This module consists of lessons devoted to the fundamental building blocks of the language. You will learn the Kotlin variable and type system, basic operators and ranges, and control structures in lesson 1. At lesson 2, you will be introduced to the definition of a function, its modifiers and where it can be defined along with various enhancements in Kotlin, including lambdas, function type, named and default parameters. Lastly, you will create small programs to learn about Classes and Objects.

Begin with an overview of Android system and its version history, you will learn to setup the official IDE by following the detailed installation instructions, create your first Android app, build and run it on a device and emulator. Along the process, you will be introduced to the basic Android Studio features and its Tool windows, explore how an Android project and its app module are structured.

Plays a great part in mobile apps, it gives the look and feel, the presentation, and the overall interactivity of an app. In the first part of this module, you will learn the structure and components of an Android UI and how it is built in detailed.
