[REF][DEV]Terminal Emulator Commands

Always wondered what the terminal emulator app does? Dont now what commands to type? Well this thread is all about that
ALERT!!! ALERT!!
BELOW ARE THE COMMANDS AND THE PROCESSES THAT WILL HAPPEN BY TYPING THE COMMANDS!!!
IF YOU DO NOT UNDERSTAND SOMETHING PLEASE SO NOT TRY IT.. IT IS RISKY AND WILL POTENTIALLY HARM YOUR DEVICE!!
DO NOT BLAME ME THEN!!
THIS IS A REFERENCE AND DEV THREAD. NOOBS SHOULD NOT LINGER AROUND HERE
The Android Shell
A "shell" is a program that listens to keyboard input from a user and performs actions as directed by the user. Android devices come with a simple shell program. This shell program is mostly undocumented. Since many people are curious about it I thought I'd write up some documentation for it.
Currently this documentation is incomplete, sorry!

Common problems
The built-in shell has very limited error handling. When you type a command name incorrectly it will say "permission denied", even though the real problem is that it couldn't find the command:

Code:
$ dir
dir: permission denied <---- this is a misleading error message, should say 'dir: not found'
$ ls
... listing of current directory
The PATH variable
The Android shell will run any program it finds in its PATH. The PATH is a list of directories. You can find out what your shell's PATH is set to by using the built-in echo command:
Code:
$ echo $PATH
/data/local/bin:/sbin:/vendor/bin:/system/sbin:/system/bin:/system/xbin
Depending upon your shell, you may see a different result.
Built in Commands
Every shell has a few built-in commands. Some common built-in commands are:
echo -- prints text to stdout.
set -- sets shell variables
export -- makes shell variables available to command-line programs
cd -- change the current directory.
pwd -- print name of the current directory.
Commands
To find out what commands you have available to you, use the "ls" command on each of the directories in the PATH variable.

Finding documentation for the Android commands.
Many of the Android commands are based on standard Linux (or bsd) commands. If you're curious about a command, you can sometimes learn how it works by using the "man" command on a desktop Linux or OSX (Apple Macintosh) computer. The Linux or OSX version of the command may be different in details, but much of the documentation will still apply to the Android version of the command.
Another source of documentation for people without a Linux or OSX machine handy is to use a web browser and use a web search engine to search for the text: "man Linux command-name".
List of commands
The following is a list of the commands that are present on a Nexus S phone running an Android 2.3.3 "user-debug" build. Many of these commands are not present on a "user" phone. (They are missing from a "user" phone because they are specific to developing or debugging the Android operating system.)
Code:
$ ls /data/local/bin
/data/local/bin: No such file or directory
Notice that by default there is no /data/local/bin directory. You can create this directory using the "mkdir" command if you like.
Code:
$ ls /sbin
opendir failed, Permission denied
The /sbin directory exists, but you don't have permission to access it. You need root access. If you have a developer phone, or otherwise have root access to your phone you can see what's in this directory.
Code:
$ su
# ls /sbin
ueventd
adbd
# exit
$
Notice that the shell prompt changes from a '$' to a '#' to indicate that you have root access.
Click to expand...
Click to collapse
Notice also that neither of the /sbin commands are useful to the shell -- the adb and ueventd files are 'daemon' programs used to implement the Android Debugger "adb" program that is used by developers.
Code:
$ ls /vendor/bin
gpsd
pvrsrvinit
Vendor/bin is where device vendors can put device-specific executables. These files are from a Nexus S.
Code:
$ ls /system/sbin
/system/sbin: No such file or directory
This directory does not exist on a Nexus S.
Code:
$ ls /system/bin

Versions of the Android Shell
Android 1.0 used a shell that had no tab completion or history editing.
Android 2.3 added history editing. You can for example use the up/down arrows to edit previous commands.
Other shells
Busybox
Busybox is a program that contains a shell and a set of command line utilities. Search Android Market for "Busybox" and you should find some versions you can install. The Busybox shell includes tab completion and history editing. Some versions of Busybox for Android do not require that you root your phone.
Debian utilities
You can install the full Debian shell and utilities. (Debian is a popular desktop Linux distribution.) I don't know the details, and it may require a "rooted" phone. Try a web search for "Debian Android install".
Custom ROMs
Some custom ROMs come with their own shells and utilities. If you are using a custom ROM, check its documentation to find out what's available.

How can I view stdout outputs in terminal emulator window?
For example with dd command, not specifying output should display it at current terminal, like in linux, but actually doesn't. Any ideas?

Hey wanna troll someone's phone
Type in terminal "stop" lololol

Similar to linux terminal commands I use
Nice work though, great guide, thanks dude
W!LßSO @ XDA

Great guide, but you have forgot a very useful command: grep
It allows to apply filters to the output of the commands. The syntax is:
Code:
command | grep filter
For example, to list only the apk files inside a folder:
Code:
ls /folder/to/list | grep .apk

Great guide!
IMO dmesg is also important. Maybe you should add in a description for it?
Dmesg --> prints the Linux kernel output, which is different from the Android system output, logcat. Useful for checking hardware and to see if modules started up succesfully. Also useful for debugging in conjunction with logcat.
Code:
cat /proc/kmsg > /sdcard/dmesg.txt
Copies the dmesg output to a file fled dmesg.txt on the sdcard
And
Code:
cat /dev/log/system > /sdcard/logcat.txt
Copies the logcat output to a file named logcat.txt on your sdcard.
Also, you missed out the parted and e2fsck commands, used for partitioning and checking filesystem integrity.
Also, the command free (display free ram/swap) is not included.

I am having SGS2 and yes it supports mass storage for internal sdcard...
When i connect to my computer it shows only internal sdcard and not external card which is present in the external sdcard slot...
actually the problem is that my sdcard gets detected some times and sometimes it doesnt...
i searched a lot and many of them told that it is a kernel version issue.. i updated kernel still no luck..
then i got one thread which gave me the solution of check disk so was thinking whether terminal emulator has any commands for check disk..

Hi hetunandu, great guide,
but still I don't understand few things:
1: how to run a specific action of an app?
2: how to KNOW the exact sintax of possible actions of an app?
3: is it possible to launch these commands via SSH (through an SSH server)?
eg: I want to start a audio-recording app on my phone from my computer, AND start recording from remote. Is it possible?
Thank you
(and sorry for my english..)

