Getting Android source in Eclipse on Windows 7 [solved]

Hi all, I'm just starting getting into App development and I want to attach the Android source code into Eclipse so that I can reference it locally. Is there anyone here who has experience doing this on Windows who is willing to walk me through it?
Alternatively, I'll go it on my own if someone could help me get past this one roadblock. Thus far I've installed Python and msysGit (and updated my PATH variable accordingly) so that I can use git and repo. Something isn't working however and repo runs into an error that I can't seem to figure out. I'm contemplating uninstalling all that and starting from scratch with Cygwin.

Here's a tutorial on setting up Eclipse on windows (albeit over a year old so no guarantees) link
personally I would dual boot linux... it was a breeze setting it up and there's plenty of tutorials for that.
You could install ubuntu (i think) side by side with win7 using wubi, as if it were a program or something. That way you're not messing with partitions.

I already have Eclipse set up. This is not the problem. I'm having trouble downloading the Android source code - NOT the SDK - on my Windows PC. Specifically, I always run into errors when I try to use "repo init -u blah blah" as instructed on the android source page. If someone has successfully done this on Windows, I'd like someone to give me some guidance, because either I'm doing something wrong or my setup is not correct.
Right now I'm trying to use Cygwin (basically creates a linux environment inside Windows). The last time I tried using repo, I got this:
EDIT: Code removed. I found a solution, outlined below, for anyone else who wants to get the Android source into Eclipse.

Okay, I got the source code, it was actually pretty easy to do, and I didn't even need repo to do it . For those who may find this useful, here's how.
0. It is assumed you have already installed both Eclipse and the Android SDK. If you don't have those yet, download them and set those up. If you aren't on Windows but still want to know how to get the source and import it into Eclipse, you can skip step 1.
1. Install Cygwin on your computer. During the installation, you will be presented with a package explorer and you can choose specific packages to install. Choose whatever you like, but make sure to include automake, bison, curl, flex, gcc, git, gnupg, python, zip, and an editor of your choice, like nano or vim (you can use the search field at the top to find these quickly).
This will basically give you a Linux shell on Windows whose root directory is something you've designated, like C:\cygwin.
2. A few more things to set up. Fire up Cygwin and make a bin folder in your home directory. Add this directory to your PATH variable, then cd into it.
Code:
mkdir ~/bin
PATH=~/bin:$PATH
cd bin
This blog post has code for a python script that will be used later. Make a new file using an editor of your choice. Copy the code and save the file as anything you want (I named it "pack.py"). When you're done, cd back to your home directory.
3. Downloading source. From your home directory (or a subdirectory if you wish), use git to clone the platform frameworks base into a new directory (here I've called it "android").
Code:
git clone http://android.git.kernel.org/platform/frameworks/base.git android
cd into that directory and examine the git tags.
Code:
cd android
git tag
You'll get a list of tags. Choose the one that matches the API level you want to build your project(s) in. I'm using API level 10, so I chose android-2.3.3_r1. That's what you're going to check out.
Code:
git checkout android-2.3.3_r1
4. Reorganizing the source code. You need to locate all the java source files and restructure everything into a directory structure that matches the package naming. Fortunately, that script from earlier does exactly this and then zips it up into a nice little package for you called "sources.zip".
Code:
python ~/bin/pack.py
5. Move this zip file to the proper SDK platform folder. Since I downloaded sources for API level 10, I want to move this zip file to
Code:
C:\android-sdk-windows\platforms\android-[B]10[/B]
You can do this with your regular old file explorer on Windows. Extract the contents into a subfolder named "sources".
6. Get Eclipse to recognize them. Open up a project (or start a new one) whose target is the API level you just did all that stuff for. In the package explorer, right-click the project root and click "Refresh". Now when you browse the class files under project-root/android 2.3.3/android.jar/whatever, you'll see actual source code instead of that nasty "Source not found" page.
Enjoy ^_^

[TUT] [SABERMOD] How to Compile Your Own AOSP/CM Custom Kernel

Since this is in the Moto G (Falcon) forum, these steps are for the Falcon. This does not mean that it isn't the same for other phones! Even if you don't own a Falcon device, feel free to ask for help here!
Prerequisites:
- You must have a Linux firmware running on your computer (I suggest Builduntu because you can skip the next one [build environment setup])
- Build environment setup (Put the this in terminal and follow instructions)
- Patience and a heart willing to learn
- You need to know the languages C, C++, Java, Ruby, Python... NOT! You don't need to know ANY coding languages.
[MOTIVATIONAL SPEECH]
Truth be told, when I first started out developing, I knew NO coding languages except for HTML and a little bit of Java. Both have nothing to do with kernels! I actually learned how to do this when I suffered from a concussion. So if you really want to learn how to kernel dev and you give up halfway, just know that a 14 year old kid with a concussion beat you .

WARNING: I am not responsible for any damages to your phone or computer or pet unicorn. When you modify the wrong partitions, set too many jobs for your compiler etc., that is not anyone's fault but yours.
Your Personal Handbook to the Following:
- Anything inside "CODE" boxes, type it into your terminal. If you can't find terminal, then press CTRL, ALT, t.
- If I were you, I would write these by hand instead of copying and pasting it because after a certain amount of times, you will remember the linux commands and it will be easier for you to compile more kernels for different devices
- Use this thread as a "Help Me" button. Ask for help!

A New Beginning:
Let's start out with something simple, getting the actual code:
Code:
git clone https://github.com/cyanogenmod/android_kernel_motorola_msm8226
This could range from 3 minutes to 2 hours! Read a book, count your fingers, watch ****, and wait patiently.
Once that's done, open up your file manager and rename the folder (should be android_kernel_motorola_msm8226) to whatever you want. I will refer it as "mykernel".
Click to expand...

