Last updated 139 days ago by Rachit Mishra


In this tutorial, you will learn how to use lambda expressions and other functional literals provided by Kotlin for the Android platform.

Lambda expression is a simplified representation of a function. It can be passed as a parameter, stored in a variable or even returned as a value.

To practice using lambda expressions, you will build a simple app to save and manage your favorite songs. It will have the functionality to:

  • Display favorite songs on a list with playlist range.

While doing so, you will explore the following Kotlin topics:

  • Lambdas
  • Anonymous functions
  • Higher-order functions
  • Closures

Time to start learning!
