Interesting post on functional-programming-inspired pattern matching technique using the visitor pattern in Java.

http://eng.wealthfront.com/2015/02/pattern-matching-in-java-with-visitor.html
I once read an essay—I cannot find it now—that talked about how learning a more advanced programming language can improve your coding even in a language that lacks those features because those language features are really way...

Awesome Window flag discovery: set the FLAG_SECURE flag on the Activity's Window to prevent screenshots from being taken.

Yup! I did the same, it was a 4-day trek. We got lucky with weather and it was sunny most of the time despite it being the rainy season.

Can't wait to watch this and learn some physics!
 
Somebody went to the movies . . . again.
Neil deGrasse Tyson @neiltyson 
- In #Interstellar: All leading characters, including McConaughey, Hathaway, Chastain, & Caine play a scientist or engineer.
- In #Interstellar: There’s a robot named KIPP. One of the Executive Producers, a physicist, is named Kip. I’m just saying.
- In #Interstellar: And in the real universe, strong gravitational fields measurably slow passage of time relative to others.
- GPS satellites, located farther from Earth’s center than we are, keep faster time than do our clocks on Earth’s surface.
- GPS Satellites are pre-corrected for General Relativity, allowing them to beam us the accurate time for Earth’s surface.
- In #Interstellar: Experience Einstein’s Relativity of Time as no other feature film has shown.
- In #Interstellar: Experience Einstein's Curvature of Space as no other feature film has shown.
- Relativity. Gravity. Quantum. Electrodynamics. Evolution. Each of these theories is true, whether or not you believe in them.
- In #Interstellar: The producers knew exactly how, why, & when you’d achieve zero-G in space.
- In #Interstellar: You observe great Tidal Waves from great Tidal Forces, of magnitude that orbiting a Black Hole might create
- In #Interstellar: You enter a 3-Dimensional portal in space. Yes, you can fall in from any direction. Yes, it’s a Worm Hole.
- In #Interstellar: They reprise the matched-rotation docking maneuver from "2001: A Space Odyssey," but they spin 100x faster.
- In #Interstellar: Of the leading characters (all of whom are scientists or engineers) half are women. Just an FYI.
- In #Interstellar: On another planet, around another star, in another part of the galaxy, two guys get into a fist fight.
- In #Interstellar, if you didn’t understand the physics, try Kip Thorne’s highly readable Book “The Science of Interstellar"
https://play.google.com/store/books/details/Kip_Thorne_The_Science_of_Interstellar?id=PbWYBAAAQBAJ&hl=en )
http://www.theguardian.com/science/2013/jun/21/kip-thorne-time-travel-scientist-film )
- In #Interstellar, if you didn’t understand the plot, there is no published book to help you.
- REMINDER: Never look to me for opinions on new films. All I do is highlight the science one might or might not find in them.
- In #Interstellar: They explore a planet near a Black Hole. Personally, I’d stay as far the hell away from BlackHoles as I can

My favorite feature of JVM-based language Kotlin: null is a first-class citizen. It has the most elegant solution over other JVM-based languages that I've seen (READ: Scala which requires you to wrap objects in an Option). Seems to be the right first step towards fixing the billion dollar (and counting) mistake.

Thanks for the write-up +Jake Wharton, really good stuff.

I've been seeing some great turnaround with poor reviews from users on Google Play simply by responding to users and addressing issues they report. Granted, I don't have thousands of users on my app but crafting an individualized response shows that you care about bringing a good experience to everyone.

Awesome tips to make Android development easier. I esp. like maven central search capabilities in the project structure dependencies tab.
 
Always pick up lots of dev tool tips from +Tor Norbye's sessions:

– Use the Android project structure for a simpler organization of your project and nice groupings  of resources e.g. seeing the different versions of dimens.xml for different resource qualifiers
– The Project Structure > Dependencies tab can search Maven Central for libs and add them to your build file.
– The layout editor lets you preview in RTL and offers a super easy Add RTL refactor to scan your whole project and fix RTL issues.
– The layout editor lets you set that you prefer the XML view
– The create emulator wizard now shows system images available to download with a handy link
– Use the new android.support.annotations.* to guard your int parameters e.g. use @LayoutRes to mark that an int param should be a layout resource id.  See https://developer.android.com/reference/android/support/annotation/IntDef.html for a good example of declaring your own acceptable values.

Good stuff.  #AndroidDev   #devoxx14

Introducing a new guide, “The Secrets to App Success on Google Play”

Publishing your app on Google Play is a good start, but it’s only the first step to building a sustainable app business. That’s why we’ve written “The Secrets to App Success on Google Play,” a detailed guide on the best practices and tools you can use to maximize the reach, retention, and revenue of your new app.

Get the guide now: http://goo.gl/dwT6FH

We’ll release the guide in more languages in the coming months and we’ll continue to update http://developers.android.com/distribute with best practices to help you distribute and monetize your app successfully. 

Once you’ve checked out the guide, we’d love to hear your feedback so we can continue to improve: http://goo.gl/kULrYR.
