[Q] Becoming a dev. - General Questions and Answers

NEWBIE...Im fairly new into the developing world, but I have a solid background in anything computer orrientated. I started with a droid x, rooted it, and have never looked back. I'm taking java classes and learning as much as I can about programming. Any helpfull advice for someone starting a career/lifelong hobby in this feild? Reading a lot of books and blogs, but any other resources would be greatly appreciated.
Thx to all the professional devs out there who make it a fun digital world to cusomize!!!!

Lets start by using the search function.
This question gets asked and answered several times per week...
Personally i would skip the books.
I started by an idea in my mind what i wanted my app to do and taught myself through tutorials, stackoverflow, irc and lots of google...
Start something small, maybe an app that plays a single mp3 file.
Now you think, how can i choose different ones -> make a file explorer.
And so on... kinda like reading wikipedia, you start with some topic but end up in another topic far away ;-).
Thats if you want to program apps... there are lots of types of devs.... apps, roms, themes, kernel...
Now don't say you want to learn everything .

Thanks & more
Thanks for being the first to reply! And also for the info. I've done a little programming, vb and java, but am more interested in the rom/kernal side of things. Seen the vid before! Awesome!
I tried searching the site for what I'm looking for but unsuccesfull, figured the best way to get forward in this site, and get specific info, was to post a thread in one of the only places I could. Reread the rules and newbie posts, and figured out the reasons but they dont bother meat all.
Guess I'm looking more of an answer to this question, from everyone who replies:
How did u get to where u are now? (be it app dev, device help, other software dev)
Again thx for the help! P.S. what software do u use to program? And which os is preferred, linux, windows, mac?
I'm learning linux as fast as I can and wouldn't mind help there either if its out there.
Sent from my Xoom. Via whatever the heck I want!

I started with knowledge in C++,C,SystemC and some script languages from university + plus some knowledge about programming in general.
We had to use java in the university but i never properly learned it (just couldnt be bothered). I knew the ideas behind it and some concepts.
I actually only started learning java after i had written the exams (one which was about java but thank god didn't require actual working code in the exam ).
This was winter 2010.
So after i no longer had to learn it, i wanted to learn it and started out pretty basic.
Used google alot tried the basic tutorials, i.e. button doing something and so on.
After that got boring i was looking for an app with an actual purpose.
I made a voice recording app, did some bounty requests, wrote a control app for a modification from another xda member and some other stuff, cba to list it all now .
I use the android sdk + eclipse. Currently on windows 7, but that doesn't really matter. I've got a laptop with linux and a virtual machine with it too. It just that i also play video games for which windows is somewhat required and so i'm programming on it too. But it doesn't really matter. Eclipse and android sdk don't really differ on the OSs.
For compiling kernels, you might need linux, but maybe its possible under windows too... (cygwin)... don't really know ;-)
The thing is, you don't need to read 5 books, have 2 degrees in X to start.
Let's take custom ROMs.
No one actually builds those things from scratch.
90% of them are just other ROMs(custom or stock) that have been modified to some extend.
Download a ROM, unpack it, swap some files, change some scripts/configs, maybe recolor some things, add some extra apps, maybe a different kernel.
Repack it and XING you made a custom ROM.. now just flash it and see if it works, if it doesn't... well try again
Trial&Error...
You will get more knowledge about what you can change and what can be done with the time.
There is a custom ROM tutorial thread somewhere on xda, just search for it.
I'm going to write a little bit on my next app now

