Dev help

Hey all, I wanted to start Android app development as a hobby. I am very comfortable with C++, but I know that Java is necessary for Android. What parts of it will be important, and could you please recommend a good tutorial? Thanks.

I have been trying to get into making live wallpapers myself. I have been asking everywhere about what I need to learn to make a live wallpaper. I have no idea where to start or what to learn. I have posted several threads and ask devs in the market to & no one wants to tell you anything about where to start or what to use. I really don't understand why no one wants to help, especially here on a Developers website. Hopefully we can get a Senior member to give us some good tips.

[Q] New Young App Developer Needing Help

Hello XDA, [I Posted this in Android Development...no response]
I have just finished my first year of high school, and have spent 2 years around Windows Mobile and Android.
I want to start developing in different parts of Android, Applications being the top priority.
I have found and got many guides such as Sam's Teach Yourself for helping me build applications.
I know I can't start off building advanced apps. But the place I need help is where should I start, and what things I should learn such as Java, Adobe Air being a few.
If you guys can please maybe make a list I should follow or something...This would be greatly appreciated,
PLEASE GIVE ME AS MUCH ADVICE AS YOU CAN THANK YOU
Thanks A lot

I would start with Linux, since that is the basis for all android apps.

Thanks a lot for your reply....I will look into that

Sent from my LG-P999 using XDA App

sounds like he wants to try and learn how to develop rom's, with no experience in development. but he's wanting to build a rom for the g2x that incorporates sense3.0? that's what i interpreted.
So someone needs to go to the book store,library, or Google and start reading on Linux, java (more app based from what i read), and other books on code that's used in mobile development
correct me if I'm wrong anywhere in this response.

That's exactly what I am talking about... How many times have you written something like that after someone responds to your posts? I get that you want to do a sense rom for the g2x... It also seems like you want to use others work(and give them credit, of course). Hop on to amazon or head to your local bookstore, there are whole sections about android development...

Expert developers are EXTREMELY challenged to port over platforms from other brands. To think that your going to do it with no experience is never gonna happen. Start easy, download CM source code, try to modify things, and maybe in a few months you can put something out for us. If making a rom was that easy, we would all do it.

Were do I start!!!!
Sent from my LG-P999 using XDA App

get a book and read.
start with learning JAVA (this is if you have no programming experience)
once your familiar with JAVA and feel comfortable reading JAVA code and writting in JAVA.
then go get a book on ANDROID Development. I found a great book to learn about android development called " Hello Android", by the first 15 pages i had already made a somewhat complete Sudoku app, not out of interest but as this was the lesson in the book i was on.
No one can help you until you want to help your self, not trying to be a dbag but sounds like your wanting someone to walk you through step by step and through previous experience trying to verbally or explain to someone through text on to do something as complex as coding with them having little or no knowledge on the fundamentals and basics is/will be very difficult and frustrating for you and the person trying to guide you.
ps... might not hurt if you learn how to read/write/understand linux as android is based ontop of linux from my understanding

Well it would be better if you could give more specific info about what error you get where exactly you are getting stuck while installing it.
Here's a link to a tutorial to set up eclipse.
www.vogella.com/articles/Eclipse/article.html
This is probably the wrong forum for this kind of a question. Not to mention that threads here just get lost really quick. You might want to try the Q&A forum next time.
I am guessing you might not be knowing much about programming either. So instead of trying to make a game at this point focus on learning to program. Search for Java tutorials on youtube and google

The errors gone and i have my first app. So plz help with a game app.

Here is a simple open source game - https://code.google.com/p/newtonscradle/

Really, your approach is just wrong.
Nobody can help you if you don't know any basic of java programming (at least).
First of all you have to read java and android documentation, then open some tutorials in eclipse and play with them, then start with simple apps and progressively make it more difficult. At the end you'll be ready for a great game.
There's no short way unless you want cut and copy stuff and don't care about learning something.

Theres more to a simple game than to a simple app. Start by buying a book on Java if you really want to get serious about it.
If you just open up that open source project linked above or maybe any example game in the SDK you'll see how complex a simple game can really be for someone who is new to programming.

Make a text based Mafia game, I don't think there are any of those yet.

I don't want to upset you but if you jump straight to the android without a basic knowledge of object oriented programming the learning curve can be quite steep.
As said above, the best thing to do would be to get your hands dirty with basic java coding first.
I read this before jumping to the Android world: Introduction to Java Programming by Daniel Liang A much recommended and well-written reading.

I know java basics

Development for Android is done mostly in Java. It is very simple programming language, after a few weeks of practice you should be good at it. Here you have a tutorial on how to create first Application: http://developer.android.com/training/basics/firstapp/index.html

The New Boston
The new boston has a 200 video series on android application development. It's a little bit dated but if you go to http://thenewboston.org/index.php. It shows you specifically how to develop for android 2.2 (froyo). that being said most (if not all) of those applications should fun just fine on any OS 2.2 and above.
The main things is that you are using the API level from 2.2 so unless you change it later on you won't be able to use newer features. BUT... it can take someone from 'eeerrr I think this be mah keyburd' to 'Yeah, i just wrote and android app and put it on the market. BYAAAH!!!'.
Definitely worth checking out. I checked it out and when they came out they were cuttign edge pretty much (like a year ago lol).

HA... I just realized that you said ROMS. well that is a completely different story... that is really trial and error until you figure out how everything works.
If you aren't running on ubuntu then download virtual box:
https://www.virtualbox.org/wiki/Downloads
Once you have that the EASIEST way to get started is to download the ISO for ubuntu 10.04:
http://releases.ubuntu.com/lucid/
Once you have created the Virtual machine with ubuntu 10.04(simply because it is the best for development):
http://www.youtube.com/watch?v=jC6jSiGSbUE
Then I recommend to get your environment setup you follow the instruction at the below site:
http://www.freeyourandroid.com/guide/compile-ics
Now that I actually read what you were askign for and am not a complete tard... hope this helps.

I looked it up and it also gave me a link on how to set up Ubuntu. So my next question is, where do you get source codes? I myself have a vibrant so of course it doesn't get source code updates although I know that some ports are from the gnex

Is it fairly easy to pick up then? I program in a language called SAS and I have done bits of Java and VB in the past.

Sent from my SGH-T959 using xda app-developers app

sounds like xda veterans should compile an Android rom "how to for dumb dumbs" e book and put it for sale in the play store and on Amazon self publishing. you'd probably make a fair amount for yourselves and the site, depending on how you went about it; problem is I think all forums on this site would then be totally flooded with repeats, duplicate functions mods, crap roms, and just generally bring the average level of code down to hella-sloppy levels. yikes, pick your poison

I understand that serving requires a lot of time butnim serious about this. Not o my that my friend has an lg lucid and I have other people who would like development for that pho e which I would help with hopefully

roms are also largely in java (or davlik, anyway)
You can start by compiling something like CM10 (not an easy task, I might add).
Most devs begin because there's something they are itching to have but that doesn't exist. Once you've successfully compiled, you can start tweaking these things in.

is there no how-to guide somewhere for your-first-compiling and what-files-do post for dummies somewhere?
