So I've been palying around with the Android SDK. I've done a bit of developing before, but never in Java. The Android APIs are pretty well documented, but I'm missing the basics of Java programming (data types, declaring variables and constants, file operations, etc.).
Does anyone have any suggested references? I've been digging some myself but it's slow going.
If you haven't already, check out http://www.helloandroid.com , http://www.anddev.org , and look for O'Reilly books on Java or skip the first five chapters of "Java for Dummies."
Both of those are really focused on Android specifically. Anddev.org is really for developers while HelloAndroid.com is more of a blog and not much technical info.
Here's the best site I was able to find about the Java basics.
http://en.wikibooks.org/wiki/Java_Programming/Overview
After that it just learning the APIs, and I think Anddev is really going to be the site to watch on that.
I thought I'd share in case there are other aspirng developers watching.
Developing Thread
I didn't know where to add this, but if you need to move it to the right thread please do.
I want to start developing, but I don't know any Java. I'm sure that you guys probably know some books that I can pick up to start learning. Actually any advice or resources would be great since.
Ever since i got the G1 and seeing everybody speaking code it realy started to interest me. So any help would be greatly appreciated.
Thank you
I heard the dummy books aren't that good to start off with, but thanks I'll still look at it.
Bump,
Come on people i know you have some ideas, so i can learn java or anything to develop for Android.
Im also thinkin about starting or trying to develop for Android, like how would I start off makin a custom rom build?
Come on guys

that would have worked great if you spelled develop right LOL
The thing with programming textbooks is no one can ever agree on what book is "best". Some people like books that are basically just giant lists of functions and their syntaxes, some people like books with a lot of examples, some people like books that primarily explain the most basic functions in plain English. Some folks don't like to use books at all and learn programming purely from studying others' source code.
A lot of the Java-specific books written in the past decade are written without requiring pre-existing knowledge of C++, which would be good if you have never programmed in any language before. I think the "Headfirst Java" volume is supposed to be well-regarded, but I can't say that from personal experience.
Of course, you could always just find your local community college/adult school/vocational center and sign up for Java classes. Some community colleges might place Java far down in the CS track and make you take prerequisite courses. Depending on how the course is set up, what text it uses, and how much ground it intends to cover, it may or may not have prerequisites.
Good luck

Learning to Develope on Android
I want to learn how to develop apks, use the SDK to its fall extent. I put Debian on my phone and windows x , made a couple of my own themes. However, i want to do more i just don't how the knowledge to do so. i tried to read on how to use java, c++, c.net, etc but I'm just not picking it up all to well. I just installed Ubuntu on my computer but my knowledge of Linux is very little. I'm welling to put the time and effort into learning how do these thing but I'm getting no where. Watching people like JK come out with roms just makes me want to do the same. i also just updated to the new SDK but for some reason it won't work (haven't gone around to find out why thou). Can anyone help me out, maybe point to toward some good sources, books, or whatever. i love messing with me G1 i just want to take it to the next level. i finish school on the 20th of this month and i have till July 15th of free time ( i leave for Basic Training). so i would like to get started between these times.
If a similar thread was already made i'm very sorry i searched like crazy to find one but had no luck, so please don't get made if there is one just point me to it.
THANK YOU

I have read so much my head could explode, but i think I'm reading from the wrong sources or just not getting it at all. I'm reading some books i got from friends with Master Degrees in this stuff and they are just confusing me.
The major problem is I'm a fantastic hands on learner but i have no one with the spare time to help on any of these. I've been taking the Cisco Academy Online and didn't get any of it until i had someone help with a hands on learning and it all just flowed right into me easily now i'm close to getting my CCNA.
But i'll keep reading till i get it, some day
fankly i would say if you wanna make apps then read a buch of tutorials, stare ata lot a source code. and create a few simple things first. i have not bothered with any of the sample's with the SDK because i just don't like them. i do however read lots of code daily and am currently trying to find the best way to get my app running. i am one of those people that if handeed source code i could tell you what it does and when, but if told to write a program that does something it will take ages for me to figure out. even with a year of both java and VB .net under the belt i still don't know much since those classes where a long time ago. read lots of code and you could probably benefit from having a java book around too
I found the sample code and tutorials shipped with the SDK very educational, and would recommend the soon-to-be Android developer to plow thru them. They give you (at least they gave me!) a basic understanding of how Android apps are supposed to work.
If you're not used to general Java development at all, I recommend starting out with a beginners book on Java development first.

