Guide To Build Sultanxda CM13

since i'm a flashaholic and a great fan of sultan's cm13, i'm trying my hands on android rom development and i thought the first step would be to learn how to compile a rom from source and the best choice was cm13 by sultan.
i'm using google's cloud platform for vm instance and using ubuntu 14.04.
i've used @akhilnarang script (link to his github:github.com/akhilnarang/scripts ) to setup the build environment and followed these commands to build the rom.
Code:
~$ repo init -u git://github.com/CyanogenMod/android.git -b stable/cm-13.0-ZNH2K
~$ mkdir .repo/local_manifests
~$ curl https://raw.githubusercontent.com/sultanxda/android/master/bacon/cm-13.0-stable/local_manifest.xml > .repo/local_manifests/local_manifest.xml
~$ repo sync -c -j10
~$ ./patcher/patcher.sh
~$ make clobber
~$ . build/envsetup.sh
~$ lunch cm_bacon-user
~$ time mka bacon -j8
but after 1h or so the compiler spilled these errors
Code:
Package OTA: /home/arjunmanoj1995/out/target/product/bacon/cm_bacon-ota-f59d4b6456.zip
Traceback (most recent call last):

make: Leaving directory `/home/arjunmanoj1995'
#### make failed to build some targets (01:07:57 (hh:mm:ss)) ####
can someone plz help me resolve this error.

It seems like your missing the backports module to build certain parts of the rom. As i looked at the prepare script you used I noticed an commented piece of code in there refering exectly to your error regarding lzma backports:
Code:
#echo Cloning LZMA repo
#git clone https://github.com/peterjc/backports.lzma /tmp/backports.lzma
#cd /tmp/backports.lzma
#sudo python2 setup.py install
#python2 test/test_lzma.py
#rm -rf /tmp/backports.lzma
#echo LZMA compression for ROMs enabled
#echo "WITH_LZMA_OTA=true" >> ~/.bashrc
Running this, or running the prepare script again with this uncommented might acctualy fix your import problem

thanks mate, i'll give this a try and report back
edit: thanks .... it worked...:good:

I can't install the backports thing... I can't use the script to setup the build environment. How did you do it @baconxda? I uncommented those lines and it says that it doesn't have the lzma.h thing.

just run the script then run those commands quoted above, thats it.

@baconxda Any idea if this ROM could be built for any other device?

Supercharging your Github workflow with hub

Github being the world's biggest code hosting platform is also an OSS powerhouse. Their most under popularised creation is hub.
According to the official website, "hub helps you win at git". I'll be covering the installation and use below, and we shall see if we win or not
Installation
Installation is clean and easy. Download the latest release from https://github.com/github/hub/releases and unzip the archive. You should see the following files
Code:
.:
bin etc install LICENSE README.md share
./bin:
hub
./etc:
hub.bash_completion.sh hub.zsh_completion README.md
./share:
man
./share/man:
man1
./share/man/man1:
hub.1
Executing a simple ./install will install the hub binary, the man pages, and the hub+git bash completion script. You need to do one additional step before you're ready to use hub. Add alias git=hub to your .bashrc and then save it. Now every new terminal is ready to use hub, by using our good old git invocation.
Before adding the alias :
Code:
[email protected]:~$ git
usage: git [--version] [--help] [-C <path>] [-c name=value]
[--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
[-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
[--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
<command> [<args>]
These are common Git commands used in various situations:
start a working area (see also: git help tutorial)
clone Clone a repository into a new directory
init Create an empty Git repository or reinitialize an existing one
work on the current change (see also: git help everyday)
add Add file contents to the index
mv Move or rename a file, a directory, or a symlink
reset Reset current HEAD to the specified state
rm Remove files from the working tree and from the index
examine the history and state (see also: git help revisions)
bisect Use binary search to find the commit that introduced a bug
grep Print lines matching a pattern
log Show commit logs
show Show various types of objects
status Show the working tree status
grow, mark and tweak your common history
branch List, create, or delete branches
checkout Switch branches or restore working tree files
commit Record changes to the repository
diff Show changes between commits, commit and working tree, etc
merge Join two or more development histories together
rebase Forward-port local commits to the updated upstream head
tag Create, list, delete or verify a tag object signed with GPG
collaborate (see also: git help workflows)
fetch Download objects and refs from another repository
pull Fetch from and integrate with another repository or a local branch
push Update remote refs along with associated objects
'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.
After adding the alias:
Code:
[email protected]:~$ git
usage: git [--version] [--help] [-C <path>] [-c name=value]
[--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]
[-p | --paginate | --no-pager] [--no-replace-objects] [--bare]
[--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]
<command> [<args>]
These are common Git commands used in various situations:
start a working area (see also: git help tutorial)
clone Clone a repository into a new directory
init Create an empty Git repository or reinitialize an existing one
work on the current change (see also: git help everyday)
add Add file contents to the index
mv Move or rename a file, a directory, or a symlink
reset Reset current HEAD to the specified state
rm Remove files from the working tree and from the index
examine the history and state (see also: git help revisions)
bisect Use binary search to find the commit that introduced a bug

