Database Develop

I Want To learn

I want to learn how to develop...I mean of course it wont be an over the night thing, but i still have 70 years to spare.
I want to contribute to the community, and isn't that what linux is all about?
My first question, Can i develop android in ubuntu? or does it HAVE to be eclipse?
I wouldn't mind downloading both anyways since i want to learn how to use ubuntu anyways.
yeah..so i guess all im asking is for someone to set me in the right direction?
Also android is written in java too right?

Eclipse is a program that runs under ubuntu/windows/mac. It's only needed for development if you're going to be doing app modifications, etc, it completely depends what kind of development you want to do.
Kernel/Source editing can be done in notepad if you want but you're still gonna need to know some java.

Interested in learning as well
I'm also interested in learning to develop apps for android and apparently we're in the same boat and level (beginner) - Currently I have 22 apps and 10 live wallpapers I'd like to develop but I'm still doing the reading and software acquisitions necessary to start so PLEASE drop me a line on anything you figure out or learn and where you acquired the info/tutorial - who knows maybe we can get this software company going lol (big dreams here)
The guys on here seem to be light years ahead of us but I've got hella time to devote to learning, testing and development so I'm ready to go

JAVA knowledge is a MUST for development.
Also based on my own experience Eclipse does not work well under Windows.
I've tried to modify the Launcher app from Cyanogen's source to have 7 screens in stead of 5 and it failed each time. I edited it in Ubuntu and it worked the first time. Just need to have Java 5 installed (not sure if there was a fix for Java 6 discovered yet). Eclipse works very well in Windows if you just plan on editing .9.png files but that's more theming than development. So bottom line Ubuntu is highly advisable.

I guess you could always start somewhere by reading some of this.

[Q] Software development

To all programmers,
I am a Young fellow interested in getting into software development. However, I don't know where to begin.. There's C++, java, and python all supposedly good languages to learn (c++ being a bit harder). Which one should i choose.. then I need books, sites, any kind of help/suggestions on the chosen language.. Please enlighten me developers! You all do great work for the community and I thank you for your time and input!

if you are looking for Android
you need Android SDK + Jave eclipse those are important to develop for Android
and there is some more softwares here in the XDA
APKTOOL etc
if you wanna edit apk (XML) Hex Editor is your choise
this is what i know

I was thinking of development I am completely new so perhaps that is the best route to go?

yup , 1st you have to know what is AndroidSDK , visit
code.google.com
and you'll get the basics

I started with vb, then c++, python, fortran, cobal, unix, and now java. Java is what Android apps run on. But vb will give you basic skills. c++ will teach you about everything else. My $.02

Thank you all for your posts now for another question! How did you learn? It looks like ill be messing with a little of all of them though it seems I may focus more on Java. Did you learn with a particular website? Prefered books? Thanks again!

School and old programmers. I could not have learned it from reading a book.

I'm a rather persistent guy.. I think I could learn from a book and perhaps ask a few questions on hereshould the need arise. I have a few friends who have some knowledge as well on the subject. I think I can self teach myself I just need to know some of the sources others have used. like java for dummies if that's any good or for that matter a real book..

Head first Java is a good book for beginners.

If you have no prior experience in programming, I would recommend starting with Visual Basic. The Code Project website is an excellent resource.

And if you are going to start with Visual Basic, then the MSDN website will have tutorials, code examples, etc.

guys he is going to develop for android i (Think) , why the heck he needs visual basic for ? android app only can develop by AndroidSDK and ECLIPSE(JAVA)
visual basic its for pc apps though

You start with basic cause it's just that, basic. Teaches you principle concepts. Things that you would already know if doing java. Taking a java class or reading a java book, they think you already know boolean logic. It's just a good base knowledge set to have.

That's right, forgot about that. Tons of free stuff

so what I'm getting is I should develop on pc first visual basic is a good starter. Interesting, Now I have a few sources on all of them except C++ which though I may not mess with it immediately I may take a peek at it anyways. Glad to know I have same people that know what their talking about helping me out! my friends have limited knowledge.

Hello,
I've Created an App for the Galaxy Nexus fans and Users. This app Provides Information about Galaxy Nexus some from the Internet and some are Built-in.
This App is created from http://mobile.conduit.com. It includes Photos, Videos, Reviews, News, Feeds & Multiple Facebook fan pages and they are all about Galaxy Nexus. Please try this. I know that the quality of the app is really poor, But you can give it a shot
WebApp & Demo & Download from your phone:http://googlegalaxynexus.mobapp.at/
BTW I'm known as SIEGE|MASTER
And If you like my work or my App, Please Consider Pressing the Thanks Button
I want to make Simmilar App about Other phones (e.g. Galaxy Note, Galaxy S III, S II, even more) , So try it and if you like it please comment, So I will choose that shall I make another app like this for other phones or not.

If you want to write an app, do the hard work. Tools like Conduit produce ugly apps with limited feature sets. There's no realistic shortcut - interface design and coding are things you have to learn.

I don't have coding knowledge bro, I want to learn coding for Android and Java as it is required for Android but, I heard that Android will be converted to C#, So if I learn now, I'll have to learn C# again..

Well.. no.. android won't be converted (there's only a version using c# instead of java), at least in the next versions
However, creating an app like that is pretty simple, you should try

We all have to start from somewhere. In any case, you need some basic knowledge of multiple languages if you're going to be working cross-platform. There are porting tools available which can help you along the way. Simply put, there are no real future prospects with Conduit and similar tools. You create an app that looks like the million other ones made on Conduit, you might make a quick buck, but that's it.

