Lessons in Kotlin Threading: An Animated Splash Screen

March 29, 2018  2 minute read  

I find quite a lot of Android apps have splash screens. Some splash screens are for showing off the logo; others for hiding the extensive data load times. Whatever the reason, it’s a way for a little bit of creativity to shine through. My first effort My new app needs a splash screen. Splash screens aren’t hard until you need to do something that takes some time, and there are many tutorials on how to produce one out on the Internet. I’m going to focus on the one problem I had. Let’s take a...

The React Toolbox - 2018 Edition

March 23, 2018  5 minute read  

It’s been a while since I’ve been in web development. I’ve mostly been concentrating on mobile development instead. But this week I had cause to delve again. It’s amazing how much change there has been in the web world in just 2 years. React has become the force in web frameworks (Sorry Angular — I never liked you anyway) and developers are starting to coalesce around libraries and tools that make their life easier. I thought I’d put down my thoughts on the libraries that are making it into m...

After all, I tried Swift for iOS as an alternate language and it felt foreign. Admittedly, Objective-C isn’t much better, but Swift definitely had some issues for ...

Testing Mobile Apps: A Primer

March 11, 2018  10 minute read  

Why should you test your mobile app? A recent study showed that almost a quarter of users only use a mobile app once, and a shocking 95% abandon an app within the first month. Some of the reasons that users abandon an app are due to content and engagement. The biggest non-content reasons for abandonment are application crashes and security concerns. No one can prevent all application crashes. The mobile ecosystem is too broad and unpredictable to provide a 100% guarantee. However, testing ens...

The Six Mobile Apps You Should Write

March 10, 2018  2 minute read  

Take a look at the mobile apps on the app stores and you will see patterns emerge. The same pattern is repeated time and time again. It’s crazy to think about this, but you only need to learn how to write six mobile apps that implement the common patterns. You can then pretty much write any app that is out there. Your First App: Notes or Task List There is a reason that just about every beginner tutorial uses the Todo app or the Notes app as the base. It’s a solid basic app that has a varie...
