Android does not display m3u8 format in videoview,

Question

I didn't use a real device, I was working on emulator. (Problem Solved)

I am developing a live stream video application. I have so many live stream URLs which have *.m3u8 postfix.

When I start the app, I can hear only sound but no video displaying. Video display area is always dark.

I am waiting for your helpful suggestions to solve my problem.

Regards.

Some of my code:

public class MainActivity extends Activity {

    private static ProgressDialog progressDialog;

    String videourl = "URL/playlist.m3u8";
    VideoView videoView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        videoView = (VideoView) findViewById(R.id.video_View);

        progressDialog = ProgressDialog.show(MainActivity.this, "", "Buffering video...", true);
        progressDialog.setCancelable(false);

        PlayVideo();
    }

    private void PlayVideo() {
        try {
            getWindow().setFormat(PixelFormat.TRANSLUCENT);

            MediaController mediaController = new MediaController(MainActivity.this);
            mediaController.setAnchorView(videoView);

            Uri video = Uri.parse(videourl);
            videoView.setMediaController(mediaController);
            videoView.setVideoURI(video);
            videoView.requestFocus();
            videoView.setVisibility(View.VISIBLE);

            videoView.setOnPreparedListener(new OnPreparedListener() {

                public void onPrepared(MediaPlayer mp) {
                    progressDialog.dismiss();
                    videoView.start();

                }
            });

        } catch (Exception e) {
            progressDialog.dismiss();
            System.out.println("Video Play Error :" + e.toString());
            finish();
        }

    }

}