JFI - Never run fsck on a mounted partition.. You will corrupt your data!

Usually fsck won't run on that case and you warn you, you will have to use the force option in that case.

reading traffic stats
I am trying to get the traffic stat getMobileRxBytes (or any other traffic stat) to output a usable result in the terminal emulator. The goal is simply to be able to copy the rx bytes total to be used in Tasker. However, I can't seem to be able to get any output. I would appreciate it if anybody knows the proper command/syntax to show this traffic data. Thanks.
I am on a stock rooted 4.1.1 Galaxy Nexus.

[Q] Is there a command to show some configuration ?
I have run this command on terminal emulator:
[email protected]:/ $ su
[email protected]:/ #setprop net.cdma.rstp.proxy.addr 0.0.0.0;
[email protected]:/ #setprop net.cdma.rstp.proxy.port 0;
[email protected]:/ #setprop net.cdma.httppd.proxy.addr 0.0.0.0;
[email protected]:/ #setprop net.cdma.httppd.proxy.port 0;
Is above command right..???
after that i ran "getprop" i don't see effect of that command.
Can you tell me the right way or command to change my rstp & httppd setting...? cause my Epic4G cannot play video streaming after flashing CM10 nightly.
thanks,
adit

Hi... Before this I have rooted my phone since yesterday when I accidentally copy su file from "/system" to "/system/bin/" andnow I can't get root access because on Superuser I check the su version was 3.1.1 but there got red words maybe it try saying that I put su file in wrong location and I can't move it back because my root explorer can't get root access and it just show Root Explorer acess denied by Superuser. Terminal emulator also access denied. One more I'm using Sony Ericsson W8 and it can't unlock bootloader. Could someone help me to remove su file from "/system/bin". Thanks You

