Question

I am a complete beginner at android studio.

and I am working on a simple application in which I have to stream a video from a URL. Just a simple Exoplayer I tried the below code but it doesn't work. If anybody knows please help.

XML

<com.google.android.exoplayer2.ui.PlayerView
    android:id="@+id/exoplayer"
    android:layout_width="match_parent"
    android:layout_height="500dp"
    android:foregroundGravity="center"

JAVA

    PlayerView playerView;
    SimpleExoPlayer simpleExoPlayer;

    simpleExoPlayer = new SimpleExoPlayer.Builder(this).build();
    playerView = findViewById(R.id.exoPlayerView);
    playerView.setPlayer(simpleExoPlayer);
    MediaItem mediaItem = MediaItem.fromUri(my video url);
    simpleExoPlayer.addMediaItem(mediaItem);
    simpleExoPlayer.prepare();
    simpleExoPlayer.play();

First make sure that you have the internet permission added to the manifest <uses-permission android:name="android.permission.INTERNET" />. After that you can try to add android:usesCleartextTraffic="true" to the manifest in the application tag.

Here is an example of the manifest file:

<manifest ...>
  ...
  <uses-permission android:name="android.permission.INTERNET"/>
  ...
  <application
    android:usesCleartextTraffic="true"
    ...>

    ...

  </application>
</manifest>

In your *.java class add this

simpleExoPlayer = new SimpleExoPlayer.Builder(this).build();
playerView = findViewById(R.id.exoPlayerView);
playerView.setPlayer(simpleExoPlayer);
MediaItem mediaItem = MediaItem.fromUri("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4");
simpleExoPlayer.addMediaItem(mediaItem);
simpleExoPlayer.prepare();
simpleExoPlayer.setPlayWhenReady(true);

The setPlayWhenReady(true) is required when you are playing a video from URL.
