Building a mobile app isn't cheap—and the harsh reality is that most apps fail. Find out how to leverage fundamental analytics metrics to make sure your app actually turns a profit.

Cross-platform mobile apps are increasingly being built with React Native. But how can you scan for QR codes and augment the user's camera view when they're present?

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.

Despite initial skepticism, React Native is very much in demand today! In this article, Toptal Freelance React Native Developer, and former React Native skeptic, Alexander Pataridze talks about why he became a React Native advocate instead and introduces us to the technology by illustrating four use-cases.

There is no way around application diagnostics. No matter how good your code is, you will need to be able to monitor and study system behavior. This is where Android's DDMS shines. In this article, Senior Android Engineer Gilad Haimov explains how veteran Android developers leverage the potential of DDMS to improve app stability and performance, test new features, diagnose, and debug their code.

Android provides many ways of creating and managing threads, and third-party libraries exist to make that even easier. However, with so many options, choosing the right approach can be quite confusing. In this article, Toptal Freelance Software Engineer Eliran Goshen discusses some common scenarios in Android development that involve threading and how each of the scenarios can be dealt with.

Dealing with concurrency in Android through imperative-style programming can be quite the hassle. RxJava, a library for reactive and functional style programming, allows concurrency constructs to be modeled in a reactive way in Android's non-reactive world. In this article, Toptal Freelance Software Engineer Christopher Arriola shows us how RxJava can be incrementally introduced to existing Android projects and leveraged to simplify concurrency.

Since the inception of the platform, Android developers have had pretty much only one option for a database: SQLite. Although feature-rich and powerful, it wasn’t quite what Android app developers needed. Realm, a modern, efficient database solution for mobile platforms, turned out to be an amazing replacement for SQLite on Android. In this article, Toptal Software Engineer Mateus Gondim Romão Batista explains why you should use Realm for your next Android application.
