Android Video Player Development Tutorial82

In this tutorial, we'll learn how to create a video player with Android's new library, Exoplayer. We'll cover how to set up Exoplayer, play and control videos, and handle playback events.

Setting Up Exoplayer

First, add the Exoplayer dependency to your project's file:```
dependencies {
implementation ':exoplayer:2.18.1'
}
```

Next, create a layout file for your video player. Here's a simple example:```





```

In your activity or fragment, initialize Exoplayer:```kotlin
// Get the player view
val playerView = findViewById(.player_view)
// Create an instance of the ExoPlayer
val player = (this).build()
// Set the player view for Exoplayer
= player
```

Playing and Controlling Videos

To play a video, load a media source into the player:```kotlin
val mediaSource = (this).createMediaSource(uri)
(mediaSource)
()
```

To control the playback, use the player's methods:```kotlin
// Pause the playback
()
// Resume the playback
()
// Seek to a specific position
(1000)
```

Handling Playback Events

To handle playback events, implement the interface:```kotlin
(object : {
override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
// Handle playback state changes
}
override fun onPlayerError(error: ExoPlaybackException) {
// Handle playback errors
}
})
```

When you're done with the player, release it to free up resources:```kotlin
()
```

Conclusion

This tutorial has introduced the basics of creating a video player with Exoplayer. With Exoplayer, you can easily play and control videos in your Android app.
