If you've attended any Liferay Symposium, Solutions Forum, or Developer Conference in the last few years you've undoubtedly seen the companion mobile app that attendees can use to see up-to-date agendas, speaker info, session data, and a bunch of other features that enhance the attendee experience.
I'm happy to announce that the source code to this app (and its two server-side components here and here) is now available at GitHub and is waiting for you to check out (and developers to contribute!). The app is an example that showcases the real-world use of Liferay as a mobile data provider to a rich native app experience. It has been used at many of our events with thousands of attendees, speakers, sponsors, sessions, and more. Check out its documentation for details on how it works and how you as a mobile developer can also use it.
It takes advantage of several mobile features of the Liferay Platform, and there are many more for you to check out regardless of your mobile strategy (mobile developers and strategists won't want to miss next week's Developing Awesome Android Applications with Liferay Screens webcast!).
This app is not officially supported by Liferay, there is no official "release" and there is no one you can call to complain :) But you can contribute fixes, translations, or improvements! See the README for details.