[TUTORIAL ] Beginning development-the easy way

Ok so this is a guide that me and my friend made for compiling ROMs for our LG-P350 Now, this is pretty much universal and can be used for general development
This is the stuff you will need :
Ubuntu-can be found on the Ubuntu website http://www.ubuntu.com/start-download?distro=desktop&bits=64&release=lts (this is a direct link to the Ubuntu 12.04 64-bit version)
Python (included)
GNU Make
Java Development Kit (JDK) 6
Git
Before you can do anything you need to install Ubuntu. You can go with newer versions but i still think that 10.10 is best and this guide is adapted to it. You can install it like dual boot or use Wubi (Windows Ubuntu Installer). However if you choose Wubi there is a good chance that you won't have enough storage, so that's not recommended.Those who want to dual-boot check out this post http://forum.xda-developers.com/showpost.php?p=34669858&postcount=26
NOTE: You can do this in a virtual machine (for example VM Ware and Virtual box) but it will be a lot slower unless you have a VERY strong CPU and a LOT of RAM.
Generally Python is not needed since it's already in Ubuntu. However if you want to install it separately here's how:
First of all open the terminal. Now copy/paste these codes (one by one) and execute them:
Code:
sudo apt-get install build-essential gcc
cd Downloads
wget http://www.python.org/ftp/python/2.5.6/Python-2.5.6.tgz
tar -xvzf Python-2.5.6.tgz
cd Python-2.5.6
./configure --prefix=/usr/local/python2.5
make
make test
sudo make install ([B]NOTE[/B]: [I]You will be asked for your password, enter it and press enter[/I])
sudo ln -s /usr/local/python2.5/bin/python /usr/bin/python2.5
Now you need Sun JDK 6. Same procedure as with Python:
Code:
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jdk
For those who get package error try these:
Code:
sudo add-apt-repository ppa:sun-java-community-team/sun-java6
sudo apt-get update
sudo apt-get install sun-java6-jdk
sudo update-java-alternatives -s java6-jdk
Now that JDK is installed it's time for GNU Make:
First of all download GNU Make from link given. Download version 3.82
Now extract the downloaded file to your Home directory.
Go to Home directory and change the name of GNU Make To make
Now open the Terminal and type the following codes
Link: http://ftp.gnu.org/gnu/make/
Code:
cd make
./configure
sudo make install
Now make is installed.
Next, we are going to install the dependencies:
FOR UBUNTU 10.10
Codes to type in terminal :
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential \ zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs \ x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev \ libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown \ libxml2-utils xsltproc
export USE_CCACHE=1
If that method didn't work then try this:
You use the same commands BUT the first one is:
sudo apt-get install git-core gnupg flex bison gperf build-essential
Now it should download some stuff. When its done you need to do the same for the rest in the right order.
NOTE: Since I don't remember the right order i will just put the commands how they should be written if you get error read what's missing and put that in first.
Here are the rest of the lines:
Code:
sudo apt-get install zip curl
sudo apt-get install zlib1g-dev
sudo apt-get install libc6-dev
sudo apt-get install lib32ncurses5-dev
sudo apt-get install ia32-libs
sudo apt-get install x11proto-core-dev
sudo apt-get install libx11-dev
sudo apt-get install lib32readline5-dev
sudo apt-get install lib32z-dev
sudo apt-get install libgl1-mesa-dev g++-multilib
sudo apt-get install mingw32
sudo apt-get install tofrodos python-markdown
sudo apt-get install libxml2-utils
sudo apt-get install xsltproc
FOR UBUNTU 12.04
Code:
sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
libgl1-mesa-dev g++-multilib mingw32 openjdk-6-jdk tofrodos \
python-markdown libxml2-utils xsltproc zlib1g-dev:i386
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
Now for the Android SDK, ADB and ADB path:
1. SDK (Software-Development-Kit) :
Go to this link and download the Android SDK for Linux:
http://developer.android.com/sdk/index.html
After downloading it, extract it to the Home folder. You can probably extract where you want and change all the steps below to to fit your set up, but I like putting it in Home folder.
When you have extracted it in the Home folder change the name of the folder of android-sdk-linux to sdk.
Then open the Terminal and run these codes:
Code:
cd ~/sdk/tools/
./android sdk
When you run this, a window will pop up. For this you only need "Android SDK Tools" and "Android SDK Platform-tools". Just check these two and install them.
2. ADB (Android-Debug-Bridge):
Run this command to see if your ADB works. You have to have your android device connected in debugging mode.
Run these codes in the Terminal :
Code:
cd ~/sdk/platform-tools ./adb devices
When you entered the codes above, you should see something similar to this:
List of devices attached 0123456789ABCDEF device
NOTE: If you see output like given bellow we need to give the device permissions. Don't worry I had this too when I set my computer up for the first time.
List of devices attached ???????????? no permissions
Here is how we fix it:
Open the Terminal and type this:
Code:
gksudo gedit /etc/udev/rules.d/51-android.rules
After you've entered it, a window will pop up that will be blank. Now add the following commands and save it.
Code:
SUBSYSTEM=="usb", ATTRS{idVendor}=="1004", MODE="0666"
Now save this File And follow the given codes
After you've entered those codes type these codes in too.
Code:
sudo service udev restart
sudo adb kill-server
sudo adb start-server
After you've entered those codes, restart Ubuntu.
Now to see if the problem is solved type these codes in:
Code:
cd ~/sdk/platform-tools ./adb devices
If everything is ok a output similar to this will be shown:
List of devices attached 0123456789ABCDEF device
Now to add the ADB path to system, so you don't have to cd to the SDK folder every time you want to use ADB:
So, first open up .bashrc with these codes:
Code:
sudo gedit ~/.bashrc
A window will pop up and there will be some text there. Scroll down to the bottom and add these lines:
Code:
export PATH=${PATH}:~/sdk/tools
export PATH=${PATH}:~/sdk/platform-tools
After you've done that, save it and reboot Ubuntu.
If everything is ok, you will get some output when you type the following codes in the terminal.
Code:
./adb devices
OR
Code:
adb shell
If you see:
Code:
adb not found[CODE]
Then it means you've done something wrong and ADB is not configured.
Next is GIT:
Open the browser and download git from given link
[URL]http://git-core.googlecode.com/files/git-1.7.9.6.tar.gz[/URL]
Extract GIT-1.7.9.6.tar.gz to your home directory
Rename the folder you extracted to from GIT-1.7.9.6.tar.gz to git
After you've done that, enter the following codes in the Terminal
[CODE]sudo aptitude build-dep git-core
sudo apt-get install zlib1g-dev
cd git
./configure
make
sudo make install
NOTE: If it doesn't work then install from this link:
http://kibyegon.wordpress.com/2010/0...u-lucid-10-04/
If the commands from above are not working then try this:
Code:
sudo apt-get install git-core
sudo apt-get install git
git
If it worked it should show this:
Code:
usage: git [--version] [--exec-path[=GIT_EXEC_PATH]] [--html-path]
[-p|--paginate|--no-pager] [--no-replace-objects]
[--bare] [--git-dir=GIT_DIR] [--work-tree=GIT_WORK_TREE]
[--help] COMMAND [ARGS]
The most commonly used git commands are:
add Add file contents to the index
bisect Find by binary search the change that introduced a bug
branch List, create, or delete branches
checkout Checkout a branch or paths to the working tree
clone Clone a repository into a new directory
commit Record changes to the repository
diff Show changes between commits, commit and working tree, etc
fetch Download objects and refs from another repository
grep Print lines matching a pattern
init Create an empty git repository or reinitialize an existing one
log Show commit logs
merge Join two or more development histories together
mv Move or rename a file, a directory, or a symlink
pull Fetch from and merge with another repository or a local branch
push Update remote refs along with associated objects
rebase Forward-port local commits to the updated upstream head
reset Reset current HEAD to the specified state
rm Remove files from the working tree and from the index
show Show various types of objects
status Show the working tree status
tag Create, list, delete or verify a tag object signed with GPG
See 'git help COMMAND' for more information on a specific command.
Now we will download the Repo and get the source code:
Codes to type in the Terminal :
Code:
mkdir ~/bin
PATH=~/bin:$PATH
sudo apt-get install curl
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
mkdir source
cd source
Ok so up to this part its mostly universal. However after this you need to sync up sources for your device. This will probably take a long time depending on your internet speed since the source is very big (also it will take up a lot of drive space: 14-30GB). After that you should build.
How to build
First you will need to get proprietary drivers from your device.
Connect your device via USB and enter the following commands (from the root of your source repository):
Code:
cd device/xxx/xxx where x is the path to your device
./extract-files.sh
cd ../../..
NOTE: Some developers can include these files in the source itself or can make them available for download from their Github page. Check that out with your developer for more info.
And start the build:
Code:
. build/envsetup.sh xxx
NOTE:Here x also varies since its unique for every device model
Now Android is building. You may need to wait a long time (depending on your hardware-mainly CPU and RAM for example I have a quad core 2.92Ghz CPU and 6GB of HyperX DDR3 ram and it took me about 10min for CM7 and about 20-30 min for CM9).Once it's done you should get this message:
Code:
Package complete:xxx.zip
That is your flashable .zip file you install from recovery.
Credits: Many thanks go to Keyur Maru who helped me learn how to develop and for making the base of this guide.

Definitely one to try at home!
Sent from my GT-I9100 using xda premium

Wow 10min is real fast!! I recently tried CM9 directly from one of the Dev's forked repo and after about 4hours of build I got some build error! I need to get a better computer soon if I plan to get my hands real dirty! And if I may I have few suggestions - please mention that it will take a while to download the full repo from google sources else beginners may end up thinking something is wrong(which I did since it took me one full day to sync everything) and that it needs atleast 20-30GB disk space too..(Coz not everyone has Ubuntu as the only OS, I have three in my lapi!!)
A very good guide on the whole for a beginner!!!

Great start for me!
You have been thanked!
Great start for me!
What would the procedure be if you want to create a rom that you can flash via Odin or Heimdall on a Mac client?

The guide I've been looking for ever since I had my first Android device (actually, my Optimus Me is my first Android device)...

Thanks for this great guide. I will try it today.
I already compiled a Rom, it took me 40 min. AMD 8 Core 3,1 MHz and 16 GB DDR3
But when i try a different device i always get errors, i hope your Guide will get me in to it.

I don't know but it's surely different for odin(I'm not sure that you can).And I don't know on mac either since I use ubuntu and windows. You can look up info on this on the official Android dev website.

Odlicno objasnjeno za pocetnike. Svaka cast

Good Beginners Guide. Thank you.
But 90% of it can also be found here:
http://source.android.com/source/initializing.html
This is what i used to build android for the pandaboard a few weeks ago.
And then I have a few questions.
1.
Why do you compile git when you can also download it from apt-sources? Imho this is just confusing for beginners.
2.
Where do you use git in your tutorial?
3.
Didn't you forget lunch and make at the very end of your tutorial?
". build/envsetup.sh" only sets up the environment, imho
(see also here: http://source.android.com/source/building.html)

First you will need to get proprietary drivers from your device.
Connect your device via USB and enter the following commands (from the root of your source repository):
Code:
cd device/xxx/xxx where x is the path to your device
./extract-files.sh
cd ../../..

