As you all may know (or may not know or may not even care), Google's current implementation of ADB for Linux only works on 32Bit Linux systems (boooh!) which leaves the rest of us x64 users with the dilemma of either installing an extra redundant 32bit version of Ubuntu that will hord 15Gb of space so that we may type a few ADB commands in the bash prompt or install ADB on Windows for those of us that have it. Ever since I bought my phone and was forced to reboot my beloved free OS to type those few commands, I'd wave my fists in the air and curse Google for not having had enough sense to make a 64Bit implementation.
Fortunately, my fists will need tire themselves no more. Using a guide compiled by a Geeksphone.com forum user called Talpa, I was able to successfully compile and run ADB on a Linux 64Bit system in short order. Little things make me happy and having seen that this technique is not very wide spread on the forums, I've decided to spread the happiness myself...
CREDITS:
Big, big thanks to the users of the geeksphone forums for having pooled their time, skills and efforts together to figure out this hack and a another big thank you to talpa for having sifted through all the of posts and having made a coherent and unified guide out of it. The guide can be originally found at:
http://wiki.geeksphone.com/en/index.php?title=CompileADB64bitLinux
the discussion that lead to the guide is at:
http://forum.geeksphone.com/index.php?topic=850.0
ADB Linux 64Bit (yeeehhhaaaah!!!)
For the sake of added clarity, I've completely rewrote the geeksphone guide. go to your terminal
#> sudo su
#> mkdir /tmp/my-adb
#> cd /tmp/my-adb
if you don't already have it, install git-core:
#>apt-get install git-core
once that's done, type out the following commands:
#> git clone git://android.git.kernel.org/platform/system/core.git system/core
#> git clone git://android.git.kernel.org/platform/build.git build
#> git clone git://android.git.kernel.org/platform/external/zlib.git external/zlib
#> git clone git://android.git.kernel.org/platform/bionic.git bionic
Before you run compile, you need to the following alterations to the compile scripts to make the output bianaries 64bit compatible. As time progress and this post ages in the ageless internet, some additional modifications may be necessary (or they may change the place of the offending code or may add new bits that need to be deleted or changed). You can go back to the GeeksPhone wiki link (up above) to see if the forum members there have updated it. Hopefully by then, Google would have compiled a 64Bit Linux version of ADB and all of this would be unnecessary. If for any reason you're unable or unwilling to modify the source code yourself, go to this link where I have posted the source code that I have modified:
http://www.mediafire.com/file/q42gektqr32nr31/adb-Linux64bit-source-code-jan-2011.zip
Editing the Source Code Yourself
first, edit the file /tmp/my-adb/build/target/product/sdk.mk and delete the last six lines:
==============================
# include available languages for TTS in the system image
include external/svox/pico/lang/PicoLangDeDeInSystem.mk
include external/svox/pico/lang/PicoLangEnGBInSystem.mk
include external/svox/pico/lang/PicoLangEnUsInSystem.mk
include external/svox/pico/lang/PicoLangEsEsInSystem.mk
include external/svox/pico/lang/PicoLangFrFrInSystem.mk
include external/svox/pico/lang/PicoLangItItInSystem.mk
==============================
then, edit the file /tmp/my-adb/build/core/main.mk at line 116 (again the position may change, just keep an eye out for the offending code) and erase the following lines:
==============================
# Check for the correct version of java
java_version := $(shell java -version 2>&1 | head -n 1 | grep '[ "]1\.6[\. "$$]')
ifeq ($(strip $(java_version)),)
$(info ************************************************** **********)
$(info You are attempting to build with the incorrect version)
$(info of java.)

endif

$(info Please follow the machine setup instructions at)
$(info $(space)$(space)$(space)$(space)http://source.android.com/source/download.html)
$(info ************************************************** **********)
$(error stop)
endif
==============================
Edit /tmp/my-adb/build/core/combo/HOST_linux-x86.mk and change every "-m32 string" to "m64"
Now that that's done, you should be able to get the compiling going with the following command:
#> make -f build/core/main.mk out/host/linux-x86/bin/adb
Once that's done, you go to /tmp/my-adb/out/host/linux-x86/bin/ and you get your adb and acp binaries and move them to wherever your OS keeps all the system binaries.
In ubuntu 10.04, that would be
/bin/adb
/bin/acp
That's it, adb should work from your 64 bit linux shell.
==========================
Holy hell that looks overly complicated. I've installed adb about a dozen times on x64 Ubuntu. I'll post a link to the guide i was using in a minute...