push Update remote refs along with associated objects
'git help -a' and 'git help -g' list available subcommands and some
concept guides. See 'git help <command>' or 'git help <concept>'
to read about a specific subcommand or concept.
These GitHub commands are provided by hub:
pull-request Open a pull request on GitHub
fork Make a fork of a remote repository on GitHub and add as remote
create Create this repository on GitHub and add GitHub as origin
browse Open a GitHub page in the default browser
compare Open a compare page on GitHub
release List or create releases (beta)
issue List or create issues (beta)
ci-status Show the CI status of a commit
You will see the second code snippet has some additional commands listed. We'll be going over all of these shortly.
Functionality
hub lets you simplify your clone commands. To clone your own repos, just specify the repo name, as in git clone local_manifests
Code:
[email protected]:~$ git clone local_manifests
Cloning into 'local_manifests'...
remote: Counting objects: 69, done.
remote: Total 69 (delta 0), reused 0 (delta 0), pack-reused 69
Receiving objects: 100% (69/69), 8.55 KiB | 0 bytes/s, done.
Resolving deltas: 100% (23/23), done.
Checking connectivity... done.
[email protected]:~$ cd local_manifests/
[email protected]:~/local_manifests$ git remote -v
origin [email protected]:MSF-Jarvis/local_manifests.git (fetch)
origin [email protected]:MSF-Jarvis/local_manifests.git (push)
To clone someone else's repo, just add the username to it
Code:
[email protected]:~$ git clone regalstreak/skadoosh
Cloning into 'skadoosh'...
remote: Counting objects: 176, done.
remote: Compressing objects: 100% (23/23), done.
remote: Total 176 (delta 10), reused 0 (delta 0), pack-reused 153
Receiving objects: 100% (176/176), 27.75 KiB | 0 bytes/s, done.
Resolving deltas: 100% (67/67), done.
Checking connectivity... done.
[email protected]:~$ cd skadoosh/
[email protected]:~/skadoosh$ git remote -v
origin [email protected]:regalstreak/skadoosh.git (fetch)
origin [email protected]:regalstreak/skadoosh.git (push)
All standard switches are supported as well, so you can pass -b cm-13.0 with the clone command.
hub also makes forking a very easy task, simply type git fork in a cloned repository's folder
Code:
[email protected]:~/skadoosh$ git fork
Updating MSF-Jarvis
From ssh://github.com/regalstreak/skadoosh
* [new branch] lol2 -> MSF-Jarvis/lol2
* [new branch] lolita -> MSF-Jarvis/lolita
new remote: MSF-Jarvis
[email protected]:~/skadoosh$ git remote -v
MSF-Jarvis [email protected]:MSF-Jarvis/skadoosh.git (fetch)
MSF-Jarvis [email protected]:MSF-Jarvis/skadoosh.git (push)
origin [email protected]:regalstreak/skadoosh.git (fetch)
origin [email protected]:regalstreak/skadoosh.git (push)
git fork --no-remote will fork the repo but will not add a remote as it did in the earlier example.
Another powerful feature of hub is the ability to create Pull Requests from the terminal. Here you can see me adding a commit to @regalstreak's automated ROM source compression script
Code:
[email protected]:~/skadoosh$ nano compress.bash
[email protected]:~/skadoosh$ git status
On branch lolita
Your branch is up-to-date with 'origin/lolita'.
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: compress.bash
no changes added to commit (use "git add" and/or "git commit -a")
[email protected]:~/skadoosh$ git add -A
[email protected]:~/skadoosh$ git commit -asm "Exodus 6.0"
You need a passphrase to unlock the secret key for
user: "Harsh Shandilya (MSF Jarvis) <[email protected]>"
4096-bit RSA key, ID A950D459, created 2016-08-21

