Media Player in andorid studio

Issue

I am trying to create a media player without MediaPlayer class.Just a very basic videoview which selects a file from device and plays it.But I am receiving an error Can't play this video.

Here's my code:

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;
import android.widget.VideoView;

public class PlayerActivity extends AppCompatActivity {

    VideoView videoPlayer;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        videoPlayer = findViewById(R.id.videoView);
        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
        intent.setType("*/*");
        startActivityForResult(intent, 7);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case 7:
                if (resultCode == RESULT_OK) {
                    String PathHolder = data.getData().getPath();
                    Toast.makeText(this, PathHolder, Toast.LENGTH_SHORT).show();
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                    videoPlayer.setVideoURI(Uri.parse(PathHolder));
                    videoPlayer.requestFocus();
                    videoPlayer.start();
                }
        }
    }
}

XML file:

<androidx.constraintlayout.widget.ConstraintLayout xmlns:tools="http://schemas.android.com/tools"
    android:layout_height="match_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent">
        <VideoView
        android:id="@+id/videoView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layout_editor_absoluteX="318dp"
        tools:layout_editor_absoluteY="716dp" />
</androidx.constraintlayout.widget.ConstraintLayout>

This is what logcat shows(i guess this contains the error):

I am not used to content provider.Please help.

Solution

I didn't understand what was the problem.But it was solved when I changed onActivityResult to

        switch (requestCode) {
            case 7:
                if (resultCode == RESULT_OK) {
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                    videoPlayer.setVideoURI(data.getData());
                    videoPlayer.requestFocus();
                    videoPlayer.start();
                }
        }
