Docker Project Tango Development Environment

This is an Android Studio development environment created for Google's Project Tango using Docker. I built this as a fast way to spin-up a Project Tango development environment for myself, but I am happy to integrate suggestions and improvements.

It was made to run on an Ubuntu 14.04 host, but should work under other versions of Linux and OSX (using XQuartz & Docker-Machine) without too much tweaking. I haven't used Windows much for Docker, so I can't really say how well it will work.

Note: You must have a Project Tango device to use this Docker Image. Google has not yet made a Project Tango emulator to use for development.

Setting Up the Docker Container

  1. Make sure you have Git, Docker, and Docker-Compose installed on your machine.
  2. Clone this repo: git clone git@github.com:toddsampson/project-tango-docker.git && cd project-tango-docker
  3. IMPORTANT: If your host computer user and group IDs aren't set to 1000, update the android-studio/Dockerfile to the correct values and use the build command instead of image in the docker-compose.yml.
  4. Run xhost + to allow the container to communicate with your host system's X server.
  5. If you don't have an AndroidStudioProjects folder on your host computer, create one. Then update /home/toddsampson/AndroidStudioProjects in docker-compose.yml with the path to your project folder; leaving everything after the ":" unchanged.
  6. Plug-in and turn-on your Project Tango device.
  7. Run docker-compose run android-studio which will setup the Docker Container and launch a Bash terminal.
  8. Run studio.sh to start Android Studio. Unless you need specific customizations, simply click Next a few times to begin installation of the SDK.
  9. During the SDK install the Project Tango device should show an Allow USB debugging alert. When it does, check the Always allow from this computer box and click OK.
  10. Wait for the SDK to finish installing and click Finish to complete setup.

Getting Started Using the Container

Once Android Studio has been setup, you can run through the Project Tango examples found in the Docker Container's /srv directory. We will walk through the /srv/tango-examples-c/hello-tango-jni-example as a quick getting-started.

  1. From the Android Studio launch screen select Import Project (Eclipse, ADT, Gradle, etc.)
  2. Select the /srv/tango-examples-c/hello-tango-jni-example folder and click OK
  3. You will likely get a number of messages about missing SDKs, built tools and plugins from Gradle. Each time, click the Install missing platform/build tools and sync project or Fix plugin version and sync project followed by Finish. After Gradle stops showing you these messages, usually three screens, proceed to the next step.
  4. Click on the word Project printed vertically on the left side of Android Studio.
  5. In the file window that appeared when clicking Project, double-click on Gradle Scripts. Then double-click on local.properties.
  6. In the local.properties file, add ndk.dir=/home/android/Android/android-ndk-r10e below the sdk.dir=... line and save the file. This will allow Gradle to know where to find the Android NDK.
  7. Press the green play button (Run App) in Android Studio. Select Google Project Tango Tablet Development Kit... under Choose a running device, check Use same device for future launches and click OK.
  8. The app should launch on your Project Tango device. If you receive a message to enable Motion Tracking, accept it. If not, press the home button on your Project Tango device and re-run step eight.
  9. If all went well you should be able to move your Project Tango device around and see the values being displayed in Android Studio via the Android Debugging Bridge (ADB). You are now ready to run through the rest of the examples or begin building your own application.