How do I find out what the path is from my device?

I would add the option to install Ubuntu in a VM. Both VMWare player and VirtualBox are free and well supported. This way one can actually create some pre-packaged images with which one can start development right away. In fact I've already made two of them a year ago (one for Froyo and one for Gingerbread):
http://forum.xda-developers.com/showthread.php?t=881845
http://forum.xda-developers.com/showthread.php?t=1022407
One might also make on for ICS (for that Ubuntu 12.04 is also good, and since VMWare Player is free one could use that instead of VirtualBox, as VMWP has more user-friendly features)

If I had a nickle for every time I've seen a thread like this, I would have... a nickle.
Thank you from the bottom of my /dev/hda1

True however unless you have a LOT of ram and a hexa-core CPU compilation under a vm is significantly slower and that's why I didn't add it.But the procedure is the same anyway.

1.Idk I found this thing simple as well
2.I will review it later since I'm on my phone now and its 00:13 here
3.I don't think it's necessary since I use the same procedure for my rom compilation. I will add it tough just in case someone gets an error.Thanks for the tip.

<Making Progress> Compile 2013 Nexus 7 – Flash to device – Stuck a Google boot screen

<Making Progress> Compile 2013 Nexus 7 – Flash to device – Stuck a Google boot screen
I am using the following device: 2013 Nexus 7
Android version: 4.3
Kernel version: [email protected]__ #1
Build number: JSS15Q
The problem:
When I try to flash a new boot.img file that contains my own recompiled kernel I am unable to boot the system – it sticks at the Google boot screen (and does not make it to the color X screen)
Below I have detailed out the steps I have taken. Please take a look and tell me if you notice if I am doing something wrong.
The following step were taken while running Ubuntu 12.04 LTS
*******************************************************************************************
Unlocking the 2013 Nexus 7 (Flo=wifi)
Rooting the 2013 Nexus 7 (Flo=wifi)
*** Compile/Recompile the kernel ***
*** Create a new boot.img file ***
….. contains instructions for getting root access
*** Flashing a new boot.img file ***
*******************************************************************************************
Unlocking the 2013 Nexus 7 (Flo=wifi)
Open a terminal and make sure that your system can see the Nexus 7, run:
$ ./adb devices
If you see the Nexus 7, run:
$. /adb reboot bootloader
When the bootloader screen has reappeared, run:
$ sudo ./fastboot devices
-If you can see the Nexus 7, run:
$ sudo ./fastboot oem unlock
-Look at the Nexus 7, a screen should appear asking you if you want to “Unlock the bootloader” – choose Yes.
You will need to use volume up/down to choose a response and press the power button to select.
- The device will flash a new image and exit to prompt
Next, reboot the device:
$ sudo ./fastboot reboot
The device is now unlocked.
*******************************************************************************************
Rooting the 2013 Nexus 7 (Flo=wifi)
*** Compile/Recompile the kernel ***
In the following steps you will be compiling/recompileing a kernel for the Nexus 7.
*Make sure that libncurses5-dev is installed (needed for make menuconfig)
Starting out I am at the following location
[email protected]:/home/user $
In your home directory create a folder named “Razor_Flo”:
$ mkdir Razor_Flo
Move into the new folder:
$ cd Razor_Flo
You should be here – [email protected]:/home/user/Razor_Flo $
In the Razor_Flo directory, create a sub directory named “Kernel”:
$ mkdir Kernel
Move into the new folder:
$ cd Kernel
You should be here – [email protected]:/home/user/Razor_Flo/Kernel $
[----------------- For the next steps, I used the following website to determine what files I needed -----------------]
__http__://source.android.com/source/building-kernels.html
Figuring out which kernel to build
[----------------------------------------------------------------------------------------------------------------------------------------------]
In the Kernel folder, download the following files:
$ git clone __https__://android.googlesource.com/device/asus/flo-kernel
$ cd flo-kernel
You should be here – [email protected]:/home/user/Razor_Flo/Kernel/flo-kernel $
$ git log --max-count=1 kernel
-- Log information will be displayed, under the “flo: prebuilt kernel” you will see a set of numbers and letters that will look like 365a6e0, note that number for future use.
Back out of the flo-kernel folder
$ cd ..
You should be here – [email protected]:/home/user/Razor_Flo/Kernel $
Once you are in the Kernel folder, download the following files:
$ git clone __https__://android.googlesource.com/kernel/msm.git
-- This command will create an msm directory
Move into the msm folder
$ cd msm
You should be here – [email protected]:/home/user/Razor_Flo/Kernel/msm $
[---------------------- For the next step, I used the following website to acquire the files I needed --------------------]
__http__://source.android.com/source/building-kernels.html
On a linux host, if you don't have an Android source tree, you can download the prebuilt toolchain from:
$ git clone __https__://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
[-----------------------------------------------------------------------------------------------------------------------------------------------]
Export the path to the prebuilt gcc files
$ export PATH=$PATH: <link to files>
Additional exports
$ export ARCH=arm
$ export SUBARCH=arm
$ export CROSS_COMPILE=arm-eabi-
Checkout the correct kernel files
$ git checkout 365a6e0 <-- the number you noted above
Make the Kernel
$ make flo_defconfig
* At this point you can use “make menuconfig” to make any changes to the .config file you need (i.e. kernel modifications)
$ make
* When the make is complete a file named zImage will be created here:
.../arch/arm/boot/zImage <-- Note this, you will need the file later
The kernel compile/recompile is now complete
*** Create a new boot.img file ***
In the following steps you will be taking apart the “Factory boot.img” so that you can create a “Modified boot.img” which will contain your modified and rooted kernel.
You should be here – [email protected]:/home/user/Razor_Flo/Kernel/msm $
Move up two directories
$ cd ../../
You should be here – [email protected]:/home/user/Razor_Flo $
[------------------------------------------------------- Tools need for next step -------------------------------------------------------]
You will need to download the following files.
