Použitelnost jazyka Kotlin při vývoji mobilních aplikací

The main goal of this thesis is to demonstrate the advantages of the Kotlin programming language compared to its predecessor Java on the Android mobile plat-form. The theoretical part first presents the history and trends of development tool for mobile development, then describes the advantages of using the Kotlin programming language compared to Java. Description of Kotlin benefits is divided into four categories (object-oriented, functional, generic and parallel programming). The practical part contains a presentation of a mobile application for the Android plat-form created to demonstrate some of the advantages mentioned in the theoretical part. The application is developed in Kotlin. Android Studio has been used as the development environment. The practical part of the thesis is divided into four functional areas (navigation, REST API calling and subsequent data processing, application database creation and database data management, reminders). Each area is divided into two parts, the definition of the requirement is described first, followed by the implementation of the solution. The following is a user guide for the sample mobile application described in the practical part of the thesis. The user guide will help users navigate in the application. After reading this thesis, the reader should be able to understand what the development of mobile applications for Android platform in the Kotlin programming language brings compared to the previous development in Java. The reader should also be able to use the described constructs in practice.
