Great write up on Loaders by +Ian Lake
 
Making loading data lifecycle aware with Loaders
Pro-tip by +Ian Lake

Screen rotations or other configuration changes shouldn’t interrupt loading data for your UI or throw away the data you’ve already loaded. Loaders solve this problem by surviving configuration changes yet are automatically cleaned up when their associated Activity or Fragment is permanently destroyed, giving you the data loading lifecycle you really want: when you have data to show.

Check out our blog post (https://goo.gl/EhSPni) and the code samples included within for some examples on how you can load any type of data with the Loader framework.

On Thursday February 11th you can sharpen your coding skills by teaming up with somebody else, choose a programming language and solve whatever programming challenge you will be presented with by Google. Sounds like a fun challenge? It is.

Note There are no specific Android coding skills required. If your go-to language is Go or Scala, Java, Ruby or what have you you can enter this competition.

Please help us spread the word by informing your colleagues, class mates or teacher about this challenge!

More information and sign-up at http://g.co/hashcode

#io16 will not be held at the Moscone Center this year, but near Google in Mountain View... They'll cap it off at a much lower attendee number then I guess. I can't imagine 5K people wandering about Castro street in the evenings... Better book your hotel room like... right now if you want a nearby place to crash.
 
Exciting news: we’re only 18 weeks away from Google I/O! 2016 is going to be a special year for us -- we held our first developer day 10 years ago at the Googleplex. To celebrate our 10th anniversary of developer gatherings, we’ll be hosting I/O in our backyard at the Shoreline Amphitheatre in Mountain View, CA from May 18th - 20th. We’ll have 3 full days together to dive deep into developer content, code labs, and more. If you can’t make it in person, you can still join us via I/O Live and through an I/O Extended event in your local community. Stay tuned to #io16 and +GoogleDevelopers in the coming weeks for more details.

Story
Tagline
Android Developer and initiator / organizer at The Dutch Android User Group
Introduction
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 (http://droidcon.nl), which was held on 22/23 in Amsterdam, The Netherlands.

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