-- split_bootimg.pl
__http__://code.google.com/p/zen-droid/downloads/detail?name=split_bootimg.pl
-- mkbootimg
__http__://code.google.com/p/zen-droid/downloads/detail?name=mkbootimg
-- 2013 Nexus Factory Images
__https__://dl.google.com/dl/android/aosp/razor-jss15q-factory-4f77b811.tgz
* You will need to copy this file to a unique location so that you can extract the “boot.img” that is located with it.
[------------------------------------------------------------------------------------------------------------------------------------------------]
Create a new folder named Workspace
$ mkdir Workspace
Enter the Workspace directory
You should be here – [email protected]:/home/user/Razor_Flo/Workspace $
Make two new folders in this directory
$ mkdir Original
$ mkdir Hacked
Move into the Hacked folder
You should be here – [email protected]:/home/user/Razor_Flo/Workspace/Hacked $
Create a new folders named Hacked_ramdisk
$ mkdir Hacked_ramdisk
Move up two directories – to the Workspace folder
$ cd ../../
You should be here – [email protected]:/home/user/Razor_Flo/Workspace $
Copy the 2013 Nexus 7 factory boot.img file into the ..Workspace/Original folder
-- can be found within the factory tgz file:
Copy the split_bootimg.pl file to the ..Workspace/Original folder
Copy the mkbootimg file to the ..Workspace/Hacked folder
Move the zIamge file to the ..Workspace/Hacked folder
Move to the Hacked folder
You should be here – [email protected]:/home/user/Razor_Flo/Workspace/Hacked $
Rename the zImage file to boot.img-kernel
Move up one directory - to the Workspace folder
You should be here – [email protected]:/home/user/Razor_Flo/Workspace $
Move to the Original folder
You should be here – [email protected]:/home/user/Razor_Flo/Workspace/Original $
Run the following command:
$ ./split_bootimg.pl boot.img
This will create two files, copy the boot.img-kernel and boot.img-ramdisk.gz
Copy the boot.img-ramdisk.gz file to the “Hacked/Hacked_ramdisk” folder
Move to the Hacked/Hacked_ramdisk folder
You should be here – [email protected]:/home/user/Razor_Flo/Workspace/Hacked/Hacked_ramdisk $
Run the following command:
$ sudo gzip -cd boot.img-ramdisk.gz | cpio -i
This will extract all the files with in the boot.img-ramdisk.gz file.
Delete the original boot.img-ramdisk.gz file that you just extracted the files from.
Edit the default.prop file
change ro.secure=1 to ro.secure=0
change ro.adb.secure=1 to ro.adb.secure=0
Save changes and close the file.
Run the following command :
$ find .| cpio -o -H newc | gzip > insecure_boot.img-ramdisk.gz
This will create a new file named insecure_boot.img-ramdisk.gz.
Rename the insecure_boot.img-ramdisk.gz. file to boot.img-ramdisk.gz and copy it up one folder in the hierarchy to the “Hacked” folder.
Move up one directory - ../Workspace/Hacked
You should be here – [email protected]:/home/user/Razor_Flo/Workspace/Hacked $
List the files in the ../Workspace/Hacked directory, there should be three files:
(1) boot.img-kernel, (2) boot.img-ramdisk.gz, & (3) mkbootimg
Run the following command from within the “Hacked” folder
$ ./mkbootimg --cmdline 'no_console_suspend=1 console=null' --kernel boot.img-kernel --ramdisk boot.img-ramdisk.gz -o mynewimage.img
Rename mynewimage.img to boot.img and flash on the device.
The new boot image is now complete and ready to flash.
*** Flashing a new boot.img file ***
[------------------------------------------------------- Tools need for next step -------------------------------------------------------]
You will need to download the following file.
-- 2013 Nexus Factory Images
__https__://dl.google.com/dl/android/aosp/razor-jss15q-factory-4f77b811.tgz
* You will need to copy this file to a unique location so that you can extract the “system.img” file that is located with it.
--- Android SDK (I used the 64-bit version)
__http__://dl.google.com/android/android-sdk_r22.0.5-linux.tgz
[------------------------------------------------------------------------------------------------------------------------------------------------]
You will need to use both the adb and fastboot utilites that come in the Android SDK application.
You will need two image to complete this task
1. boot.img <--file you just created, located in the ../Workspace/Hacked directory
2. system.img <-- can be found within the factory tgz file:
Starting out I am at the following location
[email protected]:/home/user/android-sdk/platform-tools $
Place both the boot.img and system.img files into the same folder as the adb and fastboot utilites.
Verify that you can see the Nexus 7 device that you are about to flash
$ sudo ./adb devices
*if you cannot see the device, make sure that you have checked the “enable USB Debugging” in the developer options.
Run the following commands
$ sudo ./adb reboot bootloader
$ sudo ./fastboot flash boot boot.img
$ sudo ./fastboot flash system system.img
$ sudo ./fastboot format cache
$ sudo ./fastboot format userdata
$ sudo ./fastboot restart
At this point the system should be unlocked and rooted.

I used this and I got it working:
http://source.android.com/source/initializing.html
I created the msm directory inside the flo-kernel directory as a place to put the kernel source. I don't know if that is right, or if it even matters, but it works for me. Then I had to move the zImage to out/product/target/flo/kernel before doing the make on the framework. Don't forget to do the "source build/envsetup.sh" and "lunch" before making the framework. Before compiling the kernel, be sure to set ARCH, SUBARCH and CROSS_COMPILE environment variables and make sure your PATH includes the prebuilt cross-compiler.

Making headway
Ok, So I made some headway lastnight.
I have not figured out how to compile the kernel on my own however, I am able to compile and boot an AOSP image for the 2013 Nexus 7
My problem getting the image to boot once compiled centered around drivers. I was under the impression that Android would work like Linux and Windows... meaning that if you did not have device drivers installed the OS would still boot - I was wrong. After installing the drivers (via the provided install .sh files) I then compiled the OS, flashed the device, and the system boot.
Now I am off to figure out how to get a custom kernel running.

For the benefit of others who might look at this forum in the future.
This is what is required to be done.

I faced the same problem and took time to figure out what it really meant.
Also if it is in an infinite loop after the above procedure. Try doing fastboot flashall -w
-w option did the magic for me when I was stuck in an infinite loop after the above procedure.

