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] i want to make a rom?

ok guys imma try and make a rom for g2x with sense3.0, so i need alittle help, where do i start? and its there a thread i can read on that will help me alittle?

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!!!!

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

[Q] How to build an Android App ?

Is it possible to build my own android app (even if I am a noob with no real knowledge of programming)?
I know of "App Inventor for Android", but it barely has any options from what I see
):
I basically want to build an Alarm Clock for myself
(and maybe other will like it too)
THANKS

To make an Android app, you should learn java. Then look at the documentation for developers on the official Android website. If you do not know how to code, then you will end up with some premade app, that gives you little customization as to what it is. I do not know how to code but when I have the time, I will learn.

Where does one learn how to code? Is that something people learn in Computer Scenic degrees?
just wondering...

Use this video to learn.! Its much easier and from a reputable source.! Its an hour long though. They explain very well, I thing they also have a rom development vid also.! Subscribe to them.

Thank you!!! the Link is broken though

The code is written in java. Learning java (plenty of books and websites out there to learn the basics) is step one. Downloading the android SDK and Eclipse or Netbeans IDE is step two. That's it. Once you learn the basics of java you'll know what to do with the sdk and the ide, both have detailed instructions in the programs help section to help, as the "hello world" script is their beginners walkthrough example. Also, there are some good video tutorials on you tube that walk you through the entire process from getting the SDK to posting your app on the android market. As is the case with most questions, google is your friend, and you tube is his brother.

[Q] ROM Development.

I am interested in becoming a ROM Developer for Infuse 4G. I have little(very little) coding experience, But tend to learn fast and grasp concepts easily. Since I'm completely new to all this, I was wondering if anyone could point me in the direction of a "How to get started" type of guide with all the necessary development tools I will need. If you could help out I'd be grateful, and I hope to soon contribute to the XDA community. Thank you.

I too am interested as far as i know you need to know java, be familiar with linux and i think C++...but id like to know for sure what is needed
My brother is learning java in college and offered his java book to help me learn-as soon as i get that im gonna begin teaching my self java with a few tips here and there from him but mostly teach myself because thats the way i learn best
Sent from my SAMSUNG-SGH-I997 using XDA App

Im up for it too...
i di some porting fot the Captivate and im sure i can take on the Infuse

I'm so pumped to start work on a custom ROM, I love my Infuse 4G would be so much sweeter to learn even more about it too, And to actually see what these guys go through to bring us the latest ROMs and stuff.

You guys really want to learn? You have no idea .... but I will help if I have time...

Ohhh...i can only imagine how hard it is to learn, and then to actually put out a rom after that. Trust me i dont plan on building one anytime soon, this is gonna be more of a slow on going learning process for me...im only 17 so i got time
But your how to thread should help a little bit at least with getting an idea of what the system files look like and the time it takes to edit them.
Dman do you think you can just let me know what i will need to know to make a rom that way i can tackle one thing at a time at my own pace
I know for sure i need to know java, but im only assuming i need to know the following: linux, adb, c++ is that all or am i missing anything?
Other than listing what i need to know, you dont need to help me because i doubt id have the time to keep up with your teachings

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).
Once again http://thenewboston.org/index.php

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

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.