Pokemon!
For this tutorial, we will be using a Sabermod 4.7 toolchain to compile. I WOULD teach you how to compile with 4.8+, but it creates errors that will take even longer for me to write about sooooooooo :fingers-crossed:. Now to get the toolchain:
Code:
git clone https://github.com/SaberMod/android_prebuilts_gcc_linux-x86_arm_sabermod-arm-eabi-4.7
Rename this to whatever you like, but I will be referring this as "toolchain"
Now go into you folder where the kernel source is stored...
Code:
cd mykernel
Click to expand...
Click to collapse
Almost done :
Time to set-up the compiler!
Code:
export CROSS_COMPILE=/home/*your linux name*/toolchain/bin/arm-eabi-
This tells the toolchain that "OK, we want to make ALL this code here into a kernel".
This next line tells it that your defconfig (the toolchain's manual for compiling the kernel) that it's in the arch/arm/configs folder.
Code:
export ARCH=arm
Now to tell the it what the defconfig is!
Code:
make falcon_defconfig
Hehe, now to the hardest part of all...
MuHAHHAHAHa
Click to expand...
Click to collapse
THE HARD PART
You ready for this? HERE IT IS! TIME TO BUILD THE KERNEL!
Code:
make -j4
Now sit back, relax, and watch the code! Or you could read a book, watch ****, count your fingers, play with your toes...
If you have an error during the waterfall of code, find the part where it actually says *error* (you'll probably have to scroll upwards) and search it on Google or post it here.
Click to expand...
Click to collapse
THE EASY PART
If you manage to get something that says "the kernel zImage is ready" or something like that, that means you've made it!
You have officially compiled your own kernel from source! Now you need to put it in a flashable zip.
Download this file and open it up, but DON'T EXTRACT IT.
Now go to your kernel source then "CTRL + F" and search for "zimage-dtb".
Find it and put it in the "kernel" folder of "FalconKernel - Signed.zip". Then "CTRL + F" and search ".ko".
Copy radio-iris-transport.ko and put it in the system/lib/modules (not pronto) of the zip.
Then find wlan.ko and rename it to pronto_wlan.ko. Copy and paste it in system/lib/modules/pronto of the zip.

Now you can put it on your phone and flash it! ​

Here I will walk you through on how to add the intelliplug feature made by @faux123
First, fetch my Green Machine kernel source (go into your kernel folder in terminal):
Code:
git fetch https://github.com/YoshiShaPow/green_machine_falcon
Then you could cherry-pick (basically copy) all my cherry picks for intelliplug from my source.
If you do check my source out, you can see there's a little link to a history of commits near the middle of the screen, right above the files/folders. You can see at this page of my features history, you'll see a bunch of commits for intelliplug. I will use those commits and copy it to your own kernel.
This copies the initial coding/first commit of intelliplug!
Code:
git cherry-pick 01a850f
This cherry-picks the remaining commits so that your newly added intelliplug is updated.
Code:
git cherry-pick 6623f2f^..4e1ece7
One more thing though, you need to add the line to compile intelliplug!
Almost all things compiled along with the zImage are in a file called defconfig. What a defconfig does, is tell your machine to build certain modules, kernel objects, drivers, governors, etc.etc.etc.. Now, all of them are found in the folder
arch/arm/configs
Click to expand...
Click to collapse
As stated in the OP, you have to modify the defconfig you use. (CM11 Kernel is falcon_defconfig, Gummy Kernel is msm8226_mmi_defconfig). Open up the corresponding defconfig and add this to ANY line anywhere.
Code:
CONFIG_INTELLI_PLUG=m
Now, for those who are familiar with "y=yes/n=no/m=maybe", you'll see that I specifically told you to put the "m=maybe" one. That's because when you compile the kernel again, right after you're about to start your build. Since you put that "m", the terminal will prompt you with a "y=yes/n=no" question on whether or not you would like to add the following feature. Since you would like to add the feature, put in "y". Later on when you feel more comfortable with adding features to your kernel, you can go back into the defconfig and put it as
Code:
CONFIG_INTELLI_PLUG=y
So that it will compile it without asking, since you have given it an answer.
Now you have officially compiled a "Custom Kernel" and with the knowledge you know, you could create a feature packed one by just kanging (copying one's work/features).
Always remember to
Code:
make clean && make mrproper
after every build to prevent errors and such!

Nice guide!
I think it lacks one thing- how to modify the kernel.
The guide only mentions how to compile a preconfigured kernel, just the way it is. Modding kernels and adding new features (like OC, schedulers, s2w etc.) is the cool part about making a kernel yourself IMO.
Just a suggestion.

Does "fastboot boot kernel.img" work from bootloader mode?

Also why wouldn't the any kernel zip work if I decompressed and compressed it again. I did that before this thread and it didn't work.

I specifically said in the tutorial nor to unzip it... The zip is already signed (a prerequisite for flashing) and unzipping will break it.

