Does anyone have any information on how to get a broadcast link from the Twilio API?

I want to stream video with VideoTextureView. I tried to do it with the code below, but I couldn't find a broadcast link with the Twilio API.

I'm receiving the following error:

> Caused by: java.lang.ClassCastException:
> com.twilio.video.VideoTextureView cannot be cast to
> android.widget.VideoView

My code:

public class MainActivity extends AppCompatActivity {
private ImageButton button, button1, button2;
private GridLayout gridLayout;
private ImageView circle, dislike, like;
private VideoView videoView;
private String videoPath;
private VideoTextureView videoTextureView;
private Uri uri;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.circle);
button1 = findViewById(R.id.dislike);
button2 = findViewById(R.id.like);
circle = findViewById(R.id.imageView);
dislike = findViewById(R.id.imageView2);
like = findViewById(R.id.imageView3);
circle.setVisibility(View.INVISIBLE);
dislike.setVisibility(View.INVISIBLE);
like.setVisibility(View.INVISIBLE);
videoView = findViewById(R.id.video_view_top_right);
Uri uri = Uri.parse(&quot;android.resource://&quot;+getPackageName()+&quot;/&quot;+R.raw.video);
videoView.setVideoURI(uri);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(MainActivity.this, &quot;Circle&quot;, 
Toast.LENGTH_LONG).show();
}
});
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(MainActivity.this, &quot;Dislike&quot;, 
Toast.LENGTH_LONG).show();
}
});
button2.setOnClickListener(new View.OnClickListener()
{

Toast.LENGTH_LONG).show();
findViewById(R.id.imageView);

Stream video in android VideoView and use screencast API of Twilio to broadcast your video. Twilio's VideoTextureView is for showing the camera view or screen.
