Android Development with Kotlin – Jake Wharton

Kotlin is a relatively new programming language that runs on the JVM. It features some new enhancements that doesn’t exist in Java (6) and has the potential to make Android development much better. Null safety, Lambdas, Higher-Order Functions and Extension Methods to name a few. As always Jake Wharton from Square with a great 30 minutes video to bring you up to speed with why Kotlin is awesome and how to use it. To read Jake’s full analysis (with real Byte Code) use this: https://docs.google.com/document/d/1ReS3ep-hjxWA8kZi0YqDbEhCqTt29hG8P44aA9W0DM8/edit?hl=en&forcehl=1

Help developers with custom Lint rules

I’ve been waiting for someone to write on custom Lint rules for a while now. This post shows how to build custom Lint rules. Apparently it’s easy and there are companies that are already doing that as a method to enforce coding standards. I’m guessing that this will become a standard in a few years.
