You need to use HLS media source to play m3u8 file.

use this

private MediaSource buildMediaSource(Uri uri) {
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, "exoplayer-codelab");
    return new HlsMediaSource.Factory(dataSourceFactory).createMediaSource(uri);
}

instead of this

private MediaSource buildMediaSource(Uri uri) {
    DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(this, "exoplayer-codelab");
    return new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(uri);
}
