Google Developer Weekend Hack and Tell

Posted on November 18, 2011

The Google Developer Weekend started with a Berlin Hack and Tell Special Google Edition at C-Base.

Thanks to Deborah from http://9flats.com for the Pizza.

Here's a short list of the projects:

Friedger Muefke

http://open-accessories.com

Friedger showed how to modify google docs with google appscript and access data from a spreadsheet and send it to a blog.

Lean Engine

Mathias from lean engine showed how to cloud enable your mobile apps.

Stefan Wehrmeyer

Stefan presentedhttp://mapnificent.net, a layer over google maps which tells you what points in a city you can reach via public transport in a given time.

Stefan uses http://www.gtfs-data-exchange.com/ to get the timetables for public transport. Sadly the berlin transport organization BVG does not provide real time data.

wheelmap.org

whellmap.org is a map with wheelchair accessible places. The presenter showed how to work around the android sqlite limitations to work with lat/long positions.

Launchmode

Gonsala shode launchmode, an app to help visualize android activities.

xbounds.net

xbounds is a great hack to add screensharing to mobile devices.

andengine

Johannes presented how to use andengine together with Physics Editor. It's a simple way to add physics to your games (like collition detection). Just load an image of your level to Physics Editor and load the result to andengind.

komoot.de

Jonas and Jan talked about some design decisions for http://komoot.de an outdoor navigation and route planning app.

They dropped a local database on the mobile phones in support for a thin caching layer and now get all data from their servers.

Daniel Kurka

@dankurka showed m-gwt.com. It lets you programm gwt applications for mobile phones. The gwt programm is compiled to html5/css and runs via phone gap on your mobile phones
