How to setup Exoplayer in Android Studio?

 Exoplayer setup in Android Studio

Past playerView Code to your Layout file :

<com.google.android.exoplayer2.ui.PlayerView
    android:id="@+id/videoView"
    android:layout_width="match_parent"
    android:layout_height="225dp"
    android:background="@android:color/black">

</com.google.android.exoplayer2.ui.PlayerView>

Your Activity Code to setup Player :

LoadControl loadControl = new DefaultLoadControl();
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelector trackSelector = new DefaultTrackSelector(
        new AdaptiveTrackSelection.Factory(bandwidthMeter)
);
simpleExoPlayer = ExoPlayerFactory.newSimpleInstance(
        this, trackSelector, loadControl
);
DefaultHttpDataSourceFactory factory = new DefaultHttpDataSourceFactory(
        "Video"
);
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
MediaSource mediaSource = new ExtractorMediaSource(Uri.parse(video),
        factory, extractorsFactory, null, null
);
videoViewPath.setPlayer(simpleExoPlayer);
videoViewPath.setKeepScreenOn(true);
simpleExoPlayer.prepare(mediaSource);
simpleExoPlayer.setPlayWhenReady(false);
simpleExoPlayer.addListener(new Player.DefaultEventListener() {
    @Override
    public void onTimelineChanged(Timeline timeline, Object manifest, int reason) {
        super.onTimelineChanged(timeline, manifest, reason);
    }

    @Override
    public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
        super.onTracksChanged(trackGroups, trackSelections);
    }

    @Override
    public void onLoadingChanged(boolean isLoading) {
        super.onLoadingChanged(isLoading);
    }

    @Override
    public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
        super.onPlayerStateChanged(playWhenReady, playbackState);
        switch (playbackState) {

            case Player.STATE_BUFFERING:
                progressBar.setVisibility(View.VISIBLE);
                break;
            case Player.STATE_ENDED:

                break;
            case Player.STATE_IDLE:
                break;
            case Player.STATE_READY:
                progressBar.setVisibility(View.INVISIBLE);
                break;
            default:
                break;

        }
    }

    @Override
    public void onRepeatModeChanged(int repeatMode) {
        super.onRepeatModeChanged(repeatMode);

    }

    @Override
    public void onShuffleModeEnabledChanged(boolean shuffleModeEnabled) {
        super.onShuffleModeEnabledChanged(shuffleModeEnabled);
    }

    @Override
    public void onPlayerError(ExoPlaybackException error) {
        super.onPlayerError(error);
    }

    @Override
    public void onPositionDiscontinuity(int reason) {
        super.onPositionDiscontinuity(reason);
    }

    @Override
    public void onPlaybackParametersChanged(PlaybackParameters playbackParameters) {
        super.onPlaybackParametersChanged(playbackParameters);
    }

    @Override
    public void onSeekProcessed() {
        super.onSeekProcessed();
    }
});

We will Create A Demo App For Better Understanding :
