I am new in XDA developer forum. I knew java and android at the immediate level. Now I'm interested in creating my own Android smartphone ROM. After searching in google, I see that there are a thing which is called "Default ROM" released by google. Base on this ROM, different companies created different ROM in their own style such as Sense, Motoblur, TouchWiz, etc.
So where could I download such a default ROM, and how could I begin with ROM developer. It is kind from my if anybody could give me a tutorial.
(Sorry if the question is exist in the forum, because I could not find it)
Thanks a lot.
Best regards,
me too, i have the same question, can someone help? thx
Your best bet is to have a look at compiling the aosp from source which you will need a Linux os for. The android sdk is a good place to start.

Also are there no different way but Linux OS?
I still have the Android SDK, but do not know how to begin to custom a ROM via code.

Yes to build android from Google's source you will have to have a Linux os. Either stand alone Linux or a version like ubuntu

One place you can start by checking and has a lot of good info is http://freeyourandroid.com/
I learned how to port from them although I still need to ask questions but it can get you started.
If you just want to get Ubunto going in a virtual machine for now and have NO IDEA take a look at this: http://theunlockr.com/2010/03/26/ho...om-for-android-part-1-setting-up-the-kitchen/
Old release links but Ubunto will update itself
hey can we create our own version of android like, for example, (Android 4.3 dev by someone not in the google android company)....
Short answer: No
Think yourself if that would be possible then why would everyone stuck on jellybean.

Technically there is no reason why not Android is open source and you could freely fork the code and start building your own modified version and then distribute as you see fit.
This is after all what the likes of Cyanogen Mod do, but at the end of the day you would still have to work off a current version and mod to your needs.

So, what you mean is that all ROMs actually are android version, right?
Then what does an android version exactly mean?
Does it define a unique -
ROM +kernel
ROM
Kernel
ROM +kernel + extra innovation

Yes, all ROMs which are released are based on Android Open Source Project's (AOSP) source. Initially Google have to release the source (Latest is Android 4.2) and then manufactures like Samsung, HTC, Sony, LG etc. works on their own to provide the updated Android version to their phones skinned with their proprietory UI's or themes.
Android version exactly means changes in features added by Google itself, which are incorporated by Manufactures when they push updates to their phones.
ROM is actually the term used for your Operating System. Kernel is complete different subject related to ROMs, it works as the medium of communication between your hardware and the operating System thus involving drivers and CPU controls.
I understand this is a UI preview, but will the full build be completly linux and use a linux kernel? I really don't want it to use anything Andrtoid related, otherwise it wouldn't truely be linux. :/
They have said they are only doing it at the start for compatibility.
And technically android is full Linux and therefore Ubuntu is now.

Hello,
To be honest, both Android and Ubuntu are both Linux based Distributions and both use a Linux kernel. In fact, both distributions branch from the same Linux source tree.
With this said, the touch preview uses the CyanogenMod 10.0 Android fork as a base. Ubuntu is ran inside of a chroot, This means that they are both using a shared kernel.

you dont like android ? they both from linux
I think the confusion here is that when most people who have used a Linux system in the past, prior to Android or didn't know that Android used the Linux kernel, they were actually using GNU/Linux, so they think that is what Linux is. Some people may even mix up that the X server is also a part of Linux.
But Android isn't GNU/Linux so when some one says 'Linux distro', they are probably thinking of a GNU/Linux distro, like Debian, Slackware, Fedora, Ubuntu, Red Hat, Mint, etc, and not just an OS that also happens to have the Linux Kernel in it.
So the title of this post probably should have been GNU/Linux or Android.

By that logic, technically, Android isn't Linux (since Android isn't a Kernel), rather Android uses Linux.

Exactly, ubuntu isn't Linux, it is GNU/Linux meaning it runs the Linux kernel (Just like android does), and contains the GNU utilities and software that make the system usable. Android is also GNU/Linux, but android has less GNU software and most "apps" are run using dalvik. So really ubuntu and Linux are both running "Linux Kernel" but aren't just Linux. Pure Linux would just be the kernel as Linux isn't an OS.

And that is why they are called Linux distribution.
And even calling Android a distribution is kind of a loose definition of what a distribution is and was. It used to be a long time ago that a distribution was intending to distribute Linux, which the only way Linux would be useful is to also have several applications and modules that make a useable operating system, that is what a distribution was. Android doesn't exactly fit that, users are not even really aware of or deal with Linux related things, although some of the apps they use may access parts of the file system (sysfs, procfs, etc), and users can install software that gives them access also. And it could be argued too though that Ubuntu doesn't exactly fit this either, since there are not stripped down versions and they are starting to force dominance of certain packages, but they still allow for low level access.

