Regular readers of Styling Android may have guessed that I rather enjoy animating things. MotionLayout offers amazing scope for animations and it’s possible to create some really interesting animations using it. We’ve looked at how to implement a Collapsing Toolbar previously on Styling Android, but we’re not limited to just mimicking existing behaviours which can…
Parallax Scrolling
Parallax scrolling can be a really interesting technique to use to give parts of your app a bit more life and character. It is a technique built on the mathematical principle if we are moving then objects closer to us appear to move faster than those further away. A great example of this is if…
ViewPager2
ViewPager has been around for a number of years now, and was added in support library V22.1.0. In February 2019 the first alpha of ViewPager2 was released. In this post we’ll take a look at how ViewPager2 differs from ViewPager, and how to implement it.
Parcelize
A Parcel is an optimised serialisation format for Android which is designed to enable us to transfer data between processes. This is something that most Android developers need to do occasionally, but not that often. Making a class Pareclizable actually requires a little bit of effort, but there’s a Kotlin extension that simplifies things enormously.…
HEIF Images
One of the new features in Android Q is support for High Efficiency Image Format (HEIF) images, but why is this important? In this post we’ll take a look at what HEIF actually is, and understand a little about the benefits that it might offer.

For the latter we looked at how to create a compat wrapper so that this works back to API 23. But we didn’t implement one for BiometricPrompt. Since writing those articles, I…
Burnout
Recently I saw a tweet by Britt Barak stating that we don’t talk about burnout enough and she’s also recorded a podcast about it. This made me think about my experiences with burnout and it made me wonder if sharing my experiences might help others who are unfortunate enough to be experiencing it as well.
Gesture Navigation – Window Insets
One of the big Android announcements at Google I/O 2019 was the introduction of gesture navigation on Android Q. Initially it may feel like this is purely a system-level change and does not affect apps directly, but closer inspection reveals that apps may need to change to properly accommodate this. The touch areas that the…