i want to become an ANDROID DEV!! help me please

hello everyone. my goal is to become an android rom/ app developer. right now im currently attending college for my bachelors in Computer Science. right now im still working on my AA so its going to be a while before i even get into the field. ive researched online about linux and learned the basic codes in terminal to move files, delete them etc. but of course i dont think these codes apply to android.
im not trying to learn all this by myself but i atleast want a basic idea of the type of things im going to be learning.
so far ive downloaded android sdk and eclipse on my ubuntu linux netbook.
do you guys know of any websites that can help me get started or at least point me in the right direction in getting started on my first android rom or app.
thanks
Start with building your first hello in eclipse.
The best place to start is right on the Android site. Watch all the videos and get ready to read lots.
They have tutorials and step by step instructions for your first hello app.
BTW they tell you to break it so you have to fix it.
My biggest obstacle is just doing it.
http://android.voxisland.com has a good set of down and dirty introduction videos to app development for Android. Also, developer.android.com. A lot of that knowledge is pretty essential when doing any other kind of Android devving.
pick up some basic java and you'll have a nice head start.
If your looking for examples you can find them here
[can't post links]
developer.android.com/guide/samples/index.html
I wouldn't pay for videos from some jackasses website - plenty of free java tutorials out there to get you started.
www.anddev.org is a good site
You will need to learn the basic codes in terminal to move files, delete them, etc.
These codes apply to Android.
thanks guys for the replys. im going to start looking for tutorials for java using eclipse.
the android.dev.com pages and anddev.org show me how to make apk files. what im trying to find out is how to make roms and mess with kernels and such. how would the java and apk's tie into that?
I've got the same doubt as ripmeck. I didn't know where to ask for help, so I came here.
And I looked into all the replies, thanks for the help guys.
Unlike ripmeck, its already been two years since I've finished my bachelors.
I'm pretty okay with C programming that includes pointers, structures, etc., (but only the basics of all concepts, cause i know how deep and confusing the root goes).
And I'm slightly familiar with Eclipse, as I have done simple (very simple) java programs in it. Programs that makes use of exception handlers, multithreading etc.,
But I'm not so strong in Java (cause it has got lot more features than C and I couldn't remember it all and make use of it, I've got used to the linear style of coding without making use of any classes ).
My question is:
Should I have to get myself very strong in java before started coding for android app or can I eventually learn the java language in parallel with android development?
There was a thread posted by Cyanogen on XDA called 'some advice' with lots of good info on what you need to get started. Sorry I don't have a link since I'm mobile right now. My suggestion is to find that thread and start there.
Here are some steps vaguely describing what you need. Each is a never ending process.
1. Understand Linux/Unix
2. Understand Android
3. Make something.
My advice is to learn everything you can. Read around XDA and tackle learning each bit individually.
Learn ADB, make some themes or mods using metamorph, learn how to sign files and build update.zip files. Most importantly, have fun.

How to make an app?

I'm putting my theming project aside for now and get onto creating an app that I've always wanted to create that I do not see ANYWHERE in the market, forums, android websites, etc.
I've been reading and reading and reading different threads, instructions, etc. But no clue where to start. I've been reading on App Inventor but realized that it is very limited and I have my high doubts that App Inventor will not be able to achieve what I have in mind to make.
I've got the latest SDK and AVD Manager, JDK, Java, and have been using my emulator to test edited APKs. I'm pretty sure I'll be using my emulator to see how my app progress is coming along and see possible FCs and other issues and correct them as well as adding more to the app to make it even better.
But right now I'm stuck at where to begin here. Right when I was about to create this thread, I was making the name of the Title of this thread and was given threads relating to my title name and saw one thread that was sort of mentioning what I'm asking here.
I read the link provided in that thread ( http://developer.android.com/guide/topics/fundamentals.html ) and got some clues but just not enough to get me started here. I just need that push to get me going and eventually push it out to the market and make some money as a side project and learn from that and possibly make more useful apps. I cannot disclose my ideas here because then someone else (who has experience making apps) could take those ideas from me and go make it.
Is anyone willing to work with me here to get me started? I've helped countless people so it would be nice for a change for someone to help me out here.
There are so much Android development books on the market that I suggest to start with one of them. It's the best way to get some knowledge of the design principles used by the Android development framework.
Another method is to start with some examples found on the web. Just search for Android examples or something like that and you get tons of links
Another method is just to create something, get stuck and try to search for a solution (the most pragmatic method )
Yeah I know. That's why I'm constantly researching. I'm seeing some similarities between Java coding and building scripts in IRC (which I used to do, nothing big, just really small stuff). But my main problem is knowing what exactly are the main tools I need. I've had Eclipse for awhile but never used it. It has a lot of stuff in it and I get lost after a couple executions.
I'm just anxious to get started somewhere and get the momentum rolling for starters.
Could someone point me to a good book/ebook ? There are many out there but I'm sure that are some better than others...
If any french-speaker knows one in Voltaire's language, I'm in too. But English is fine...

Yeah, a good book (english) would be great. Can anyone recommend one?
You don't have to buy books but they do contain a lot more info in one book and would be better to have than trying to scour the internet and pull a bunch of infos together and try to put it together to understand step by step on how to get started and everything else.
Here's a link to a lot of android development books:
http://www.amazon.com/s/ref=nb_sb_s...pment&sprefix=android+application+development
Here's a link to some more info to getting started that is also useful:
http://developer.android.com/guide/basics/what-is-android.html
You may also need to get a Java coding book to help you put codes together properly and understand what each coding does, and tweaking them to work better.
Here's the link to Java coding for Android stuff for beginners:
http://www.amazon.com/s/ref=nb_sb_s...x=java+for+dummies&rh=n:283155,k:android+java
I just bought 2 books for Android application development and looking around for a good Java coding for beginners.

