We’re taking the wraps off of Android 7.1 Nougat, the latest version of the platform. You probably saw a sneak peek of it at last week’s event. It’s an incremental update based on Android 7.0 but includes great new features for consumers and developers. Later this month, we’ll be bringing you the Android 7.1 platform as an open Developer Preview, similar to what we did for Android 7.0. You’ll be able to test and build on the new platform, try the latest features, and give us your feedback. #AndroidN

+Q42 ... what a great bunch of people!
Awesomesauce! The supermen and -women of Q42 (+Q42) will be running around our #GDG #DevFest16 as Gold sponsor this year! Woohooo, thanks much for your continued support and enthusiasm for our DevFest Q42!

About Q42
Some people call us 'a tech-savvy internet agency'. Others just call us nerds. We call ourselves nerds too, to be honest. We just happen to really love good programming. But that's not the whole story. Computers are only interesting when they involve people. So even more than programming, we love programming web apps to not just be useful, but also friendly. The combination of technical complexity and end-user as a number one priority makes our work worthwhile. That makes Q42 truly a happy place for nerds.

Q42 bouwt aan apps, websites, connected devices, games, en VR. Dat doen we met z’n 64-en vanuit Amsterdam, Den Haag en Mountain View.

Albert Heijn IT Online... What a great team!
Great news! Albert Heijn IT Online is sponsoring the #GDG #DevFest After Party this year! Netherland's most innovative online retailer has a pretty cool IT department (go check out their jobs with the link below) and during the conference you'll get a chance to ask them all about it, while enjoying a cup of tasty Perla coffee or fresh mint tea at their booth.

Thanks Albert Heijn IT Online for making it possible that GDG DevFest The Netherlands not only is the greatest Google tech conference, but most of all free for the fourth year in a row!

About Albert Heijn IT Online
Albert Heijn IT Online offers customers new ways of buying groceries. Our digital formats offer customers extensive help in remembering and choosing their products. Customers are able to order their groceries online through and the Appie app, which are then delivered to their home or office.

In addition to this, customers have the possibility to obtain their groceries at an AH Pick Up Point. To be able to make all of this possible, an excellent IT department is of great importance. Are you the one who can make a difference in a trade that is catching up with online sales? We are looking for developers who want to shape this future with us.

Our department is growing rapidly. Our scrum teams have created our websites and logistics systems from scratch. Innovation is our goal: every other week software is brought live.

The best thing about working for Albert Heijn IT Online is that products, made by a scrum team, have a visible impact on our customers as well as our business. IT is one of the main pillars of growth in food-retail: as a result IT is not a precondition for Albert Heijn but a core business. Visit for more information.

Good to hear! Maybe you'll even meet my sister there. Or maybe she ends up in a completely different part of the company; I assume it's a big place.

Independent Android Developer and founder of The Dutch Android User Group
I've been programming since 1995. Java mostly and Java EE to be more exact. 

Since 2010 I've fallen in love with Android and the whole mobile opportunity. Fortunately I'm currently filling in a Mobile Software Engineer role at VX Company doing Android and a little iOS on the side.

Besides that I'm running a small business under the name Codestone, doing web- and mobile app development projects for small- to medium businesses and of course to host my own pet-projects.

I was an executive committee member for the barcamp and conference speakers at the first droidconNL conference (, which was held on 22/23 in Amsterdam, The Netherlands.

I am the initiator and organizer at The Dutch Android User Group ( A group of enthousiastic Android professionals and hobbyists which regularly meet to share knowledge and simply have fun and share stories on Android.
