Project Information

Skylight1 is an open source Java mobile projects framework and collection of Android applications and demos. This group started in Feb 2009 as part of the NYCJava Java User Group with the revenue from the project's initial applications going to the NYPC Users Group, a 501c3 educational non-profit. Our first project, "Balance the Beer" had over 450K downloads.

This project is also affiliated with the NYC GDG (Google Developer Group) and the New York Android Developers Meetup [ (join those to get meeting notifications)

To join please come to a public meeting first (listed on NYC-GDG Meetup calendar) then request membership here:


We have several ongoing projects (including Android Wear and Google Glass) and are open to additional ideas/members. We meet weekly (except during holidays). Come prepared to code with laptop - all levels welcome but this is hands on. We now have github and a private g+ community group.

Usually this is not a lecture oriented group but on occasion we do have presentations. Starting in January, we will be working alongside a weekly free Android course sponsored by Google/Udacity/NYC-GDG. If interested fill in this form: (this is a %100 discount of the listed course:

One recent Glass project was created in support of and supported Android Wear as well. Another is a recent submission to NYCBigApps Challenge called,|WearAbouts


Older Android Projects:

NENY (New Eats New York) - launched at NYCBigApps 2013

Seven Wonders: updated for Google TV: SevenWonders and it also now works on Google Glass if you build it and install via adb (or you can download the apk here: )

If you are a user of one our applications on the Android Market please see the UserGuide for submitting bugs, feature requests and requesting help. If you're a developer see DeveloperGuide.

The 'NYC Events' application was a NYC Big App Challenge entry in 2009, thanks to all who voted!

Previous News:

The official OHNY (Open House New York) Weekend Android Application is available on the market. note: art work used by permission, copyright by

Live wallpaper application "Fingerprint Live Wallpaper" avail under demos and Market (2.0+ only)

We developed and released (in 1 day, Dec 30-31, 2009) "Toast" as a result of not finding an equivalent of the "Clink-Clink" iPhone app on the Android Market - and just in time for New Years Eve.

We released 'NYC Events' on the Android Market in Dec 2009. This lists NYC Parks, Art and Music events based on data provided by We submitted to the challenge.

We launched our first app, a game based on the framework to the Android Market in late Sept 2009. It's called 'Balance the Beer' and currently is approaching 250K downloads and reaching #31 under casual games and featured briefly on the Google market website. Please give it a good rating on the market ;-)


Current ongoing large projects: the Places and Events (P&E) framework and Seven Wonders (7W), a 3D OpenGL game. To participate, stop by a NYC Java Meetup meeting or visit for more info.