I think any java book will do, as long as it covers the principles of object oriented design and the data structures used by Java. You don't need any info about GUI programming in Java because that's all covered by the Android application framework.
The best Java books are the ones written by James Gosling et al, the designers of Java. But that may also be over the top for Android application development. Just some basic Java will do to get you started. The algorithms needed for basic apps aren't that complex.
App Inventor is a great tool to develop your android app. It simplifies the development and the editor is very intuitive.

How did you learn to code?

Yes I am asking you!
Your personal experience on how you learned coding!
Feel free to vent, my eyes are wide open
my reason? Why I have a book on coding (for Andriod) and the coding package (Eclipse, Andriod SDK, and SO ON)
but is this enough?
How did you start? What was your motivation?
is it fun!?
Please if anyone replies to it, i'd be very happy
Many moons ago, there was a magazine called BBC Micro User, and in it there were pages and pages of code for games written in BASIC.
Normally the code was wrong in places, which meant you had to debug and therefore learn how it worked rather than just copying it verbatum.
This is of course related to our phones as the BBC B was an ancestor to them (now there's a thought!)
Problems? No problems! You need a small program to make your life easier? Go and read in all forums! Ask questions! Start programing by leaning by doing.

Why did you buy a book to find out about technology?!? That book will be outdated tomorrow...I suggest looking up info on the internet and there's this cool thing that's called google that lets you ask any question you want...check it out.
Hope this helped Mizu Luna!
Thank you all for relpying !
think the book is already out dated XD
It was made when android 2.2 just came out....I figured any info toget me startd would be nice.....
I still haven't gotten into the gist of the forum though.....I still don't know many of the terms and aren't familiar to a lot of things talked about...or where things are placed.....and no formal training to help me.....
I guess I'll read on a bit until I can properly place my feet
I couldn't even tell you how I started, I was like 8 years old and just playing around for the hell of it. Been switching around and trying languages ever since. As for motivation, the only reason I ever write a program is because I need something done... I'll feel like I wish my PC/phone/website did something differently - so I make it do that
Really, the best thing to do is just dive right into it. If you want to start with Android, find a good tutorial that at least has you get an IDE and build environment set up... Then from there just start experimenting with some example code, or apps others have written as you go through more tutorials.
If you want to properly learn how to code though, most would suggest starting with something on a PC rather than diving right into Android dev. Starting with an easy-to-use scripting language or interpreter (like Python) is a good way to start playing around - and then you can move on to other languages such as Java with a solid understanding of how programming languages work.
It's all personal preference though, just find a solid tutorial and stick with it. Try to experiment as you go along, try things with the code, and actually understand what it's telling you.
I started with webpage design and slowly moved into other venues. I became interested in making apps for ideas that I had and started to search google on how to code specific tasks that I wanted in my apps and then mixing it all together and making small changes in the code and watching to see what it did.

[Q] Learning coding

I'm looking to learn how to code, mainly because its something that has always interested me but I have never done. I have no experience in it at all. I'm looking for a book that can set me up with the very basics in java (or is it better to start off with a different language?) and hopefully I can move on from there.
If anyone knows of any good books that could help me I would greatly appreciate a link to it.
Thankyou.

So even on sophisticated websites like this there are still childish idiots like yourself on them. Yes you're probably right in that I should have searched before creating a new thread, however obviously I didn't think of that.
Maybe next time you should try and show maybe at least an inch of maturity when posting. Oh and for someone who would like me to donate to them and buy/download their apps you're not going the right way about it.
I dont know if that because you joined before me or have more posts than I do, this makes you think you have some superiority over me or new members, but it doesn't and remember with every new member is potentially another donation to you for your work. So if you want to carry on alienating these member towards you then carry on but if you don't then you might want to re-think your mentality towards them, because personally I wont be donating or ever downloading any of you apps.
With that said, thankyou for the links.

I don't want anything from you.
You want something from this forum, more exactly from its members.
You want an answer.
You did not pay anything for the knowledge available for free here, neither the time a member puts up to help you out.
What you could do is show some courtesy by using the search function to not waste the time of people who are willing to help out.

Both my join date and post count are indirectly related to this.
It just means that i have seen too many threads like this, which could have been avoid by a few seconds of search.
What is more astonishing is that i still browse the question and answer forums to help people out.
Yeah maybe some people won't get the answer they wanted to hear, but hey you got your answer.
Im confused now, from looking around it looks like python is the most basic of languages but if i was to start with a dummy book for that, would it actually help me achieve learning java? I dont want to get the wrong book and be completely lost because I havent learnt the complete basics.
It seems like everyone says different things and I cant get a clear answer of where to start.
@Dark3n I'm not going to sit here and argue, you have your view I have mine let's leave it at that. If you would like to help me (which somehow i doubt) that would be great, thanks.