Guide: How To Build Your Own Stock AOSP For Your Nexus 7 (2013) KVT49L

PHP:
Guide: How To Build AOSP From Source With Linux Mint 16 - Nexus 7 (2013) KVT49L
Important Note: Do NOT use Linux Mint 16 KDE to do this guide, it will seriously mess up your programs menu when you remove the old Java. This guide has been tested and is working on Linux Mint 16 Cinnamon and Linux Mint 16 MATE
Got the KVT49L repos working and guide is updated to reflect this. This build includes several bug fixes from the KOT49H build but it is NOT 4.4.3, just an updated version of 4.4.2.
I started this guide as I could not find a step by step detailed guide to build a stock AOSP from source with Linux Mint 16.
All the steps should work in Ubuntu but I haven't tried so not 100% sure of that.
All this assumes your tablet is already unlocked.
Here goes:
Important note: Anything that is bolded text other then section titles are command line entries that are done in Terminal in Linux Mint. I thought it would be simpler to do it this way then say 'in Terminal' for every entry.
First we need to remove Icedtea Java or OpenJDK.
In Terminal: sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
Then in Terminal: sudo add-apt-repository ppa:webupd8team/java
Next: sudo apt-get update && sudo apt-get install oracle-java6-installer
Be sure to accept the licence agreement to install java when it prompts you.
Next: sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 libc6-dev lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 lib32z-dev libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc readline-common libreadline6-dev libreadline6 lib32readline-gplv2-dev libncurses5-dev lib32readline5 lib32readline6 libreadline-dev libreadline6-dev:i386 libreadline6:i386 bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev lib32bz2-dev libsdl1.2-dev libesd0-dev squashfs-tools pngcrush schedtool libwxgtk2.8-dev python
Follow this with: sudo apt-get install -f
This should fix any dependency errors.
Now: sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
Next download the SDK Tools For Linux x64 from this link. https://developer.android.com/sdk/index.html
Then: cd ~/Downloads
And: tar -xvf android-sdk_r22.6.2-linux.tgz
or tab the latest 'android-sdk_xxx.tgz file it they update it and it is a newer version then the one I downloaded to do this.
You can rename the android.sdk_xxx.tgz folder you extracted to SDK.
Then: cd ~/Downloads/SDK/tools
Next: ./android sdk
It will show you the tools that can be installed, just install the highest version API of 'Platform Tools' and 'Tools' for the latest android version '4.4.x' it shows.
Make sure you install the repo tool, in Terminal:
With: mkdir ~/bin
Then: curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
And: curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
Now: sudo chmod a+x ~/bin/repo
Now sudo nano ~/.bashrc
Add this to the bottom of the text: export PATH=~/bin:$PATH
Then hit Ctrl-O and enter, it should say it saved the file followed by Ctrl-X to exit.
Then restart bash: source ~/.bashrc
Now lets Initialize the Repository for GIT configuration
First : git config --global user.name {Your Name}
Then: git config --global user.email {[email protected]}
If you have not registered with the GitHub website just doing these two steps works fine.
If you have registered with the GitHub website create a file called .netrc in your home directory, add your GitHub password to it with no spaces on the first line and change the permissions to '600' or you will have to continually authenticate when building the source.
In Terminal:nano ~/.netrc
Then add just your GitHub password (like I said you only need to do this if you have registered with GitHub).
Then 'Ctrl-O' and enter and it'll say it saved it, then 'Ctrl-X' to exit nano.
And then: chmod 0600 ~/.netrc
Now: mkdir ~/AOSP
Then: cd ~/AOSP
Now you get the source code etc: repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.2_r2
Then do in Terminal : repo sync -j12
Use repo sync -j12 for a quad core CPU or Intel I5 or if you have say an quad core I7 with 8 threads you can use repo sync -j24 to speed things up etc.
I have a I7 3930k with 12 threads so I used repo sync -j36. This gives you three threads per logical CPU and speeds things along quite well.
It may take several hours for the sync to finish.
After the sync finishes go to https://developers.google.com/android/nexus/drivers#razorkot49h and download the drivers (binaries) for the Nexus 7 (Wi-fi). You do need to use the KOT49H binaries and they work fine with the KVT49L build.
In Terminal: cp ~/Downloads/asus-flo-kot49h-a9532596.tgz ~/AOSP
Then: cp ~/Downloads/broadcom-flo-kot49h-c33beb3d.tgz ~/AOSP
And: cp ~/Downloads/qcom-flo-kot49h-f92d75b1.tgz ~/AOSP
In Terminal: tar -xvf asus-flo-kot49h-a9532596.tgz
And: tar -xvf broadcom-flo-kot49h-c33beb3d.tgz
Then: tar -xvf qcom-flo-kot49h-f92d75b1.tgz
If you have closed the Terminal after the sync remember to do: cd ~/AOSP
when you open Terminal again before doing the tar commands.
They should be the file names of the binaries for KOT49H that you are extracting but if for any reason the file names are different use the Tab key and tab the correct names in after 'tar -xvf'.
If the names ARE different I'd really check to make sure you downloaded the correct flo binaries.
Then: ./extract-asus-flo.sh
Now also in Terminal: ./extract-broadcom-flo.sh
And: ./extract-qcom-flo.sh
Hint: It will show you a really long licence agreement for each binary that you scroll by hitting the Enter key that takes forever to scroll one line at a time, it has 8 sections and several subsections. Hold the Enter key until you just get past Part 8, section D of the licence and stop there. Now hit enter a few more time one key stroke at a time until you finish Part 8 section E and see the 'Type 'I ACCEPT' to agree to the licence.' and type I ACCEPT If you just scroll by holding the Enter key all the way to the bottom of the licence you'll get an error you never accepted the licence. Then close Terminal.
Building the Sources
Now open Terminal: cd ~/AOSP
Then: . ./build/envsetup.sh
Now to select the type of device we give the following command: lunch
Choose: 11. aosp_flo-userdebug
by entering '11' or whatever number aosp_flo is after your enter the 'lunch' command (it was number 11 on mine).
Now: make -j12 for a quad core cpu or I5 or make -j24 for an I7 etc.
With your tablet connected to your USB cable and the PC: adb root
Then: adb reboot bootloader
And: cd out/target/product/flo
Lastly: fastboot -w flashall
If you get an error on the 'adb' and 'fastboot' commands do these first:
sudo apt-get install android-tools-adb
and: sudo apt-get install android-tools-fastboot
If you get an error when you fastboot -w flashall to do with a '-p' flag needed or 'android-info.txt' is missing it means you forgot to to the 'lunch' command before building the source. Go back to the 'Building The Sources' section.
If you already have a custom recovery installed like TWRP and would rather build a zip file to install with the recovery rather then flash it in adb instead of make -j12 do: make -j12 otapackage
In the /home/"yourusername"/AOSP/out/target/product/flo you have an aosp_flo-ota-eng.___.zip file to flash in your custom recovery.
You will need to wipe/reset data your in recovery before flashing it and re-install all your apps etc.
Installing Custom Recovery, Rooting and Google Apps
If you want to install a custom recovery download TWRP http://techerrata.com/browse/twrp2/flo
Rename the file in Downloads to recovery.img
Then in Terminal with your tablet connected by USB to your PC: adb root
And: adb reboot bootloader
Then: cd ~/Downloads
And: fastboot flash recovery recovery.img
Use the volume buttons on your phone to scroll onto "Restart Bootloader" and hit the powerbutton to select it. After the bootloader reloads, use the volume buttons to scroll to "Recovery Mode" and hit power button again to select it. You should then be in your custom recovery.
If for any reason you get a red android and no recovery just boot into fastboot mode again and reinstall the recovery.img.
And finally, to root your tablet download SuperSu http://download.chainfire.eu/supersu and install the supersu.zip in recovery mode.
Download PA GAPPS from here http://forum.xda-developers.com/showthread.php?t=2397942 if you want the zip to install Google Apps in recovery.
You now have your own rooted vanilla AOSP you compiled yourself, congrats!
P.S. Very likely a good idea wipe/reset data in recovery and start with a clean install, you'll need to install all your programs and stuff anyways I'm sure.
P.P.S.I did download and install the XPOSED Framework apk http://forum.xda-developers.com/showthread.php?t=1574401 after I put AOSP on my tablet so I could install Advanced Power Menu and some other add-ons like Boot Manager and Greenify. As well I installed a custom kernel with Faux Sound and Faux Kernel enhancements.