Delta compression using up to 4 threads.
Compressing objects: 100% (3/3), done.
Writing objects: 100% (3/3), 1014 bytes | 0 bytes/s, done.

remote: Resolving deltas: 100% (2/2), completed with 2 local objects.
To [email protected]:MSF-Jarvis/skadoosh.git
aeff4d3..6972288 lolita -> lolita
I pushed this commit to my fork of the repo (I could have pushed directly as well, I'm a contributor ). Now we'll see how to start a PR from MSF-Jarvis/skadoosh to regalstreak/skadoosh, from the terminal.
To start a PR, use the following command
Code:
[email protected]:~/skadoosh$ git pull-request -h MSF-Jarvis:lolita -b regalstreak:lolita
https://github.com/regalstreak/skadoosh/pull/33
This command brings up a PR message editor that behaves much like the commit message editor we see all the time. Fill in and hit enter
create lets you, umm, create a new github repository from the current local repository. create also accepts some flags, which you'll see below
Code:
[email protected]:~/hub-rocks$ git status
On branch master
nothing to commit, working directory clean
[email protected]:~/hub-rocks$ git create -p -d "Super secret stuff here" hub-rocks
Updating origin
created repository: MSF-Jarvis/hub-rocks
[email protected]:~/hub-rocks$ git push -u origin master
Counting objects: 3, done.
Writing objects: 100% (3/3), 897 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)
To [email protected]:MSF-Jarvis/hub-rocks.git
* [new branch] master -> master
Branch master set up to track remote branch master from origin.
the 'hub-rocks' at the end is the repository name, which defaults to the current directory name, and goes up the folder structure until a folder name is found that does not match the name of an existing repository.
The created repo
{
"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"
}
browse lets you visit specific pages of any repo
Code:
git browse MSF-Jarvis/android_device_google_seedmtk commits
will open the commits view of my device tree repo for seedmtk
Code:
git browse regalstreak/skadoosh pulls
will show the PRs on @regalstreak's skadoosh repo, and so on.
compare is a pretty straight-forward command, to show a webpage with the diff between two tags, commits, or branches or a permutation of both.
Code:
[email protected]:~/skadoosh$ git compare -u MSF-Jarvis lolita..lol2
will compare the lolita and lol2 branches on my fork of regalstreak/skadoosh
release lets you create a new release on your repository and also adds tags, and uploads assets.
Code:
[email protected]:~/git-repos/reg-api$ git release create -a app.py v1.0
Uploading assets (1/1)
https://github.com/MSF-Jarvis/reg-api/releases/tag/v1.0
Which results in
issue works in a similar way
Code:
[email protected]:~/git-repos/reg-api$ git issue create -m "No authorisation enforced on endpoints" -l BUG,Will\ be\ fixed,Enhancement
https://github.com/MSF-Jarvis/reg-api/issues/1
Result
ci-status will show the Travis-CI response code for the latest commit on the repo and may return one of, success, pending, failure. On repos where CI has not been enabled, this returns a 404.
This is just a minor introduction to the things hub can do for you. Play around, and you'll find some more hidden goodies

@MSF Jarvis Another useful and awesome thread. I will check it out when I get home .