You need to do lsusb in console (with your phone plugged in) and find the Samsung vendor id, it's like 0ed4 or something, I don't remember.
Much easier, I think.

Um, yeah, I don't know why the OP is doing all this. All you need to do is download the android SDK for your platform:
http://developer.android.com/sdk/index.html
An adb binary is included in the tarball in the tools directory. Just add that to your path somewhere.
Yes, the binary included in the SDK is 32bit. No, it doesn't matter at all. A clean install of 64-bit Ubuntu includes multilib support for the (very few) 32-bit shared libraries it requires.
If you really, really need a 64-bit binary... well, go for it. But unless you're building your own Linux distribution or are doing something really exotic, it's highly likely that the 32-bit version will work just fine.
Yikes! This is overkill. Dude, just install the lib32 library files. You should really read the Android developers page on how to setup the sdk on 64-bit linux, its all there. ;-) Good luck with this though. Really...

I thought some people might appreciate the instructions to get adb working over WiFi too and this seems like a good place to put it:
Type this in your terminal emulator on your Android device:
Code:
setprop service.adb.tcp.port 5555
stop adbd
start adbd
Then check it with this:
Code:
getprop service.adb.tcp.port
If it doesn't return "5555" and you're rooted, then do a "su" command and try again. You shouldn't need to be rooted for adb over wifi to work, but I haven't tried every device:
Code:
su
setprop service.adb.tcp.port 5555
stop adbd
start adbd
Then check it:
Code:
getprop service.adb.tcp.port
When it returns "5555" then run this command in the terminal (or command prompt) on your computer:
Code:
adb connect 192.168.0.151
(Obviously enter your device's IP address. You must be on the same network as the computer that has the Android SDK installed.)
And you should be connected!
To tell the Android device to listen for adb on the USB port instead of TCP again, enter this into the terminal emulator:
Code:
setprop service.adb.tcp.port -1
stop adbd
start adbd
(again, might need "su" on your device)
Or just reboot the Android device.
And to tell your computer to use USB for adb instead of TCP:
Code:
adb usb
Now, keep in mind, when your Android device is listening for adb via WiFi, it's wide open... anybody that that the Android SDK installed and knows your device's IP address can access it without a password.
HTH,
Billy

Yes, I just installed a clean Ubuntu 64 bit and the lib32 binaries were included. I only needed to create a /etc/udev/rules.d/70-android.rules and enter my device ID - SUBSYSTEM=="usb", SYSFS{idVendor}=="18d1", MODE="0666". I can connect via ADB 32 bit just fine.
Of course using 64 bit drivers falls under the I did it because I could category as well. Kudos!

Exactly my thoughts as well. It is simple enough to get it working using the standard package that Android provides!
Like others have said adb packaged with the android sdk works fine on ubuntu 10.10 with no additional configuration. The only problem that I know of is you have to run the adb server as root.

I'm pretty sure that you only have to give it root on the first time.

I am able to run the adb server with a user login with guest permissions. Did not have to use root. But I run Ubuntu 10.04. I guess that it would probably be the same for 10.10 as well, but can't confirm.
This is what I do (very simple and fast)
1) Open the terminal and type: wget dl.google.com/android/android-sdk_r07-linux_x86.tgz (Downloads The SDK with ADB)
2) Then type: tar xvfz android-sdk_r07-linux_x86.tgz && cd android-sdk-linux_x86 (Extracts the archive)
3) After that type: sudo mv tools /usr/local/share/android-tools (Moves the sdk tools to your local system folder)
4) Now type: sudo ln -s /usr/local/share/android-tools/adb /usr/local/bin/ (Makes a symbolic link to the adb executable)
5) Then type: sudo adb devices (This will start the adb server and search for connected devices)
You should now see this in your terminal:
List of devices attached