Probably a gcc error... I'd try compiling with a 4.7 toolchain. And also, make sure you're using the msm8226_mmi_defconfig since gummy's different

@YoshiShaPow thanks for the guide. I'm using it to begin fooling around with some building.
May I be a pain in the *** and ask you for a lil help? If using the file you provided to insert the build, I get trouble with wifi (in latest Aospa). I don't expect you to solve that, but I was wondering how to make out of the zimage a boot.img file, but I've read around the ramdisk needs to be merged into that, and honestly I'm not so sure how to do that. I found some guides, but none of them is specific for falcon, so I might be goofing around if I follow them?
Also checked the flashing script in the file you provided and noticed that it makes a boot.img on the go, but couldn't figure out how to reproduce that either.
If what I'm asking is too hard or long to be answered , I understand :good:
Edit: now I tried building with Linaro and after sorting out a couple of errors, voilá, I got a build. But again, my wifi gets smashed. Everything else seems to work fine, but when I try to turn wifi on, it's dead, nothing happens. My ideas: could it be something about the way the kernel's flashed skipping a boot.img (ramdisk?)? Is it something about AOSPA (think it shouldn't since it uses CM kernel)? Or should I be looking into my build, making a logcat about the issue and working it back?

Uhm, no, I followed that part step by step. I did it once more to double check, and I'm still in the same place. Actually, I suspected something and tried your kernel (TGM) and had the same problem (WTF?). I need to try wiping everything and reinstalling aospa to make sure there isn't some other thing going on down there.
But it's ok, I'll figure it out somehow. What I'd really need if you can point me in the right direction, si how to step further into building a boot.img
Or for that I MUST follow the official CM method, meaning syncing the full repo and building just the kernel?
Thanks for your help!

I'd guess it's not about the method. I think there's no CM official support for this device. Do you have any unofficial source to build from (Github)? If so, I guess you could try.
Edit: should check if Sabermod is compatible with the device's arch too.

