There is a nice micro-animation library at useanimations.com which contains some useful animations which are particularly well suited for animated icons. These are all free to use and downloadable at Lottie animations. For those that already use Lottie they can use these animations as-is. However using them is apps which don’t use Lottie, or in…
Motion Vectors
Regular readers of Styling Android will not be surprised to hear that I rather like animations. A couple of really useful tools for creating nice animations are AnimatedVectorDrawable (AVD), and MotionLayout and it should come as no surprise that I am a big fan of both. But using them together is not easy. In this…

Kotlin: Serialization – Update
Last week I published an article covering the kotlinx.serialisation library and how it had the potential to overcome the issue of Kotlin object serialization using Java Serialization not correctly handling the object singleton implementation which under-pins Kotlin objects. However, at the time I wrote that article, Kotlin sealed class hierarchies were not supported by kotlinx.serialisation,…
Kotlin: Serialization
After chatting with Sebastiano Poggi about the issues with using Kotlin objects that I covered in a recent post, he made the interesting suggestion that possibly kotlinx.serialization might work better than the Java implementation because it is faster, more flexible (we can use different serialisation formats such as JSON or Protobuf), and is built with…
Qualifications
People are often surprised if I tell them that I do not have a university degree. I’m not someone who achieved a degree in a subject unrelated to computer science and then moved in to the field later in life. I chose not to go to university. In this non-technical post I’ll explain why I…

Kotlin: Serializable Objects
When is a Kotlin object not a Kotlin object? When it’s a Serializable Kotlin object. This blog post is the story of a strange issue that I encountered recently where a Kotlin object stopped behaving as it was supposed to, how I initially got it working with a bad fix, and how I eventually fixed…

BottomNavigationView: Animating Icons
There is an occasional series on Styling Android which covers techniques for creating Animated Icons as AnimatedVectorDrawable and AnimatedStateListDrawable. These are quite easy to use when using them inside a standard ImageView, but there can be other scenarios where they can be a little trickier to get working, and one of those is in the…
