people preparing soon enough to get started on developing. My main coder and adviser, has found something, which I cannot speak of here, that makes developing this idea so easy and pretty smooth. We have a lot of this mapped out already, but we need a team to make this happen. You must trust that what we have planned here will be the next big thing. This isn't just a knock off, this is what it is meant to be. Do not worry that "Android was created for phones and tablets" as we have over looked that minor idea and moved past it already.
What we have planned will work without a doubt. But we need you; rom developers, those who know what they are doing and have knowledge in python, c or java, either one.
I have someone offering me to put this on their hardware which will be released in the fall, I have a few people interested in this, but the problem is, no one can touch it because it isnt in a workable form. Maybe a minor form, but not enough for you to touch.
I want to show you a fraction of the work I've done, which I've posted on XDA
I would also like for you to check out the G+ group and join if you have G+.
Also if you are a ui/ux/icon designer, by all means please help me out. This is a pain to do by myself.
But, please contact me and I will bring you in with the small group of people we have, we would be more than happy to have you.
Thanks for looking.
Hello All,
Will try and keep this short: Am an old time developer, since 1979. I was self-taught, as a kid, never one class. The weakness there is that I never learned most of the terms.
So when learning new languages, it was harder since I didn’t have a reference point. i.e. may no longer be used, but I created “linked lists”, just never knew they were called that.
Anyway, I never got past using C and WinSDK. And I learned just enough Perl on the fly as I needed it to create some backend parts to some of my apps.
I am desperate to start a new project, preferring to do it on Android first. As hard as I looked for LOCAL developers with serious programming experience, and preferably some Voice SDK experience I failed. I tried Craigslist and Meet Up. Nothing.
So I need to do this MYSELF. Or at least start it and come up with the alpha-prototype on my own.
After all that explaining, what’s the BEST (and least expensive) means I can purchase to teach myself programming an Android device?
I always loved forums, we’re talking back when NEWSGROUPS were the way to go. Because out there was always someone who knew…and was willing to share their point of view.
Currently using a PC-Windows environment, so any IDEs in that arena would be preferred.
So any help, any direction would be so appreciated.
Many thanks ahead all,
Sergio
I would definitely recommend grabbing Android studio and looking through Androids developer docs. If you're familiar with java all you really need to know is the Android framework and how everything works together (lifecycles, passing data around, working with various sensors/hardware, etc).
Android studio is free so no cost to you there. If you're not familiar with java there are tons of good resources online

Hi!
I agree with @blackangus, i started programming for android with eclipse at that time and some tutorials i found online.
In my experience is a little bit frustrating at the beginning because is has some hard to understand concepts if you come from low level languages.
you can try to follow a basic lessons to start understanding the different parts like,
1) Views ( it cost me pretty much to understand how views and activities work)
2) Networking and async threads (restfull services calls and json manipulation)
3) Play services (push notifications, account registration and such)
this was the approach i took and it helped me a lot, i hope my humble guide helps you too.
5 years ago I got my intro to Android via Android App Inventor: http://appinventor.mit.edu/explore/
Good intro to Android concepts but drawing pictures instead of writing code still can't produce professional apps.
So I dove into learning Android Java. Nice...
My background was in C ; I never quite figured out C++ and have heard since that Java is superior anyway, written for OO instead of adapted from C.
I still program plenty of C for Android NDK low level code.
Before C, I did various assembly/machine languages, including the first CPUs in the mid 1970's and in early 80's front panelled a simple OS into an old PDP-11/05 to use an Apple clone keyboard and a "TV Typewriter" type 6847 Video board I built...
Now I'm wondering about iOS Objective C. Much more money still it seems in iPhones/Pads.
I am a newbie too. My background is microcontroller programmer, so i use C very often. When i start learning android programming, i begin with learning java and eclipse first, after i got the OOP concept, i begin learn to use android API and Android Studio....when we start from low level language, learning Java is easier... Java basic first then android API....
I am a serious coder, usually working with enterprise applications at my job. In my experience, if you need to learn something new, it is better if we get help from some friends or professional trainers. Saves us a lot of time and trouble. If you want to learn the basics of OOP and are going to build something, I suggest you get help of a professional trainer. You will be clear about the subject matter easily and with your experience, you will achieve progress within no time.
Wow. I don't feel so bad now. I'm and old geek too. I'm looking at trying to develop a simple game for Android. My last coding was in 1988 using COBOL. I'm a System Analysist but most of my experience was in medical systems and Digital Radiography. I'm basically a College Freshman.
Thanks for the information.
Can we keep this thread open or create another for Q&A from you wiz kids?
A funny note: I was involved with Search and Rescue in 1979. We were a driving force to get SAT phone's going but our budget only allowed for 2 satellites that year. We tested with a fellow driving in California while talking to us in Milwaukee. We only had a 20 minute window , then had to wait till the next.flyover 3 hours later. We've come a long way. Let's keep the momentum going!