@hellsonlyangel - I have the same desire to learn how application development as you, particularly Android development. I've done the same as you over the years, reading tons of books and online tutorials on programming, but learning very little. I am taking a very general, but comprehensive, scripting course right now as a part of my Network Admin degree program, and I fell that I understand more after 2 weeks in this course than I did from all of my self study attempts. Sometimes, there's just no substitute to structured learning programs. The ISBN for the book that my course is using is 1418836338. It can be had on the cheap, used for around $8, just in case you want to check it out. Good luck.

So the best way I found to learn this is through trial and error. I will write code for a simple program, for instance a clock app. I will work on it until it does what I want it to then I will trash the code and build it again using what I just learned. It's just a lot of practice and don't get too deep until you have a full grasp of the concepts behind programming. You'll just get stuck and frustrated.
It's not just another one of those 'LOLZ WANA DEVLOP PLZZ HELPPPZZ'.....
I'm very serious and need to know where to start off. I would maybe do it for a living when I'm older. It's something I've been wanting to do for a while. I used to mess around with some private servers coded in Java, but I didn't learn much.
I'm just wondering if there was a place where I could take classes online, or a good way to start off. I would be using my Evo for development aswell.
Any serious help would be appreciated.

The best place to learn and this may be a shock...for real. But i had begun to read an android development book and that didnt really do it for me but when i started to read Google Development pages it all made sense.
developer.android.com
Check it out.
1) read the entire dev guide
developer.android.com/guide/basics/what-is-android.html
2) install sdk and eclipse
3) build hello world and deploy to emulator, then to real device
You'll be on your way to devdom if you can make it through these 3 trivial steps
I bought three android books and they all seem to be very helpful in their own ways.
Hello, Android! 3rd edition - Great for beginners to the android platform
Professional Android 2 - Great and has a good amount of corners covered. From layouts to bluetooth and wifi. This one is by wrox and the code samples are available online without purchase verification.
Advanced Android - Good but not really worth is.
I've spend sometimes using eclipse but i can say it's quite buggy for now.
You may wanna stick to it but i suggest to test the last IntelliJ X Community
It's free and it get Android dev without plugins. I get this tips from the Twitter
of Romain Guy ...
For the dev, a little book from manning.com. They offers code is you register
you can get 50% of the price. Android in action.
Then for the advanved topics StackOverflow is now replacing the android
newbies developpers google group officially and there's a lot of advanced topics.
Give yourself some weeks to get some results, you've to learn the philosophy
of a new system.
Hey guys, so I've had an interest in programming for quite a while now. I have tried Python, but I didn't have much success there. I really want to learn to program, and thought I'd start on Android, because I have a few android devices. I know practically nothing about Java(or any other programming language). I'm not really someone that can learn from examples, so I'm looking for some good guides. Guides that start from the absolute basics and work up from there. What are some good ones?
TL;DR? : What are some good guides for learning Java for android development, for someone with practically no programming experience?
Thanks!
http://ocw.mit.edu/courses/electric...nce-and-programming-fall-2008/video-lectures/
This is mostly python. But once you learn one programming language then all the others will fall into place, the hardest part is learning the first one.
Hello,
I would like to get into Android game development, mainly as a hobby, but given how obsessed I can get about hobbies I will not rule anything out! I have limited programming background (a bit of C, VBA, JavaScript...just the basics: variables, If/Else, For/While Loops, Arrays, functions, sub-routines etc..) but I tend to pick these things up fairly quickly....however I expect this to be a real long term project for me.
I have attempted to determine a sensible starting location and direction for a beginner to get started, but with so much information it really is a little overwhelming and I can't figure out what would be the most productive way to spend my time right now.
I gather that Android development requires Java knowledge, right? If yes, can anyone recommend any good websites/books with tutorials and code samples that can be used by someone who doesn't have an coding background already? To what sort level should I try to attain in Java before it's worth considering the Android specific side of development (I'm aware 'level' might be very hard to define!), or should I be thinking about these things in tandem from fairly early on?
If anyone has gone through a similar process, can you share your experiences? Pitfalls to avoid? Things not to overlook?
I have a couple of hours a night to dedicate to this for the foreseeable future, so any help filling that time efficiently would be much appreciated!
p.s. If there is a forum that is more suited to my question that I'm not aware of then please let me know!
Thanks!

