00:02Just to show how easy implementing coroutines is, and how the code is more understandable than using callbacks, or some other mechanism, you’ll change the deleteTask API call, to rely on Coroutines. Let’s see how to do just that! :]

00:15To start implementing coroutines, you need to add their dependency to the project. Open app level build.gradle. Then add the following dependencies to the project:

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.6.4'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.6.4'
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.5.1'
