Problem

Not able to find information about androidx.media2.VideoView. I want to stream a video from an url which is working with VideoView1, however I can't achieve it withVideoView2.

My Research

In the documentation they describe this method:

setVideoUri open fun setVideoUri(uri: Uri!, headers: MutableMap<String!, String!>?): Unit Sets video URI using specific headers.

However this method seems to be no longer available (I am using mediaWidgetVersion 1.0.0-alpha06)

For future references androidx.media2.widget.VideoView's simple usage is:

  1. Create MediaMetadata if required. Here I'm simply setting media title
  val mediaMetaData = MediaMetadata.Builder()
      .putString(MediaMetadata.METADATA_KEY_TITLE, "media title")
      .build()
  1. Create MediaItem from any sources. Here I'm using url as a source
  val mediaItem = UriMediaItem.Builder(videoUrl.toUri())
      .setMetadata(mediaMetaData) // optional
      .build()
  1. Create SessionPlayer and set it to VideoView by calling setPlayer
  val mediaPlayer = MediaPlayer(this)
  with(mediaPlayer) {
    videoView.setPlayer(this)

    setMediaItem(mediaItem)
    // play when ready
    prepare().addListener(
      Runnable { play() },
      Executors.BACKGROUND_EXECUTOR
    )
  }

You should use MediaItem internal builder like this to create a UriMediaItem

UriMediaItem yourUriMediaItemHere = new UriMediaItem.Builder(context, uri).build();

and then use videoViews setMediaItem method like this

videoView.setMediaItem(yourUriMediaItemHere);

According to this document: https://developer.android.com/reference/androidx/media2/widget/VideoView

Using VideoView with SessionPlayer or MediaController For simple use cases that do not require communication with a MediaSession, apps need to create a player instance that extends SessionPlayer (e.g. MediaPlayer) and link it to this view by calling setPlayer(SessionPlayer). For more advanced use cases that require a MediaSession (e.g. handling media key events, integrating with other MediaSession apps as Assistant), apps need to create a MediaController that's attached to the MediaSession and link it to this view by calling setMediaController(MediaController).

But there's one very important thing which didn't get noted from this document.

Here's the code snippet about how to use this new VideoView.

MediaMetadata mediaMetaData = new MediaMetadata.Builder()
        .putString(MediaMetadata.METADATA_KEY_TITLE, url)
        .build();

UriMediaItem mediaItem = new UriMediaItem.Builder(Uri.parse(url)).build();
mediaItem.setMetadata(mediaMetaData);

MediaPlayer mediaPlayer = new MediaPlayer(getActivity());
mediaPlayer.setMediaItem(mediaItem);
mediaPlayer.prepare();

videoView.setPlayer(mediaPlayer);

You have to call mediaPlayer.prepare() to tell the MediaPlayer to start loading. Otherwise you'll get IllegalStateException with useless messages.