Firstly, Thanks a lot to the OP for posting this and the link to the geeksphone wiki. I really needed this and I would have removed my existing linux install, had I not come across this in the next few minutes.
Now back to the main reason why I am posting this comment.
I didn't see even one single reply that was grateful to the OP and the first many posts were just plain crap. If you people don't know what someone is talking about, then please don't show your ignorance and move on to troll other threads.
Of course you can install adb from the default google sdk package and it would work fine on 99% of your systems. It is the remaining 1% for whom this post is intended.
This method is for those who have a pure non-multilib 64-bit system. For such users, google has not packaged a 64-bit adb file in their release, and the default adb will not work. Such users have to build the adb file for a 64-bit machine from the sources. It is for such users that this is necessary and it was very much necessary for me, as well as for the OP, I presume.
So if you don't understand something, please don't waste others' time by spamming the post. The title is quite obvious to those who are looking for a solution.
Update: Just as I finished typing this, my adb has got compiled and I am able to run it. Thanks a million once again, OP.

damn!
The adb tool has moved to platform-tools/
If you don't see this directory in your SDK,
launch the SDK and AVD Manager (execute the android tool)
and install "Android SDK Platform-tools"
Please also update your PATH environment variable to
include the platform-tools/ directory, so you can
execute adb from any location.
ofcourse they meved it. so ... any new tutorial with android sdk ?
in windows is the same problem with missing adb.exe (but i have an older version installed). just that i use windows for starcraft2 so i want adb for linux (eventually x64).
later edit: found it ->scroll down to platform tools
and after:
extract in a folder, cd to that folder
$sudo apt-get install lib32ncurses5 lib32stdc++6
# echo SUBSYSTEM=="usb", SYSFS{idVendor}=="0bb4", MODE="0666">/etc/udev/rules.d/51-android.rules
$./adb kill-server
$./adb start-server
(kill and start i don`t know if is necessary, but it can`t do nothing wrong)
connect the device, $./adb devices and shall see it.
$./adb shell and enjoy
$ => as regular user
# => as root
i`m on kubuntu 12.04 (x64) and using an android 2.3.7 (cm7 based) huawei u8180 / orange stockholm
even easier
even easier paste these commands in linux terminal
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install android-tools-adb android-tools-fastboot

