croupier: Croupier with 2+ devices The Makefile setup has been upgraded (accompanied by README.md) such that we can run Croupier on multiple Android devices at the same time. To further prove this, the devices join a syncgroup together and share each other's settings. These settings are shown (in an ugly manner) as CroupierProfileComponents. There are some caveats though: - must change Mojo to expose some ports as environment variables - must start the first device (syncgroup) early enough - that same first device's app will likely crash after restarting the app, so it must be fully uninstalled. - must connect the devices in a specific order and use ANDROID=1 (or 2, 3, ...) to reference them. (We parse adb logcat in order to get the device id.) These Syncgroups never forget devices (at this point in time), so this is not necessarily equivalent to Discovery. However, it is close enough that we can continue onto the Invite Players and Arrange Players screens. Change-Id: I8f940930fddcbb81fe7df408c3bacc84cd61eb54
Croupier is a Vanadium demo app of a general card playing game for multiple devices. The app combines Syncbase with Mojo and Flutter and in the near future, will also demonstrate P2P discovery and Syncgroup formation.
Croupier's primary card game is Hearts, but it is only available in single-device form. More games will be added in the future.
In order to run the program, it is recommended to use Android devices. (Support for desktop is deprecated and will be removed soon.)
Currently, development is heavily tied to an existing installation of Mojo. Please ensure that your Mojo checkout is located at $MOJO_DIR and has built out/android_Debug. Instructions are available here.
Note: Currently, in order to run on multiple devices at once, we modified a file in Mojo: mojo/devtools/common/devtoolslib/shell_arguments.py Related issue for multiple Android support: https://github.com/domokit/mojo/issues/470
Use the os library to read environment variables and use defaults otherwise.

Flutter depends on a relatively new version of the Dart SDK. Therefore, please ensure that you have installed the following version or greater:
Dart VM version: 1.13.0-dev.3.1 (Thu Sep 17 10:54:54 2015) on "linux_x64"
If you are unsure what version you are on, use dart --version.
To install Dart, visit their download page. You may need to manually download a specific version of Dart. If so, visit their archives for exact downloads.
A Vanadium installation is expected, since Croupier also depends on the release/projects/mojo/syncbase project.
Begin by creating your credentials. These are used to determine who can access your Syncbase instance. Note that running the following command will pop-up the standard principal seekblessings tab in order to obtain your approval to use OAuth.
make creds
Any time you clean the credentials, you will need to obtain fresh credentials.
If you have more than 1 device plugged into the computer, you will need to specify which device to use. adb devices will tell you the order of your devices.
It is highly recommended that you mark/remember the order of the devices; it is the same as the order they were plugged into the computer/workstation.
For later devices, instead of ANDROID=1 use 2, 3, 4, etc.
Note: Running Croupier on multiple Android devices simultaneously is still a work-in-progress. The workaround is to launch Croupier on a single device at a time.
Note: This example currently relies on a mount table on the local network at 192.168.86.254:8101. This may be changed to the global mount table at a later time. https://github.com/vanadium/issues/issues/782
Start Croupier on your USB-debugging enabled Android device.
ANDROID=1 make start
Alternatively, use a different integer. Since the first device creates a syncgroup, it is recommended that you wait a short duration before starting up any other devices.
On your Android device, go to the Apps that you downloaded and Uninstall Mojo Shell from there. This cleanup step is important for when Syncbase is in a bad state.
Note: Due to issues with Syncgroup creation, an app that creates a syncgroup will not be able to start a second time, so you must delete the mojo shell after each run. Fixing this is a high priority.
Due to some issues with mojo_shell, you may occasionally fail to start the program due to a used port. Follow the error's instructions and try again.
Between builds of Mojo and Syncbase, you may wish to clean the app up.
ANDROID=1 make clean
You can also clean credentials instead:
ANDROID=1 make clean-creds
Don't forget to do make creds to rebuild them.
Lastly, you can also clear out the pub packages:
make veryclean