This is what Richard Stallman has to say:
http://www.gnu.org/gnu/gnu-linux-faq.html#linuxsyswithoutgnu
Are there complete Linux systems without GNU? (#linuxsyswithoutgnu)
There are complete systems that contain Linux and not GNU; Android is an example. But it is a mistake to call them “Linux” systems.
Android is very different from the GNU/Linux system—because it contains very little of the GNU system, only Linux. Overall, it's a different system. If you call the whole system “Linux”, you will find it necessary to say things like, “Android contains Linux, but it isn't Linux, because it doesn't have the usual Linux [sic] libraries and utilities [meaning the GNU system].” Android contains just as much of Linux as GNU/Linux does. What it doesn't have is the GNU system. Android replaces that with Google software that works quite differently. Thus, what makes Android different is the lack of GNU.

To rephrase the question: Will the apps and system functions use languages other than java? In desktop Ubuntu, there was a wide assortment of languages the could be compiled and run as scripts. Will we see the same multi-language support on the full mobile distributions?

It's hard to be completely certain what Canonical will do, but it is very likely it will support multiple languages.
Technically you can build applications on Android in any language you want provided there is a native runtime module or the language compiles to native libraries, but Java always sits in the middle.
From what I have seen with Ubuntu Touch, Java is not even included by default, I saw it pull openjdk when I installed Eclipse, and that Java is not even the same as the one Android uses.
Currently the only API that draws to the display is Qt5 and QML, other APIs like GTK+ and even Qt4 try to use an X server which doesn't exist currently, although you can route to a remote x server and display applications remotely.
But in terms of language support I've tested c, c++, JavaScript, python, bash scripts and java, and I'm almost certain perl will work. Again the problem is though, if they don't have Qt5 bindings they can only display on a remote x server or in a remotely connected terminal and not on the device.
1) Linux is not, I repeat, NOT an operating system. It's a kernel, which is the core coding which an operating system is based around. The kernel acts as a medium between software and hardware.
2) Ubuntu, Android, Fedora, Arch, WebOS , and etcetera are not Linux. They are Linux based operating systems that are built upon the Linux kernel.
3) BSD, Free BSD, Mac OS X+, iOS, and Solaris are all UNIX based operating systems. Linux is a clone of the UNIX kernel.
4) The GUI is not part of Linux. X server is a back end for the X11 window service. And is not included in the core kernel itself.

A "distro" is usually made up of: The kernel (linux), the GNU coreutils, a package manager, a Desktop Environment, and some integrated applications. "linux" is a kernel. You can replace the kernel with any other compatible kernel, as Arch/HURD, Debian/kFreeBSD, and Arch/BSD have proven. Don't confuse linux with GNU/Linux.
Android is merely a distribution of liunx with a different set of coreutils, tablet based applications, and the play store as a package manager, and Dalvik VM.

Hi
My goal is to build Ubuntu Touch for the Ideos X5 U8800. So far, I have only had trouble finding and setting up the source for a cm-10.1 build. Finally, I gave up and built cm-11 using Blefish's device source tree. Everything works just fine.
So the question is: Can Ubuntu Touch be built using cm-11, or is cm-10.1 the only option at the moment?
Best regards,

Libhybris is being utilized by Ubuntu for Devices, Sailfish, Open webOS and others to form a base layer compatibility with Android hardware drivers (above and beyond just the baseband [radio]). This is what gets the ports to work with Android hardware... http://en.wikipedia.org/wiki/Hybris_(software)
The mainline efforts have focused on Nexus hardware and seem to have formed a consensus that CyanogenMod 10.x is the best jumping off point.
Debdroid V4
Linux Chroot Daemon for Android
Supports Android 2.3 through 5.0
Debdroid is a tool for the Android platform which runs a full Linux distribution as a daemon.
Any rooted device can run fully supported ARM distributions such as Kali, Debian, Ubuntu, etc.
Debdroid has been successfully tested on Android 2.3 and up to 5.0. Confirmed working on the N9.
How To Install:
1. Download the git repo
2. Place ARM image at /sdcard/linux.img
3. Flash the zip file in twrp
How To Use:
1. debshell "any command goes here" - run any command under linux
2. debshell "passwd" - change root pass
3. debshell "/etc/init.d/ssh restart" - starts ssh
4. debshell bash - full access to a bash chroot

If you find this tool useful send a coffee my way
DONATE TO THE DEBDROID PROJECT
There is a project that is doing this too made by Offensive Security (The guys who make Kali). It's still in beta, but there's some pretty cool stuff! There is a custom kernel that adds other features as well.
Site: http://nethunter.com/
Github: https://github.com/offensive-security/kali-nethunter
I know, I'm part of the project!
I've worked on BT5 ARM a few years ago.
From my understanding the Nexus 9 builds of nethunter aren't fully functional yet.
This can also be used with a barebones debian system for apt, etc.
What status is the N9 with Nethunter?

Mostly working. Everything except the external wifi is running fine (from what I understand. Someone else makes the kernels.). NetHunter itself is running fine, but the custom android kernel is where the good stuff is!
Supposedly the N9 supports monitor mode with its built in chipset. We'll have to try that later though.
Awesome, going to try and contribute to that.
This lightweight install is multi-purpose and can be used for much more than just booting Kali

Yes and no. NetHunter itself will work without the kernel, but you won't get many of the added features that the (still incomplete) kernel provides.