Guide - Introduction to Rom building/development

Hello everyone.
I’ve decided to build this tutorial in order to assist all developers and builders into the ROM and kernel development. I’ve felt motivating into writing this small post because I feel that the current information available is confusing and also do not provide the set of skills and information to help someone in the first steps.
This tutorial will be divided on:
The Machine Configuration
The tools of development
The Source
Hardware
Software
What to do to be able to Innovate
The Machine Configuration
In order to have a good machine configuration you should select your distro based on the packages which are provided to developers. In my opinion the best distros are Fedora and Ubuntu. It is important to learn a bit how Linux works in order to fully understand what we are editing as Android is nothing more than equivalent Linux system where you run java on a virtual machine. In other words, you’ll understand with time that many parts which are used on Linux Operating system it is also used on Android Operating System (example: bionic, kernel libs).
After you installed your Linux system you’ll need to prepare your machine for building. For that you’ll need to install the following packages:
Code:
sudo apt-get install git ccache automake lzop bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 g++-multilib python-networkx libxml2-utils bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev squashfs-tools pngcrush schedtool dpkg-dev liblz4-tool make optipng maven
sudo apt-get install openjdk-7-jdk
Code:
sudo apt-get install android androidsdk-uiautomatorviewer android-copyright android-src-vendor android-emulator android-tools-adb android-headers android-tools-adbd androidsdk-ddms android-tools-fastboot androidsdk-hierarchyviewer android-tools-fsutils androidsdk-traceview
After you have the basic packages installed we are going to add the repo instructions to you git in your machine. Basically this will interpret the source information when you are syncing new code from google repos and we’ll add to the folder /bin/repo.
To do that we’ll run.
Code:
[B]mkdir -p ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo[/B]
And run the /.profile. Basically this command will reload information of the new settings for your profile, where it’ll read the folder ~/bin/repo information for all situations. In the future only makes sense to load again in case you have added a new repo instruction.
Code:
[B]. ~/.profile[/B]
Now we are going to sync the source code. I’ll use here as an example CyanogenMod as I believe to be the easiest for anyone which is starting. Lets imagine we are going to put all the source on a folder named cm, you’ll have to just run the following commands.
Code:
[B]mkdir ~/cm
cd ~/cm
repo init -u git://github.com/CyanogenMod/android.git -b cm-13.0[/B]
So in order to explain what we’ve done here by steps. The repo init –u basically is a command instructing to go to the GitHub on that specific location and extract what is available on the cm-13.0 branch regarding to manifests. So basically it’ll automatically push the file which has all CyanogenMod source to .repo/ folder with the name manifest.xml
After you have loaded this command you’ll run the repo sync , basically this command consists on downloading all the code into your building folder (in this case cm folder).
After the repo sync is complete you’ll have interest on having a local_manifests. Basically on this local_manifests.xml , where some developers prefer to name it as roomservice.xml it is where you’ll add the changes to the manifest.xml or even sources which you wish to add to your building folder. This is a solution to you never edit the manifest.xml.
Usually it is added on the local_manifests the folders related to your device tree. I’ll give in this example how to build for the OnePlus One (bacon).
A device tree consists on configurations where you set information related to your device. Example if is qualcom, usually is android_device_qcom_common (where is the general settings) together with android_device_oneplus_bacon (where are the specific settings). When I say settings, for you to understand is like compile with the folder hardware/qcom/display for the display. You should take some time to explore to understand what is in it.
So you’ll add your local_manifests.xml this way.
Code:
[B]
mkdir .repo/local_manifests
nano .repo/local_manifests/local_manifests.xm[/B]l
You now add:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="CyanogenMod/android_device_oneplus_bacon" path="device/oneplus/bacon" remote="github" revision="cm-13.0" />
<project name="CyanogenMod/android_device_oppo_common" revision="cm-13.0" remote="github" path="device/oppo/common"/>
<project name="CyanogenMod/android_device_qcom_common" path="device/qcom/common" remote="github" revision="cm-13.0" />
<project name="CyanogenMod/android_kernel_oneplus_msm8974" path="kernel/oneplus/msm8974" remote="github" revision="cm-13.0" />
<project name="TheMuppets/proprietary_vendor_oneplus" path="vendor/oneplus" remote="github" revision="cm-13.0" />
</manifest>
Now you need to run the repo sync command again.
This has to do separately the first time or it won’t sync all the files you need. In case the repo sync fails with an error saying you need to do –force-sync just run repo sync –force-sync (this happens only when you change common git sources with your manifest.
After the sync is done you are ready to build!
To start building you’ll need to run the .envsetup.sh , which will load all the source code into memory. After that breakfast bacon userdebug (in case it is for the OnePlus One device), then later make bacon (the word bacon it is to be used on all devices , here it is just a coincidence with OnePlus One)
Code:
[B]. build/envsetup.sh
breakfast bacon
make bacon[/B]
After it compiled your rom will be located at /cm/out/target/product/bacon/
Easy until here? I hope so.
Possible errors :
Q: Receive error: fatal: duplicate path xxx/xxx in ~/cm/.repo/manifest.xml
A: edit .repo/local_manifests/local_manifests.xml to remove the item which matches the item located in bold.
Q: How big is the repo?
A: 50GB just source code and around 10GB when built per device. Therefore you should aim to have about 60GB free on your system.
The tools of development
Git
Probably many of you question about what it is git, read about it on the github manuals etc and still cannot figure out how to work (I took two weeks to understand that it is really simple). So imagine that you have a diary, but instead of being separated by dates it is separated by titles, which we call commits. And what is a commit? Basically it is a portion of code. So when you make a change and want to record that change, you create a commit and in the end it’ll be a portion of code. This portion of code, known as commit, can be easily ported between different sources.
Here is an example:
https://github.com/jgcaaprom/androi...mmit/9f16b3cd79ad7bb8c821a518ca73725f19c38478
The commit number is: 9f16b3cd79ad7bb8c821a518ca73725f19c38478
This commit has recorded a change of IZAT_DEBUG_LEVEL = 2 .
Now how to bring other commits from different sources into our source.
The process comes in 3 phases:
First we’ll have to add the source where the commits that interests us are with git add source_name link
Second we’ll download that source by using git fetch source command
Thirdly we’ll cherry-pick (bring the portion of code recorded in the commit) into our source in order to make the changes automatically.
So lets see a real scenario. Imagin you are interested on cherry-picking this source:
https://github.com/CyanogenMod/android_device_oneplus_bacon
What you’ll have to do is.
Step one: git add cm https://github.com/CyanogenMod/android_device_oneplus_bacon.git
Step two: git fetch cm
Step three: (imagine this is the commit you want:
https://github.com/CyanogenMod/andr...mmit/58027fcbea4dd9fbb5aaeb8ae5f6e32bdf613573 )
The commit number is: 58027fcbea4dd9fbb5aaeb8ae5f6e32bdf613573
So you’ll git cherry-pick 58027fcbea4dd9fbb5aaeb8ae5f6e32bdf613573
