Kotlin

While Android supports most Java language features, it doesn’t support every API that Java provides. On the other hand, Kotlin multiplatform only allows sharing code across all targets (commonMain), not a subset of targets (commonJvm).

Short, powerful post on how to test the release version of libraries directly within a project without having to deploy them to Maven first. As a bonus, there will also be an open-source example showcasing all of this in action.

Ever had a build failure while integrating an SDK? Wonder how you can avoid your SDK customers having dependency conflicts? How many transitive dependencies should your SDK have?

With modularization being all the hype, should you also modularize an SDK? Are fat aar files really needed? And how do you prevent internal APIs from being exposed on your public interface?

Having switched to Android SDK development over the past year, I’ve run into quite a few interesting and unexpected challenges. So how does library development differ from app development?

A great way to make your library easier to use it to generate code documentation for its public interface. The default way to do this in Kotlin is to generate KDoc using the official Dokka plugin.

Learning from analyzing code is one of the greatest ways to improve your skills. Can you spot the mistakes in the tests below? This post brings a fun little quiz for both testing gurus as novices, with a deep dive into the how and why of awesome tests.

Java interop is one of the best features of the Kotlin language, yet sometimes this also can cause unforeseen issues… Puzzle # Disclaimer, the example below is a consequence of legacy code and only serves to demonstrate a Kotlin puzzler.

Kotlin is an incredibly enjoyable, concise and powerful programming language. Yet sometimes also a bit confusing… Puzzle # Have a look at the simple class below.

This isn’t another post about the benefits of using Kotlin. Hell, I’m not even going to cover any of its language features. Nor will I try to convince you to make the switch.
