Interessante onderwerpen tijdens jaarcongres Topsector Logistiek

Vrijdag 22 april was het jaarlijkse congres van de topsector logistiek. De Amsterdam Arena was een prettige omgeving voor de plenaire sessies. Ook op het ‘experience plein’ waren verschillende sessies, waaronder van KPN over de uitrol van hun Low Power Long Range netwerk voor Internet of Things toepassingen. Wij waren natuurlijk blij dat KPN ons product Babbler als voorbeeld gebruikten.

The Hitchhiker’s Guide to Android functional testing

Android™ development and testing go hand in hand. When it comes to automated functional testing there are plenty of frameworks out there. At this years DroidconNL (23 – 25 November) Wiebe Elsinga & Ali Derbane will take the audience on a journey into several testing frameworks to use for Android functional testing.

Wiebe ElsingaAli Derbane

During their interactive session Wiebe and Ali will be presenting a fine selection that could help you decide what to use in your next project. Some of the frameworks they will talk about are Robotium, Robolectric, UIAutomator, Calabash, Selendroid and Espresso. And since DroidconNL is a developer conference there will be code as well!

Expanding your horizons using expansion files for Android

If you came to this page you probably scanned the QR code from the presentation that I did at droidconNL 2012 in Amsterdam. Or perhaps because you are interested in using expansion files for Android. Maybe the almighty Google even brought you here.

No matter how you got here, at my presentation I promised that I would provide you with source code and the presentation itself. The presentation and source code should be able to help you to get your Android application to use expansion files.

On top of that I will provide you with interesting reads that are definitely worth a look. So here goes:

  1. The source code – ExpandingHorizons
  2. The presentation – Expanding your horizons using expansion files
  3. Application in Google Play Store is incompatible for some “compatible” devices‘ – A blog post about why my app wouldn’t show up in the Google Play Store. The reason we started using expansion files
  4. Android developer page about expansion files

Thank you all for being interested and reading about these important matters! Feel free to leave a comment. I will gladly help you to expand your horizons!

Droidcon NL, an impression

It’s been a wonderful and exciting two days of enjoying the first ever Droidcon in the Netherlands. Not only did I talk to a lot of people about the DutchAUG, I also had the chance to give a presentation about “Prototyping your Android application”. Let me give you some of the highlights of droidconNL.

Introduction DutchAUG

Before the keynote was given, Johan Pelgrim (@jowipe), announced the formation of the Dutch Android User group. Besides the fact that I’m co-organizer, it’s important to join this group because of the power that a community can give to an individual..

Nick Butcher (Google)

Nick Butcher (@crafty) is an Android Developer Advocate, working at Google’s London office. He reminded us, Android Developers, that the time of creating wonderful Android apps is over, they need to be awesome. During his opening keynote and while talking about ICS, he gave a demo (Source: stevechippy) about Android Beam, and it worked (always exiting, a live demo).

Jens Mücke (Xing)

Jens Mücke (@jensmuecke) is a Senior Software Engineer at XING. He gave an inside view on how to become a Mobile company. I must say, not all points mentioned I can concur, but it’s always interesting to hear other companies talk about their strategy.


Novoda (@novoda) is an Android consultancy company based in London. Presenters Jamie McDonald, Luigi Agosti, Carl-Gustaf Harroch and Gonçalo Silva gave a talk about using Continuous Integration. It’s funny to see that they have the same setup as we, ItudeMobile, use. I must thank them because they helped me with one problem I had with Jenkins.


And than it was my turn to talk about prototyping. Thanks everybody for attending my talk.

Christine Karman

Christine Karman (@Xtien) is a Senior Software Engineer. She described, by way of clear code examples the use of RoboGuice. Great presentation.

Richard Hyndman

Richard Hyndman (@geekyouup) also an Android Developer Advocate, working at Google’s London office. He took the audience on a journey. Starting at the beginning of this year, telling how well Android is doing, until what the future holds for Android.


For the first ever droidcon in Amsterdam, they have done their best to make a good first impression. Some tweaking still needs to be done, but will be there next year. For enyone that’s interested in my talk, here’s my presentation