I think for the download repo tool section you only need the second (commondatastorage) one. The first one no longer works.
Other than that, it looks pretty good.

Awesome thanks!!!

Edit: I see the problem with the second curl command, when I save the post it shortens the url in the command with dots and when you copy and paste it it is incorrect and does not download, I'm trying to figure out how to fix it, every time I save the post no matter if I take the url code out or not it shortens it.
Second edit: I figured out a work-around and added it to the guide. It's half baked how I had to do it but at least it's working now.

hey all, sorry if this is off topic, but ive been looking for help everywhere and im about ready to give up, im trying to build evervolv for flo, i've got the source downloaded and im ready to build, the only thing im having trouble with is getting all the propratairy blobs and device spacific files from the n7. is there a way i can just sync up with cyanogenmods device repo or over right the repo that is build into evervolvs source? thanks for any help.

download the binaries and extract them as was shown in the OP.
Then do
make clobber
. build/envsetup.sh
lunch
make (whatever option you decide, otapackage etc)
Make clobber is important because it ensures you start clean and that the binaries will be properly implemented in your rom.

I think you had the "commondatastorage" one right before. It is the "curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo" that doesn't work anymore.
So instead of those two steps, it should be just this one:
Download the Repo tool and ensure that it is executable:
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
I hope that makes more sense.

Great post! Thanks for this!

I fixed the second curl command so it works. Not 100% sure you need the first curl command but it does work in Linux Mint 16 and doesn't mess anything up so I left it in.

