We have taken a concise look at some of the features Kotlin has put at our disposal for developing powerful applications. Over the course of this book, we will explore how these features can be utilized in Android application development - an area in which Kotlin shines.

Before getting started on this journey, we must set up our systems for the task at hand. A major necessity for developing Android applications is a suitable IDE - it is not a requirement but it makes the development process easier. Many IDE choices exist for Android developers. The most popular are:

• Android Studio
• Eclipse
• IntelliJ IDE

Android Studio is by far the most powerful of the IDEs available with respect to Android development. As a consequence, we will be utilizing this IDE in all Android-related chapters in this book.
