Cuttlefish Getting Started

Try Cuttlefish

  1. Make sure virtualization with KVM is available.

     grep -c -w "vmx\|svm" /proc/cpuinfo

    This should return a non-zero value. If running on a cloud machine, this may take cloud-vendor-specific steps to enable. For Google Compute Engine specifically, see the GCE guide.

ARM specific steps:

  • When running on an ARM machine, the most direct way is to check for the existence of /dev/kvm. Note that this method can also be used to confirm support of KVM on any environment.
  • Before proceeding to the next step, please first follow the guide to adjust APT sources.

  1. Download, build, and install the host debian package:

    sudo apt install -y git devscripts config-package-dev debhelper-compat
git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish
debuild -i -us -uc -b
sudo dpkg -i ../cuttlefish-common_*_*64.deb || sudo apt-get install -f
sudo usermod -aG kvm,cvdnetwork $USER
sudo reboot

    The reboot will trigger installing additional kernel modules and applying udev rules.

  2. Go to http://ci.android.com/

  3. Enter a branch name. Start with aosp-master if you don‘t know what you’re looking for

  4. Navigate to aosp_cf_x86_64_phone and click on userdebug for the latest build

  5. Click on Artifacts

  6. Scroll down to the OTA images. These packages look like aosp_cf_x86_64_phone-img-xxxxxx.zip -- it will always have img in the name. Download this file

  7. Scroll down to cvd-host_package.tar.gz. You should always download a host package from the same build as your images.

  8. On your local system, combine the packages:

    mkdir cf
cd cf
tar xvf /path/to/cvd-host_package.tar.gz
unzip /path/to/aosp_cf_x86_64_phone-img-xxxxxx.zip

  9. Launch cuttlefish with:

$ HOME=$PWD ./bin/launch_cvd

  1. Stop cuttlefish with:

$ HOME=$PWD ./bin/stop_cvd

Debug Cuttlefish

You can use adb to debug it, just like a physical device:

$ ./bin/adb -e shell

Launch Viewer (WebRTC)

When launching with ---start_webrtc (the default), you can see a list of all available devices at https://localhost:8443 . For more information, see the WebRTC on Cuttlefish documentation.
