Implementing ExoPlayer
Integrating ExoPlayer into your Android project is straightforward and well-documented. Here’s a step-by-step guide to getting started:
- Adding Dependency: Begin by adding the ExoPlayer dependency to your project’s build.gradle file. This can be done by including the necessary dependencies from the official ExoPlayer repository.
implementation("androidx.media3:media3-exoplayer:1.3.1")
implementation("androidx.media3:media3-exoplayer-dash:1.3.1")
implementation("androidx.media3:media3-ui:1.3.1")compileOptions {
targetCompatibility JavaVersion.VERSION_1_8
}- Create PlayerView: The desired video will be played on this added PlayerView.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"

<androidx.media3.ui.PlayerView
android:id="@+id/playerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"/>
</LinearLayout>- Creating ExoPlayer Instance: Instantiate an ExoPlayer object in your activity or fragment. Use the builder pattern to configure player settings such as audio and video renderers.
val player = ExoPlayer.Builder(context).build()- Attaching Player to View: Attach the ExoPlayer instance to a PlayerView, which serves as the primary interface for controlling playback and rendering video content. PlayerView encapsulates essential components like playback controls and surface for video rendering.
val videoUri = Uri.parse(
"android:resource://"
+ packageName
+ "/"
+ R.raw.video_file
)val player = ExoPlayer.Builder(this).build()
binding.playerView.player = player- Loading Media Items: Prepare the player by loading media items such as video URIs or media files. ExoPlayer supports various media sources, including local files, remote URLs, and streaming protocols.
val mediaItem = MediaItem.fromUri(videoUri)
// val secondMediaItem = MediaItem.fromUri(secondVideoUri)
player.setMediaItem(mediaItem)
// player.setMediaItem(secondMediaItem)- Playing the Video: Initiate playback by calling the play() method on the ExoPlayer instance. Users can interact with the built-in controls provided by PlayerView, allowing them to play, pause, seek, and adjust volume seamlessly.