[GUIDE]Creating your own Firefox ‘Data Saver’ proxy Browser

Introduction
Hello XDA. My name’s Chris and in this guide I’ll try to show you how to set up your own independent “Data Saver” proxy similar to the one we know from Google Chrome browser. I have to warn you that the steps needed require moderate knowledge and might not be easy to follow for the beginners. It also requires setting up some software on your server (Ubuntu 16.04 in my case) prior to following this guide. You can find tutorials on how to do so in Prerequisites section below.
Prerequisites
- Server running Linux distro (Ubuntu 16.04 x64 in my case as I said above)
- Wireguard or other VPN (OpenVPN) setup on the server that is useable on your device (I’ll go with wireguard, so here’s a great tutorial to set that up: https://www.digitalocean.com/commun...t-to-point-vpn-with-wireguard-on-ubuntu-16-04 . It's pretty straightforward.)
- Machine to build (preferably gcloud or some other buildserver)
- Time
Environment
We’ll start of with installing libraries & additional tools needed to build Android itself just to make sure everything’s ready to move on later:
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 opting libjpeg8 libjpeg-dev openssl ssl-cert maven mercurial libnss3-tools
Okay, so that’s about it for automated install of packages. We’ll also need newest version of golang and Ubuntu repos do not provide that by default so we will install It and set work directory manually:
Code:
mkdir -p ~/golang
cd ~/golang
wget https://dl.google.com/go/go1.10.1.linux-amd64.tar.gz
tar -xvf go1.10.1.linux-amd64.tar.gz
sudo mv go /usr/local
mkdir -p ~/go
Now that it is installed let’s add it to our PATH environment by editing .profile:
Code:
sudo nano ~/.profile
Add these lines at the end of the file:
Code:
export PATH=$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
Save the file and run
Code:
source ~/.profile
To refresh your env setup.
That’s it for now when it comes to your environment setup. We may be installing other packages needed in this guide later.
Installing the Proxy server
Let’s proceed to setting our proxy server that will do all the compression work we want it to. We’ll be using Compy proxy here since it supports ssl which is a must for almost all modern websites nowadays. Let’s download the source we need:
Code:
go get github.com/barnacs/compy
Now we are ready to compile our proxy server binary:
Code:
cd go/src/github.com/barnacs/compy/
go install
Our binary should be located in ~/go/bin so lets try to run it and see if it’s okay
Code:
cd ~/go/bin
./compy -help
This should print all of the arguments we can pass to our proxy. I prefer to have easy access to running it on boot without setting any paths so I’ll move my binary to /usr/bin of my server.
Code:
sudo mv compy /usr/bin
sudo chmod a+x /usr/bin/compy
Generating Self-signed Certificate & Running the Server
Since w plan on using our proxy with SSL traffic we have to provide our own SSL certificate. I just went ahead an generated self-signed to not bother myself with getting it the other way:
Code:
mkdir -p ~/keys
cd ~/keys
openssl req -x509 -newkey rsa:2048 -nodes -keyout cert.key -out cert.crt -days 36500
openssl is going to ask you a few details. Fill those in however you want as it doesn’t matter much since you will be the only one using that certificate anyway. After doing so you should have two files in your keys folder:
Code:
cert.key
cert.crt
Now you may test run compy with those keys to see if everything’s okay. I’ll run it on port 8888:
Code:
compy -host :8888 -ca ~/keys/cert.crt -cakey ~/keys/cert.key -gif false -brotli 8 -gzip 7 -jpeg 75 -png -minify
As you can see we have our keys specified twice. That’s due to workaround applied earlier, don’t worry about it. If everything’s okay you should now see something like this:
Code:
2018/04/05 09:46:49 compy listening on :8888
Since our proxy server seems to run correctly, we may also add some iptables to make it accessible only from our VPN peer address:
Code:
sudo apt-get install iptables-persistent
sudo iptables -A INPUT -p udp -s 10.0.0.0/24 --dport 8888 -j ACCEPT
sudo iptables -A INPUT -p tcp -s 10.0.0.0/24 --dport 8888 -j ACCEPT
sudo iptables -A INPUT -p udp -s 0.0.0.0/0 --dport 8888 -j DROP
sudo iptables -A INPUT -p tcp -s 0.0.0.0/0 --dport 8888 -j DROP
sudo dpkg-reconfigure iptables-persistent
From now on your proxy should be accessible only through your Wireguard VPN connection. At this point it’s safe to run our proxy in the background at system bootup. I do that via crontab:
Code:
sudo crontab -e
Add this line in the end of a file (change the settings if you want to):
Code:
@reboot compy -host :8888 -ca ~/keys/cert.crt -cakey ~/keys/cert.key -gif false -brotli 8 -gzip 7 -jpeg 75 -png -minify
Save the file and you're done with server config.
Server is ready. What now?
Now we need a way to make use of our server and that’s the moment where the fun begins. We could of course add our SSL certificate to Android system certs and try to use our proxy globally BUT that will result in most of apps refusing to connect to their services due to SSL Pinning as our MiTM proxy signs the traffic with our self-signed certificate so non-browser traffic would be essentially dead. Since I haven’t found reliable way to set proxy for individual apps nor disable SSL Pinning on Android 8.1 I had to try my luck finding browser that support proxy setup and Firefox does just that via about:config.
Here comes another problem. Firefox doesn’t use system certificate store so trying to setup our proxy there will result in “Unsafe connection” errors that won’t allow us to visit any website due to the fact the browser doesn’t trust our certificate. I also haven’t found any reliable way to add the cert into newest versions of the browser so the easiest way around that was compiling it from source with the certificate bundled in. Well, let’s go then.
Sync Fennec source
Development variant of Firefox is named Fennec. I recommend doing these steps on some build server as it will be faster than on regular machine. We will use Mercurial to download newest source. It got installed when we were setting up our Env so you can just proceed to clone the repo:
Code:
mkdir -p ~/fennec
cd ~/fennec
hg clone https://hg.mozilla.org/mozilla-central
Wait for the sync to complete. It can take a while so in the meantime we can go forward with other things.
Prepare certificate for Fennec
So we have our cert files we generated earlier used by the proxy. Now we need to convert our cert to format used by mozilla in their browser sources. First we need to convert our certificate into .der format
Code:
cd ~/keys
openssl x509 -in cert.crt -out cert.der -outform DER
Then we will convert it into certdata.txt format for us to use.
Code:
nss-addbuiltin -n ProxyCert -t "C,C,C" -i cert.der >> certdata.txt
We should get quite lengthy file certdata.txt that contains our certificate in the format needed by Fennec sources. We will add it there in a few moments.
Adding the certificate into browser source
Okay so the sync finished and our certdata is ready. Now we need to append it to file provided in Fennec sources:
Code:
cat ~/keys/certdata.txt >> ~/fennec/mozilla-central/security/nss/lib/ckfw/builtins/certdata.txt
Now our browser is ready to be built.
Building Fennec
Let’s move on to our final part: Building the browser. First let the building environment setup by itself.
Code:
cd ~/fennec/mozilla-cental
./mach bootstrap
You will be prompted with a question which version of Firefox you want to build. Naturally, I chose 4. Firefox for Android. Some additional package installs and dependencies downloads will occur at this point. This might take some time. You may need to agree to Android SDK licence and make some other chocies like Mercurial install. Choose Do not install Mercurial as we have it already. Then in another Mercurial dialogue choose No.
After the sync is complete we will get the suggested content of mozconfig file that is needed for the build:
Code:
# Build Firefox for Android:
ac_add_options --enable-application=mobile/android
ac_add_options --target=arm-linux-androideabi
# With the following Android SDK and NDK:
ac_add_options --with-android-sdk="/home/chris/.mozbuild/android-sdk-linux"
ac_add_options --with-android-ndk="/home/chris/.mozbuild/android-ndk-r15c"
Create the file with nano and paste your config there:
Code:
nano mozconfig
Now before we start the build we will need to update gcc toolchain since Ubuntu 16.04 comes with gcc 5.4 and Fennec needs at least 6.1 to build:
Code:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
sudo apt-get update
sudo apt-get install gcc-6 g++-6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-6
Verify our install with gcc -v
Code:
gcc version 6.3.0 20170519 (Ubuntu/Linaro 6.3.0-18ubuntu2~16.04)
We also need to download rust toolchain for arm target and then we may start the build:
Code:
source ~/.profile
rustup target add armv7-linux-oideabi
./mach build
This will take a lot of time. On Google Cloud build took me around 50 minutes so you may take your rest now and go out for a walk/grab some coffee etc. Anyway, after it’s done run:
Code:
./mach package
To generate your new browser fennec-61.0a1.en-US.android-arm.apk file. It should be somewhere in
Code:
~/fennec/mozilla-central/ objdir-droid/dist
Copy it over to your device and install. Time for some tests.
Setting up the browser & Testing
After installing your fresh Fennec build proceed to open about:config in the address bar and setup proxy as follows (replace ip and port with the ones you used):
Code:
network.proxy.http
10.0.0.1
network.proxy.http_port
8888
network.proxy.ssl
10.0.0.1
network.proxy.ssl_port
8888
network.proxy.type
1
network.proxy.no_proxies_on
10.0.0.1
Try to load any https website while running compy proxy on your server. It should work now:
