droidcon Berlin starts off with a barcamp on Wednesday, followed by two conference days and finally it features a one-day hackathon on June 6, 2015.

The droidcon hackathon is your chance of putting into practice what you have learned at the conference, and maybe form some lasting partnerships by bringing your ideas to life! You’ll be joining forces with other passionate Android developers to create something unique – or even win a prize provided by our hackathon partners. This hack will attract some of the most talented coders and creative experts!

How can you join the hackathon?

Register for a free hackathon ticket by the 5th of June!

Even if you have already bought a ticket for droidcon Berlin, we need a separate registration for the hackathon in order to take care of the catering, program and facilities.


08:00 – 09:00: Doors open/Breakfast

09:00 – 10:00: Presentations of projects/group formation

10:00 – 17:50: Hacking time

17:50:                Submission deadline

18:00 – 18:45: Group presentations

18:45 – 19:15: Presentation ceremony (see prices below)

followed by a public viewing of the Champions League Final FC Barcelona – Juventus Turin (Kick-off: 20:45)

A full catering will be provided for the whole hackathon – huge thanks to our hackathon partner Delivery Hero! Better come early and get some breakfast before the hackathon starts off.


What are the challenges?

We are happy to introduce you to the challenges of this year's droidcon hackathon:

1. "Build and program automotive robots"

In this project, you can build your own automotive robots with LEGO Mindstorms. The Mindstorms system provides not only LEGO bricks, but also different actors and sensors and a programmable brick to create models which illustrate real life use-cases in connected or (semi-)autonomous cars scenarios. At the beginning you can build some simple vehicles using standard building instructions or using your mechanical engineering skills to create the model you need.

After this building phase we will dive into the programming of the vehicles. You can create cars which collect data while driving around and cars which communicate with each other (car2car), with infrastructure (car2x) or with your android device. You can even create vehicles with (semi-)autonomous abilities. Bring any idea from the connected cars world you want to realize and try to bring it to life with the parts provided and in the time frame you have during the hackathon. Beside a lot of building material and printed documentations we will have an expert on site who will give you some individual introduction how to program the robots using Java.

Please check out http://www.lejos.org/ for documentation of the java programming abilities of the mindstorms system in preparation to this hackathon (we will only have EV3 and NXT systems on site). Please bring also your computer with your preferred and ideally prepared programming environment. There's a limited number of spots available for this project, so please come early and sign-up on Saturday.

2. "Data Science using San Francisco's cab fleet"

It’s the same problem in Berlin, San Francisco and everywhere else in the world: Cab drivers are cruising through the city for the whole day just to find customers. What if you have access to all the information of where cab drivers find customers, where they bring them, and where empty cabs are driving around?

Imaging showing the best spot where to catch an empty cab - or analyze historical data and make a prediction of where cab drivers should go to find customers!

This project will provide you will all necessary data in an easily consumable API and even more: We will provide you with an example app that gets you started using our API and visualizing your own algorithm. But you're also welcome to hack directly with the API and surprise us with your creativity.

3. "Making Devices Smart: Integrating The WunderBar with Dumb Devices"

This is all about high-speed innovation! In times where technology is developing rapidly and being connected is a must, our old dumb devices are starting to lose out to new smarter ones that enable us to have better control over our activities and the world around us. However, smart devices can be much more expensive than traditional ones.

What if we could make our old dumb devices smart and affordable, or create better smart options? We challenge you to make the difference by transforming dumb devices into smart ones, or making existing smart devices even smarter, by empowering them with the WunderBar and the relayr cloud.

In the words of Kevin Kelly, editor at Wired: "(AI) will enliven inert objects, much as electricity did more than a century ago. Everything that we formerly electrified we will now cognitize."

Be one of the first to do so by using the WunderBar and the relayr platform.

4. Beacon Inside - Bluetooth Low Energy Beacons

1B+ smartphone users rely on satellite-based GPS for location-based services but GPS does not work indoors and leads to imprecise results and a high battery drain. In today's mobile world indoor location services are nearly non-existent but people spend 90% of their time inside buildings! It's time to get started with Bluetooth Low Energy beacons. These radio transmitters are broadcasting a position to nearby smartphone, in indoor and outdoor environments.

We will provide Beaconinside beacons and a sample proximity project for Android to quickly get started. Now it’s up to you to hack interactive tour guides, real-time heatmaps, indoor navigation for visually impaired, location-aware home and IoT solutions, indoor games or contextual user experiences improving everyday life.

5. Get your app into the car using the Pioneer Smart Mirror

Pioneer provides their recently announced Rearview Mirror Telematics Unit which was showcased for the very first time at the CES in Las Vegas in January 2015. These Smart Mirrors are yet not available in retail, hence it’s a very unique opportunity to do developments in such an early stage. The Smart Mirrors are equipped with:
- 4G connectivity
- front facing camera with tan extra wide field of view
- rear camera
- Accelerometer
- Microphone
- and others
This device is the perfect platform to bring your Android app into any car.
