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 ten major features of Kotlin that help avoid boilerplate code and, more importantly, save time.
