The document is about a DroidCon Train workshop on February 7th, 2014 hosted by GDG L-Ab. The workshop covered using context such as location and activity recognition to tailor apps. Attendees were introduced to tools from Google Play Services for understanding user context and coding examples were provided for activity recognition and geofencing.
