android.view.InflateException：二进制XML文件第9行发生错误

我到处都在寻找，但是找不到该错误的任何解决方案。

我正在使用ExoPlayer进行实时视频流传输。而且我的应用每次运行时都会崩溃。如果您能帮助我，我会很高兴。

我猜它应该在XML文件中的某个位置，但是我不明白这是什么意思。XML：

<?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">

<com.devbrackets.android.exomedia.ui.widget.VideoView
    android:id="@+id/video_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:useDefaultControls="true"/>

</androidx.constraintlayout.widget.ConstraintLayout>

MainActivity文件：

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

    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("Here's path"));
    videoView.start();

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