Programming : what to learn next to be able to port android roms?

I have completed "The C programming Language" book and I want to know (in sequence) what all i have to learn so that i can port android to any phone which dont have android by default. I know that there are few things like device driver programming, micro processor programming but I am totally confused
Please help

Learning about Linux operating systems will help, and UNIX commands too.

Start learning Java

Android used Dalvik VM. So you can start learning Java to start developing apps.

You are talking about porting Android to a phone which doesn't come with Android by default - such as a WP7 or Symbian phone? That is far, far more complex than you can begin to imagine. The people who do this for a living study it at University and then spend years and years doing it for a career - and they each only normally work on one small part of the whole thing.
There is an old phrase "Don't try to run before you know how to walk". I would suggest that you start with looking at creating a ROM for an native Android device from scratch. You would then have the drivers already and you would just have to learn and understand how to build a ROM from the ground up (not simply taking someone else's ROM and customizing it a bit)

Thanx now i understand why I was not able to understand anything lol
really thanx I will certainly get to work i know some one who got galaxy y

Need to learn the android development... From basics....

Hi,
First of all thank you so much for starting a forum for learning the Android Development.
I am very much interested in learning android, and i have gone through the official android developers site, and downloaded the SDK.
But i am stuck there, coz i am very new to the Linux/Unix part. I would like to learn more about that, but i do not want to learn programming unless it's necessary. I know it will take a long long time to learn that. So can anyone help me with the app development or fixing/understanding ROM/Kernels.
Sorry if i am being too much jumpy in the starting itself, It's because i do not know where/how to start.
Thanks,
Les

Unfortunately without learning programming, you will find it difficult to do any app development and kernel understanding or fixing.
Programming is key to both of these. So although you don't want to, have a look at some of the resources out there on how to learn to program.
Apps are written in java, kernel code is mostly C.
Maybe this helps? I think failing to start by learning to program will just leave you disappointed.

If it's okay, I'd like to suggest something.
@lesfauves
For kernel development, you really need to learn C, C+, C++ etc. C is the most important language here. However if you're gonna build vanilla kernels (with no modifications whatsoever), a simple guide should do it. Modifying source code requires knowledge of C (and maybe some other languages) as pulser_g2 has said.
For app development, you need to know the basics of Java. It's a must. Otherwise you'll end up getting nowhere.
For ROMs, you need to have a good understanding of both Java and C (and some other languages).
You can learn these online. I'm learning C myself. It's really easy.
Hope I helped.

I too want to learn android development, just dont know where to start. Been waiting for xda university to open up for this very purpose. now I went through the site and still have a couple questions. I see that learning C is fundamental, where would you guys suggest would be the best place to learn? i was hoping for something like codeacademy, they dont have C though. Also, which distribution of linux would you guys suggest to install?

If you just want to dive in, and have fun creating small Android apps, learning Android concepts as you go, I highly recommend MIT App Inventor (AI): http://appinventor.mit.edu/ . It used to be Google AI but Google wanted to focus on other things.
I have decades of experience in Unix & Linux low level mostly C software development, but was new to Android & Java in Feb. 2011. App Inventor was a great intro to Android concepts, but it seems almost impossible to make commercial quality apps of any size with it.
So after a few months I dove into Java with the Android SDK & the concepts I learned with AI transferred well.
If you want to run Linux on your PC, which is a great way to learn Linux in general, Ubuntu remains quite popular, but a lot of us techy types have moved to Mint. I'm still on Ubuntu but will likely try Mint at some point.
The original and seminal book on C language is this: http://en.wikipedia.org/wiki/The_C_Programming_Language . It was a great intro for me back in the 1980's. But many C++ people will tell you learning C first may mess you up for C++. I never really caught on to C++ and don't care now as Java is IMO better.
This is the seminal book for C++: http://en.wikipedia.org/wiki/The_C++_Programming_Language
In general I think C is better for kernel and low level Android NDK stuff; C is the language of the kernel. For higher level Java of course, using Eclipse as an IDE since it still is the most widely used IDE I think.

Any good sites or tutorials for learning Linux????????????/

A great site that I use to learn with for web design and development is Lynda.com which has a good amount of C tutorials and learning. It isn't free but a subscription is worth the site. There is a huge amount of information, tutorials, and learning that can be done there.

Go look at my post in this forum section.! May help you

Ok lets say i want to learn how to make a device tree for my device cause noone make it...then compile aosp or cm and make it a usable rom for a device...to go to a bookstore to buy a book in my language to remove the possibility of wrong learning...what book to buy??java, c , c++??

This is a great idea, and as i have just started learning C at university (And Java next year woo!) i will be visiting this alot for reference and tutorials. I still find C hard to get grips with but i do have a basic understanding of it. I also like messing around with kernel's and stuff on android and really want to make my own ROM or kernel soon!
So thanks XDA and everyone involved in this !

If you want to learn how to make a device tree check outthis guide, then when your ready to try compiling AOSP and Cyanogenmod check out this guide. If you want to learn to compile ROM's and then I would recommend a book on Linux and C for programming kernels such as C All-in-One Desk Reference. On the other hand if you want to program applications a good Java book is important and I would recommend Head First Java. Hope this clears things up, let me know if you still have questions.
