This work aims to research and describe the development process, first through a theoretical part, and then through the actual creation of an Android application that will allow users to connect and easily communicate with moving and furniture transportation service providers. The technologies that will be covered and used in practice are: the Kotlin programming language, Android Studio development environment, Figma interface design tool, and the comprehensive Firebase application development platform. The external libraries used as part of the practical work are Jetpack Compose, Dagger Hilt, Glide, Gson, and Retrofit. These libraries have primarily enabled a different approach to interface creation without XML files, easy implementation of singletons for all components, and simple manipulation of data and images in communication with the database. The first part describes the purpose and goal of the work, followed by a theoretical section with an overview of approaches to Android application development throughout history, thus describing the theoretical part of individual technologies and approaches such as SOLID and clean architecture. The second part discusses the technologies used, their advantages and disadvantages, as well as the reason for their selection within the framework of this work. The last part concerns the concrete implementation through an Android application where we describe the development process from design to a functional application. The complete application code is available from a public repository on GitHub and can be found at the following link: https://github.com/XSSmachine/CityGo/tree/master