And voila! You’ve done your cherry-pick . Now it is important to have in mind how the cherry-pick process works which I’ll explain on the next step.
Cherry-picking
Cherry-picking is a process of importing code from one source to another. So the process that git does basically is, compares your present files in the source with the files that was on the source you are cherry-picking and if everything is a match it’ll change the code automatically for you.
Now lets pick up the example above and imagine that the changes you are doing instead of being exactly the same as described here:
https://github.com/CyanogenMod/andr...mmit/58027fcbea4dd9fbb5aaeb8ae5f6e32bdf613573
Your source has a difference which doesn’t have this line:
32 private static String CONTROL_PATH = "/proc/touchpanel/keypad_enable";
You’ll notice that it’ll give a conflict. The reason for that is because the git when comparing understood that there was no match between the sources. When that happens means basically that there might be changes you should do in order for the code to be compatible, so you’ll have to review that code.
Now the review process is very simple. For you to see which files are in conflict you’ll have to run git status ( basically this command informs you of the situation of the commits which are being cherry-picked and the changes which you’ve done. )
You’ll notice that the files which need to be edited/review are in red. In case it appears files in green, means that there was a perfect match and doesn’t need a review.
Pretty useful right?
After you finish editing all the code you’ll do git add . and for this exercise do git status again just for you to see what happened . Everything is green. To finish the cherry-pick you’ll now do git commit and done!
How to record my own changes and create a commit with it.
Basically this process is exatly the same as the previous one, the only difference is that after you made the changes, you can make git status, then git add filename in case you want to commit only one file or git add . in case you wish to commit all the files and to record the commit you write git commit, or git commit –m “commit message”.
Congratulations! You’ve just recorded your commit!
Git push/pull
There will be moments where we just wish that we could be lazy and cherry-pick everything all at once. Well there are some scenarios where you can actually do that, but remember it is not perfect. Lets imagine we are using the source above, and CyanogenMod uploaded like 20 different commits, your source is not exactly like CM source but you wish to keep your changes and also have all changes from CM what to do?
1) You can cherry-pick one on one. And waste a lot of time…
2) You can make a new source based on cm and include your changes there
3) You can git pull
Git pull basically will update your source with CM source by merging all the commits. You do that with:
git pull cm cm-13.0 (in case your rom is Marshmallow)
The git pull should only be used when the sources are very similar and you are using as a base. Basically it’ll warn you that’ll merge the code and voila done! 20 commits added to the source.
Now when on the situation that the sources are slight different or very different it’ll create a conflict. Again the git will do comparisons between the entire sources, check which commits are missing, compare the files just like with cherry-picking. And when you do git status, it’ll appear on red all files where you need to review your code.
After you finish, same as before
Code:
[B]git add .
git commit[/B]
Done.
I hope you are understanding everything until here.
git reset HEAD~n
This command is rarely used but is super usefull. Basically you are saying to git that you with to remove n commits you've reated/cherry-picked. For you guys to understand how it works, basically imagin you have just written/cherry-picked 10 commits, and you do git reset HEAD~3 , he'll basically remove from records 3 commits. But... That doesn't mean he reverted the code! In case you wish reset the code you need to do git reset --hard.
Also it is very usefull to help rewrite the history. Lets think the example I given before. When you do a git reset HEAD~3 , basically on a history of A B C D E F G H I J commits, the git will remove only the recorded commits H I J. If you do after a git status, you'll understand that the code is still there, which means the changes you done on H I J will still be there. So you can create a new commit with H I J all together . Simple!
Another way to create a unique commit with H I J is by using git rebase -i HEAD~3 , where you basically are instructing the git that you wish to rebase the source with an interactive selection. You'll see that it'll appear a commit list where you can remove other commits from history. But since you wish to create a unique commit you'll wish to change the instruction from pick with the letter s (without capslock term for squash) . Example:
Code:
[B]pick d0c49f4 UsbDeviceManager: Remove charging from persisted function composition
s 2c755a6 SystemUI: fix NFC tile sometimes hiding
s e39d1d7 Revert "base: start nfc service prior to systemui"
pick 9164274 DocumentsUI : Hide advanced menu option when in forced mode
pick 5f8d3f8 Themes: Expose Power Dialogs
pick 9153396 SysUI: Don't let rogue themes ruin notifications
pick 226797c Revert "Only show keyguard panel if on lockscreen + no activity on top"
pick e843aaf Fix NPE in DocumentsUI when rotate UI before format as internal
pick 26079d3 SystemUI: detect rotation and resize mKeyguardBlur accordingly
pick 80b060d Automatic translation import
pick 4282864 Automatic translation import
pick d442df6 wifi: Enable WiFi IpReachabilityMonitor by default
pick 9cf937f SystemUI: Add margin in qs_tile_top between instruction text and add button[/B]
Cool right?
And I believe I've covered with some examples the git. As you can see, once you get used to git you'll be able to use it easily.
Toolchains
There has been a big debate from many developers on which toolchains to use. Many prefer sabermod, others prefer uber, others google toolchain, etc. It is in fact debatable. If you ask me which one to use, I would say google or uber (very similer to google) and the gcc used by stock on the source. The reason is simple, the code is optimized for a certain gcc version, if you start using a gcc version which is not prepared to be used on the code, it won't translate correctly your instruction.
The source
When you start building roms, you should at least know a little about how the source of android is organized, what language it is used, etc. On android it is used C, C++, Java, Assembly. Withing the following folders inside the source it is used:
Java
Frameworks
Packages
external (some packages)
C++
ART
bionic
hardware
C
kernel
hardware
Assembly
bionic
some of the kernel libs
This is important for you to navigate easily within it. Some of you ask yourselfs what is one thing or another. I'll represent that to the following image which is published on the google developers page.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now I believe you wish to know which parts should be used in order to put a rom working for a certain device. Those parts are:
Hardware
Kernel
device tree
Vendor blobs
These parts are the "base" of your build to put a certain device in a working, since on these parts is where lies the instructions for the device to understand what to do.
The build folder is where you specify instructions of the building process. For example : Certain optimization, which GCC to use, where will the compiler find the apps to compile.
frameworks, system, packages and some of the folders within the external folder are the packages of what you will have inside the rom which is general and can be present on any rom.
external folder has present different things, compilers such as proguard, jemalloc. external software used by the rom such as sqlite.
prebuilts folder has present everything related to stuff which is already compiled, in this case clang, gcc toolchains.
I've done a very summarize version of the source in order for you to understand how that google built things, so I hope it is simple to understand these basics.

