Kotlin

Kotlin and Java are two powerful general-purpose languages popular for Android and beyond. We’ll discuss their top features and differences, then focus on how to smoothly transition between the two.

The functional reactive programming (FRP) paradigm is becoming increasingly mainstream. In this installment, we discuss FRP essentials like system design and libraries, and implement a sample application.

This tutorial explores the mathematical concepts behind two key programming paradigms, functional programming and reactive programming, so you can build long-lasting Android architecture.

Kotlin has features that make it an ideal language for back-end development. Learn what these features are and how you can use them to create high-performing systems.

It’s easy to get entangled in spaghetti code, fuzzy responsibilities, and opaque architecture. It is just as easy to write crisp, clear code that is just as easy to write, maintain, and update with a little forethought. Join Toptal Android Developer Tomasz Czura as he guides you through the process and the reasoning behind creating clean architecture on Android.

Keeping your Android codebase maintainable as your codebase grows can be a challenge. In this article, Toptal Freelance Android Developer Abhishek Tyagi shows how to combine MVVM with Clean Architecture—the latter as described by Robert C. Martin—to write decoupled, testable, and maintainable code.

Kotlin is a new, expressive, general-purpose programming language powered by the same virtual machine technology that powers Java. Since Kotlin compiles to the JVM bytecode, it can be used side by side with Java, and it does not come with a performance overhead. In this article, Toptal Freelance Software Engineer Ivan Kušt gives us a walkthrough of 10 major features of Kotlin that help avoid boilerplate code and, more importantly, save time.