I'm doing this guide because when I switched to arch linux ,I found no guides to setup sdk in it.Arch is a beautiful OS, but for newcomers like me ,I took some time to get used to it.So,In this guide, we’ll take a look at how to set up a development environment for Android in Arch linux(or Arch based Linux Distros) so you can start working on your Projects.Most of the Arch Linux are pro linux users so there is really no need of this guide, but this guide is meant for those who are switching from ubuntu/mint/fedora/any other disto which are not based on Arch, to say it in short its meant for new users of Arch Linux. Anyway Let's set up.
First let's set see how to install Platform tools.
Setting up platform-tools in UBUNTU(or Ubuntu based distros/Linux Mint)
In ubuntu platform tools can be setup very easily.
1.Open terminal(Default shortcut is ctrl+alt+T)
2. Type "sudo apt-get install android-tools-adb" (this will install the adb)
3. Type "sudo apt-get install android-tools-fastboot"(this will install the fastboot)
Step 4: Check whether the above tools are working by typing an adb command. For e.g. "adb devices"
Now its time to install SDK in Ubuntu and set it up but before that let me tell you there is already a great thread by matt95.You can see the guide and thank him herehttp://forum.xda-developers.com/showthread.php?t=2302780
Fedora/CentOS/RedHat
First lets install Eclipse[You can also use Android Studio if you want]
Code:
sudo yum install eclipse-jdt
Now lets download the sdk from here. http://developer.android.com/sdk/index.html. Its about 500mb , Just wait and let it downlaod. Once the download is done extract it wherever you want.
For newcomers I recommend to extract it to 'home'.So the file is now extracted inside /home/user/AndroidSDK .
Now lets setup .bash_profile file so that we can access adb anywhere or else you have to type the whole location again use the adb command which is lot of work . So let's shorten it up.
Type "sudo vim .bash_profile"in terminal.
Code:
PATH=$PATH:$HOME/AndroidSDK:$HOME/AndroidSDK/tools
export PATH
# For SDK version r_08 and higher, also add this for adb:
PATH=$PATH:$HOME/AndroidSDK/platform-tools
export PATH
Now lets install android plugin for eclipse.
Open Eclipse and click on Help.Select Install New Software. Then click Add, at the top right of that window. Type in Android Plugin for the name and https://dl-ssl.google.com/android/eclipse/ for the address.
Once this is done, click on the Available Software Sites hyperlink below the Add button, then highlight the Android Plugin source and click on Reload. Now exit this window, and choose Android Plugin from the “Work with” dropdown menu. Choose the developer tools option that you see here and Proceed with the installation.
After the installation configure your Android virtual devices.
ARCH LINUX(or Arch based Distros)
Lets install android sdk
Open terminal and type
Code:
wget https://aur.archlinux.org/packages/an/android-sdk/android-sdk.tar.gz
Note:- If terminal shows wget is not found. Type this in the terminal
Code:
pacman -Suy && pacman -S wget
Once it fetches the tarball, lets extract it by typing
Code:
tar -xvzf android-sdk.tar.gz
wait for it to finish. Change the directory to android-sdk by using the command
Code:
cd android-sdk
.
Now lets make the package by using the command
Code:
makepkg -s
now lets install it by typing
Code:
sudo pacman -U *.pkg.tar.xz
Platform tools for Arch
Let's install platform-tools now.Just like above steps ,well get a package and install it.
1. Type
Code:
wget https://aur.archlinux.org/packages/an/android-sdk-platform-tools/android-sdk-platform-tools.tar.gz
2.Type
Code:
tar -xvzf android-sdk-platform-tools.tar.gz
3.Change directory.
Code:
cd android-sdk-platform-tools
4.
Code:
makepkg -s
5.Install it
Code:
sudo pacman -U *.pkg.tar.xz
All the files are installed in /opt/android-sdk/ . Just like we had .bash_profile in FEDORA, we use symbolic links in Arch linux to use commands from anywhere .
Code:
sudo ln -s /opt/android-sdk/platform-tools/adb /usr/bin/adb //this one's for adb
sudo ln -s /opt/android-sdk/platform-tools/fastboot /usr/bin/fastboot //This one's for Fastboot
sudo ln -s /opt/android-sdk/tools/ddms /usr/bin/ddms //This is for DDMS
sudo ln -s /opt/android-sdk/tools/android /usr/bin/android //This is for Android
Now run android by typing "android" in terminal. :good:
Simple as that. If you are yet to switch to Arch linux then I recommened you to use "BBQLinux " its an Arch linux for Android developers. It comes with most of the things needed for android development. You can download it from Here.
Thanks for reading this. Help me by giving me e-books.:angel:
PM me or post here if you have any doubts. :victory:

you dont need both platform and build tools, it looks like build-tools is more recent. if you want eclipse instead of android studio, just use 'eclipse-android' instead of android-studio
Hello,
I am taking my first steps into trying to create an Android app.
In installed Android Studio 1.5.1 on Linux Mint 17.3 (kernel 3.19.0-32-generic, 64-bit). JRE version is 1.7.0_95-b00 amd64 (according to the about box).
I try to run the app in the emulator. I have created a virtual device, with the following details:
Code:
Name: Moto_X_Play_API_23
CPU/ABI: Google APIs Intel Atom (x86_64)