Another great contribution bro. Thanks for your work and for your help. Starting read right now
Edit: Amazing guide
Just one request, please bold when you write a command. I think it becomes more eligible.

@jgcaap I think this is useful
For those already have JDK8 installed, they can use it by adding this code to $HOME/.bashrc
Code:
EXPERIMENTAL_USE_JAVA8=true
You just have to source ~/.bashrc before make bacon

There's nothing better than learning something from a professional who you know has done such a great work. Thanks a million!! @jgcaap

I'll speak about different custom GCC and also other compilers, but it'll be on another section. I'll continue writing this on wednesday (exam tomorow). I believe that my guide will help understand all the basics.
If I speak about that mode, I believe it'll give the idea that it is a feature of linux and it isn't. It is something you can change inside the source in many different ways.

This might sound a little stupid but which JDK version is recommended? 7 or 8? Seems like 7 cause you have to enable "Experimental Use" for 8.

Great guide! Can you, if you have time, also post a guide only focusing on kernel building?

The quotation marks surrounding cm-13.0 in first post are not the right ones. So you need to replace those quotation marks if you copied and pasted the code in your manifest. Just delete the quotation marks and type them again.

Debian Buster WSL2 Kernel / ROM Builder [replaces VM]

Okay I don't have enough time to update this whole description, no one volunteered to host the VM so now I only have a Debian Buster WSL2 (Windows 10 latest) build environment. You can make kernels and ROMs from it. It has a built in XFCE4 and all the features listed below. It will build kernels for you from source and place them in AnyKernel3 zip files ready for flashing in the ~/ directory. Build scripts are provided for Op8T 5G custom and GPUOC RadioActive Kernels from my GitHub (modded for performance + battery). You can use this guide and get full audio and a GUI and all you need to build.
Try out this build for Debian Buster for WSL2:
First you need to ensure you are on a recent build of Windows, go to windows Updates in settings and download the latest.
Next open a Powershell Command Prompt in Admin mode. Type:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform -NoRestart
Restart your PC, then get back into an Admin Powershell prompt and type:
wsl --set-default-version 2
Next you can download this tar.gz distribution, it's quite big (6GB zipped -> 14GB unzipped). Apparently you can import a tar.gz directly, so I changed it from a .zip file to .gz: https://mega.nz/file/DkARXIjD#hGu8TjxaA__YrRsfqfWJw9-2ViyyntyK5U8JdClor6A
Easily move WSL distributions between Windows 10 machines with import and export!
wsl --import <DistributionName> <InstallLocation> <Full path to .tar/.tar.gz FileName>
After import, you should type: login: user password: user (also the sudo password) change the Global Git settings to your own email and username.
Open the command line.
Set your username: git config --global user.name "FIRST_NAME LAST_NAME"
Set your email address: git config --global user.email "[email protected]"
Then if you want to set up SSH between your WSL2 instance and NoMachine, download NoMachine here for your host PC: https://www.nomachine.com/download/download&id=8 then follow the steps to generate an SSH key, which will be located at ~/.ssh.
ssh-keygen -m PEM -t rsa -b 4096
Use the directory default ~/.ssh/
Then copy this file: ~/.ssh/id_rsa.pub to ~/.nx/config/authorized.crt
In the NoMachine GUI, you should select Configuration, Use a key based authentication key which you provide, then provide the path to the private key \\wsl$\debian\home\user\.ssh\id_rsa and check the box Import the key to the connection file.
To get to the XFCE4 GUI, you should type login: user password: user, then run /.nomachine.sh
It will post the IPV6 address you need to enter into the configuration into NoMachine on Windows 10. It changes every time you open it (WSL2 problem).
Now you should be able to connect to the GUI and use all the dev tools built in. Or you can just use the command line if you're more comfortable there. You'll probably need to do some more Googling to get everything setup the way you like. There are 2 examples in this file for an Op8T RadioActive modded kernel from my GitHub repos with a ./Build-Clang12.sh script you can use to see how to build a kernel. It it fully automatic. It will generate the zip specified in that file in the ~/ directory which can be flashed to a device via EX Kernel Manager or FK Kernel Manager. Best of luck!

Great job mate. I hope this is the kick off and boost up kernel development on the MI9 ??

Now THAT is what XDA is all about.
I'd like to get in to this type of development but simply don't have the personal time right now.
Hope this helps boost community support a bit.
This must've taken some time. Hats off to you sir.

Thanks Dave - this is the absolute easiest way to build a kernel. Yes it took forever to get working, a lot had to do with bad Xiaomi source code and Android 9 package requirements for building kernels. You can simply download, install, click Goto Build, click on QClang8_Build, copy/paste it's text from Geany into the open terminal, sit back and wait for the build to finish. Then once it completes, you click on Built Kernels and you have your image ready. A few more steps obviously outlined in the post to transfer to the host machine (cp Image-dtb /media/sf_VMxfer) and pack via Android Image Kitchen, copy to the device, and flash via TWRP. Most features require Magisk patching as well to enable altering in a kernel manager. The mentioned repo (mrslezak) has Fsync toggle, 830GPU overclock, and F2FS file system support (Mauro TWRP has just enabled it, so I'm using it now). I should note as well that this kernel has only been tested on MIUI and Xiaomi.eu builds thus far (anything based on Xiaomi MIUI should work - MIUI Global Dev, China Dev, Xiaomi.eu, MiGlobe, RevolutionOS, etc. as long as it is Android Pie).
I'm waiting on others to jump on board!!!! Hopefully it happens

Excellent guide, will work for almost all pie devices!
Great work OP :highfive:

Hi, @mslezak @acervenky Can you help me to build kernel for Stock Miui 10 for K20/Mi9t . I followed your guide setup all requirement i just changed the device code name from cepheus to davinci everything went well kernel complied and also created the boot.img with AIK but after flash it is through back me to recovery.
Can you Please help me with this.

@acervenky fixed that by applying the patch in the Desktop Mi9_Build_Tools/Required_Patches_to_Compile_Xiaomi_Source/cosmin_kernel-module.c copy that to /kernel/module.c, he can chime in here. Or check out his repo he has one on Github that compiles already QUAX kernel I believe with a bunch of stuff added already over stock.

Good job. Compiled a kernel for mi9t pro (raphael) with your detailed guide.
Can you help with "make modules" command?
I need to make xt_HL.ko module, but it not compiling ((
Not needed anymore, made it successfully.

Can you compile q kernels with this?

New Q build VM coming soon. GCC10 x64 and Arter97 GCC9 x32 toolchain.
Just a notice here I have a VM almost ready to upload that can build Mi9 source. It's a ton of patches to stock code but I'll setup a repo with them already applied.

