ConstraintLayout is a popular solution that Android developers use every day. And not without a good reason. If you’re at the beginning of your journey as a software engineer, get familiar with the most important features this layout can offer. It will help you understand the way it works, and Android app development will become easier.

Every person with software development experience can share a few stories about incorrectly working features. We build our apps out of small pieces, introduce advanced architecture patterns, and yet sometimes one of the elements fails, causing bugs or even system failures. In such cases, feature toggling can save the day! Find out how to implement feature flags, and make your app more stable.

With the release of Android Studio version 2.2, Google has given developers a lot of new features. One of them is Espresso Test Recorder. What is it and how it makes running tests easier?

When creating an application, sometimes at some point we want to get several versions of our application that differ in some more or less important details. To easily obtain different versions of your application, just make a few changes in Gradle.

Clean Architecture can be approached in several ways. One solution is to use RxJava 2, and in this post we will take a close look at this approach.In the presentation layer we will use the proven standard Model View Presenter, in the domain layer we will have UseCases with a single responsibility, and in the data layer we will apply Repository Pattern. All of this will be controlled with RxJava streams.

BDD or Behavior-Driven-Development is a method of programming in which business clients, developers and testers describe the behavior of the application with the help of scenarios. The scenarios are written using agreed notation and language, so that they are understood by all parties.

In recent editions of Android system, settings underwent a small revolution. The main settings screen has been reorganized, new options have been added. Android Lollipop introduced shortcuts to quickly switch most important settings so that they are visible immediately after expanding the upper panel. Android Nougat, along with the API 24, provided us with the ability to add our own settings there, related to our application.

With the new Android version, Nougat 7.1 (API 25), Google gives us some interesting possibilities. One of them is the option to create shortcuts to an application. In this post I will show you how static shortcuts work.

When getting into the subject of dependency injection, we need to understand numerous new techniques that enable us to control created objects. Dagger allows developers to declare interfaces that will handle that. We can create an interface which will be a component or a subcomponent. What is the difference?