If I select this virtual device I get the following error message:
Code:
Cannot launch AVD in emulator.
Output:
WARNING: Cannot decide host bitness because $SHELL is not properly defined; 32 bits assumed.
ERROR: 32-bit Linux Android emulator binaries are DEPRECATED, to use them
you will have to do at least one of the following:
- Use the '-force-32bit' option when invoking 'emulator'.
- Set ANDROID_EMULATOR_FORCE_32BIT to 'true' in your environment.
Either one will allow you to use the 32-bit binaries, but please be
aware that these will disappear in a future Android SDK release.
Consider moving to a 64-bit Linux system before that happens.
I downloaded an example app, but that results in the same error.
Why does Android Studio or the emulator think it is running on a 32-bit system?
How can I get rid of this error?
The emulator uses the shell to define if you are running a 32 or 64 bits machine.
The $SHELL environment variable doesn't seem to be defined in your case
Try to launch Android Studio from a terminal:
Code:
$ <YOUR_ANDROID_STUDIO_INSTALL_DIR>/bin/studio.sh
If this works, try to create a menu entry starting the following command:
/bin/bash <YOUR_ANDROID_STUDIO_INSTALL_DIR>/bin/studio.sh
I am running Android Studio from a terminal, I don't have a menu entry for it.
If I change the command into
Code:
export SHELL=/bin/bash && android-studio/bin/studio.sh
the emulator runs fine.
Another account on the same machine has the environment variable SHELL set automatically. Both accounts do not have a .bashrc in their home directory. The both have identical .pam_environment and .profile files.
From where could it have been set?

Well AFAIK, the SHELL environment variable is set by the shell executable itself when it starts. It looks like something unsets it on your system.
You already checked the 3 files that came to my mind.
Maybe one of the global environment file (/etc/environment, /etc/bash.bashrc, /etc/profile or /etc/profile.d/*) But I doubt it as you would have the same issue with your other account
With some help from the Linux Mint forum the problem is solved. In /etc/passwd some accounts did not have a default shell specified. Adding that solved the problem.
Thanks for pointing me in the right direction!
You will need google cardboard or some other VR headset.
This project is built on top of Deploy Linux. It uses SDL Xserver as well as a custom x11 compositor for VR graphics
To install do the following:
(Install base)
1: install openSuSE 13.2 with "Linux Deploy"
1.1: Installation type: FIle
1.2: Desktop Environment: LXDE
1.3: X Server2: /usr/sbin/sshd (start ssh)
3: Run: zypper in pango* (this will fix the issue with text being all boxes [])
At this point you should have a working SuSE install
4: Download the project https://bitbucket.org/ruapotato/vrsuse.git
5: Install python-xpyb-1.3.1-4.fc22.armv7hl.rpm (zypper in /path/to/vrlinux/python-xpyb-1.3.1-4.fc22.armv7hl.rpm)
6: Run: sed -i -e 's/RECTANGLE/xproto.RECTANGLE/g' /usr/lib/python2.7/site-packages/xcb/damage.py
Now we should be able to run the project
In a terminal run:
(With xserver sdl open)
7: source vrlinux/display.sh
8: lxsession &
9: vrlinux/pycompmgr &
OTG works alternatively you can use synergyc -f HOSTCOMPUTER for mouse/keyboard input

