Playing video using ExoPlayer

In this section, we’ll harness the full power of ExoPlayer so that we can integrate it into our newly created video playback UI. Let’s learn how we can do this.

Creating PlaybackActivity

We’ll start by creating a new Activity for this functionality called PlaybackActivity:

class PlaybackActivity: ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            PlaybackScreen()
        }
    }
}

This PlaybackActivity activity will show our already created PlaybackScreen() in its content.

We also want our playback UI to be always displayed in landscape mode. To do so, we’ll configure this activity in the AndroidManifest...
