Database Develop

Make a Rom?

I've spent the better part of 5 hours trying to come across information on ROM development.
My question is two part. What resources are there available to learn about creating a rom from scratch or editing an existing (including making the update.zip and signing)
Also, I assume the emulator is involved or at least could be. How do you create the system images that you need to create a custom avd from the zip's that you find roms in?
I have a feeling there's a lot I don't know. Perhaps the answer is in front of my face, but I've been looking for a long time and definitely have tried so please don't just say "use the search fuction" or "google it"

Devs normally don't like to share the info but there's a guide here:
http://ctso.me/2010/02/building-an-android-rom-–-part-1-5/
But the info is in other places to the google-android page might have some info to. You must be using a linux OS to actually build anything, windows is a no-go...

Quick and helpful, thanks!
Luckily I did just put the latest ubuntu on my laptop.
If anyone else wants to chime in with some helpful resources please do!
If some annoying little 14 year old made a hero rom, it can't be all that complicated.

He was just lying, he spammed various threads while talking about other devs.

first he's 14 then he's 12...next he'll be a spoiled 8 year old. you just watch.
I'm glad I checked this post. I was curious about ROM developing myself. Thanks for the post.

Is it me, or does that guy have more then one account...

At the risk of taking this further off topic... what guy?
But really my main concern is how to make a rom so, any other help from anyone would be good. Thanks!

Bump?
I'm sure somebody knows something

If you would like to compile android source code (create a rom from scratch) the best place to start would be:
http://forum.androidspin.com/showthread.php?t=2004
or
Chris Soyars' blog: http://ctso.me/2010/01/building-an-android-rom-part-1/
OpenEclair github readme: http://github.com/openeclair/android
Official AOSP Guide: http://source.android.com/download, http://source.android.com/download/using-repo, http://source.android.com/documentat...ding-for-dream
Instructions on creating and signing update.zip files can be in a few places herre on xda. Check the themes section I'm pretty sure I saw a few there.
Also, I assume the emulator is involved or at least could be. How do you create the system images that you need to create a custom avd from the zip's that you find roms in?

Install the rom on a handset & do a nandroid backup. It will produce the img files you will need for the AVD

Dude, you're awesome, thanks!

[Q] Rom Cooking .

Okay So Basically I Just Started Working With The Rom Kitchen Can Someone Give Me Some Pointers On How To Get A Specific Rom Booting or Anything Else I Need To Know ?

Man do yourself a favor a READ and search for awhile.... all you ever do is ask for handouts. Development is not easy. Its not just a matter of asking questions. You had 134 views of this page before I responded. That's 134 people that didn't wanna help you... if that doesn't say anything I dont know what will.

There is no specific guide to porting, developing, etc. As Matt said, read. And lots of it. I personally started by playing with aosp and CM source, but you currently cannot due to kernel.org being down, but you can go to my signature and read my thread on compiling aosp gingerbread on Ubuntu. It will help you understand how some things work. Try taking apart a ROM and learn the layout of the files and read up on what different folders and files are. The rest is really just trial and error. I started with no experience at all. Hell I still don't know any coding languages, but that's why I'm in college.

How to start building ICS from sources?

Hi,
some experienced dev can post here some instructions, hints, or anything that could be useful on how to build ICS from sources?
I'm not talking about anything you can find here:
- downloading sources http://source.android.com/source/downloading.html
- building sources http://source.android.com/source/building.html
I'm talking about lunch configurations, kernel to use, init script, proprietary files, etc... (I really can't find any guide for this kind of things.)
I never started a new build configuration, I only used "ready-to-build" solutions like CM, and I'm very interested to learn something new.
I think this is a good way to start to work on ICS for our device and share our findings to quicken the work of arcee.
M.

There are some great articles on "porting android". I guess you could start there, that's where I am
You may also want to check out the reading list from CyanogenMod:
http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S_II_(AT&T):_Compile_CyanogenMod_(OS_X)
It contains two 1 hour long video introductions to porting.

thank you. that's exactly what i was searching for.
Apparently I was searching with the wrong keywords

[Q] publish the source code of Corn Kernel

Hi there,
I'm looking for the source code of Corn Kernel, especially the version 7.0A.
I already tried to compile the kernel from Samsung with no success.
If by any chance the author can share his code this would be great for me.
Thanks

Might want to check with mtcarey here
http://forum.xda-developers.com/showthread.php?t=1294477

I don't believe they have enough posts to post in the development section, if I remember right it has to be 10

Oops, on the app didn't see post count. Could prolly send mtcarey a pm

Refer here. MtCarey explains how to compile KK4.

Actually according to GNU/GPL licencing, all source code must be made available to the public for anything built on or modified from software built with that licence and the licence must carry over.
basically if you build it from a GPL licenced source, you must provide your source for your changes/additions.
But im sure if you send the dev of the kernel in question, he would be happy to abide. (by xda rules he should).
sometimes with modifying kernels/roms of leak versions, and software for which source has not been provided to us, we are able to change 90% less, and are breaking GPL, but we dont really have a choice in the matter. well... we could just not mod it.. LOL.

he says in that, that there is much more to tweak to get it proper, but those are the 2 main things missing to get it to boot. not exactly a how-to compile guide.

Hi Guys,
In response to the quote below, I already tried to compile other kernel with some success. I managed to do that with HTC kernel by following the instructions. The explanation MtCarey gave is more like a hint or some info. Even though the info might be good enough for experienced kernel developer, I'm still not experienced enough.
All I'm asking weather the full source code with minimum modification can be contributed to the public so we all can have the benefit of it.
And of course! many thanks for MtCarey if he's willing to do that.

did you PM him? the un-modified stock kernel or unmodified corn kernel??...
and if you arent that experienced with it... why?? learning?? most of the kernel devs hang out in irc and talk and help kernel developing.. go make some friends.

Where can I get the information how to get to the irc?

Built AOSP extended, sort of works. Someone give me a clue?

I posted in the main Android forum for help, but it's so busy there! I figured I may get some help in a more relevant device community. To avoid reposts, here is the original thread:
https://forum.xda-developers.com/android/help/help-build-source-failed-make-otapackage-t3831440
Big thanks to Psy_Man, I used his device tree and kernel to build.
If anyone wants to try my build it's here (use opengapps nano, stock seems to crash the setup wizard, probably because it removes webview). Everything seems to work but I have no clue how to fix anything so don't bother sending me logcats

Maybe (very probably) I missed something but in your thread asking for help you say the problem is build doesn't complete, error at 99%, but then you do have a build that I think (from what some guys say in telegram) boots and all. So what do you need the help for exactly?
On the other hand I always found help posting my problems in the complete android rom development source to end thread, the one with like 900 pages and going....
https://forum.xda-developers.com/chef-central/android/guide-android-rom-development-t2814763

you should post on development section, if you want to keep updating the ROM, many people will try your ROM and help to test it and maybe will help for the solutions too.

I am a complete Linux noob, I have literally never used a compiler before in my life. Yes my build works and boots (which I am amazed at because it's my first try) but I need help in understanding why one way worked and the other way didn't. Thanks for the tip about the development guide

I would post there, need to get my post count up first :laugh:

I made another test build after setting up my own github account, this time no compile errors at all, and I got an xxx-UNOFFICIAL.zip this time like I'm supposed to! Who knows why it didn't work the first time, but i'm (very) slowly getting the hang of this

Have made a build that works properly now, will make a dev page as soon as i'm allowed. if anyone wants to try it out it's here https://drive.google.com/open?id=1SQGaI4U0KeQQKJwq6EyRsa2VQph91oHA
