I want to develop

Hi everybody i was wondering if there was any developer that could help me learn how to develop some roms and stuff for the sgs4g i really want to help. I'm 14 help me please need step by step instructions!!

mods delete please
another clutter prone to happen.
dear ssh678.
even though your ambition is highly admired, there are rules & regulations you need to read prior to posting.
this is probably what you're looking for.

Yeah, plus Linux is awesome anyway

well knowing how to read configure and install via source helps along with compileing kernels.. Hince why linux exp is a major plus

You need either Linux or a Mac to build from source anyway

You'll wanna learn Java, specifically, Object Oriented Programming. Stick to one of the more popular Linux distributions since it'll be easier to get your computer set up and deal with driver problems and the like. For now, maybe Ubuntu would be your best choice.

Come on, don't blame on me,but do you have any ideas of Linux otherwise this will be a thread with only HOW-TO install Linux and how to fetch repo and mod them to destroy the main reason they were build. TO WORK ON YOUR PHONE !
I don't want to be rude! Im only think that it is senseless to learn first android devin, when you never used Linux befor :/

[Q]Help getting started with ROM developement

Hi, I am interested in starting some custom ROM work for our device. I am just looking for a little bit of direction on where to start. I understand things are a bit more complicated with our locked bootloader, but I know there is still a lot to be done. What are some good places to start tweaking performance? How about graphics and theming? if there is anything else I should know that would be great. I am not an extremely experienced programmer, but I have some experience and I am fairly comfortable tweaking system stuff. Lastly, Is there any way to get an emulater going for the A2? this would be very helpful for development to save the pain of boot loops and errors on our real device. thanks for everyone's help! Hopefully our development will take off for this phone once we get the bootloader bypass working or get it fully unlocked.

I just want to get one thing out there. If you want to develop you will NEED Linux. It makes things a lot easier than using windows.

You'll also need a ROM kitchen to decompile ROM's, or you could just extract the zip and rezip... only problem is that if you make any major changes you need to write a new updater-script...

I think the way of following is similar but if you want cm7 kernel you have to download cm7 kernel source code if you need stock kernel download the kernel source code for your device
if i am wrong please correct me

the configuration of the kernel will determine what it is for, you can take htc source and build a cm7 kernel or vice-versa, you just need to make sure the config is correct for cm7 or sense or whatever you are building for, aosp/miui/cm7 use basicly the same configurations, sense, or other manufacturer made software can require special configuration.
you can pull the .config from your device as a starting point also make sure you use the gcc-4.4.0 toolchain when you build.
if you need more help you can pm me and if i can help i will
good luck

No, don't use fedora, 9/10ths of the dependicies are Debs/apt-get, and don't translate over to rpm based distros without an absurd amount of work...

Why not? I'm using with success CentOS to build Android. To build kernel you can use any distro without problem. I think that is possible even with windows with Cygwin but I'm afraid to try haha.

Google compiles it themselves on Ubuntu, all the packages can be set up with a tiny amount of work. Now if he wasn't cross compiling, use any distro you want!

[COMMUNITY PROJECT] [DEV] New Android Emulator for Testing/Developing Custom Roms

I know the SDK has AVD, but it's outdated and extremely slow. You can install custom roms on it but only older ones because its based on the yaffs2 filesystem and most current roms use EXT4. I had high hopes for bluestacks too but its locked down pretty tight and I don't see us being able to flash roms to it anytime soon. We have emulators for pretty much everything else, something like this shouldn't be too hard if we work at it. Dynamic recompilation seems to be the best way to go, but feel free to give input if you feel otherwise.
I guess our starting point should be here: http://fms.komkon.org/EMUL8/HOWTO.html
The man who wrote the guide above is some high-end developer that builds emulators for Android, but he seems to be pretty knowledgeable. He has an email you can contact him if you need help with a specific thing: [email protected].
As they come in, I'll list all the information regarding developments in this project in the post below.

Wow! Looks an excellent project for Devs
I have few questions
1. Will be there a possibility to define and emulate specific devices?
2. How ROMs are flashed, the emulator will have a recovery too?
3. How many of you are working on it?

1.) One of the goals would be hardware and kernel emulation, I would imagine they could be set as variables where you could input your own kernel and we could make some predefined hardware options for you to choose from. It would be hard but I think it could be done.
2.) I don't exactly know, but seeing as that's how we already do it we could try. Early alphas would probably be more of a "kitchen" where your menu is in the terminal and you manually put your files in the respective folders.
3.) Just me at the moment, I haven't found anyone to help. I haven't really made too much progress either, right now I'm decompiling AVD to figure out how it runs.

If this works, it would be a lifesaver. I say we should PM you any predefined device settings we want, and have a drop down list that automatically sets it. And to emulate recovery I don't see happening like on our devices, but maybe some of the wipe features, and flashing over a current rom? Also anything you need for help I can do, just ask. I'm good at design, and UI, just can't create it myself. And can you possible make it cross platform? Because I switch between windows and Linux.

I'm using Ubuntu 12.04 right now, so it's going to be Linux at first but once its stable enough the plan is to make it cross-platform. And I do need help, I need all the help I can get! Hence community project haha.

I can live with Linux at first. And I know, but I mean any help a non-coder can give. I will at least test it, and give some device specifics, but anything else that I can really do?

Either way, I appreciate the help! Ill PM you if I need a tester and you should pop in every once in awhile to see how things are coming along. I'm not going to lie, this is harder than I thought it was but it seems do-able the more I study AVD.
I'm thinking we might be able to change the filesystem on AVD to run EXT3/EXT4 and get it to run a little smoother and build it to run without eclipse, then modify it to fit our needs.

That's sound good. And anyone who would get the most use of it would be fine with a terminal based one right now, and you can work on a GUI later unless someone else helps you soon. I'll keep checking as this comes along, hopefully it won't take too long to get a preview working.

I am too up for testing!
You can use Qt for GUI, its easy.
Its based on C++ and hence is very fast than other GUI libraries.

I feel pretty confident in this project, I'm going through Androids source code starting with 1.5

I've been thinking this over, it would be much easier to add EXT3 and EXT4 support to AVD and tweak it for speed. Im working on it now, ill try to get an early alpha out as soon as I can put it together.

Linux is needed to build from source. If you are going the source building way. Let me know, I can tell you what you need.
Or you can download stock ROM's and mod them. Port ROM's from around the area, good start too.

if i were you, i would start with porting. the easiest ROMs to port are AOSP based CM7. make sure the devices are at least similar to each other, the HTC Desire HD would be a good start. don't even try Samsung Galaxy to this phone, the structures are too different from each other, and porting that would take a long time.
so read and search around the forums, make sure you read as much as you can read, and don't hesitate to refer back to the guides and posts by other users if you don't understand. and of course, there are people on this board (such as myself) who are more than willing to help you out with troubles and any further questions.
Good luck!