The primary purposes of Android are to create an open software platform available for carriers, OEMs, and developers to make their innovative ideas a reality and to introduce a successful, real-world product that improves the mobile experience for users.The result is a full, production-quality consumer product with source code open for customization and porting.
So basically Android Allows to customize the things you like and make new things without any Restrictions. Cool isn’t it?
What is Android ROM ?
The Android ROM is the Android operating system. This is the User interface (Sense UI in HTC phones) and the file system for maintaining contacts etc. It is composed of a Linux kernel and various add-ons to achieve specific functionality.
What does a Android Rom Contain ?
Basically a Android Rom Contains following main things :
· Kernel
· Bootloader
· Recovery
· Radio
· Framework
· Apps
· core
· android-runtime,Etc
Some Basics About Above Terms
Kernel :
A kernel is critical component of the Android and all operating systems. It can be seen as a sort of bridge between the applications and the actual hardware of a device. Android devices use the Linux kernel, but it's not the exact same kernel other Linux-based operating systems use. There's a lot of Android specific code built in, and Google's Android kernel maintainers have their work cut out for them. OEMs have to contribute as well, because they need to develop hardware drivers for the parts they're using for the kernel version they're using. This is why it takes a while for independent Android developers and hackers to port new versions to older devices and get everything working. Drivers written to work with the Gingerbread kernel on a phone won't necessarily work with the Ice Cream Sandwich kernel. And that's important, because one of the kernel's main functions is to control the hardware. It's a whole lot of source code, with more options while building it than you can imagine, but in the end it's just the intermediary between the hardware and the software. So basically if any instruction is given to mobile it first gives the command to kernel for the particular task execution.
Bootloader :
The bootloader is code that is executed before any Operating System starts to run. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. Think of the bootloader as a security checkpoint for all those partitions. Because if you’re able to swap out what’s on those partitions, you’re able to break things if you don’t know what you’re doing. So basically it commands the kernel of your device to Boot the Device properly without any issues. So careful with bootloader since it can mess things very badly.
Recovery :
Recovery is defined in simple terms as a source of backup. Whenever your phone firmware is corrupted, the recovery does the job in helping you to restore or repair your faulty or buggy firmware into working condition. It is also used for flashing the Rom’s , kernel and many more things.
Radio
The lowest part of software layer is the radio: this is the very first thing that runs, just before the bootloader. It control all wireless communication like GSM Antenna, GPS etc.
What you’ll need
A relatively recent 64-bit computer (Linux, OS X, or Windows)(Virtual Machine will work as well) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
A decent internet connection & reliable electricity
Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.
Install the SDK
If you haven’t previously installed adb and fastboot, you can download them from Google. Extract it running:
Code:
unzip platform-tools-latest-linux.zip -d ~
Now you have to add adb and fastboot to your PATH. Open ~/.profile and add the following:
Code:
# add Android SDK platform tools to path
if [ -d "$HOME/platform-tools" ] ; then
PATH="$HOME/platform-tools:$PATH"
fi
Then, run source ~/.profile to update yur environment.
Install the build packages
Several packages are needed to build LineageOS. You can install these using your distribution’s package manager.
To build LineageOS, you’ll need:
bc bison build-essential curl flex g++-multilib gcc-multilib git gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc zip zlib1g-dev
For Ubuntu versions older than 16.04 (xenial), substitute:
libwxgtk3.0-dev → libwxgtk2.8-dev
Java
Different versions of LineageOS require different JDK (Java Development Kit) versions.
LineageOS 14.1: OpenJDK 1.8 (install openjdk-8-jdk)
LineageOS 11.0-13.0: OpenJDK 1.7 (install openjdk-7-jdk)*
https://askubuntu.com/questions/761127/how-do-i-install-openjdk-7-on-ubuntu-16-04-or-higher
Create the directories
You’ll need to set up some directories in your build environment.
To create them:
Code:
mkdir -p ~/bin
mkdir -p ~/android/lineage
Install the repo command
Enter the following to download the repo binary and make it executable (runnable):
Code:
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
Put the ~/bin directory in your path of execution
In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing):
Code:
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
Then, run source ~/.profile to update your environment.
Initialize the LineageOS source repository
Code:
cd ~/android/lineage
repo init -u https://github.com/LineageOS/android.git -b cm-14.1
Download the source code
Code:
repo sync -c -f --force-sync --no-clone-bundle --no-tags --optimized-fetch --prune
Prepare the device-specific code
Code:
git clone https://github.com/SamarV-121/android_device_google_sprout4 -b cm-14.1 device/google/sprout4
git clone https://github.com/SamarV-121/android_device_google_sprout-common -b cm-14.1 device/google/sprout-common
git clone https://github.com/TheMuppets/proprietary_vendor_google -b cm-14.1 vendor/google
git clone https://github.com/SamarV-121/android_kernel_mediatek_sprout kernel/mediatek/sprout
Turn on caching to speed up build
Code:
export CCACHE_DIR=./.ccache
ccache -C
export USE_CCACHE=1
export CCACHE_COMPRESS=1
prebuilts/misc/linux-x86/ccache/ccache -M 50G
Configure jack
Jack is the new Java compiler used when building LineageOS 14.1. It is known to run out of memory - a simple fix is to run this command:
Code:
export ANDROID_JACK_VM_ARGS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4G"
Make Clean Build
Code:
make clean && make clobber
Initialize the build command
Code:
source build/envsetup.sh
Start Build
Code:
croot
brunch sprout4
