Exoplayer how to know which URL to be played with custom video view

Question

I am working on an online Video player, I am using TextureVideoViewMute extends TextureView implements TextureView. SurfaceTextureListener custom class as custom video player.

I am having two URLs in my response source_url(main URL) and dash_url.Now I wanted to use ExomediaPlayer for this but I have the following questions.

1. How to categorize which URL to be played?

2. Or Whether this will be decided by the player itself while playing?

3. Or we need to use a single URL player automatically do his work?

4.Or is it possible combination of custom video surface view and SimpleExoPlayer?

How to achieve adaptive bitrate streaming like you-tube 144p 220p 720p... etc according to network condition?

I have tried the examples provide on GIT but they are either playing dash_url or source_url

Exoplayer Sample

Sample code of Exoplayer

  String videoURL = "http://blueappsoftware.in/layout_design_android_blog.mp4";

    SimpleExoPlayerView exoPlayerView = (SimpleExoPlayerView) findViewById(R.id.exo_player_view);
    try {


        BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
        TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
        SimpleExoPlayer exoPlayer = ExoPlayerFactory.newSimpleInstance(this, trackSelector);

        Uri videoURI = Uri.parse(videoURL);

        DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("exoplayer_video");
        ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
        MediaSource mediaSource = new ExtractorMediaSource(videoURI, dataSourceFactory, extractorsFactory, null, null);

        exoPlayerView.setPlayer(exoPlayer);
        exoPlayer.prepare(mediaSource);
        exoPlayer.setPlayWhenReady(true);
    } catch (Exception e) {
        Log.e("MainAcvtivity", " exoplayer error " + e.toString());
    }

You can get the current player source (uri) by calling:

player.currentMediaItem?.playbackProperties?.uri
