A “picker” is a small scrollable list of defined values that looks like a combination lock with dials. It’s native to Swift. I think “spinner” would be a better name, because it looks like it spins. (Android has a “spinner,” but it’s really just a drop-down list. Annoying.)
In this post, I will be showing you how to make a month picker/spinner in Kotlin. Read more on Building a Horizontal Picker or Spinner in Kotlin…
When creating any kind of application, it’s important to build it for the users you expect to be supporting. Because of this, it may be necessary to display different strings, images, and other content based on the language or region of your users.
While creating the translations of an app can be a lengthy process, enabling content localization in an Android app is as simple as adding new files and folders to your resources. Read more on An Introduction to Content Localization in Android Apps…
When using Xamarin.Forms, the conventional wisdom is that you write unit tests around the ViewModel, but not the View. This approach works well for most cases with MVVM, but if you’re developing custom controls, it’s likely not sufficient. In this post, I’m going to dive into a bit of what it takes to successfully write unit tests around custom Xamarin.Froms controls.
I have been working on a project for a cross-platform mobile application using Xamarin.Forms, and my team has found it surprisingly difficult to determine the best way to handle orientation changes in the application. Read more on Handling Orientation Changes in Xamarin.Forms – 5 Approaches…
I recently ran into an issue with providing style properties to custom React Native components written in TypeScript. When defining the type of the style property, we were using the ViewStyle and TextStyle types provided by React Native.

Working on a large(ish) React Native project presents some unique challenges for web and mobile developers. Isolating components from one another is a great way to make refactoring easy, but it leads to some pretty gnarly directory hierarchies.

With the dawn of the Internet of Things, smart homes, and connected devices, mobile apps have become key elements of creating harmony between everything. Most IoT devices require users to provision their devices on a home wireless network, which can sometimes cause poor user experience. However, apps have the ability to ease these pain points by programmatically connecting to wifi networks. Read more on Programmatically Connecting to WiFi in Your Xamarin.Forms App…
On my current project, we were searching for a good way to fake out our API for testing purposes. One idea that my teammate came up with was to create a local server within the actual Xamarin Forms app so we could make API calls to it.

My team was working on an activity tracking application and wanted to be able to display segments of time on a radial gauge. When implementing this feature, I initially tried using some libraries specifically designed to build arcs, but I was disappointed by their lack of flexibility. When my pair recommended looking into SkiaSharp, I was pleased to discover that not only could I build a radial gauge, but I also had quite a few options as to how to build it.

The device on our current project has two unique software development kits (one for Android and one for iOS). My team wanted to use Xamarin.Forms to create an application for the device so that the core logic of the app could be stored in one place.
However, in order to also incorporate the platform-specific SDK methods, we had to export Java code (for Android) and Swift code (for iOS) as libraries and then import those libraries into a Xamarin.Forms project. Read more on Exporting a Java Library to a Xamarin.Forms Android Project…
