Make a Timer App: Countdown Timer (Ep 2) – Android Kotlin Tutorial

Learn how to create a beautiful material design timer app for Android.

In this course you will learn how to make a user interface. Later we’re going to code a timer which can run in the foreground. Then we are going to upgrade it to be able to run also in the background – and we will control it from notifications! Finally we will create a settings activity where a user will be able to set the length of the timer.

In the second part we’re coding the actual timer (CountdownTimer) which can run in the foreground. We’re also using shared preferences to persistently store certain data like timer length or seconds remaining.
