Adds support for device_states custom actions.

This allows specifying hardware values for inputs used by the
DeviceStateManager, such as lid switch state and hinge sensor value.

Note: currently only lid switch state is supported.

Bug: 181664980
Test: Use the closed/opened buttons to interact with the device.
      Observe lid switch events via `getevent -lt`.
      Observe device state via `dumpsys device_state`, note that
      device state is not 'overridden' (like it was prior to this
      change).
Test: Add more states (including hinge sensor values) to the device
      state custom actions. Observe multiple buttons and console.log
      messages as the device cycles through states.

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!
