Persistent Timer Android Studio Kotlin Tutorial | Background Stopwatch

How to build stop watch timer that keeps counting even if the app is closed in Android Studio & Kotlin.

We will use shared preferences to store the timer start time, timer stop time and a boolean whether the timer is counting. Being saved in shared preferences means that when the app is closed the values are remembered when the app is opened again.

Based of these three variables we can then deduct what the time should be on the timer.