Can i use anykernel to make a flashable zip? Or do i have to use a diffrent approach?

https://mega.nz/#!voJEGIRC!r4FcV6zUlVbFExcidhL9JmgVZlu3IscYH-S5XlnTUJI Android Q VM - expands to 40gb on your hard drive so you don't run out of space. Builds a GCC10 patched version of Xiaomi Cepheus and Raphael kernels from my repo, forked from Xiaomi and commits outlining every step needed to get it to build. https://github.com/mrslezak/Cepheus-Raphael-Q-GCC10

Yes AnyKernel3 is the easiest

Sure AnyKernel3 is easy, take someone's kernel zip, insert your Image-gz.dtb or Image-dtb into the root of the zip, delete the other kernel, and you should be able to flash it.

got some compile errors today when i tried your wm
/home/user/toolchains/aarch64-linux-elf/bin/aarch64-linux-elf-ar: kernel/resource.o: No such file or directory

I'd first try a: make clean; and: make mrproper;....
But here's more info:
Double click the GoTo Build icon, a terminal will open in the source directory. Then in the terminal: cp /home/user/Desktop/Build GCC10 Cepheus.sh .; chmod +x "Build GCC10 Cepheus.sh"; ./"Build GCC10 Cepheus.sh"; Once done the kernel will be in /home/user/Cepheus-Raphael-Q-GCC10/out/arch/arm64/boot/Image.gz-dtb. /out9TP/ for Raphael, just substitute the build script you need.
If it then still won't build, you'll have to grab the repo again. Type: git pull
Or the safest is a complete re-download: cd ..; rm -rf Cepheus-Raphael-Q-GCC10; git clone --depth=1 https://github.com/mrslezak/Cepheus-Raphael-Q-GCC10.git and repeat the prior copying of the build script to the source directory.
I tested this last night and it worked. If I tried to just drag the script into a terminal window it failed. There could be some dirty files in there not sure how that happened, but deleting and cloning again definitely works. I built both Cepheus and Raphael kernels last night in the VM off a fresh clone of the repo. I'd update I but it literally takes 6hrs + since the files are huge and take forever to compress and upload to Mega. And I have to delete so much off my VM and SSD just to do it. This way you learn something too

I first drag n dropped the file when i got the error, then i remembered when i compiled kernels for my raspberry pi's it also failed if i draged n dropped my build script so i did it the proper way and it worked
Thanks for your WM it's working great

Yeah if you buy me Google drive space I'd be more than happy to upload to Google Drive. I'm out of space man. If you run Windows 10 Preview WSL2 I have a 3.2GB build that kills everything else out there.

[ROM][COMPILING][HELP]LMX210ULMA K8+ custom rom and kernel Q&A

I am in no way resposible for any negative effects to your device by trying any of this for yourself. Including bricking your device, divorce, nuclear meltdown, zombie apocalypse or any other malfeasance. Try at your own risk.
Hi guys
Im still a jr member here and learning but ive rooted a few phones and ported a twrp and now I want to build a custom kernel and ROM for my new phone the K8+ 2018 LMX210ULMA. I plan to do this all from the phone im building the ROM for using termux and Anlinux to install Ubuntu and all the proper build essentials. So lets get started!!!
First i have some questions and then ill note where i am in my project. Ive actually been working on this for a while using this and that thread but i have some questions i have never been able to find answers to. Like.......
1. Does the kernel source code need to be unpacked in the same folder as the device source code?
2. How can i build seperate modules like bootloader or recovery or anything else.
3. Is there a way for some one who has a locked network carrier device to build a kernel that is unlocked.
4. How do you find device, vendor and kernel trees for a device that hasnt been publicly built yet?
5. When installing dependency libraries to ubuntu what do i do when Ubuntu is unable to locate a package. For examle: lib32ncurses5-dev lib32z-dev and lib32esd1.0-dev
Ok now lets get to setting up the envrinonment or at least what i have so far.
A rooted phone is needed to get the job done as far as far as i know so you might want to work on that first. My particular phone variant doesnt seem to have a recovery option just yet due to some bit of hiding of hiding the fastboot mode but im hoping by compiling a custom ROM and Kernel i can alleviate that and help myself and all the other good folks that want to fully root thier phone and also learn to make thier own custom ROM.
So far im rooted using a temp root that utilizes an exploit called mtk-su. It gives basic root privilages and allowed me to make a couple changes to my build prop like adoptable storage and allow some changes here and there with out upsetting the system partition to much.
You will need adoptable storage storage for this to work as repo will need to unload ton of source code to your device so 32+ gigs of internal storage will be needed.
Im not going to go into the specifics of the two forementiined needs but a quick search should point you in the right direction and get you going.
1. Install termux and installed the basic packages in the welcome plus:
Code:
pkg install libandroid-support libandroid-support-static libandroid-shmem libandroid-shmem-static libusb libusb-static libccid
2. Install Anlinux and follow the instructions to build Ubuntu within the termux environment. Make sure to do it as root which is essential for this to work correctly.
3. Install a vnc viewer. I dont really use it. It would be nice to have a way to use a web browser with in it but so far no go.
4. Once you have Ubuntu built and started its time to install more dependecies. Yay!
Code:
apt-get install sudo
Code:
sudo apt-get install software-properties-common
Code:
sudo apt-get install bison build-essential curl ccache flex libncurses5-dev libsdl1.2-dev libxml2 libxml2-utils lzop pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev git-core make android-sdk gperf openjdk-8-jdk -y
So far i have been able to install all but 3 of the dependecies needed. Lib32ncurses5-dev lib32z1-dev and lib32esd0-dev any one knowing a work around or way to locate and install them please for the love of android speak up.
5. Now lets do some more setting up the build environment with repo. I have tp say repo is a pretty cool tool here but it has its problems. First the repo init command is sketchy and doesnt always work. I had a hard time with it at first. Second even though you tell it which manifest exactly you want to download it will download others as well and draw source code from every other build. This is a problem as it downloads every pre-built toolchain in the repisitory and almost every android repository in existance. They talk about the source code from repo taking up so much space well that is exactly why. Ive been compiling in C++ for years and i have never seen such a mess. But so be it. Maybe the android gods will straighten it out someday and make it easier and consume less space by only downloading the appropriate source code needed by your specific build.
This is the end of this post so i have to finish up on the next BRB

Ok im back. Hows going androids? I am not a robot! But a few of my friends might disagree with statement.
I left off and we were about to finish up the build environment and get repo started so lets do that and i will tell you about the first big snag in the project next to not being able to find those three dependency libraries stated above.
Here we go first we create a new bin folder just for compiling android in the HOME folder of your ubuntu operating system then we set its path, download the repo launcher and set up our scripts.
By the way i probably should have mentioned this earlier but i assume every body at this point has some command line experience and should know that you copy these comnands and paste them one at a time. Please do not copy a whole code block at one time and paste it to your terminal or your gonna have a bad time like when you pizza when you are supposed to french fry.

