ro.com.android.dataroaming in device.mk is optional

The final value for the system property is in device_vendor.mk

Change the setting in device.mk as optional to explicitly mark that
the value there can be overridden. This also is in preparation for
I9c073a21c8257987cf2378012cadaeeeb698a4fb where duplicated
(non-optional) sysprops is prohibited.

So you want to try cuttlefish?

  1. 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
  1. Go to http://ci.android.com/
  2. Enter a branch name. Start with aosp-master if you don‘t know what you’re looking for
  3. Navigate to aosp_cf_x86_phone and click on userdebug for the latest build
  4. Click on Artifacts
  5. 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
  6. Scroll down to cvd-host_package.tar.gz. You should always download a host package from the same build as your images.
  7. 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
  1. Launch cuttlefish with:

    $ HOME=$PWD ./bin/launch_cvd

  2. Stop cuttlefish with:

$ HOME=$PWD ./bin/stop_cvd

So you want to debug cuttlefish?

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

$ ./bin/adb -e shell

So you want to see cuttlefish?

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!
