In this series we’re going to build an app to view the Mandelbrot set. While this is not necessarily something that is likely to be of direct use to the majority of app developers (except for those that have a desire to develop their own Mandelbrot set viewing apps), there are some techniques that we’ll…

Mandelbrot: Basic Viewer
In this series we’re going to build an app to view the Mandelbrot set. While this is not necessarily something that is likely to be of direct use to the majority of app developers (except for those that have a desire to develop their own Mandelbrot set viewing apps), there are some techniques that we’ll…
Mandelbrot: Rendering
In this series we’re going to build an app to view the Mandelbrot set. While this is not necessarily something that is likely to be of direct use to the majority of app developers (except for those that have a desire to develop their own Mandelbrot set viewing apps), there are some techniques that we’ll…
Mandelbrot: Basic Theory
In this series we’re going to build an app to view the Mandelbrot set. While this is not necessarily something that is likely to be of direct use to the majority of app developers (except for those that have a desire to develop their own Mandelbrot set viewing apps), there are some techniques that we’ll…
MotionLayout: Dynamic Toolbar
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.
Biometrics – AndroidX
Android has supported fingerprint sensors since API 23 and previously we looked at the new APIs to handle them using BiometricPrompt and BiometricManager. 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…
