Strange Fragment/View lifecycle interaction, Rx leaks, and dependency leaks — This article is a continuation of part 1 of this mini series of memory leaks cookbook for Android. Talking about memory leaks sometimes involves more than the technical problem itself. For one concern, the definition of a memory leak is subjective. The authors of Programming Android with Kotlin: Achieving Structured…

A quick reference guide loosely based on “Programming Kotlin with Android: Programming Kotlin with Android” — Out in the wild, Android faces real-life challenges that affect performance and battery life. For example, not everyone has unlimited data in their mobile plans, or reliable connectivity. Android apps must compete with one another for limited resources. Performance considerations allow you to examine concerns that may impact your application’s…

Lexers, parsers, PSI, AST v. CST, and other fundamental concepts to help understand writing IDE/compiler plugins — As programmers, we like to talk about tech things being a “black box”. For better or worse, the Kotlin compiler feels a bit like one. There is documentation around Kotlin PSI use for IDE plugins, but aside from whatever comments are left in the source code, there’s not too much…

A closer look at the relationship between Kotlin and programmatic/dynamic view inflation — Today, we explore the question “Where does initialization occur around the lifecycle of a view?” This is topic my teammates hotly debated over for months, so I’ve decided to see for myself. This blurb covers two ways of inflating a custom view for comparison: via layout resource and programmatically.

Part 1: Navigation UI, MVVM, and the SingleFragmentActivity Pattern — Space Coast, Florida has one of the world’s most unique environments in the world. The St. John’s River is one of 3 rivers in the world to flow north, and for Brevard County, the Indian River and the Banana River are estuaries, which are warm part-salt/part-fresh water bodies, giving home…

Kotlin data classes and working with them in Mockito testing ლ(ಠ_ಠლ) — Today, I’m going to talk about the benefits of using Kotlin data classes — in particular, working with them in unit testing. I’ve discovered some neat things about Kotlin data classes while rewriting Android features, and thought I’d share insights I’ve gained through a fun example! Note: this blurb only…
