With the YouTube WatchMe for Android project, Google is looking to help third-party developers integrate live streaming directly into their apps.
It’s an open source project available on GitHub, harnessing the YouTube Data API v3, YouTube Live Streaming API, Google Play Services and Plus API. It basically offers a template app that you can adjust for your own needs, and you can read more about how to go about setting things up here.
Though Google still classes the app as experimental, the same live broadcasting capabilities are evident in existing third-party apps such as Live on YouTube by Sony Xperia. By making it available on GitHub, anyone can now use it.
