Add a factory-reset-protected block device.

This is unfortunately non-functional on the device without an
implementation the framework can use.

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.

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

    git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish
debuild -i -us -uc -b
sudo dpkg -i ../cuttlefish-common_*_amd64.deb || sudo apt-get install -f
sudo reboot

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

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

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

  5. Navigate to aosp_cf_x86_phone and click on userdebug for the latest build

  6. Click on Artifacts

  7. Scroll down to the OTA images. These packages look like aosp_cf_x86_phone-img-xxxxxx.zip -- it will always have img in the name. Download this file

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

  9. 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_phone-img-xxxxxx.zip

  10. 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

You can use the TightVNC JViewer. Once you have downloaded the TightVNC Java Viewer JAR in a ZIP archive, run it with

$ java -jar tightvnc-jviewer.jar -ScalingFactor=50 -Tunneling=no -host=localhost -port=6444

Click “Connect” and you should see a lock screen!
