Snap for 5590969 from 3abb5e77ae685e7ee7fafdd452bf52ff8bb53675 to sdk-release Change-Id: Ib377d3ed6286dc61edea2a53a60f0adda6a06cb4
adeb (also known as androdeb) provides a powerful Linux shell environment where one can run popular and mainstream Linux tracing, compiling, editing and other development tools on an existing Android device. All the commands typically available on a modern Linux system are supported in adeb.
Powerful development environment with all tools ready to go (editors, compilers, tracers, perl/python etc) for your on-device development.
No more cross-compiler needed: Because it comes with gcc and clang, one can build target packages natively without needing to do any cross compilation. We even ship git, and have support to run apt-get to get any missing development packages from the web.
Using these one can run popular tools such as BCC that are difficult to run in an Android environment due to lack of packages, dependencies and cross-compilation needed for their operation. Check BCC on Android using adeb for more information on that.
No more crippled tools: Its often a theme to build a static binary with features disabled, because you couldn‘t cross-compile the feature’s dependencies. One classic example is perf. However, thanks to adeb, we can build perf natively on device without having to cripple it.
Target: An ARM64 android N or later device which has “adb root” supported. Typically this is a build in a userdebug configuration. Device should have atleast 2 GB free space in the data partition. If you would like to use other architectures, see the Other Architectures section.
Host: A machine running recent Ubuntu or Debian, with 4GB of memory and 4GB free space. Host needs debootstrap and qemu-debootstrap packages. To install it, run
sudo apt-get install qemu-user-static debootstrap. Other distributions may work but they are not tested.
cd adeb # Add some short cuts: sudo ln -s $(pwd)/adeb /usr/bin/adeb # Cached image downloads result in a huge speed-up. These are automatic if you # cloned the repository using git. However, if you downloaded the repository # as a zip file (or you want to host images elsewere), you could set the # ADEB_REPO_URL environment variable in your bashrc file. # Disclaimer: Google is not liable for the below URL and this # is just an example. export ADEB_REPO_URL="github.com/joelagnel/adeb/"
The previous command only downloads and installs the base image. Instead if you want to download and install the full image, do:
adeb prepare --full
CTRL + Dand you will exit out of the shell. To remove adeb from the device, run:
If you have multiple devices connected, please add
-s <serialnumber>. Serial numbers of all devices connected can be obtained by
adeb prepare --kernelsrc /path/to/kernel-source
If you need to put kernel sources for an existing install, run:
adeb prepare --kernelsrc /path/to/kernel-source --skip-install
Note: The kernel sources should have been built (atleast build should have started).
The adeb fs will be prepared locally by downloading packages as needed:
adeb prepare --build
This is unlike the default behavior, where the adeb rootfs is itself pulled from the web.
If you wish to do a full build (that is locally prepare a rootfs with all packages, including bcc, then do):
adeb prepare --full --build
adeb prepare --build --kernelsrc /path/to/kernel-source/
adeb prepare --build --bcc --kernelsrc /path/to/kernel-source/
Note: BCC is built from source. Also
--kernelsrc is recommended for tools to function unless device has them already.
adeb prepare --buildtar /path/
After device is prepared, it will extract the root fs from it and store it as a tar archive at
/path/adeb-fs.tgz. This can be used later.
adeb prepare --archive /path/adeb-fs.tgz
adeb prepare --build-image /path/to/image.img
This can then be passed to Qemu as -hda. Note: This option doesn't need a device connected.
By default adeb assumes the target Android device is based on ARM64 processor architecture. For other architectures, use the --arch option. For example for x86_64 architecture, run:
adeb prepare --build --arch amd64 --bcc --kernelsrc /path/to/kernel-source/
Note: The --download option ignores the --arch flag. This is because we only provide pre-built filesystems for ARM64 at the moment.
apt-get install g++fails.
adeb shell apt-get update after the
adeb prepare stage.
