Eclipse IDK:
For developing Android apps
if you really want to be a developer you must try to learn eclipse
APK manager or APK tool:
it is used to edit android apps
it decompiles android apps so that it's easy for us to edit them
YouTube and Google:
for tutorials to learn how to use them
hope that helps you...!!!!

Thanks for your reply .........
i will try learn that .......... and how do developers modify a ROM and make a custom ROM ????
This thread will help you to create custom roms
but its only for HTC devices and some other famous phones
I don't know how to add support for galaxy fit
forum.xda-developers.com/showthread.php?t=633246
Well, You can use the HTC Android Kitchen! In the kitchen, just dont let it change your updater-script to update-script.
All functions of the kitchen will not work as it is actually made for HTC phones. You can deodex your FW, add boot animation support, Change the name of the fw and Compile it!
So is there any similar tool only for samsung devices?
Nope! The HTC android Kitchen is the best option available. Most of it's features Work Man!

I found this playlist on Youtube by MarakanaTechTV which has about 18 videos about android application development.This user has some other videos on how to make custom ROMs and many other which may be useful for developers .
So here is the link for that playlist titles Android Boot camp:

[Q] What SDK should I get?

I saw a You Tube vid by AdamOutler and he said to get Eclipse classic or something. But when I go to Google Developers they give me the latest version of Eclipse do I use classic or the one provided by Google?

You can use anything.
The one which is provided by Google is a complete package, where you don't have to setup the build environment like setting up ADT plugin etc. The IDE would be ready for application development I guess.
When you download Eclipse Classic (Latest version is 4.2.2 I guess) from their website (eclipse.org), you need to download the ADT plugin additionally within the IDE and download the developer tools and then have to connect it with Android SDK. The complete steps to install are there in the developer website, so its pretty much easy the either way.

I don't really understand the vocabulary you used. (Sorry, I'm new to Android development) Is there a place where I can learn all these terms and what they do? I understand SDK though.

You just start by reading from here, and you are good to go:
http://developer.android.com/sdk/index.html
If you already have downloaded SDK, go to this website and download the Eclipse 4.2.2 Classic IDE. And go to Youtube and search videos for "How to connect eclipse with android sdk". There should be a couple.
If you don't have anything, download the SDK+ADT Bundle for Windows displayed in Android developer website (The link which I gave you first) and read the instructions and you'll be good.
It's really not matter. I think the only different is the latest version in Google Dev that you can find is well packaged and you don't need to set up most of the environment stuff.

Yes, that's right.
It comes with Eclipse + Android SDK + ADT Plugin (Developer Tools) + Latest Android Platform (4.2.2 maybe) + System Image for Emulator
So you don't have to download the Android Platform and build tools additionally after getting the SDK, as everything would come in a single package.

[Q] porting

Dear all,
I want help of you please
i am not developer i want to know only below points
1. we can port different devices rom to our device which having same chipset
2. we can port other devices rom to our e.g. samsung galaxy s4
3. if i want to make rom from scrap then any tutorial available
Please revert
i am not a developer
i want to develop something for my galaxy r becuase i dont want to loose it for some softwares
AFAIK
1. Yes
2. Yes if 1 holds. (correct me if i'm wrong)
3. this will help if you are certain to contribute towards development.
Hope it helps..!
1. Yes. The only one reasonable enough would be O2X. I tried it, but it didn't work. It uses really different nVidia libs.
2. Yes, just look at the XWLSD port. But you can't replace all libs because of the lack of NEON support. Also pay attention to the screen resolution. You will have a massive work with resizing if porting from the GS4.
3. There are many, just look into general Android dev forums, but most of them isn't applicable to the SGR.
(What Nikhil provided is a really great and huge article, hats off to the writer, but it's about application development and not porting.)

you need to use Linux Operating system for these things because it will be easy on Linux and then you can use the file which you will use in ODIN and extract system files from it using the link given above ..

1. Use these Guides.
http://forum.xda-developers.com/showthread.php?t=1736177
http://forum.xda-developers.com/showthread.php?t=1742618
2. I am not sure how to do.
3 & 4 need to build your own Custom Kernel using the sources (if some thing goes wrong you will brick your device).
5. Just delete from System Folder.

[HELP]Implement new languages to ROM. Donation availalbe

Hi guys,
Recently I bought couple of MTK based Smartphones from China, but I didn't realise they are coming with Chinese and English only. I have the language files that I want to import, but I am not sure how exactly I am supposed to include them into the ROM. I believe that I need to decompile, add the new language files and compile the ROM again, but I am not exactly sure how. I do not want to download already compiled multilanguage roms, but do one on my own, keeping all the original software that comes with the phones and only including couple of additional languages.
I am willing to make a small donation to the one who takes the time to explain everything to me step by step
Thanks in advance.

if I got you right, then first try to implement your language readability. for this:
1) copy your language font into /fonts directory
2) add font entry into /etc/fallback_fonts.xml
...(see already present lines of code to get an idea)
3) restart your phone
4) open a web page in your language to see if it is readable.

No there are no universal ROMs.
Also, bumping your own thread in such a short time is frowned upon at XDA-Developers. Please allow at least 24 hours for someone to respond before bumping a thread.

Basically because each device has a different feature set and thus requires a separate kernel. Also, to compile a kernel that supports multiple devices will drastically increase the size of the kernel. Each device has a limit to the size of the boot image that can be installed. I could go on and on about reasons why there are no universal ROMs.
I have been a Windows programmer for 20 years. ROM programming and application programming are not the same.
Ok,tnx for explaining
