Cuttlefish Getting Started

Try Cuttlefish

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.

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.

Go to http://ci.android.com/
Enter a branch name. Start with aosp-master if you don't know what you're looking for
Navigate to aosp_cf_x86_64_phone and click on userdebug for the latest build
Click on Artifacts
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
Scroll down to cvd-host_package.tar.gz. You should always download a host package from the same build as your images.

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

Launch cuttlefish with:

$ HOME=$PWD ./bin/launch_cvd

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.

Launch Viewer (VNC)

When launching with --start_vnc_server=true , 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!
