Transit for Android Wear was created for a hackathon at the Google Developer Group Düsseldorf.
It is meant as an add-on to Transit Android, which will be released in the coming months, to displays notifications of train or bus departure times on your Android wearable in your vicinity.
In order to run the sample, you'll need access to the Preview Wear SDK.
This is just a sample code and meant for educational purposes only. It doesn't fetch live departure times nor does it use your real location, in order to make debugging easier.
