Android ExoPlayer :

Android ExoPlayer is used to play videos in the android app, in this tutorial we will see the integration.It’s an alternative to  default media player provided by android.

Using ExoPlayer we can directly stream videos over HTTP, also can providing customization’s.

Because Exoplayer is a open source we can customize the code according to the requirement like we can add cache support to reduce data usage.

We can add playlists to the player and this supports multiple file formats also subtitles.Different other features like ad-insertion, live streaming are supported.

ExoPlayer is a best option to play videos in splash screen, dashboard and can also play in any screen in your app.

Exoplayer allows you to use part of the library rather than using the entire library to minimize apk size, just consider the library’s required for your purpose.

 

Android exoplayer video tutorial :

Go through the below video tutorial for detailed video player integration.

 

Project Structure :

This below image will depicts the project structure of  exoplayer

 

Dependencies :

Add a exoplayer dependency to your build.gradle(:app)

implementation 'com.google.android.exoplayer:exoplayer:2.10.4'

 

activity_main.xml :

Add a exoplayer to layout file inside which there is a progress bar using which we will wait until the video is ready to be played.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
    tools:context=".MainActivity">

    <com.google.android.exoplayer2.ui.PlayerView
        android:id="@+id/playerView"
        android:focusable="true"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ProgressBar
            android:id="@+id/progressBar"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:visibility="gone"/>

    </com.google.android.exoplayer2.ui.PlayerView>
</androidx.constraintlayout.widget.ConstraintLayout>

 

MainActivity.kt :

Add required variables simpleExoPlayer and mediaDataSourceFactory

private lateinit var simpleExoPlayer: SimpleExoPlayer
private lateinit var mediaDataSourceFactory: DataSource.Factory

 

Now initialize simpleExoPlayer

simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(this)

 

mediaDataSourceFactory = DefaultDataSourceFactory(this, Util.getUserAgent(this, "mediaPlayerSample"))

 

Declare the source of the video here we are providing video url

val mediaSource = ProgressiveMediaSource.Factory(mediaDataSourceFactory).createMediaSource(Uri.parse(STREAM_URL))

 

simpleExoPlayer.prepare(mediaSource, false, false)
simpleExoPlayer.playWhenReady = true

playerView.setShutterBackgroundColor(Color.TRANSPARENT)
playerView.player = simpleExoPlayer
playerView.requestFocus()

 

override methods for start, resume, stop and pause.

private fun releasePlayer() {
    simpleExoPlayer.release()
}

public override fun onStart() {
    super.onStart()

    if (Util.SDK_INT > 23) initializePlayer()
}

public override fun onResume() {
    super.onResume()

    if (Util.SDK_INT <= 23) initializePlayer()
}

public override fun onPause() {
    super.onPause()

    if (Util.SDK_INT <= 23) releasePlayer()
}

public override fun onStop() {
    super.onStop()

    if (Util.SDK_INT > 23) releasePlayer()
}

 

Provide the url of the video

companion object {
    const val STREAM_URL = "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4"
}