Very cool. Also another convenient thing I started doing with Hub is being able to `git clone user/repo` rather than having to manually copy&paste link to the repo. I’m definitely gonna use this extensively.

How To Compile Rom From Source full guide step by step by Jai Sharma

How To Compile Rom From Source
We need following things to compile ROM from source
A Computer( Linux or Mac)
Java JDK
Some required Package for building Rom
Rules for Accessing USB devices
Choosing a Branch
Installing Java on the Machine
Here i am using Ubuntu(14.04 LTS) as a Linux machine but it should work for other Linux variant
Open a terminal and type following
sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
This command will remove other existing openjdk installation
2. Once java is uninstalled use following command for installing correct version of java
sudo apt-get update
sudo apt-get install openjdk-s8-jdk
Check java version by typing following command
java -version
2. Installing some required packages
Type following in terminal to install some required packages
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip
3. Downloading Repo Tool and setting PATH
mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Now open the bashrc file and so we can include the repo tool:
sudo nano ~/.bashrc
Add following in the end of the file
export PATH=~/bin:$PATH
Now we need to reload bash variables to include the new path:
source ~/.bashrc
4. Initializing a Repo client
Now we need to create a directory where our source code will be downloaded. I am creating a directory AOSP here
mkdir AOSP
cd AOSP
In the following command insert your name and email address
git config --global user.name "Your_Name"
git config --global user.email "Your_EMail"
Now care fully select your branch whether you are downloading aosp or Cyanogenmod
repo init -u https://android.googlesource.com/platform/manifest -b android-7.1.0_r7
type your desired branch name after the -b. This also applies to Cyanogenmod
5. Downloading source code
Now start downloading source code by typing following
repo sync
Note: this may take some time depending upon your internet speed and also please make sure you have enough storage
6. Configuring USB Access
type your username in following command and type enter
wget -S -O - http://source.android.com/source/51-android.rules | sed "s/<username>/$USER/" | sudo tee >/dev/null /etc/udev/rules.d/51-android.rules; sudo udevadm control --reload-rules
7. Now building Rom for your device
To build rom we need following
Device tree
Vendor tree
kernel
Finding device tree and Vendor Tree
To find your device tree search on Github or similar sources with your device code name. If you are lucky you will find it there and believe me it is the easiest way to build your rom rather than creating device tree and vendor tree from scratch
Your device tree will go on following location
device/device_manufacturer_name/device_codename
Same for vendor tree
vendor/device_manufacturer_name/device_codename
If you find device tree and vendor tree then how to download it
For device tree
git clone “Github url” -b (branch_tag) device/device_manufacturer_name/device_codename
2. For vendor tree
git clone “Github url” -b (branch_tag) vendor/device_manufacturer_name/device_codename
Note1: You may need to change some files if everything is not working or giving you some error in rom compiling. Look into output to find out error. You can use Google if you can't correct it
Note2: You may be not found your device tree and vendor tree then what to do?. You may need to create them. Please follow my guide
Creating Device tree and vendor tree from scratch
For creating device tree
http://azodik.com/how-to-create-device-tree-for-android-rom-building/
2. For creating Vendor tree
“Coming Soon”
Kernel
For kernel part if you are lucky than you can find your kernel source from Github or similar sources. If not you can use your prebuilt kernel Foolow this to extract your kernel http://azodik.com/how-to-create-device-tree-for-android-rom-building/
Kernel location
/kernel/device_manufacturer_name/device_codename
Downloading your kernel
Manually download it and extract to kernel location or use following command
git clone “Github url” kernel/device_manufacturer_name/device_codename
Note1: You can use your prebuilt kernel. To use your prebuilt kernel edit BoardConfig.mk file in your device tree.
Note2: If you created device tree from scratch following my guide. Use of prebuilt kernel set to default
How to build
Use following command for building your rom
Source build/envsetup.sh
lunch
Now select your device from menu
3. make or mka
I hope you found it usefull. Please follow my website for interesting guide. Please comment here if you face any error.
Thank You

