Hi,
I have forked someones entire repository (which I tested compiling before forking) into my own here:
https://github.com/SUroot
This is android 2.3.3. There are lots of commits I wish to keep (including a few minor ones of my own) but what I want to do is update this to 2.3.4
I have the above repository sync'd locally. I also have a pure AOSP sync'd too.
I thought that android_frameworks_base was solely responsible for the android version, but if I swap out the folder in my local repository with the AOSP 2.3.4 one, when I lunch, it still says 2.3.3
I've been googling furiously but I never seem to find answers to my questions on this subject very easily, so I hope someone can help me please?
What exactly is needed to be updated to change the android version and how do I keep the existing commits?
I am an absolute beginner at this so please be gentle
Thanks in advance
Dan
hi,
I think it's in system/build.prop
Thanks for the reply, but isn't that just what it displays as? I thought that was only generated after the build? Theres no build.prop in /system/ on my local repository.
I'm trying to better understand how the devs around here do what they do. I'm an Electrical Engineer and I make no claims to be a proper software developer. I know my way around C, Python, and Bash. I know my way around git and have worked with various build/release processes before so I can stumble through some CMAKE and MAKE build processes. Currently I have installed the the android SDK, compiled AOSP master branch and run it in an emulator. I've also compiled Cyanogen mod repos for generic-eng though I haven't gotten that to properly boot on an emulator yet.
So that's an idea of who I am and where I'm starting from. Now for the questions. I figure if I can understand the build environment and process I can learn quite a bit from the large history of available changes, especially since there is an Atrix Dev Team for Cyanogen.
Cyanogen Mod
I can't tell which repo's here are pure AOSP, modified AOSP, or from scratch pure Cyanogenmod.
Do the CM repo's track AOSP as a remote branch?
If yes, does that mean I can build pure AOSP from CM repo's via repo?
If no, how can you tell where in the AOSP development cycle the CM repo's fork from?
Are 'nightly' builds by definition a repo sync of the non-release base simply built as is? AKA for an Atrix nightly, you would checkout the gingerbread, sync, and build (assuming you're setup for building in the first place)
Are Official release only tracked via git tags? IE for CM 7.1 it's not really tracked on the manifest so would you need to find the proper tag and do a repo forall git checkout -b cm-7.1 or similar? I'm asking how you could build a previous release which should match the official release.
Atrix Dev Team
Similar to the CM Question, do these repo's track CM as their base repo's?
Could someone describe the typical development cycle of how the Atrix port is handled on top of a moving CM development? I'm a little lost as to how AOSP -> CM -> Atrix dev works out. If I checkout the Atrix manifest to gingerbread and perform git diff with the /m/gingerbread (I beleive the CM tracking branch) I see no differences. Are Atrix-Dev-Team and Official CM repo's simply fully in sync at this point?
How would I setup my repo to match a given Release (as in what tag or manifest I understand git)?
How would I setup my repo to match a given Nightly (as in what tag or manifest I understand git)?
As above, could you build pure CM from the Atrix repo's? This very well could be answered with the above questions.
Generic Info
What's a 'kang'?
My guess would be it's a build produced from the source repositories and not an official release by the developers.
Exploring the AOSP I noticed a separate kernel download link. I know CM uses a custom kernel but is that included in the default builds or is that typically flashed and managed separately?
After I'm familial with the whole process, and knowing what I've stated above what's the best step form there to be able to help contribute? Right now I've picked up a book on programming Apps on Android so I can learn the tools and some Java and I've had c++ on my radar for some time.
Thanks for your time. I've tried to get relatively well informed before I post questions.
So ... am I asking these in the wrong place?
Hello everybody.
I have a noob question about compile cyanogenmod for my new device.
Now, i have: CMW recovery, Kernel source code on local computer, full repo cm source + toolchains.
How to add my device tree, kernel source code to CM source and compile CM7 ROm?
Thanks you, cheer
Anyone here?
Did you figure it out yet? I asked the same question and am waiting for an answer, tho I'm on CM 10, HTC Vivid. If I figure it out I'll post back and try and help.

I met the same problem, does anyone can help?
Do you have a device tree? Or do you have an unsupported device? If you have an existing device tree from some other ROM, etc, then you just need to edit your .repo/local_manifest/roomservice.xml to pull in the trees that you need.
If you need to create a device tree, then it gets not complicated, as each device is different. The basic process is to create the necessary directories (device/manufacturer/model, kernel/manufacturer/model (may need to be kernel/manufacturer/device_family/model, for reference to that, see CM's repo for the LG G3) and finally vendor/manufacturer/device.
After you have the directories setup, you will need to actually start building the tree. The easiest way is to copy another devices files into your devices tree, and then edit the files. The closer the device you copy in is, the less work you will need to do to the files. Refer to sites like gsmarena.com, PhoneArena.com, etc for phone specs.
That's about as far as I can take you without dealing with a specific device. If you need more info, post back here with your questions, and post your device specs, or at least the model number,and I'll see if I can help.

I have a mt6750 devices... And there is a device from my company manufacturer.. Its a mt6750 device, it have cm device tree.. Both device working on same rom.. I can port that device rom but it always give me bugs.. So my question is how to use it?
Quick question.
Can you download one specific apk from Android source and then just compile that or do you have to download the entire source, compile the entire rom and pick out the one apk?
Id like to look at adding/merging some things to Mms.apk which I cant do just through apktool/xml but if it requires a full build environment Ill have to add it to the pile of things to get round to
Never really looked at compiling from source, tend to stick to what I know (which isnt a lot!)
Hello,
I'm trying to build a device tree for the Samsung Galaxy Tab A 9.7 (gt510wifi), by following CyanogenMod's porting guide here. I've managed to get a basic device tree going inside CM12.1's source tree, but I'm stuck at the part where I need to create the extract-files.shand the setup-makefiles.sh. The guide says to use other device trees as a reference for creating these scripts, but from what I can tell, each script is vastly different due to device discrepancies, and I'm unsure what to do at this point. I've searched everywhere online, but there doesn't seem to be any documentation whatsoever on how to create these files.
I'm no stranger to porting ROMs, as I've built SlimLP for my other devices, but I always had a pre-built tree created by another developer that I simply renamed files in to get it to work with SlimLP's sources.
Any help is greatly appreciated
