I know this should be in the development forum but I never get any attention there so I thought I would ask some GNex owners I can count on
Now down to business. I have some knowledge in Java and I was looking into developing custom ROMs. I wanted to know which language(s) I will need to know to get started. I'm not talking about developing apps, I'm talking about editing framework like these highly know ROM builders do (CM9, AOKP, GummyNex, etc.) I know it it almost impossible to develop an entire ROM by yourself so I would be more than happy to use some open source code!
Thanks and if anyone could point me in the right direction to get started I would greatly appreciate it!
You need to know C/C++ for the kernel, and java for the apps, framework, ROM, and everything else. Really just java if you're gonna ignore the kernel and just play with the launcher, framework, systemUI, settings, telephony, etc.
So if I get permission to use someone else's kernel, all I need to know from there is Java?
P.S. Can anyone link me to some resources where I can get started?

Yes just ask, most people let you use their kernel as long as you give them credit. Or you just use stock kernel since you are only doing the ROM anyway. Users will likely flash their favorite kernel anyway.
If you are totally beginner, follow the hello world tutorial on Google Dev site.

There a few beginner tutorials in Google developer site. I also just googled tutorials and read read read as much as I could. Half the part is learning how android apps work, using XML for the ui etc.

Device tree is stuff like drivers and device libraries. This stuff is what gives the software and apps access to the hardware.

Well JBQ says the extract file is outdated since the 2.3.4 release and will not work properly. That binary site I linked to is one way to set it up but you will see that my method is much simpler (easier to work with), more organized, and more complete (the binary site is missing a few files). I will be maintaining my repo so essentially it will make it easier for the entire community, so everyone can glitter and glow properly
Edit: So just to be clear, completely remove your current vendor setup (dont use the binaries or the extract script) and replace it with mine.
Just updated the vendor setup with some more fixes

Read the thread linked above, all of your questions so far have been answered there already. You're going into git territory, so believe me, there are a lot more guides about git than about building aosp.

There are plenty of guides you can read. Kernel development isn't easy. It's not something you're gonna start having never done it before and just build yourself a kernel. The first smartphone kernel I ever built took me 6 months to get fully working and it was for a palm pre and I had experience building desktop kernels for various linux distros.
I like to break stuff!
The first kernels I did were based off of a guide from joeykrim and help from vampirefo. They are a PIA until you get used to it. Good luck with your endevors. Here is a decent guide to start with, change the device though. http://forum.xda-developers.com/showthread.php?t=1516051

There isnt any kickstart for making kernel for a phone if you havent built a kernel before. I would suggest looking at the community dev thread again, as most of the build process has already been gone over. Do you have a Linux distro running yet?

You can go to googles Dev site and watch the countless tutorials on android development. Also YouTube has toms of mini series covering all aspects of a android development if you are a visual learner I would highly recommend watching these series. Try to find the newest set possible. ICS or newer as the api has changed drastically and so has the adtt plugin for eclipse. Also you can find the eBook beginning android development in PDF form its pretty good and is also based on ICS and newer. Between all that you should be able to pick it up.

Why when it is open source if you read the news article all that's needed is a git cherry pick and build. Then its done.

Things are rarely that simple, not because cherry picks don't work, but because some people are in different circumstances than your own. My current phone is a HTC One running a stock kernel, and without more sources custom kernels and ROMs are something of a tricky business right now. I prefer stock when possible, so an Xposed-style framework patch is a good way of "cherry picking" what I would like in a workable manner.
Great that you're sharing the news, but you posted in every thread already and now opened a thread in dev section =/

My two cents...I know goast from the forums, and he is an advanced user and a great resource to me. He's obviously pumped up about halo, and rightly so (it's a pretty amazing innovation by PA team). I'm not attacking anyone, but I like to stay informed about new things, so I appreciated his blast out. Many devs here work demanding jobs, and donate their personal time to development, so this info may help them in this fragmented crazy fast paced world. I just wanted to thank goast for the info, and impart some positive energy here. I'm not a dev, nor am I an expert, but I share goast's passion for android and desire to learn more about it. To me, that's why I love xda...I have a commercially dead device that is still extremely viable thanks to all of the great work here. Ok, I'm done...everybody enjoy halo!
