This is a short article I’m writing in 2022 for my future self, because I keep forgetting the difference between these functions and their precise behavior. Maybe you’ll also find it useful! TL;DR for modern Kotlin (version 1.5 and later): % is the same as rem, mod is different %/rem will return 0 or a value with the…

We recently updated Jetnews to enhance its behavior across all mobile devices, both big and small. We’d like to take you through our design and development process so that you can learn the philosophy and associated implementation steps for building an application optimized for all screens with Jetpack Compose, including…

It’s sometimes nice to think about code in a vacuum. Perhaps that function you just wrote elegantly solves a problem, or some interface models the situation perfectly. You submit your modification, happy with the changes, introducing just enough complexity without causing any unintended side-effects. Unfortunately, we live in the real…

This is the second part of a series devoted to providing complete working examples of advanced use cases for insets on Android. The snippets in these posts can be found in context at https://github.com/alexvanyo/android-edge2edge. Part 1: Responding to keyboard transitions with MotionLayout Part 2: Insets and BottomSheetDialogFragment Part 3: Mind…

Dagger Hilt, JaCoCo, Robolectric, Espresso, oh my! Dagger Hilt is Google’s new opinionated add-on for setting up Dagger 2 for Android. Through its tie-ins with androidx and preconfigured components, it should be able to meet the common dependency injection demands of most apps. Google also lays out a testing philosophy…

Enums are dead, long live enums! This is the origin story for https://github.com/livefront/sealed-enum, a Kotlin annotation processor for generating enum-like objects from sealed classes of objects. …

Take this seemingly simple piece of Kotlin code, which we will run on the JVM platform: Seems like it might be a good guessing strategy for a multiple choice test (assuming a computer didn’t generate it, of course). Since all good code comes with tests, let’s make sure our…

In a perfect world, the consumer and producer of an API would always be in lockstep, only changing with each other and adhering to the strictest of contracts. …