The most basic language would be machinecode (ASSEMBLER).
But beleive me that it is really painfull to write and learn.
Python is a nice language to write in, no doubt.
But you should think about what you want to do with your programming skills?
Something Android related?
Then you should look at C for linux kernels and the lower levels of android.
or
Java for Apps and the higher levels of the android os.
If you want to learn java there is no advantage in learning python first, besides that you can program in python and java.
I would like eventually to create an app for android, which is obviously done in java but if i got even the most basic of java books would i still be lost?
Edit: I just remembered there was a thread similar to this one where i already had a lengthy discussion about this topic.

Not totally lost, you will learn about variables, if statements, loops, classes etc. those things are all still valid when writing apps. Those somewhat remain valid through most of the programming languages.
But basic java does not cover connecting your java code with the android user interface or making use of any android feature (rotate display, sensors, telefon,gps,etc.).
But seriously you don't need a book. Of course you can get one if you really want to. I would probably search the amazon bestseller list for something on android programming (for dummies) which does not require previous programming knowledge.
You can also just jump into it, google for "android hello world tutorial" or something like that.
But the official hello world tutorial should do.
Should make you able to write your very first app pretty quick. It's only a "Hello World" app, but hey thats where everyone starts out.
Aside from the programming itself, knowledge of Linux and *nix orientated operating systems would be useful. Terminal commands and such will prove invaluable if you take application development to a professional level in the future.
C and Java are obviously what's mainly involved in Android. But if you want something simple to begin with look at HTML and CSS (which are basically just translation matrixs not languages).

HTML and CSS knowledge would help a bit with the android user interface, but not with the actual code of the apps/programs themself.
I would advise the OP not to start with HTML and CSS if he wants to get into the programming buissness.
Unless you are going to make webpages HTML and CSS takes you pretty far of the track.

HTML and CSS, are two useful skills to have regardless. As you mention for interfacing, and also for the ability to work with Web Apps in the future. For myself learning Javascript and PHP has certainly helped with getting into Java/C.
Certainly HTML/CSS aren't related to learning Java and C but it's a good entrance point to coding in general. Although you yourself may see it as sidetracking, it can help some not to jump in at the deep end.
I wish the OP the best of luck.
Hey dar3n, I had posted a similar thread as well, minus all the attitude, but I agree it does get posted alot, after talking to u and searching around a bit. Why dont u get someone to make a sticky post in one of the newbie rooms, or the q&a. Start a sticky discussion and I bet half these posts dissapear.lol

Starting to develop

Hello, xdaDevelopers (Is it like that? Or XDADevelopers, or XdaDevelopers, well, doesn't matter, you can leave your opinion about that here, too.)!
I can see this is kinda a common thing around here, but, I really need the basics for programming, with a final goal of being able to make code for Android (from APKs to ROMs and such).
I just need people to point out good sources of learning, with a learning curve, please, that would be a great bonus in understanding what the heck I'm learning, from the basic of basic, to the goal here intended.
Maybe this is a bit too ambitious, but I pretend to be a professional programmer in the future, but I still have a kinda long way to college (3 years), and I wish I could start sooner that, it could even make my college life even simpler.
Well, I hope you leave your enlightenment in this thread. Thank you very much for any opinion given here.
*bump* Sorry. It was already in the second page. I just didn't want it to fall into oblivion.
Well your going to have to stsrt learnibg java if you want to make apps. Read some books. Also take a look at thenewboston channel on youtube.
Im learning myself. You just need to start and don't give up

I'm also posting (lazy way of subscribing to this post). I knew java, although it was long ago. I'd need a refresh on everything. And then, knowing java is not the only thing you need, as you also need to know how to develop for android itself. Up to date, which book would you guys consider the most easy to follow to learn easily to program?
Thank you!
Yes. I'm asking for links or books (preferably e-books) that could have all that information. I just hope I can become a great XDA developer.

+1 to this. i would also like to get into learning how to develop for android.
google has a lot of info on their developers page, it's probably one of the better places to start.
i don't know many other good websites or books though. anyone have suggestions?
If you want to develop Application on Android. You will need...
1.JDK (Java Development Kit), which includes the JRE. ( I use Java SE 7 )
2.Eclipse with the Android Development ( I use Eclipse Classic 3.7.1 )
3.Android Development tools ADT Plugin for Eclipse
( I use android-sdk_r13-windows.zip )
more detail http://androidcontrol.blogspot.com/2011/10/android-development.html
java for the user interface "pretty" part of the apps, but the real heavy-lifting guts of the app (where the real magic happens) will normally be written in c