Really a great guide bro!
Can you please post a rom porting guide? easy to understand and effective

Nice tutor.. But it looks need an enormous data usage to do that. If i wanna porting rom for example slim rom nougat to my device (kenzo) can you give me some info how many data should i provide and how to do that? Thanks

thanks

sudo apt-get install openjdk-s8-jdk
Check java version by typing following command
java -version
2. Installing some required packages
Type following in terminal to install some required packages
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \
lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \
libgl1-mesa-dev libxml2-utils xsltproc unzip
3. Downloading Repo Tool and setting PATH
mkdir ~/bin
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Now open the bashrc file and so we can include the repo tool:
sudo nano ~/.bashrc
Add following in the end of the file
export PATH=~/bin:$PATH
Now we need to reload bash variables to include the new path:
source ~/.bashrc
4. Initializing a Repo client
Now we need to create a directory where our source code will be downloaded. I am creating a directory AOSP here
mkdir AOSP
cd AOSP
In the following command insert your name and email address
git config --global user.name "Your_Name"
git config --global user.email "Your_EMail"
Now care fully select your branch whether you are downloading aosp or Cyanogenmod
repo init -u https://android.googlesource.com/platform/manifest -b android-7.1.0_r7
type your desired branch name after the -b. This also applies to Cyanogenmod
5. Downloading source code
Now start downloading source code by typing following
repo sync
Note: this may take some time depending upon your internet speed and also please make sure you have enough storage
6. Configuring USB Access
type your username in following command and type enter
wget -S -O - http://source.android.com/source/51-android.rules | sed "s/<username>/$USER/" | sudo tee >/dev/null /etc/udev/rules.d/51-android.rules; sudo udevadm control --reload-rules
7. Now building Rom for your device
To build rom we need following
Device tree
Vendor tree
kernel
Finding device tree and Vendor Tree
To find your device tree search on Github or similar sources with your device code name. If you are lucky you will find it there and believe me it is the easiest way to build your rom rather than creating device tree and vendor tree from scratch
Your device tree will go on following location
device/device_manufacturer_name/device_codename
Same for vendor tree
vendor/device_manufacturer_name/device_codename
If you find device tree and vendor tree then how to download it
For device tree
git clone “Github url” -b (branch_tag) device/device_manufacturer_name/device_codename
2. For vendor tree
git clone “Github url” -b (branch_tag) vendor/device_manufacturer_name/device_codename
Note1: You may need to change some files if everything is not working or giving you some error in rom compiling. Look into output to find out error. You can use Google if you can't correct it
Note2: You may be not found your device tree and vendor tree then what to do?. You may need to create them. Please follow my guide
Creating Device tree and vendor tree from scratch
For creating device tree
http://azodik.com/how-to-create-device-tree-for-android-rom-building/
2. For creating Vendor tree
“Coming Soon”
Kernel
For kernel part if you are lucky than you can find your kernel source from Github or similar sources. If not you can use your prebuilt kernel Foolow this to extract your kernel http://azodik.com/how-to-create-device-tree-for-android-rom-building/
Kernel location
/kernel/device_manufacturer_name/device_codename
Downloading your kernel
Manually download it and extract to kernel location or use following command
git clone “Github url” kernel/device_manufacturer_name/device_codename
Note1: You can use your prebuilt kernel. To use your prebuilt kernel edit BoardConfig.mk file in your device tree.
Note2: If you created device tree from scratch following my guide. Use of prebuilt kernel set to default
How to build
Use following command for building your rom
Source build/envsetup.sh
lunch
Now select your device from menu
3. make or mka
I hope you found it usefull. Please follow my website for interesting guide. Please comment here if you face any error.
Thank You

