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.

Before they start coding something, most programmers begin by creating a data flow diagram to know exactly how each piece of code is supposed to work (how it should behave). If the behavior of the application is not complicated, you do not have to sketch it (although it is a good habit, even with simple things), but with more complicated behavior, it is hard to properly code such flow.

iOS 10 offers many new features. One of them is CallKit, the framework which allows our application to seamlessly integrate with the user interface of a phone. CallKit may be used in applications to allow users to receive incoming calls and perform outgoing calls with the phone-provided UI. VoIP call can be muted or suspended. It is also possible to make video calls.

In iOS 10 we can use SFSpeechRecognizer API, which allows transcription in real-time or using pre-recorded audio files. The outcome of such transcription is not only a text, but also alternative interpretations of the audio, length of spoken words and level of accuracy of recognized words (range 0.0 - 1.0). API allows for the analysis of more than 50 languages. Using SFSpeechRecognizer API in an application is trivial, it boils down to four steps.

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.
