Using Coroutines on Android

Coroutines were added in Kotlin 1.3 to manage background tasks such as making network calls and accessing files or databases. Kotlin coroutines are Google’s official recommendation for asynchronous programming on Android. Their Jetpack libraries, such as LifeCycle, WorkManager, and Room, now include support for coroutines.

With coroutines, you can write your code in a sequential way. The long-running task can be made into a suspending function, which, when called, can pause the thread without blocking it. When the suspending function is done, the current thread will resume execution. This will make your code easier to read and debug.

To mark a function as a suspending function, you can add the suspend keyword to it; for example, if you have a function that calls the getMovies function, which fetches movies from your endpoint and then displays it:

val movies = getMovies()
displayMovies(movies)

You can make the getMovies() function a suspending...
