Exercise – using coroutines in an Android app

In this exercise, you will be working with an application that displays movies that are playing now in cinemas. You will be using The Movie Database API version 3 to get the list of movies. Go to https://developers.themoviedb.org/3 and register for an API key. Once you’ve done that, follow these steps:

1. Open the Movie App project in the Chapter02 directory in this book’s code repository.
2. Open MovieRepository and update apiKey with the value from The Movie Database API:

   private val apiKey = "your_api_key_here" 

3. Open the app/build.gradle file and add a dependency for kotlinx-coroutines-android:

   implementation ‘org.jetbrains.kotlinx:kotlinx-
     coroutines-android:1.6.0’

This will add the kotlinx-coroutines-core and kotlinx-coroutines-android libraries to your project, allowing you to use coroutines in your code.

4. Also, add the dependencies for the ViewModel extension...
