These are the submissions we got through the Call for Papers time period.
As we wanted to give all the speakers a chance to present their Idea, we decided *not* to start a voting!

See what's next: A Mobile App Called Fjutur

"Fjutur helps you to see what's next by arranging your Google Calendar entries on a time line and presenting alternative routing  directions from your current position to these upcoming appointments. The App is still in development but already very helpful. 

The vision behind Fjutur is an valuable tool to simplify your day to day planning and scheduling by rendering a vast number of  information sources (Google Directions, Public Transportation Services, weather forecasts, battery lifetime, etc.) into a well  perceivable and interactive depiction."

The architecture of LiquidFeedback - Interactive Democracy

"LiquidFeedback is an online system for discussing and voting on proposals. It combines concepts of a non-moderated, self-organized discussion process (quantified, constructive feedback) and liquid 
democracy (delegated or proxy voting). Following the idea of interactive democracy LiquidFeedback introduces a new 
communication channel between voters and representatives (in this case members and board members), delivers reliable 
results about what the members want and can be used for information, suggestion, or directive depending on the organizational 
needs and the national legislation.
LiquidFeedback has been developed by the Public Software Group in Berlin, Germany. All the experience we have gained over the past months shows people participate if they think it makes sense and 
representatives at least acknowledge the will of the participants rather than arguing with silent majorities."

Eclipse DataBinding for Android

I'm a fan of the Eclipse DataBinding Framework 
and in the last weeks in my first project on Android 
I tried to port my DataBinding sample application 
which is running already with SWT and Swing to Android.
The result of the memory footprint and performance costs were surprisingly well
so I want to present it to the Android community. 
(I will public the sources on github in the next days.)

Native Mobile Applications with the Google Web Toolkit(GWT)

Hello there,
I m Alain Ekambi. A software Engineer located in Munich/Germany. I m also an open source developer and author of the project  located at 
I d love to talk about writing  native mobile applications for Android and IOs using the Google Web Toolkit(GWT) and the   Appcelerator Titanium runtime( The idea behind it is to use ONE java code based on deploy to  android and IOS. 
It would be a huge honor to present this at the GDD.

Write Cross-Platform Web-Apps in Java

It's possible to write apps in Java and HTML/CSS with the power of Horaz. Horaz is a cross-platform framework for writing mobile applications, that run under the main mobile platforms (Android, iOS, Windows Phone). It bases on GWT,  Phonegap and jQuery mobile.

In this session, I'll introduce into developing with Horaz, from setting up for IDE until running a HelloWorld app on a Android phone  and a iPhone.

A Tiling Window Manager for Android Tablets

I am developing a Tiling Window Manager for Android tablets that allows working with multiple web applications simultaneously.  You no longer have to switch tabs or applications when you want to take a quick note or look up a date in your calendar. You simply open a second window.

I will talk about why using multiple windows makes sense on an Android tablet, why I have chosen to focus on web applications  for my project and how multi-touch gestures can make window management effortless and fluid.