Building AOSP Emulator

Though it's not necessary to build AOSP to build AOSP emulator, but I will discuss it here anyway.
Note: From here on we are considering, $HOME/AOSP is our AOSP repo download folder.
Android Build:
-----------------
Everything are already explained in source.andorid clearly except some step. I am going to explain those.
1. Follow this url, "https://source.android.com/setup/build/requirements".
2. Replace branch name of,
repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1
by going "https://android.googlesource.com/platform/manifest" and select chosen branch. Download may take up to 20 hours or more.
3. If not sure what argument to choose from lunch command, just type lunch and a bunch of options will be shown. Then select the correct one.
4. Replace "make –jN" to the number of threads you have in your PC. For example for a 4 thread processor "make –j4" will be the command.
5. If jack server has any memory issue run following command,
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server
Remember to replace –Xmx4g accordingly, here 4g means 4GB. Total build may take up to 9hrs.
6. After that, for every incremental build, type source and lunch command then make command for fresh started terminal otherwise only make will do.
Adding Default Application to android Source:
--------------------------------------------------------
1. Create an application in Android Studio.
2. We don’t need any gradle related folders for AOSP build. Take only java, assets and res folder and copy that in a new folder. Then take that folder to "AOSP/packages/apps" folder.
3. Add "Android.mk" file to that folder and add following lines (replace AppName accordingly and if app has assets un-comment line starting with "LOCAL_ASSETS_DIR"),
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_PACKAGE_NAME := AppName
LOCAL_SDK_VERSION := current
LOCAL_SRC_FILES := $(call all-java-files-under, java)
# Include libraries
#LOCAL_JAVA_LIBRARIES := <Java lib dependencies>
LOCAL_STATIC_JAVA_LIBRARIES := android-common
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v4
LOCAL_STATIC_JAVA_LIBRARIES += android-support-v7-appcompat
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/res
#LOCAL_ASSETS_DIR := $(LOCAL_PATH)/assets
LOCAL_AAPT_FLAGS := --auto-add-overlay
LOCAL_AAPT_FLAGS += --extra-packages android.support.v7.appcompat
include $(BUILD_PACKAGE)
4. Don't use newly introduced layouts, which may create run-time exception (use linear, relative or other old layouts). Also use properly scoped style. For example,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:id="@+id/textView"
android:layout_width="50dp"
android:layout_height="30dp"
android:layout_weight="1"
android:text="Hello World!"
android:textAppearance="@android:style/TextAppearance.Large" />
</LinearLayout>
In andorid studio "android:layout_width" may be written as "layout_width" and "@android:style/TextAppearance.Large" may be written as "TextAppearance.Large". We've to add full scope to every item, as AOSP build doesn't use gradle build system.
5. Add app name to "PRODUCT_PACKAGES" variable of "AOSP/build/target/product/core.mk" and "AOSP/device/generic/armv7-a-neon/mini_common.mk" files.
6. Build app using make appName then use make –jN or make snod.
NOTE: In emulator, settings page might crash. To fix this, go to "AOSP/packages/apps/Settings/src/com/android/settings/wfd/WifiDisplaySettgins.java", replace existing code by code below,
public static boolean isAvailable(Context context) {
return false;
//return context.getSystemService(Context.DISPLAY_SERVICE) != null
// && context.getSystemService(Context.WIFI_P2P_SERVICE) != null;
}
Emulator Build:
------------------
1. Android emulator is build upon QEMU. Branch for QEMU on "https://android.googlesource.com" is named qemu and generic kernel is in goldfish branch. Note that though we can build goldfish kernel using simple make commands, we've used prebuilt kernel for our approach.
2. Emulator source:
git clone https://android.googlesource.com/platform/external/qemu
(note there is another branch named qemu-android, this branch is not used any more so avoid cloning that branch)
Goldfish source:
git clone https://android.googlesource.com/device/generic/goldfish
(not needed to build emulator)
3. Remember we've to use the appropriate branch after repo name for example for emulator we are using latest 2.8 version which is in branch, "emu-2.8-release". So our command will be,
git clone https://android.googlesource.com/platform/external/qemu-android -b emu-2.8-release
or we can switch to that branch after cloning for master.
4. After cloning, copy the whole directory to "$HOME/AOSP/external" folder, rename older to qemu (if we've cloned qemu into our chosen named folder). We need this because qemu build uses "AOSP/external" and "AOSP/prebuilt" folder for its dependencies. By doing this we can avoid copying multiple repos for emulator, as we've already pulled it during AOSP cloning.
5. Run,
./android/configure.sh
./configure
6. We need to clone some other branches to build the emulator. Below branches should be copied to external folder,
git clone https://android.googlesource.com/platform/external/gtest -b emu-2.8-release
git clone https://android.googlesource.com/platform/external/tinyobjloader -b emu-2.8-release
put below branches in prebuilts/android-emulator-build folder,
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/archive -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/common -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/curl -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/mesa -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/mesa-deps -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/protobuf -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/qemu-android-deps -b emu-2.8-release
git clone https://android.googlesource.com/platform/prebuilts/android-emulator-build/qt -b emu-2.8-release
also we may need below branch, (we've to put it in "prebuilts/clang/host/linux-x86" folder)
git clone https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86 -b emu-2.8-release
Note: if we look through git path of each branch they are same as AOSP folder structure. So we can get the hint, where to put them
If any ssl problem occures to download repo, run below command,
export GIT_SSL_NO_VERIFY=1
7. Run "make -jN". if any other things are missing we will be shown the message and please clone those items from googlesource and put it in the correct location.
8. If emulator build failed for warning the run this "./configure --disable-werror", then make again.
9. After successful build we will get obs folder. Replace contents of "$home/AOSP/prebuilts/android-emulator/linux-x86_64" by the contents of our built folder.
10. Go back to AOSP root folder, now if we run "emulator" command, our custom built emulator will be used from now on.
11. We can run "emulator -verbose" to see generated commands.
Note: to buid AOSP again, we need to remove qemu, gtest, tinyobjloader from AOSP source, as they interfere with AOSP prebuilt packages. So after buiding emulator remove those folders from AOSP source folder.
Some Commands:
----------------------
This commands may or may not be needed, depending on the status of Ubuntu or source code.
1. Adding qt library in path
export PATH=/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64:/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64/gles_swiftshader:/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64/gles_angle:/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64/gles_angle9:/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64/gles_angle11:/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64/libstdc++:/home/saikat/AOSP/prebuilts/android-emulator/linux-x86_64/lib64/qt/lib:$PATH

