How to fix error "Can't play this video"? (m3u8) file

I'm working with ExoPlayer and m3u8 file. Every time when I run my app it says that

> Can't play this video

Probably everything should be right but I don't know why it says like that

XML file:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context=".MainActivity">


<VideoView
    android:id="@+id/video_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

MainActivity file:

public class MainActivity extends AppCompatActivity {

VideoView videoView;

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

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

    final ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
    progressDialog.setMessage("Please Wait");
    progressDialog.setCancelable(false);
    progressDialog.show();

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



    videoView.setVideoURI(Uri.parse("http://mos.rusiptv.net:8080/live/@celalsonat/784512/94815.m3u8"));
    videoView.start();

    videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            progressDialog.dismiss();
        }
    });
 }
} 

Thanks in advance!

there are many reasons for that..

1.If your video is corrupted then videoplayer shows that dialog..

2.if your video is completed and not corrupted then try this,

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        videoView.start();
        progressDialog.dismiss();
    }
});

3.Exoplayer is the best alternative of videoview in android studio.

just implement this dependancy, in several places

repositories {
   mavenCentral()
   jcenter()
}


dependencies {
...
compile 'com.google.android.exoplayer:exoplayer:2.8.0'

}

and Bam you done...

Hope this will help you..!!!

To play .m3u8 file use below code while initializing Exoplayer:-

BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();

TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);

TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);

videoPlayer = ExoPlayerFactory.newSimpleInstance(context,trackSelector);

Handler mHandler = new Handler();

String userAgent = Util.getUserAgent(context, "APPLICATION_NAME");

DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory(
                userAgent, null,
                DefaultHttpDataSource.DEFAULT_CONNECT_TIMEOUT_MILLIS,
                1800000,
                true);

HlsMediaSource mediaSource = new HlsMediaSource(Uri.parse(mediaUrl),dataSourceFactory, 1800000,mHandler, null);

if (mediaUrl != null) {
    videoPlayer.prepare(mediaSource);
    videoPlayer.setPlayWhenReady(true);
}