Code:
mkdir ~/bin
PATH=~/bin:$PATH
cd ~/bin
curl

i can't help you much but i hope you won't brick your device. it would be easier for Mediatek there you can always restore from SP Flash Tool. for Qualcomm your only chance is to put it into EDL mode/ Qualcomm HS-USB QDLoader 9008 Driver with test point and flash with QPST/ LGUP. I recommend to figure out how to unbrick before you start flashing lk
also maybe helpful this link for understanding boot chain
http://www.lieberbiber.de/2015/07/05/mediatek-details-little-kernel

Any body know why i when i try to finish my lil tutorial here i cant do any more code blocks?

it's a bug in forum. i can't even post ls -l

i don't know much about compiling but i would scan lk.bin for strings containing oem fastboot commands (if they still left somewhere), and then scan the whole source code for respective strings in order to find the required build tree

Um well the problem is that im not familiar with the source code components and there are soooooooo
many components and lil info and no common place so far but here to ask questions and where do i start my questions.
Like what is the bootloader source code called. I guess i could load it up in android studio and do a search of all strings that way.
Right now im trying to grasp why all of a sudden 3 lmx210 variants known to be easily bl unlockable are now not. Lg is pkaying dumb or thier drones arent equipped with the proper knowledge

idk download from opensource.lge.com and search for fastboot
Code:
grep -ir fastboot .
kernel-3.18/arch/arm/boot/compressed/sdhi-shmobile.c
kernel-3.18/arch/parisc/kernel/process.c
kernel-3.18/drivers/gpu/drm/i915/i915_params.c
kernel-3.18/drivers/gpu/drm/i915/intel_display.c

kernel-3.18/drivers/net/ethernet/broadcom/tg3.c
kernel-3.18/include/linux/mfd/si476x-platform.h
btw why don't you cross-compile on linux machine, this would be probably easier as it seems it is well documented.
if one can help you re-enable fastboot in lk then its member @xyz`

Ok i want to do an experimental kernel build for my Alcatel tetra to try some things i hope to implement into my lmx210 build.
Can someone help me figure out to add a few of these options...'
Overclocked cpu or adjustable clock speed
Devtmpfs so i can fastboot other phones
power enabled otg
Loop device
Also which android kernel source should i download. Upstream or experimental or what. I just know i need a 4.4 + kernel
Alexcs.... Its an experimental issue with compiling on phone to see if there is a way to configure the system to allow for every thing needed to be able to do so. I cant always get to my pc and dont always have the option to dual boot or ubuntu. Some folks may not have access at all or only enough time to flash thier phone.
In this case the person compiling could build thier rom on thier device then take it and flash it when they can get to a pc

Ok i need some help here. pleeeeeeeaaaassee
i have been trying to compile a kernel for the Aristo 2 LMX210MA for three days and im about to lose it. My steps this far....
install ubuntu 18 on aristo 2
mkdir -p ~/kernel
cd ~/kernel
copied kernel source from storage and tar xvzf'd it
read the read me file for instruction and to get the name of the prebuilt tool chain. downloaded the toolchain and copied it to the /kernel/msm-3.18/android folder in ubuntu fs and tar xvzf`d it there as per read me file. made a few tweaks to the defconfig file. i wanted to build a devtmpfs and have full fs control over otg devices.
now i run these commands from msm-3.18 folder.........
mkdir -p out
make ARCH=arm O=./out cv1_lao_com-perf_defconfig
every thing goes fine til i run the next command and then it says no such file or directory for the androideabi-gcc file that is clearly in the tool chain and in the right place. and yes i set my path right i yell at the compiler on my phone.
make ARCH=arm O=./out CROSS_COMPILE=$(pwd)/root/kernel/kernel/msm-3.18/android/arm-linux-androideabi-4.9/bin/arm-linux-androideabi- KERNEL_COMPRESSION_SUFFIX=gz -j4

hello is there any one there. Any one at all

Ok i have been trying to compile a rom for months and i cant seem to get any where. I get errors about a freaking gcc wrapper and i have followed the advice i have seen on comoiling rom threads but i still get the errors. Its either that or the toolchains are crap.
Also have a question about compiling lg source code. When all is said and over with will it finish up as a kdz file? Im thinking it has too since thats the only way to flash thier firmware because they are locking up possibilities to unlock the bootloader.

I managed to compile my first kernel tonight. i know the zimage is the one i pack into my spkit image folder but dont know which of the split images to repkace

Ok i think it would be the only one in split image that matches the file type of zimage. I repacked it and flashed it via fast boot but both the repacked and magisk-patched.img return to fastboot upon booting
I wonder what could have gone wrong. The only things i changed were the config_mausb otg hotplug abd devtmpfs
Something i learned from reading the .config file in the out directory after doing the defconfig is that unless you compile your kernel on a pc first and remove a config there is no way to build android or a kernel on your device. Which explains months of aggravation and wonder. Yea they prohibit it but you can change the value and then do as you please