Why the emulator repo isn't updates since 6 years ago? Where is the emulator app right now?

Git fails on merging security updates 04/2022 (ArrowOS-11.0)

Hey,
I've downloaded the merge-push.sh from https://github.com/ArrowOS/arrow_scripts/blob/arrow/merge-push.sh and am now trying to update my local source (Android-11.0) with the latest Android-11 security updates (https://android.googlesource.com/platform, Branch android-security-11.0.0_r54).
This fails with Git error "fatal: refusing to merge unrelated histories".
My understanding of this error is, that the ArrowOS-Android-11 source (into which I want to merge) is unrelated to the AOSP-Android-11 source (from which I'm trying to receive the updates). If so, I cannot understand this problem, since the ArrowOS code should be a fork or something, such that it originates from the AOSP-Android-11 source.
I've also checked after the failed merge, changes of security update April 2022 have not been incorporated into the ArrowOS code - makes sense, Git failed.
Commands issued:
1. cd WORKING_DIR (in my case /mnt/arrowos/repo_orig)
2. deleting existing code in local copy, e.g. rm -rf packages/apps/Launcher3
3. python3 repo sync -c --force-sync --no-clone-bundle --no-tags -j12
4. git pull https://android.googlesource.com/platform/art android-security-11.0.0_r54

Thanks a lot.

Hey there,
alright, I resolved this by checking out the entire repo, not just the part provided by
python3 repo sync -c --force-sync --no-clone-bundle --no-tags -j12
which does not clone everything.
Afterwards, merge worked smoothless - except for the merge conflicts, of course.