I once wanted to become a droid developer too bro! I didn't get far though as I needed to focus on my day job more.
Anyway, what I did was learn about SDKs first. Just google it up, there are actually a lot of tutorials on the web. You'll need to be prepared to spend some money though for the SDKs.
you might get an idea here

Thanks for the advice, I noticed that google has it's own SDK, is it still worth investing in one of the other options?

Thanks for that. I've watched the first three so far, and have Eclipse & the SDK manager set up now. It was interesting to see that Android code is actually compiled twice, and given that the second stage doesn't have to be Java, it means that you can write the apps/games in something else, e.g. C.
Do you have any advice regarding which language would be the most sensible to code with? Apparently C is much faster for some things, so maybe it would make sense to dedicate myself to learning that rather than Java?
I don't know which would be best. All I can say is that I am learning java at the moment and hope to move on to android soon!!
Interesting to note Oracle are in court with Google at the moment in regards to copyright infringement. Android really is not a programming language , it's a mix of other languages....
I recommend this book...
http://goo.gl/APX0w
You can obviously get it at other places, and cheaper than that too, but it's a great book. It covers setting up Eclipse and the Android SDK and gets you going with lots of the major elements of both Java and Android together.
I rate it, but I rate Sams books in general. They've always been good.
Yes, I've already searched the forums. I know there is a guide on here from a developer, but that doesn't leave as much open-endedness as I would like. I'm looking to learn to develop games and applications for the Android OS. I've spent the past week learning Java so that I could learn to develop for Android, but it seems to me that is only the tip of the ice berg. The question I have for you guys is how do I go about learning this stuff? I'm sure most of it is trial and error, but hell what can I try if I don't know where to start?
I know you guys probably get this type of question all the time, but I'm not wanting to take the easy "can you basically code it for me route?". I really want to make the game I have in mind and it's fleshed itself a bit more since I actually learned the backbone of the stuff as well. I've seen The New Boston stuff, but that guy doesn't seem to know what he's talking about. He calls > the less than sign and vice versa. :\

if you are e developer , to learn java (at least the basics) is the step no 1 , and its not so hard
if you have no idea what programming means , then you sould spend time to have some general knowledge about programming.
then you sould try to understand android platform , read general info , read sdk documentation , read about the structure of an android app , and
play a litle with Eclipse. you can find everything on the net. tutorials , code , how to etc.
Start doing tutorials, that's what I'm doing.
Check YouTube for beginning Android programming and stuff like that. Eclipse has some good tutorials as well

I think you are referring to my guide. You say it "doesn't leave as much open-endedness as [you] would like." What do you mean by that?
The guide is first and foremost written for beginners.. if you have suggestions on how I can improve it, let me know
And I wouldn't call learning "trial and error." It's more of practice and understanding.
You are right in saying "What could I possibly try if you don't know where to start?"
Following a structured series of tutorials at first will start you off on a strong foot.
